How to determine the required cartridge specifications and quantity?

The calculation is based on air volume and filtration velocity: 1) Confirm the collector's rated air volume; 2) Select a standard filtration velocity by dust type (0.8–1.2 m/min for regular dry dust, 0.6–0.8 m/min for fine dust); 3) Calculate total filtration area = total air volume ÷ filtration velocity; 4) Based on the area of a single cartridge, calculate the required quantity, reserving a 10–20% margin to avoid overload. Excessive filtration velocity leads to over-velocity operation and rapid cartridge clogging.
