A Breakthrough in Filtration Technology
The Rotary Pleated Belt Filter (RPB) is a patented, revolutionary design that combines high capacity pleated membrane media with high efficiency suction cleaning. The result is a high efficiency self-cleaning filter offering more capacity for its size than any filter on the market. Unlike filters that rely on building a fiber mat to retain small dust particles, the RPB Filter does not. And unlike felt bag or cartridge filters, it doesn’t simply blow or pulse dust back into the air stream. And it doesn’t take up nearly as much space. For the first time, thorough automatic cleaning of agglomerated fibers and dust out of dense pleated high efficiency filter media is possible. The RPB is a member of Pneumafil's Everclean® line of modular preassembled air filtration and conditioning components.

Larger fibers collect on the outer edges of the pleats and smaller particles build up on the media surfaces between pleats. The clean air continues between the two sides of the cell into a plenum in back of the filter and then exits. Pressure drop across the media is constantly monitored by a dual setpoint Dwyer Photohelic gauge. When the high set point is reached a cell’s belt begins rotating around the pulleys, and a stationary suction plenum underneath the cell is activated. As the belt moves around the lower pulley, the pleats open up and air flow through the media is blocked, allowing the pleats to be easily vacuumed and pulsed clean.
 The patented media is a significant new design that is central to the RPB achieving its unique capabilities. The pleats are tightly spaced for filtration purposes and open up around the lower pulley for cleaning purposes. [ back to top ]
No tools are required for media changeouts. The filter cells are held in place with toggle clamps and the media is attached via velcro strips. The RPB Filter provides outstanding filtration performance for any air stream containing fiber and dust. To determine if the RPB Filter is suitable for your application, Pneumafil maintains a full scale test facility at our plant in Charlotte, NC. Contact your Pneumafil representative for a performance test on your dust.

The RPB Filter consists of a number of filter cells. Each cell is comprised
of an endless pleated media belt looped between two pulleys.
The RPB Filter is automatically controlled and normally does not require
operator intervention. In the unlikely event of a controller failure,
a manual override mode allows operation by hand.
