Welding Bays
Guaranteed Solutions!

In the typical welding bay, you often have overhead cranes, forklifts, jib cranes and a variety of material handling equipment that make it a challenge for many welding fume extractors to capture hazardous welding smoke and fumes. Industrial Maid has several tested and proven solutions for welding air filtration. Let us show you how our T-Series packaged welding fume extractors and welding air filtration systems are quickly becoming the industry standard for controlling smoke and fumes ininset welding bays large fabrication shops across the U.S. Our energy efficient welding ventilation hoods provide a push-pull air pattern to keep the air quality in check, protect your welders, protect your assets and keep energy costs in control. Our variable frequency control packages help lower energy consumption, increase filter service life and extend the life of the electrical motors.

Variable Frequency Drive B Series welding bays


The Delta B series variable frequency drives can help you save energy dollars, prolong the motor life and extend the filter service life. These electrical controls will soft start the industrial air cleaners and can then ramp up as needed to provide the airflow rates to match the specific application. Our engineers can factory program the drives to provide automated performance on your industrial packaged air cleaners. You can also request complete control panels with running lights and on/off switches.

Step 1
Determine the AER – Air Exchange Rate from Table 1 that best fits your application needs.

Step 2
Determine the total cubic feet of your plant work area
Total cubic feet = L x W x H (maximum height 20’)

L = length of your workspace (feet)
W = width of your workspace (feet)
H = height of your ceiling in the workspace (feet)

Note - we use dimensions only to 20 feet as smoke, dust and fumes will stratify well below this height. Example: 24 ft ceiling height—20 ft.

Step 3
Divide the total cubic feet by the AER determined in Step 1.

Step 4
Divide this total by the CFM of the unit you prefer to use.
T-3000 is 3000 CFM
T-3500 is 3500 CFM
T-4500 is 4500 CFM
T-6000 is 6000 CFM
T-7500 is 7500 CFM

Workspace is 100’ long X 60’ wide X 18’ tall
Total cubic feet is: 100 X 60 X 18 = 108,000 cubic feet

Welding application
Medium use 5 as the AER (air exchange rate)
(from Table 1) 108,000/ 5 = 21,600

Assume using a T-3500 (3500 CFM unit)
21,600/3500 = 6.17 or 6 units to handle the application.

Step 5
Determine best location or placement for the welding filtration systems.

Our qualified staff is always available to help you determine CFM requirement, placement and then final selection of the units that will provide you the best "cost of ownership" in regards to electrical consumption and filter service costs. Contact Sales @ (877) 624-3247
