How many Air Filtration units do you need for your space: A Helpful Guide
First Step in Choosing an Air Purifiers
Determining Air Exchange Rate (AER) and CFM Calculation
Applications and Recommended Air Exchange Rates:
- Welding: 4-6 minutes
- Grinding: 6 minutes
- Plasma Cutting collection over a wet table: 6-8 minutes
- Diesel Smoke: 8 minutes
- Foundry: 6-8 minutes
- Plastic Smoke: 8-10 minutes
- Wood Working: 8-10 minutes
- General Ambient Air: 10 minutes
Step 1: Determine Air Exchange Rate ( AER)
- Choose the appropriate Air Exchange Rate (AER) from the provided table above based on your application.
Step 2: Calculate Total Cubic Feet of your space
- Total Cubic Feet = L x W x H (maximum height 20’)
- Where:
- L = length of workspace (feet)
- W = width of workspace (feet)
- H = height of ceiling in the workspace (feet)
Step 3: Calculate CFM
- CFM = Total Cubic Feet / Air Exchange Rate (AER)
Example:
- Workspace dimensions: 100’ long x 60’ wide x 18’ tall
- Total Cubic Feet: 100 x 60 x 18 = 108,000 cubic feet
- AER for Welding (medium use): 5
- CFM = 108,000 / 5 = 21,600 CFM
Second Step in Choosing a Commercial Air Purifiers
Consideration of Installation and Mobility
- Evaluate ease of installation and mobility.
- Placement is crucial for optimal performance.
- Consider existing HVAC systems, cranes, or fans in place.
- Anticipate future changes, growth, and possible relocation.
Third Step in Choosing an Air Purifiers
Efficiency Considerations
- Prioritize efficiency to control running and maintenance costs.
- Look for lower horsepower ratings.
- Choose a system that is self-sustaining, recirculating air within the shop.
