The RF collector works so well that many competitors strive to copy its award winning design, but no one has been able to duplicate the RF’s performance.
An involute scroll inlet puts dust into a cyclonic spin allowing for heavier particles to fall into the hopper, thus eliminating the need for a cyclone precleaner (for some applications with abrasive dusts, the optional high body inlet may be preferred). The remaining dust has then collected on oval shaped filter bags that provide greater snap during pulsing resulting in better bag cleaning. Rather than using expensive compressed air, the RF comes complete with a pump that provides a medium pressure/high volume pulse of air to a rotating cleaning arm timed to clean non-adjacent bag filters, thus reducing dust re-entrainment.
Even Airflow Distribution
To prevent bag filter wear and abrasion that can occur in other collectors, the RF baghouse collector comes standard with our proprietary Even-Air™ Flow Straightener or high body inlet. Designed using sophisticated FLUENT®* computer airflow analysis, the RF provides the most uniform airflow possible resulting in reduced bag abrasion, longer filter bag life and lower maintenance costs.

Benefits of the Oval-Shaped Bag
Oval shaped bag filters provide better snap during cleaning as compared to round bags— allowing the dust to be more easily knocked off the bags. This results in lower pressure drop and longer bag filter life.

Oval shaped bag filters increase the amount of bag material that can fit in a given area, thus increasing collector capacity. |
