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 (e.g. Grinding):Capture Velocity 500 FPMTransport Velocity 4000 FPMMinimum Face Velocity 4000 FPM
Gas (e.g. V.O.C.'s):Capture Velocity 50 FPMTransport Velocity 2000 FPMMinimum Face Velocity 785 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:
Smoke (e.g.Welding):Capture Velocity 100 FPMTransport Velocity 3000 FPMMinimum Face Velocity 2355 FPM

Ambient Air Cleaners-Dust Fume Vapor
|
|
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 contaminantes 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?
Information required to estimate the annual filter costs for a welding application:
1. Brand of Wire
2. Diameter of Wire
3. Type of Wire
4. Lbs of Wire per year
5. Condition of part being welded(minimal,low,medium or heavy oil content...)
6. Metals being welded
Here are some general design velocities when using "RECEIVING" Hoods:
Ambient Air Cleaner:
Minimum Face Velocity 250 FPM
Transport Velocity 250 FPM

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): Capture Velocity 100 FPMTransport Velocity 3000 FPMMinimun Face Velocity 2355 FPM
Dust (e.g. Grinding):Capture Velocity 500 FPMTransport Velocity 4000 FPMMinimun Face Velocity 4000 FPM
Gas (e.g. V.O.C.'s):Capture Velocity 50 FPMTransport Velocity 2000 FPMMinimun Face Velocity 785 FPM
Mist:Capture Velocity 100 FPMTransport Velocity 2250 FPMMinimum Face Velocity 1766 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
