#05 - Down Draft Tables


Down Draft Tables. Sometimes the best solution for extracting welding fumes is right on the table.This is generally referred to as a Down Draft Table. The Downdraft Table serves as both a workbench and an air cleaner.

A rigid grill supports the product, while an air cleaner below draws smoke and fumes down and away from the worker's breathing zone. A worker can weld, grind, and cut on the surface of the table while dust and fumes get sucked away from breathing air space


Some important points to consider when purchasing:

  • What is the velocity or the air required to pull the fumes and dust downward into the table (Capture Velocity)? (Add up the CFM for all of the inlets that will run at once)
  • What is velocity at the Table surface required to achieve the appropriate Capture velocity (Face velocity)?
  • Do I have enough filter media (Air to cloth ratio) in the collector?
  • Will it stand up to the working environment (Eg: is it made from Plastic or Steel?)
  • Filter cleaning: Does the filter cleaning system really work in your application?
  • What will be my filter, maintenance and energy costs per year?
  • Are there any tertiary risks such as fire, explosion, etc, that I need to consider?


    For more info, please see the products and associated documentation listed below.

    (05-15) Sledgehammer Series Downdraft Tables
    The 'Sledgehammer' © series downdraft tables are designed to be a dual purpose Work station and Extraction solution.

    These tables draw contaminants away from workers’ breathing zone without hindering movement. Additionally, they provide a the most durable ¼” steel plate work surface (36” X 24”) on the market. Hence the name “Sledgehammer” ©

    The SLEDGEHAMMER is equipped with Jet-Pulse Cleaning that allows simple cleaning of the filter, which reduces filter costs dramatically*.

    Applications Include filtering of contaminants from the following applications: welding, grinding, de-burring, plastics, composites, sampling, batching, weighing, soldering, and finishing processes

    All contaminated air is filtered and returned to the facility.

    Please select filter options according to your application… when proper filters are selected, all ‘’Sledgehammer’’ © series downdraft tables comply to all Local and Federal clean air requirements.

    Need a larger work surface? Quite often the area at which the fume or contaminant is generated is much smaller than the work table required… In these cases, either place the “sledgehammer” © series table in the middle of 2 or more work tables or bolt multiple downdraft tables together (Contact your distributor for quantity discounts).
