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?

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 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. 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 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):

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):

Transport Velocity 2000 FPM

Minimun Face Velocity 785 FPM

Mist:

Capture Velocity 100 FPM

Transport Velocity 2250 FPM

Minimum Face Velocity 1766 FPM

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?

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.

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.

Updraft and Overhead hoods, completely or partially enclose the process or contaminant generation point. For example: A Complete Enclosure would be a sealed “box” or similar type of configuratin where only minimal openings exist and the contaminated air is sucked up and away. The enclosing hood is preferred wherever the process configuration and operation will permit. A Partial Enclosure would be an “open box” (i.e.: with the lid cut off). An inward flow of air through the enclosure opening will contain the contaminant within the enclosure and prevent its escape into the outside work environment. If complete enclosure is not feasible, partial enclosure should be used to the maximum extent possible.
