The explosion protection devices in bag dust collectors operate on principles such as controlling the amount of compressed air entering the collector, reducing fan speed, preventing flame propagation, releasing pressure, and avoiding static electricity buildup.

The LCMD pulse jet fabric filter, also known as a long bag low-pressure pulse dust collector, operates at a working pressure of 0.15 to 0.2 MPa for normal pulse jet cleaning, in contrast to high-pressure systems that require 0.5 to 0.6 MPa.
