Industrial Downdraft Tables — Micro Air vs. Plymovent vs. ICAP
You’re trying to pick the right downdraft table for welding, grinding, or fabrication. Three brands compared side by side — or skip the comparison and order an ICAP table online today: ships in 48 hours from $8,995, freight included.
Your right answer depends on what you’re cutting, how often, and how big your work pieces are. There’s no single “best” industrial downdraft table — just the right match for your application. The good news: you have a fast self-service path and an engineered path, and you can use this page to jump straight to whichever one fits.
We’re authorized dealers for Micro Air Extreme Air-Max, Plymovent DraftMax, and the ICAP Self-Cleaning Downdraft Table Quick Ship line — kept in stock for 48-hour shipping in 4 sizes. Since we sell all three downdraft table manufacturers, we have no reason to push one over another. Here’s the honest breakdown.
Quick answer: Micro Air gives you more CFM and larger work surfaces — ideal for heavy grinding and big parts, plus wet downdraft tables for combustible metals. Plymovent DraftMax has superior backdraft capture for welding-heavy shops. ICAP Quick Ship gets you a working table this week — order online from $8,995, ships in 48 hours, freight included to AZ/CA/NV/NM/UT. All three are professional-grade.

Read this before you order online
When you configure and order online, you’re sizing the table yourself based on your application. That’s the right path for straightforward bench welding, grinding, and metal fab — and it’s faster and cheaper. Online orders are self-service and self-configured, which keeps them separate from our engineered-system program. If you need documented NFPA 660 compliance, an OSHA citation response, or a stamped analysis, book a free assessment instead — that’s the designed-and-installed path. Or call us first at 602-456-9661 — 10 minutes on the phone beats a wrong-size return.
Downdraft Table Manufacturers Compared
Micro Air
Extreme Air-Max Series · Since 1969
If you’re grinding big parts or pushing high dust volume, you want CFM and surface area — and that’s where Micro Air leads. Their high-CFM, modular Extreme Air-Max tables use a proprietary Roto-Pulse cleaning system that delivers 30–40% better cartridge cleaning than standard reverse-jet pulse. You get four self-contained sizes plus ducted and wet-collection models to match your work.
Best For:
→ Heavy grinding and deburring
→ Large work pieces (up to 4’×8′ surface)
→ High-CFM applications (up to 6,000 CFM)
→ Combustible dust with HYDROMAX wet tables
→ Shops needing maximum configurability
Plymovent
DraftMax Series · 50+ Years Worldwide
If your bench is mostly welding, your fume rises fast — and Plymovent’s DraftMax is built for exactly that. You get dual capture: 80% of the air pulls through the back panel, 20% through the work grid, so the fume is caught before it reaches your breathing zone. Pick from light-duty, heavy-duty, HEPA, Eco (ducted), and plasma cutting configurations.
Best For:
→ Welding-heavy shops (MIG, TIG, stick)
→ Stainless steel welding (HEPA/W-3 option)
→ Vocational schools and training facilities
→ Shops needing backdraft + downdraft capture
→ Plasma cutting (dedicated grid model)
ICAP Quick Ship — In Stock and Ready
Don’t need a custom-engineered system? Our ICAP self-cleaning downdraft tables ship in 48 hours from $8,995 — same 99.97% nanofiber filtration, push-button pulse cleaning, freight included to AZ/CA/NV/NM/UT.
Downdraft vs. Backdraft Tables — What’s the Difference?
If you’re cross-shopping “downdraft” and “backdraft” tables, you’re really asking one question: which direction does the table pull contaminated air? The answer should match what you’re actually doing — grinding throws particles down, welding sends fume up.
Downdraft — pulls air down through the grate
A downdraft table draws contaminated air straight down through a grated work surface into the filter below. Heavy particles — grinding sparks, metal fines, sanding dust — fall in that direction naturally, so downdraft capture is highly effective for grinding, deburring, and dry metal fab.
Best when:
→ You’re grinding, deburring, or sanding
→ Parts lie flat on the work surface
→ Dust and sparks fall rather than rise
Backdraft — pulls air back and across
A backdraft table adds a rear panel that pulls air horizontally behind the work piece. Welding fume rises fast and drifts back, so a backdraft panel catches it before it reaches the breathing zone. Plymovent’s DraftMax uses an 80% backdraft / 20% downdraft split built specifically for welding.
Best when:
→ You’re welding (MIG, TIG, stick)
→ Fume rises off vertical or tall work
→ You want capture behind the operator’s hands
Most modern industrial tables blend both. A combined downdraft + backdraft table handles a mixed shop — weld in the morning, grind in the afternoon — without two separate stations. If your work is split, lean toward a table with a strong backdraft panel; if it’s grinding-dominant, prioritize downdraft CFM and a steel grate. Not sure which way your dust actually moves?

Ducted Downdraft Tables — Connect to Your Collector
No integrated filtration — these tables connect to a central baghouse or cartridge collector via ductwork. Lower upfront cost per table, better for multi-station shops.
Micro Air — Ducted Dry Tables
If you already run a central collector, these unpowered tables tie straight into it. You connect them to an external vacuum source or central dust collector, and the dual inlet keeps your airflow even across the surface.
DDT4830 — 48″ × 30″ work surface, dual inlet
DDT7230 — 72″ × 30″ work surface, dual inlet
Options: Back and side shields, soft-touch mat, casters.
Plymovent — DraftMax Eco (Ducted)
If you want DraftMax backdraft capture but you’re routing to your own collector, the Eco drops the cartridges. You connect it to an external fan and filtration system, keep the 80% backdraft / 20% downdraft split, and set your working height (31.5″–37.5″). Optional spark arresters protect your backdraft panel.
DraftMax Eco — 54″ × 30″ work surface
Recommended extraction: ~1,770–1,900 CFM
Max load: 550 lbs
Weight: 330 lbs
When Ducted Makes Sense
Ducted tables cost less per station because you’re sharing one central collector across multiple workstations. The tradeoff: you need ductwork, a collector, and potentially explosion protection.
5+ stations? → Ducted is usually cheaper overall
1–4 stations? → Self-contained is usually simpler
Combustible dust? → Wet table + wet collector (see below)
Mix and Match Stations
Running both dry grinding and combustible metal work? You can duct dry tables to a cartridge collector and route the combustible stations to a separate wet collector. We size both loops so airflow stays balanced.
For a multi-loop layout, book a free assessment and we’ll model it before you buy ductwork.
Wet Downdraft Tables for Aluminum & Combustible Metals
If you’re grinding aluminum, magnesium, or titanium, a dry downdraft table is the wrong tool — those metal dusts are combustible, and collecting them dry creates an explosion risk. A wet downdraft table is the answer.
How a wet downdraft table works
When you grind reactive metal, you need the dust wet before it can ignite. A wet downdraft table pulls your contaminated air down through a water bath instead of a dry filter, capturing and deactivating volatile fines on contact — so you skip the explosion venting, isolation valves, and chemical suppression a dry table would force on you.
Micro Air HYDROMAX wet downdraft tables (WCDDT series) come in 24″, 48″, and 72″ widths and pair with a HYDROMAX wet collector.
When you need one
→ Grinding or finishing aluminum
→ Magnesium or titanium dust
→ Mixed combustible metal fines
→ Any process flagged combustible under NFPA 660 KSt testing
Wet downdraft tables are an engineered application — sizing depends on your metal, your rate, and your layout. This is the designed-and-installed path, and it carries our pass-or-free compliance guarantee: when our team performs the dust hazard analysis, sizing, and installation, your system passes inspection or we fix it at no charge.
Head-to-Head Feature Comparison
*The pass-or-free compliance guarantee applies only when our team performs the dust hazard analysis, sizing, and installation on an engineered system. Online self-service orders are configured by the buyer and not part of that program.
