Feb 18, 2013· Air-to Cloth Ratio =Total volume of gas (or air) handled by the Bag filter [m3/min] /Total filtration area provided in the Bag Filter [m2] = [ m3/min-m2 = m/min, =>velocity unit; hence also called filtration velocity, and is actually the velocity at which the dust laden gases travel across the filter element ]The more critical the dust { fine ....
The dust is collected on the bag or fingers, and when the cake of dust is of appropriate thickness and structure, a pulse (or pulses) of compressed air is used to hit or shock the bag and knock the cake off This pulse may sometimes be accompanied by physical shaking Depending on the design, reverse airflows may also be incorporated...

• Filter Run Time: 115 lbs/125 lbs/hr = 92 hours The above calculations (depicted in Figure 2 on the next page) demonstrate how filter change-out time can be increased by over 14 times (92 vs 64 hours) by installing a five-around 3M High Flow filter housing While the larger 3M High Flow filter housing will be a higher capital...
Jul 21, 2016· First calculate the total cloth area of your collector by calculating the total filter area of each filter (bag diameter x 314 x length ÷ 144 [for number of inches in a square foot] = filter cloth area) and then multiply that figure by the total number of bags in the collector...
Jun 05, 2019· A filter bag calculation can also be made because filter bags are round If you know the diameter of the bag, multiply this diameter by 314 to get the circumference (Think back to high school math and the circumference of a circle ) Therefore, the circumference of the bags (diameter of the bag x 314) multiplied by the length of the bag ,...
