PBF Filters :
System Design
The PBF is the heart of a system that provides efficient removal of fibrous dust from plant air streams. A MikroPul Pleated Belt Filter System consists of the following:
MikroPul can engineer, supply, and install the complete system, including airlocks and ductwork, from the plant air inlets to the clean air exhaust.  Stripped Dust
An inner cylinder induces cyclonic flow, causing larger particles to separate from the air stream and fall into the hopper. The remaining fine particles collect on the filter bags, which are cleaned through periodical back-pulses. Modular Component System The Pleated Belt Filter is one member of MikroPul’s modular component line of preassembled and prewired air filtration units. Modules can be bolted directly to other components as needed to suit your application. Each module is skidded to allow easy relocation as needs change. The illustration shows how these modules can be assembled to form a complete, very compact filtration system. 
In the example shown, the system includes:
The entire system is only 7.3 m (24 ft ) in length. As shown, this system can filter up to 73,600 m3/hr (43,300 CFM) and can be configured to filter up to 102,000 m3/hr (60,000 CFM). MikroPul can also provide other modules for air conditioning, including:

Collector
Dust stripped from the PBF’s media is carried away in a relatively
low volume air stream. Because of the lower air quantity, the dust can
be efficiently collected in a specially designed pulse-jet collector.
As shown in the drawing, dust laden air enters the unit through a tangential
inlet.
