Pulse Jet Cleaning Systems

Most dust collector systems sold in the last 40 years are some type of pulse jet system. Typically present are pulse valves and solenoids located on the exterior of the system.

Utilizing compressed air to regenerate the filter media, the pressure utilized can range from 45 psi to 90 psi [3 to 7 bar]. These are typically classified into two systems:

High Pressure Pulse Jets and Low Pressure Pulse Jets

There are two significant differences between the two systems.

High Pressure uses low volume and high pressure to violently fracture the dust cake
Low Pressure uses low pressure and high volume to push the dust cake off the filter media

Pulse Jet Cleaning Systems are typically operated at Air-to-Cloth Ratios between 3.0 and 6.0 (acfm/sq ft/min)

Typically Nuisance Filtration operates at the 5-6 A/C range, while The key to operating performance is transferring the energy of the compressed air from the header to the point of filtration.

Keys to design include can velocity, compressed air consumption, Air-to-cloth ratio, pulse valve sizing.
