STATIC PRESSURE FIEQUJF{EMENTS FOR A DUST COLLECTION SYSTEM

Using STEPS 1 thru 4 and the "Static Pressure Requirement Chart" you can determine the static pressure required for your Dust Collector,

Step #1: Multiply the number of feet of Hose/Pipe times the appropriate inches rating,

Exampie; 40 feet of 4-inch diameter ribbed tubing x ,11 = 4.4 Total

Step #2: Multiply the fittings times the ratings and add them together,

Examp/e:Tw, o 90-degree Elbows (using 4qnch diameter Hose) = ,84 PLUS two 90-degree T-fittings = ,98 TotaJ = 1.82

Step #3: Add 2.5 for the Machine Hook-up and "Dirty Bag" factors (1,5 for Hook-ups + 1,0 for Dirty Bag),

Step #4: Total the above three calculations, This total should not exceed the maximum static

pressure for your Dust Collector,

Exaf_pie/4,4 (Total Step #1) x 1,82 (Total Step #2) + 2,5 (Total Step #3) = 8.72

For this example a Dust Collector with a Static Pressure rating of over 8.72 or higher is required. See Product Specifications on page 2 for your dust collector maximum static pressure.

NOTE: To determine if you have met the Static Pressure Requirement when using a Dust Collection System, identify the branch of the system with the highest static pressure requirement first, If you run your Dust Collection System with more than one blast gate open, add the static pressure from all branches that are open to determine the total static pressure requirements,
