The Only Welding Fixture Table That Cleans the Air While You Work.
The Fume Dog Platen Downdraft Table is a CNC-machined cast steel welding and fabrication fixture table with industrial-grade downdraft fume extraction built directly into the structure — capturing welding smoke, grinding particulates, and toxic fumes at 400 FPM through the same 5/8" holes you use to clamp your work. At 700 lbs static load capacity and with a MERV 15 nanofiber filter and Air Stream Filter Cleaner, it's the precision fixturing table that doesn't ask you to choose between clean welds and clean air.
[Return Policy exception: Fume Dog products are an exception to The Maker's Chest standard returns policy, and all sales are final. However, this does not mean we do not have confidence in these products - in fact, the Fume Dog products come with a 10-year warranty on all major structural components.]
What a Platen Table Is — and Why It Changes How You Weld
If you've been working off a standard welding table, you know the frustration: parts shift, clamp positions are limited, and getting complex assemblies square and repeatable takes longer than the welding itself.
A platen table (also called an acorn platen table or fixture welding table) solves this at the foundation. The cast steel surface is machined with a grid of 5/8" holes on consistent centers across the entire top and sides — accepting standard 5/8" or 16mm fixturing clamps, stops, angle plates, V-blocks, and tooling from virtually any third-party manufacturer. You clamp exactly where you need to, without hunting for a good jaw position. Parts hold precisely where you put them. Assemblies come out square and repeatable, job after job.
The Fume Dog Platen Downdraft Table adds one more layer to this: the same holes that fixture your work also pull fumes directly downward through the table surface, into the extraction and filtration system below. Two problems solved by the same engineered feature.
CNC-Machined Cast Steel. Flat to a Fraction of a Millimeter.
Flatness is everything on a fixturing table. If the surface has any bow or warp, your parts don't sit flat, your assemblies don't come out square, and your clamps don't engage properly. That's why the Fume Dog Platen table surface is 5/8" cast steel, CNC machined for verified flatness — the same standard used in professional tool and die and precision fabrication environments.
The tabletop is machined to ensure it is completely flat and suctions 400 feet per minute of fumes and sparks through the .625" diameter holes.
The cast steel surface is also designed to resist weld spatter adhesion — spatter lands and releases cleanly rather than bonding to the surface, keeping the table functional without constant maintenance. All holes use a friction fit for fixturing tools, which means tooling stays where you put it without shifting during the weld.
Multi-Stage Filtration Built for Real Welding Conditions
A platen table used for production welding and grinding generates not just fumes but sparks, metal particulates, and spatter fragments. The Fume Dog filtration system is designed for exactly that environment:
The filtration system uses a metal mesh pre-filter and spark trap, followed by a baffle plate, and then a fire-retardant MERV 15 nanofiber filter.
Stage 1 — Metal Mesh Spark Trap: Captures sparks and larger metallic debris before they reach the primary filter, preventing fire risk and protecting the filter media from physical damage.
Stage 2 — Baffle Plate: Further slows and separates larger particulate from the airstream before the primary filter.
Stage 3 — MERV 15 Fire-Retardant Nanofiber Filter: High-efficiency filtration capturing very fine metal oxide particles and fumes — including hexavalent chromium from stainless steel welding — at the efficiency level required for a genuinely safe breathing environment.
The Air Stream Filter Cleaning System continuously extends the life of the MERV 15 filter by 5 to 6 times compared to conventional filter designs — meaning dramatically fewer replacement intervals and lower ongoing operating costs for a production shop.
700 Pounds. Heavy Parts. No Problem.
The Platen Downdraft Table has a 700 lb static load capacity — sufficient for heavy fabrications, large structural sub-assemblies, and multi-part fixture setups that would overwhelm a lighter-duty welding table. The cast steel construction and powder-coat finish are built for continuous industrial use, not occasional workshop duty.
The clamping system accepts standard third-party 5/8" and 16mm fixturing tooling — Siegmund, Demmeler, and equivalent systems are all compatible. You're not locked into proprietary clamps at a markup. The grid pattern covers the full table top and sides, giving you clamping access from virtually any angle for complex three-dimensional assemblies.
The 36" × 48" work surface accommodates medium-to-large fabrication work while keeping the table footprint manageable in a production shop environment.

Frequently Asked Questions about Fume Dog Platen Downdraft Table Fume Extractor
Q: What's the difference between the Platen Downdraft Table and the standard Fume Dog Downdraft Table (DDT)?
A: The standard DDT has a perforated steel work surface designed for general welding, grinding, and fabrication work, with removable side and back walls, a light kit, tool tray, and an optional 3-in-1 conversion to portable or wall-mount configuration. The Platen DDT has a CNC-machined cast steel surface with 5/8" fixturing holes for precision clamping and assembly work — it's a proper fixture welding table with fume extraction built in. It does not include the 3-in-1 conversion option, removable walls, or tool tray of the standard DDT. If your work involves precise fixturing, repeatable assembly, or complex multi-part setups where part position is critical, the Platen is the right table. If you need general-purpose welding and grinding extraction with more configuration flexibility, the standard DDT may be a better fit.
Q: What fixturing tooling is compatible with the 5/8" holes?
A: The table accepts any standard 5/8" or 16mm fixturing tooling — including clamps, stops, angle plates, V-blocks, squares, and supports from major manufacturers like Siegmund, Demmeler, and equivalent systems. The friction fit of the holes holds tooling in position during welding without requiring additional fasteners.
Q: How flat is the table surface?
A: The tabletop is made of cast steel and CNC machined for flatness. This is the same surface specification used in professional tool and die and precision fabrication environments. For assembly welding where squareness and repeatability are critical, a properly machined flat reference surface is the foundation everything else depends on.
Q: How does the downdraft capture work through the 5/8" fixturing holes?
A: The 1.5 HP motor draws air downward through the grid of 5/8" holes across the entire table surface at 400 FPM. Fumes, smoke, and particulates generated at the work surface are pulled down through the holes, through the spark trap and baffle stages, and into the MERV 15 nanofiber filter below. The same holes that fixture your clamps are the same holes that extract fumes — the dual function is engineered into the surface geometry.
Q: What is the Air Stream Filter Cleaning System?
A: It's a built-in filter maintenance mechanism that uses a controlled air stream to dislodge accumulated particulate from the MERV 15 nanofiber filter media — actively extending filter life rather than allowing gradual loading until full replacement is required. The Air Stream Filter Cleaner extends filter life 5 to 6 times over traditional reverse pulse systems, which translates directly to fewer filter replacements and lower annual operating costs for a production shop.
Q: Does the Platen DDT have a spark trap? A: Yes. The filtration system includes a metal mesh pre-filter and spark trap, followed by a baffle plate, before air reaches the MERV 15 nanofiber filter. This prevents welding and grinding sparks from reaching and igniting the primary filter media — an important safety consideration for any table used regularly for grinding.
Q: Does it need ducting?
A: No. The Platen Downdraft Table is a filtered recirculating system — it processes extracted air through the multi-stage filter system and returns clean, filtered air to the shop. No ducting, no wall penetrations, and no conditioned air loss to the exterior. Connect power and it's operational.
Q: What power does it require?
A: 120V, single-phase — standard shop outlet power. The 1.5 HP motor is appropriate for a standard 20A circuit. No special wiring or three-phase power required.
Q: What welding processes is it designed for?
A: MIG, TIG, Stick welding, and grinding at one to two shifts per day. The spark trap and fire-retardant filter make it suitable for grinding applications that produce high spark loads — an important distinction from filtration systems not designed for grinding use.
Q: Can I weld stainless steel on this table?
A: Yes. The MERV 15 nanofiber primary filter is rated for fine particle capture including hexavalent chromium, the carcinogenic compound generated when welding stainless steel. The filtration system provides the level of protection required for regular stainless steel welding operations.
Q: What is the Returns Policy on the Fume Dog?
A: Given the nature of how a fume extractor is used, it is no longer a "new" product after first use, given contaminants which enter the filtration system. As such, Fume Dog products are an exception to The Maker's Chest returns policy, and all sales are final.
