Details

This dust collector uses BELFAB’s patented modular technology, allowing to add-on filtration modules when the volume of air to be filtered increases, or to optimize the filtration ratio cost-effectively.

The NBM can operate with BELFAB’S upgradeable fans, a patented technology. These fans can be modified to increase the airflow from 2 HP / 1000 CFM up to twin 20 HP / 12 000 CFM fans. This is accomplished by replacing the inlet, fan wheel and motor of the fan.

Different dust disposal options are available, varying from the simple steel drum, the easy to handle plastic tilt truck to the high production pneumatic dust transfer system.
