Ambient Air Cleaners
Ambient Air Cleaners involve the use of large “Washable, Cleanable or Replaceable Media” filters. These units, both filter and re-circulate the air back into the work place Installation Configurations: Free Hanging "Negative Pressure" “Race Track” "Cross Dilution" Depending upon the designed air pattern, these systems "scrub" the ambient air of contaminants and the result is a dramatic reduction of airborne pollution. These systems are best used in combination with source-collection equipment.

Some important things to consider when purchasing these types of units:
  • What is the volume of the room you want to clean? (cubic dimension: L'xW'xH')
  • How many times would you like to change the air in your room? (eg: Welding=8 AC/H)
  • How much contaminant do I generate? (eg: dust, smoke, fume)
  • Where am I going to mount these units?
  • Can I use these units to create a negative pressure in my work area?
  • Do I want "throw away", "washable", "cleanable" or "self cleaning" filters?

    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?

    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):

    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

  • 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?
    • 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.
    Portable Filter Units
    Portable Dust & Fume Filter Units. Quite often “Clean Air” solutions are required throughout a work place. These units can be easily moved from location to location with ease while capturing dust and fumes where needed.

    Various Options in Filtering Systems Available:
    • Washable Filters
    • Cleanable Filters
    • Self-Cleaning Systems
    • Throw Away Filters
    All Units equipped with fan/motor assemblies to ensure adequate extraction at all times
