Baghouse Design Calculations: Dust Collector Calculator

Air to Cloth Ratio

Enter the ACFM of Air ÷ Sq. Ft. of Cloth

Then Click on Calculate To Find the Air to Cloth Ratio

ACFM ÷ Sq. Ft of Cloth

Air to Cloth Ratio = to 1

Enter ACFM of Air ÷ ( Side L (in.) × Side w (in.))

144 sq. in / sq. ft.

Then Click on Calculate To Find the Can Velocity

ACFM ÷ ( Side L × Side W )

144 sq. in / sq. ft.

Can Velocity = FPM

Enter (Bag Diameter × π × Length of Cages × # of Bags)

144 sq. in / sq. ft.

Then Click on Calculate To Find the Cloth Area

Bag Diameter × π × Length of Cage × # of Bags

144 sq. in / sq. ft.

Cloth Area = Sq. Ft.

Air to Cloth Ratio to 1 × ACFM

Sq. Ft of Cloth =

Air to Cloth Ratio to 1 × Sq. Ft of Cloth

ACFM =

Enter ACFM of Air ÷ ( Side L (in.) × Side w (in.)) - (Bag Dia.÷2)² × π × # of Bags

144 sq. in / sq. ft. 144 sq. in / sq. ft.

Then Click on Calculate To Find the Interstitial Velocity

ACFM ÷ (Side L × Side W ) - Bag Dia. × π × # of Bags

144 sq. in / sq. ft. 144 sq. in / sq. ft.

Interstitial Velocity = FPM
