Dust & Fume Filter Units - Portable
|
|
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
Some important points to consider when purchasing:
How easy is the unit too move?
Is it easy to use?
Does it fit through small doorways and between tables, etc…?
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 (e.g. in welding you can use how many lbs of welding wire…)
Do you need unit for Maintenance or Production Application?
Here are some general design velocities when using "CAPTURE" Hoods:
Smoke (e.g. Welding):
Capture Velocity 100 FPM
Transport Velocity 3000 FPM
Minimum Face Velocity 2355 FPM
Dust (e.g. Grinding):
Capture Velocity 500 FPM
Transport Velocity 4000 FPM
Minimum Face Velocity 4000 FPM
Gas (e.g. V.O.C.'s):
Capture Velocity 50 FPM
Transport Velocity 2000 FPM
Minimum Face Velocity 785 FPM

Dust & Fume Filters - Per Work Station
|
|
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?
Here are some general design velocities when using "CAPTURE" Hoods:
Smoke (e.g. Welding):Capture Velocity 100 FPMTransport Velocity 3000 FPMMinimum Face Velocity 2355 FPM

Dust & Fume Filters - Centrally Ducted
|
|
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
Some important points to consider when purchasing:
What is the Total Flow Rate? (Add up all the inlets that will run at once)
What is the exact resistance (filter and duct losses) required for the fan to overcome?
Do I have enough filter media (Air to cloth ratio) in the collector?
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?
Here are some general design velocities when using "CAPTURE" Hoods:

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?
Here are some general design velocities when using "CAPTURE" Hoods:
Welding/Down Draft:Capture Velocity 100 FPMTransport Velocity 3000 FPMMinimum Face Velocity 150 FPM
Grinding/Down Draft:Capture Velocity 200 FPMTransport Velocity 4000 FPMMinimum Face Velocity 300 FPM

Mist Collectors
|
|
Mist Collectors are for a variety of mist producing applications such as:
CNC Machining and Coldheading Applications.
These filters are "SELF-DRAINING" and it is important that the amount of dust being captured by these systems does not exceed more than 5% of the total extracted pollutant.
If the dust quantity is kept to a minimum, filter life can be expected between 1 and 5 years depending on the application and runtime.
Here are some general design velocities when using "CAPTURE" Hoods:
Mist: Capture Velocity 100 FPMTransport Velocity 2250 FPMMinimum Face Velocity 1766 FPM
Here are some general design velocities when using "ENCLOSING" Hoods:
Mist CNC:Minimum Face Velocity 75 FPMTransport Velocity 2250 FPM
