This category lists 21 items for metalworking dust control: 10 complete machines and 11 JET accessories (hoses, reducer sleeves and replacement filters). The machines come from three brands - Baileigh, JET Tools and GMC Machine Tools - and cover four different approaches to the same problem: capturing abrasive grinding dust, sanding dust and metal chips before they reach your lungs, your machine ways and your electrical panels. Airflow across the ten machines runs from 472 CFM on the smallest bench-grinder stand up to 2,340 CFM on the largest cartridge collector and downdraft table. Motors run from 1/2 HP to 5 HP. All equipment sold here is new.
Metal dust is not wood dust. It is heavier, it is abrasive enough to destroy a standard shop vacuum, and grinding sparks can ignite a cloth filter bag. Every machine in this category is built specifically for ferrous and abrasive debris: the JET units use a non-sparking aluminum fan blade and housing, the Baileigh MDC-1200-HD and MDC-3500-HD collectors replace the cloth bag with fire-resistant Teflon-coated filters, the Baileigh HD downdraft tables and the GMC table use a spark-arresting metallic pre-filter, while the DDTM-5922 publishes only fire-resistant air filters, and the GMC wet collector drops the dust into a water tank instead of a filter. Choosing among them comes down to four questions: how many machines you are hooking up, how much floor and ceiling you have, what voltage and phase you can supply, and how fine the dust is that you need to hold back.

The four types of metalworking dust collection in this category
Grinder and sander stands
The JET JDCS-505 is a universal dust collection stand: it mounts a bench grinder or a benchtop belt and disc sander on top and pulls the dust down at the source. It is rated at a maximum of 472 CFM through two 3 in. inlets, runs on 1/2 HP at 115V single phase, listed at 20A, weighs 110 lb, and is built from 16-gauge steel. Chips fall into a metal drawer; the filter is replaceable and rated at 90 percent efficiency at 50 microns. Two removable water pots give it the features of a pedestal stand as well as those of a dust collector. Sound is rated at 75 dB at 10 ft, and it carries a CSA/CUS certification. This is the entry point for a single grinding station, not a shop-wide system.
Cabinet and cyclone collectors
The JET JDC-501 is a cabinet-style collector for belt and disc finishing machines: 1-1/2 HP on 115/230V single phase, a maximum of 490 CFM, and a filter rated 99 percent efficient at 5 microns - a much finer cut than the stand's 50-micron filter. It measures 30-5/8 x 20-7/8 x 29 in. with wheels, weighs 157 lb, rides on four casters with two handles, and its listing describes two 3 in. inlets so a pair of machines can share it. Noise is rated at 75 dBA at 5 ft.
The Baileigh MDC-1800 is a cyclone-style unit rated at 1,450 CFM from a 3 hp motor on 220V single phase, with three 4 in. chutes for connecting multiple machines. Heavy chips settle into a removable metal drawer, a fireproof bag catches the larger airborne particles, and a fireproof paper filter rated at 5 microns handles the exhaust. It weighs 320 lb and runs at 85 dB at full power - the loudest machine in the category. Read one restriction on its listing carefully: the MDC-1800 is not to be used with surface grinders.
The two Baileigh HD cartridge collectors are the step up. The MDC-1200-HD produces 1,100 CFM from a 1.5 hp motor on 110V, which is unusual - it is the only cartridge collector here that plugs into ordinary 110V power. The MDC-3500-HD produces 2,340 CFM from a 5 hp motor on 220V three phase. Both use a 15 in. x 26 in. filter, a pulse-clean cartridge system, a HEPA filter as standard equipment, a magnetic pressure gauge, tool-less filter maintenance, full steel construction, and both are rated at 78 dB. Both are listed as CSA - U.S. certified.
Downdraft tables
A downdraft table is a workbench that is also the collector: the operator grinds, sands or deburrs directly on a perforated surface and the dust is pulled straight down instead of drifting across the shop. Four are listed here.
- Baileigh DDTM-5922 - a 59 in. x 22 in. table with a 3 mm thick stainless steel work surface, running on 110V power with fire-resistant air filters (16 in. x 20 in. x 1 in.). It is self-contained, so no external extraction system is required. Spec-table maximum is 1,790 CFM from two 1.5 hp motors.
- Baileigh DDTM-4840-HD - a 48 in. x 40 in. working area, 1,350 CFM from a 2 HP 230V three-phase motor, air pulse cleaning, and a three-stage filter set: an aluminum pre-filter (11.3 x 23.8 x 0.86 in.), two cartridges (11.25 in. diameter x 13 in. long) and an 18 x 20 x 5.9 in. HEPA. Maximum table load is 1,543 lb evenly distributed over 80 to 100 percent of the surface; the listing also publishes the derated figures for concentrated loads, down to 192 lb over 10 percent of the surface.
- Baileigh DDTM-8052-HD - the largest unit in the category. The listing gives a 78 in. x 52 in. working area, and the spec table gives 2,340 CFM from a 5 HP 230V three-phase motor, two aluminum pre-filters, six cartridges and a HEPA stage. Maximum table load is 1,764 lb evenly distributed over 80 to 100 percent of the surface. It weighs 1,650 lb.
- GMC DDT-6137 - a 61 in. x 37 in. table, 1,550 CFM, 4 HP on 220V three phase, table height 39 in., machine dimensions 79 x 46 x 80 in., maximum table load 1,650 lb, and a graded three-stage filter train: G2 spark-arresting metal pre-filter (11-1/4 x 25 x 7/8 in.), F7 cartridge (11-1/4 in. diameter x 13 in.) and an H13 HEPA (18 x 20 x 6 in.).
Both Baileigh HD tables ship fully assembled - uncrate, wire and use - and both include a HEPA filter, a fire-resistant cartridge filter, a spark-arresting metallic pre-filter, a magnehelic gauge, hinged side walls with a back wall, a work light, auxiliary 110V and air tool outlets, a 12 in. overhang, casters and leveling feet. The GMC DDT-6137 also includes a 110V work light, an air tool outlet, four caster wheels and leveling feet.
Wet collection
The GMC WDC-2100 Finish Pro is the only wet collector here and the only machine with a fully welded stainless steel cabinet and a stainless impeller. Its cabinet is welded stainless steel, the precision-balanced impeller is stainless and direct-coupled to the motor, and dust is removed from the airstream by internal spray inducers that make the particles settle into a water tank rather than load a filter. Inlet rating is 2,100 CFM through an 8 in. inlet opening, driven by a 5 HP TEFC motor at 208-230/460V three phase, 60 Hz, drawing 20A at 220VAC or 10A at 440VAC. The front door is removable for cleaning and carries an explosion relief flap; an automatic water level control lets you connect a water supply line so the tank stays at the correct operating level, and a stainless cleaning tool is provided for removing settled grinding dust. The listing specifies it for use with the GMC FP-2560 and FP-4075 wide belt sanders - that is a stated compatibility, not an included machine.
Power, space and hookups
Voltage and phase eliminate more models than airflow does, so check this first. Three machines run on ordinary 110/115V supply: the JET JDCS-505 (115V, single phase), the Baileigh MDC-1200-HD (110V) and the Baileigh DDTM-5922 (110V); the Baileigh listings publish the voltage without stating the phase. The JET JDC-501 is dual-voltage 115/230V single phase. The Baileigh MDC-1800 needs 220V single phase. Five machines require three phase: the MDC-3500-HD (220V), the DDTM-4840-HD and DDTM-8052-HD (230V), the GMC DDT-6137 (220V) and the GMC WDC-2100 (208-230/460V). If your building has no three-phase service, your practical choices in this category are the two JET units, the MDC-1200-HD, the MDC-1800 and the DDTM-5922.
For floor space, the listings publish overall dimensions for two machines only: the JET JDC-501 at 30-5/8 x 20-7/8 x 29 in. with wheels, and the GMC DDT-6137 at 79 x 46 x 80 in. with a 39 in. table height - note that 80 in. overall height, since it decides whether the machine clears a low ceiling or an overhead door. For the other models, plan around the published working area or footprint clues and confirm crated dimensions on the model's spec sheet before you commit floor layout. Weight also drives your unloading plan: the range runs from 110 lb for the JDCS-505 to 1,650 lb for the DDTM-8052-HD, so the larger units need a forklift or a dock.
Compressed air is worth asking about. The MDC-1200-HD, MDC-3500-HD, DDTM-4840-HD and DDTM-8052-HD all use pulse cleaning to blow the cartridges clear, and the Baileigh HD tables and the GMC DDT-6137 include an air tool outlet at the workstation. The listings do not publish the required air pressure or consumption for pulse cleaning, so confirm that on the manual for the model you choose. The GMC WDC-2100 is the only unit that asks for a water connection, and even that is optional - the automatic level control simply lets you tie it to a supply line instead of topping the tank by hand.
Filtration, fire and spark control
The filtration specs on this page span a very wide range and they are not interchangeable. At the coarse end, the JET JDCS-505 filter is rated 90 percent at 50 microns - fine for catching grinding grit at a single pedestal. The JET JDC-501 filter is 99 percent at 5 microns. The Baileigh MDC-1800 uses a 5-micron paper filter behind a fireproof bag. At the fine end, the MDC-1200-HD, MDC-3500-HD, DDTM-4840-HD, DDTM-8052-HD and GMC DDT-6137 all include a HEPA stage as standard, with the GMC unit specifying its stages by filter class: G2 metal pre-filter, F7 cartridge, H13 HEPA. If your goal is to keep respirable dust out of the breathing zone rather than just to keep chips off the floor, the HEPA-equipped machines are the relevant group.
Ignition control is designed in differently by each brand. JET uses a non-sparking aluminum fan blade and housing so sparks never meet a steel impeller. Baileigh's HD collectors removed the cloth bag entirely and use fire-resistant Teflon-coated filters; the HD tables add a spark-arresting metallic pre-filter ahead of the cartridge. GMC's wet collector quenches the dust in water and vents an event through the explosion relief flap on the door. Two figures on hose transport are published and are useful when you plan duct runs for heavy chips: maximum hose velocity is 3,465 SFPM on the JDCS-505 and 5,610 SFPM on the JDC-501.
Certifications declared on these listings
Only cite what the manufacturer states. In this category: the Baileigh MDC-1200-HD and MDC-3500-HD are listed as CSA - U.S. certified; the DDTM-4840-HD and DDTM-8052-HD are listed as CSA listed and as being under the OSHA decibel limit, meaning the listing states hearing protection is not required for the machine noise itself. The JET JDCS-505 is CSA/CUS certified and the JDC-501 is CSA/US certified. The GMC DDT-6137 is described as ISO 9001 certified - that is a manufacturer quality-system certification rather than a product listing - and as meeting OSHA safety requirements, with overload protection and a disconnect switch. The Baileigh and JET products carry a California Prop 65 warning, and Baileigh collects sales tax on orders shipped to California and Wisconsin. The Baileigh MDC-1800, the Baileigh DDTM-5922 and the eleven JET accessories publish no certification of any kind. No unit in this category is listed with an ETL or ASME rating, so do not assume one.

Hoses, reducers and replacement filters
Eleven JET accessories complete the category. Six flexible heat-resistant hoses are stocked in two temperature ratings and three sizes: 2 ft lengths in 2 in. and 3 in. diameters rated to 180 degrees F, and 8 ft lengths in 3 in. and 4 in. diameters in both a 130-degree and a 180-degree version. Short 2 ft hoses suit a tool sitting right beside the collector; the 8 ft lengths cover longer runs to a machine across the bench.
Three black plastic reducer sleeves step a 3 in. port down to 2-1/2 in., 2 in. or 1-1/2 in. Reducing the port raises air velocity at the point of capture, which matters with heavy metal chips. All three are built for the JDCS-505. Two replacement filters are listed: a pair for the JDC-501 rated 99 percent efficient at 5 microns, and a single filter for the JDCS-505 rated 90 percent at 50 microns, measuring 6-3/4 x 2-5/8 x 13-1/2 in.
Where the listings disagree
Three specification conflicts on these pages are worth flagging. In each case the product name and the manufacturer spec table are the reliable source, not the marketing paragraph or the shipping-weight field.
- DDTM-5922 motors and airflow. The narrative paragraph claims two 5 hp motors producing 1,790 CFM per motor. The spec table lists two 1.5 hp motors and a maximum of 1,790 CFM. Use the spec table: two 1.5 hp motors, 1,790 CFM maximum.
- MDC-1200-HD weight. The spec table gives 620 lb, while the catalog weight field shows 700 lb. Use the 620 lb spec for the machine and ask us to confirm the crated weight before you plan handling.
- GMC DDT-6137 weight. The listing's shipping weight field shows 100 lb, which cannot be right for a 4 HP three-phase table. The spec table gives a machine weight of 1,150 lb. Plan for 1,150 lb.
Frequently asked questions
What size collector do I need for a single bench grinder?
The JET JDCS-505 stand is built exactly for that job: it mounts any brand of bench grinder or benchtop belt and disc sander and pulls 472 CFM through two 3 in. inlets on standard 115V power. If you want to serve two finishing machines and hold back finer dust, the JDC-501 cabinet unit offers 490 CFM with a 99 percent at 5 micron filter and rolls on casters between stations.
Can these units collect aluminum or other combustible metal dust?
None of the listings in this category states a combustible-dust or explosion-protection rating for aluminum, magnesium or titanium. What they do declare are ignition-control features: non-sparking aluminum fans and housings on the JET units, fire-resistant Teflon-coated cartridges and spark-arresting metallic pre-filters on the Baileigh HD models, and water-bath collection with an explosion relief flap on the GMC WDC-2100. Combustible metal dust is a separate engineering problem governed by your local authority having jurisdiction. Confirm suitability with the manufacturer and your safety authority before ordering for that application - do not infer it from a spark-arrest feature.
Do I need three-phase power?
Not necessarily. Five machines here run without three-phase service: the JET JDCS-505 (115V, single phase), the JET JDC-501 (115/230V, single phase) and the Baileigh MDC-1800 (220V single phase), plus the Baileigh MDC-1200-HD (110V) and DDTM-5922 (110V), whose listings publish the voltage without stating the phase. The MDC-3500-HD, DDTM-4840-HD, DDTM-8052-HD, GMC DDT-6137 and GMC WDC-2100 all require three phase.
Should I buy a collector or a downdraft table?
A collector is ducted to a machine and captures dust at that machine's port; a downdraft table is the work surface itself and captures dust generated by hand work such as grinding, sanding and deburring. If your dust comes from a belt sander, a disc finisher or a grinder with a port, a cabinet or cartridge collector is the fit. If an operator works freehand on parts, a downdraft table captures at the source and gives you a rated work surface at the same time - up to 1,543 lb on the DDTM-4840-HD and 1,764 lb on the DDTM-8052-HD, both evenly distributed over 80 to 100 percent of the surface, and a maximum table load of 1,650 lb on the GMC DDT-6137, whose listing does not publish a load-distribution condition.
How loud are these machines?
Published figures range from 75 dB at 10 ft on the JDCS-505 and 75 dBA at 5 ft on the JDC-501, through 78 dB on both Baileigh HD cartridge collectors, up to 85 dB at full power on the MDC-1800. The Baileigh DDTM-4840-HD and DDTM-8052-HD are described as being under the OSHA decibel limit without a published number, and the GMC WDC-2100 uses a sound suppressor motor cover. No sound rating is published for the GMC DDT-6137; consult that model's spec sheet.
What about shipping?
Two items in this category are listed with free shipping: the GMC WDC-2100 wet dust collector and the GMC DDT-6137 downdraft table. For every other item, check the individual product page for its shipping terms. Given machine weights up to 1,650 lb, confirm your receiving setup - dock, forklift or liftgate - and ask us for the crated weight before the machine arrives.
