NBM ENCLOSED MODULAR DUST COLLECTOR

The NBM dust collector is designed to filter volumes of air varying from 2500 CFM to 12000 CFM. This model is ideal for moderate to large dust volumes in either coarse (cutting dust) or fine (sanding dust) material. This dust collector is suitable for an outdoor installation.

MODULAR FILTER TECHNOLOGY

The NBM 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 application involving moderate to large dust volume in either coarse or fine material.

UPGRADABLE BLOWER

The BELFAB dust collector modular series comes with our standard patented upgradable blower, that makes it possible to increase blower performance by simply replacing the motor and impeller within the same fan housing. Our optional HUMMER 1800 RPM fan offers super quiet operation at up to 9000 CFM. In an application where a low sound level is required (under 84 db), BELFAB HUMMER series is available for application ranging from 10HP to 30HP (9000 CFM). The optional RSC blower series from Belfab is more performant and more efficient. The RSC fan wheel is specially designed for systems transporting moderated loads of dust, powder and particles.

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