ZC Mechanical Rotary Reverse Air Flat Bag Dust Collector

The ZC Series Mechanical Rotary Reverse Air Flat Bag Dust Collector is a highly efficient, reliable, and structurally advanced dust collection system developed based on years of domestic engineering experience. With a proven track record across metallurgy, machinery, electric power, and other industries, the ZC series ensures low emission concentration, stable operation, and minimal maintenance.

Its cylindrical body ensures uniform stress distribution and high explosion resistance. By utilizing mechanical rotary arms and a high-pressure blower for reverse air cleaning, it overcomes the limitations of compressed air sources and achieves excellent dust removal efficiency, even in remote or cold areas.

Key Features

• Reverse air cleaning by rotary arm with fan-driven circulation
• Cylindrical shell design for better structural stability and explosion resistance
• Suitable for fine particulate collection in a variety of industries
• Independent control of cleaning cycle via differential pressure sensor or manual switch
• Filter bag life extension through energy-saving cleaning logic
• Capable of indoor or outdoor installation

Working Principle

1. Filtration Phase
   Dust-laden air enters tangentially into the upper space of the filtration chamber. Due to the cyclone effect, coarse particles are separated and fall directly into the hopper.
   Finer particles are captured by the outer surface of filter bags, and the purified air passes through the bags into the clean air plenum and is discharged by the fan.
2. Cleaning Phase
   As dust accumulates, differential pressure increases. When the upper threshold is reached, the reverse air fan starts (either automatically or manually), blowing compressed air through the rotating arm nozzle into the filter bags.
   This reverses the pressure inside the bags, causing them to flex and dislodge the dust into the hopper below.
   The rotary arm is divided into zones to perform sectional cleaning, enhancing cleaning efficiency while conserving energy.

Structural Components
