Overview

2X4 Downdraft Tables

Durable and reliable, the Sledge Tech 2' X 4' Downdraft Table is a portable unit designed to handle industrial duty applications. Harmful fumes, smoke and dust are captured right at the source, before they can enter your breathing space, so indoor air quality remains uncompromised. Whether you weld, grind, debur, cut, sand, finish, solder, paint or mix, the Sledge Tech 2' X 4' Downdraft Table is a versatile all-in-one solution.

The 2' X 4' Downdraft Table comes fitted with multi-stage spark arrestance baffles, industrial swivel casters and a push-button, reverse-pulse filter cleaning system to reduce maintenance. You can choose from a 1.5HP 1500 CFM single phase [120V] motor, or 3.0HP, three phase [230/460/575V] motor for higher capture face velocity and 2600 CFM of airflow. Single phase models include a 15' power cord for plug and play convenience.

With many options and accessories available, the Sledge Tech 2' X 4' Downdraft Table can be custom built to your specific needs.

FAQ

Common Questions

How do I know what CFM I need for a downdraft table?

Required CFM depends on the size of the work surface and the capture velocity needed for your process — heavier fume-generating work like welding typically needs more air movement per square foot than light sanding. As a general reference, our own Downdraft Tables line ranges from a 1,200 CFM Mini model up to 6,300 CFM on our largest 3'x8' and 4'x8' tables. Our team can size a table to your specific application; contact us for a recommendation.

What’s the difference between a dry downdraft table and a wet downdraft table?

A dry downdraft table pulls dust and fume through dry filter media, while a wet downdraft table (like our Storm series) draws air through a water bath, which captures sparks and combustible dust before they reach a filter. Wet tables are generally the safer choice for processes that generate hot sparks, aluminum or magnesium dust, or other combustible fines where a dry filter would pose an ignition risk.

What does a wet scrubber do that a standard dust collector can’t?

A wet scrubber routes contaminated air through a water bath or spray chamber rather than dry filter media, which makes it well suited to overspray from spray painting, and to dusts that are combustible, sticky, or otherwise poor candidates for dry filtration. Our Camfil Handte Wet Scrubbers line includes Vortex, Vortex Dual, and Venturi models for different airflow and contaminant loads.

How do I control hexavalent chromium exposure from welding stainless steel?

Hexavalent chromium is generated when welding or cutting stainless steel and other chromium alloys, and OSHA regulates exposure under 29 CFR 1910.1026. Source capture with a properly sized downdraft table or fume extraction system is the primary engineering control; see our Safety guide to Hexavalent Chromium for exposure limits and a fuller overview.
