BELFAB NBM-OP Series Modular Dust Collectors

BELFAB | NBM-OP SERIES MODULAR DUST COLLECTORS

Powerful, stand-alone dust system for indoor wood dust collection.

The Belfab NBM-OP Series Modular Dust Collectors are perfect for the collection of wood dust. The NBM-OP is an enclosure-less bag type filtration unit engineered as a compact and high efficiency system, offering a height of less than 11’. This dust collector is designed to operate as either a dedicated “stand alone”, or main dust collector within a woodworking facility.

The NBM open system design integrates BELFAB modular filter technology. This feature makes it possible to increase filtration surface cost effectively, with the introduction of additional filter modules.

This expandable filter module capability makes it possible to offer large filtration surfaces, capable of developing an air to cloth ratio better than 6:1. This feature makes it ideal for dust collection applications involving moderate to large dust volume in either coarse or fine material.

The BELFAB open dust collector modular series comes with our patented upgradable blower, that makes it possible to increase blower performance (on our standard blower) from a 5HP/2500CFM to a 20HP/ 6000 CFM MAX by simply replacing motor and impeller within the same fan housing.

The optional HUMMER 1800 RPM fan offers super quiet operation at up to 9000 CFM* (see note). In applications where there is a requirement for low sound level (under 84 db), BELFAB HUMMER series is available for application ranging from 10HP to 20HP 5000 CFM.

*up to 5000CFM for indoor installation. Above 5,000 CFM an outdoor set up is required (NFPA 664)
