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.
