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?

Exhaust Fans
Fans for air make up and exhaust are quite often a difficult product to find when designing a simple ducted local exhaust system. Here we offer a variety of "LEV" (Local Exhaust & Ventilation) fans specifically designed to meet the demands of such systems. These Fans are able to handle specific applications such as: - Corrosive Fumes - Abrasive Dusts - Proper Flow and Static Pressure for a particular application.

Please feel free to contact one of our System Design Technicians for help in selecting the right fan for your application.
Extraction Arms
Capture at Source Extraction Arms are used to capture airborne contaminants before the contaminants have a chance to reach the workers' breathing space.

Available in several different designs:
  • Internally Supported
  • Externally Supported
  • Telescopic
  • Mild or Stainless Steel Construction
  • Lengths: Up to 45'
  • 2.5" to 8" Diameter's Available
Typically the Extraction Arms are connected to a fixed extraction fan, Filter system or dust collector via direct mounting or a "Header Type" duct system.

For more info, please see the products and associated documentation listed below.
Industrial Hose & Duct Work
Lev-Co offers a wide variety of lightweight, flexible, abrasive resistant, heat tolerant, innovative technical hoses to provide solutions for a wide range of industrial & Automotive applications. Here are some general design velocities when using "CAPTURE" Hoods:

Smoke (e.g. Welding):
  • Capture Velocity 100 FPM
  • Transport Velocity 3000 FPM
  • Minimun Face velocity 2355 FPM

    Dust (e.g. Grinding):
  • Capture Velocity 500 FPM
  • Transport Velocity 4000 FPM
  • Minimun Face Velocity 4000 FPM

    Gas (e.g. V.O.C.'s):
  • Capture Velocity 50 FPM
  • Transport Velocity 2000 FPM
  • Minimun Face Velocity 785 FPM

    Mist:
  • Capture Velocity 100 FPM
  • Transport Velocity 2250 FPM
  • Minimun Face Velocity 1766 FPM

    The best way to protect mechanics and garage employees from harmful gases released from automotive vehicles such as cars & trucks is CAPTURE AT SOURCE. This means directly at the tailpipe.

    This process involves 3 steps:
  • 1. Capture of the gases at source through suction nozzles
  • 2. Transporting the gases through exhaust hoses to an exhaust fan
  • 3. Transport the gases to atmosphere.

    Below is a list of the information that needs to be gathered prior to selecting the appropriate VEHICLE EXHAUST ventilation system:
  • 1 – Max Engine HP
  • 2 – Max RPM engines to be run at:
  • 3 – Engine being run A - under load? or B - at idle?
  • 4 – Diameter of smallest and largest tailpipes?
  • 5 – Configuration of tailpipes? (EG: are they exposed, behind a grill, overhead stack, under carriage, etc…)
  • 6 – Voltage and Amperage available
  • 7 – Fixed or Portable system
