Back & Side Draft Systems
Back and Side Draft Tables are similar to Down-Draft Tables. “Back Draft” and “Cross Draft” are ideal solutions when extraction methods such as self-supporting extraction arms and other such systems prove to be inappropriate for the application.The contaminated air is drawn in from the back or side panels of the work area. These units come with or without filtration systems and can also be combined to create complete enclosures for whatever the application might be

Some important points to consider when purchasing:
  • What is the velocity or the air required to pull the fumes and dust horizontally into the table? (Capture Velocity: Add up the CFM for all of the inlets that will run at once)
  • What velocity at the Table surface is required to achieve the appropriate Capture Velocity? (Face velocity)
  • Do I have enough filter media in the collector? (Air to cloth ratio)
  • 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?

Centrally Ducted Filter Units
Centrally Ducted Dust Collectors such as these are ideal for large shops and centrally ducted applications. Most of these solutions are based upon self-cleaning filter cleaning systems to help reduce filter costs. In addition, Water based filtration systems are available for certain explosive and flammable applications.

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?

Ducted Air Cleaners
Ducted Air Cleaners are used in a variety of applications where the filter selection often requires a specific configuration. With these collectors you can select a variety of particulate, liquid or gas phase filters such as “HEPA” filters, “Mist Agglomerators” and “Gas Adsorbers” respectively. These systems are available with or without pre-engineered and installed fan packages.

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
  • Minimum Face Velocity 1766 FPM
  • Dust, Fume & Vapor Control Booths
    Environmental Control Booths allow operators to work on a variety of components while assuring worker comfort and visibility within the critical area. These solutions also ensure that the "dust produced within the booth... stays in the booth..." Some important points to consider when purchasing:
  • How large does the booth have to be?
  • Is the air speed through the work zone high enough to protect the worker?
  • What is the noise level? (inside and outside the booth)
  • Will it stand up to your environment (Eg: is it made from Plastic or Steel?)
  • Filter cleaning: is it easy to clean? Does the filter cleaning system really work?
  • What will be my filter costs per year (in welding you can use lbs of welding wire…)
  • What is the filtration efficiency
  • Are there any tertiary risks such as fire, explosion, etc?

    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:

  • Per Work Station Filter Units
    Per Station Dust Collectors such as these are ideal for 'Cell Based' manufacturing and work stations. Most of these solutions are based upon self-cleaning filter cleaning systems to reduce filter costs.Water based systems are also available for certain explosive and flammable applications

    Some important points to consider when purchasing:
    • What is the Total Flow Rate? (How many CFM's are needed to capture the contaminants)
    • What is the exact resistance (filter and capture device losses) required for the fan to overcome?
    • Do I have enough filter media in the collector?(Air to cloth ratio)
    • Will it stand up to your environment (Eg: is it made from Plastic or Steel?)
    • Filter cleaning: Does the filter cleaning system really work in your application?
