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?

    Capture At Source - Extraction Arms
    Capture at Source Extraction Arms are used to capture airborn 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'

    Diameters to suit Application: 2.5" through 8"

    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.

    Here are some questions you may want to consider when selecting an extraction arm:
    1. Is there any requirement Image (Good Looks)?
    2. What is the Budget $?
    3. Is it important for the product to be Ergonomically/easy to position?
    4. Is it important for the product to be Move into place and Stay in place (without additional process such as tightening joints)?
    5. What is the Diameter?
    6. Chemical resistivity for external components?
    7. Is there any requirement for Chemical resistivity for internal components?
    8. What is the Transport velocity to be maintained?
    9. What is the Noise level (Air noise generated as Air passes through the arm)?
    10. What is the Lbs of force required to position into place?
    11. What is the acceptable Flow rate and pressure drop?
    12. Range of motion (Does it move to where they the arm to move and will they arm stay in this position.)?
    13. Does the build up of contaminant on the internal surface of the extraction arm cause concern?
    14. Do we need to meet any codes (EG: Fire (Transport/Flammability, Explosivity, etc.)
    15. Are there any issues related to the build up of static electricity that should be mitigated?
    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-Dust Fume Vapor
    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):

    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

  • Portable Vehicle Exhaust
    When diesel engines are started inside a building, these toxic air contaminants are emitted into the breathing area. It is well known that continued exposure to these contaminants has been linked to cancer and other serious health disorders.

    Fire and EMS facilities, garages, maintenance shops, or anywhere that trucks, buses, heavy equipment, or fleets of vehicles are operated are especially vulnerable to these toxic pollutants.

    The only proven method requires a "source capture" system, however, a system that pulls 100 percent of the exhaust emissions outside the building, through sealed hose or piping.

    Lev-co offers a complete line of Portable Vehicle Exhaust solutions for all makes and models of engines and equipment.
    Vehicle Exhaust - Cars & Trucks
    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:
