What is Baghouse Dust Collector?

Baghouse Dust Collector equipped with compressed air cleaning suitable to filter and separate up medium, fine and impalpable dusts with high filtering efficiency and a continuous perfect filter cleaning system.

Baghouses are industrial dust collectors that use anywhere from 6 to 900 felt bags to filter dusty air produced by various manufacturing and processing applications. In most baghouses, a large fan pulls dusty air into the collector where the dust collects on the exterior of the felt bags and cleaned air then exits the collector. NAPCEN offers a complete line of dependable, rugged baghouse dust collectors to keep your operation running smoothly.

Operating Principle

Baghouse Dust Collector is a highly efficient, self-maintaining filter for dusts with fully automatic cleaning by compressed air injection. The unit is manufactured with individual, reinforced, painted steel panels which make for extremely robust construction. The design includes an upper chamber which houses the compressed air cleaning system, the center section which includes the required filtering sleeves and a lower section with the supporting legs, hopper and polluted air inlet. It is working in depressure according to following process.

The contaminated air enter from hopper inlet by the strong speed decrease, larger particles drop into the wheeled waste bin. Also available a version with pre-chamber including a system to make the high concentrated dusts falling down, the inlet will be not in the hopper in this case but directly in the pre-chamber. Alternatively the hopper can be equipped with rotary valve and worm conveyor. The cleaning guaranteed by the reverse jet system with compressed air controlled by the depressure cyclic programmer that gives impulse to the solenoid valves cleaning a row of filtering sleeves each time, obtaining in this way a quite constant loss of charges level and constant air flow.

Dusty air is pushed, under the filtering sleeves , by the inlet situated in the hopper. Dust, contained in the sucked air, owing to the considerable speed decrease, will fall in collecting bin. Then dust crossing filtering media from the outside to the inside will deposit impurities giving back the air perfectly cleaned. During operation filter is always in perfect efficiency to the cyclical counter-washing Cleaning System.

A Compressed air stored in the provided tank is suddenly pushed inside the sleeves, creating a violent counter current shaking wave , which takes out and make falling particles , deposited on the sleeves. This cyclical programmed by an Electronic Control , will be injected by a range of nozzles inside their Venturi-Tubes connected to filtering sleeves . These tubes can collect the surrounding area air and enlarge it compared to the received Jet.


The filter made in press-bended metal sheet panels. Filtering sleeves are made of high quality fabric studied to solve filtering problems with high efficiency and long life resistance and performance. The sleeves are fitted on metal cage galvanised or painted to increase its resistance and life time. Media cleaning System is composed by a cyclic programmer with pause and cleaning time governor, control light, compressed air collecting tank, die-cast electrovalves with electric consent pilot, injectors and Venturitubes in plastic material, or on demand, totally made of metal. The filter is complete with supporting legs, electrical connections between valves and programmer, inspection door (on demand) and hook up flanges.

  • The total system is modular design. Each modular can be shipped in a standard container, which greatly saves the shipping freight.
  • Most components pre-installed in factory to minimize installation on site. No welding work is required on site, which allows quickest erection of system.
  • Low resistance high efficient needle felt bags ensure the baghouse system work under lowest energy consumption.
  • Advanced pulse clean technology makes the compressed air consumption to a minimum, effectively reduces the operation cost.
  • Special deflector chamber on the inlet entry effectively knock down the large particles to hopper directly. Protecting the bags and increasing their lives.
  • Each modular is available in different height to accommodate different airflow. Inlet and outlet are special designed to achieve optimal airflow.
  • Minimum maintenance and tool-free maintenance for filter bags & cages. Easy access doors on top of dust collectors.
  • Specially designed pulse valve chamber to protect the valves and control the pulse cleaning noise.
