The BP6/BP10 is light enough for anyone to handle and the ergonomically-designed Velcro straps at the chest and hips result in a comfortable fit for virtually any sized operator. A special slide adjustment hooks the shoulder straps together for a higher range of motion. The on/off switch is at hip level and mounted on top for unparalleled ease of operation. The unique airflow design makes this unit quieter than most and the baffled exhaust goes out the back, away from the operator, for a higher level of comfort. Comes with an extraordinary Ultrastat[TM] 3-ply composite filter, treated with an antimicrobial agent that provides exceptional airflow, even when full, allowing for greater productivity. This exclusive bag is fitted with a durable plastic rim for an airtight seal around the top, and the seams are sonically welded (as opposed to glue). The result is higher dust retention, and a much longer filtration cycle.
