BOFA’s DustPRO 50 extraction unit has been developed to help with the filtration of swarf and small particulates during processes such as routing, mechanical engraving, grinding and turning.One of the main problems with other router extraction relates to the type of pump used. Most have brushed motors which are noisy in operation and frequently burn out. The pump used in the DustPRO 50 is brushless and designed for continuous running for long periods of time before servicing.
