Product details
Quiet peripheral bypass vacuum motor, part 1921, built by Ametek in the 5.7 in. QBP frame and carrying the ACUSTEK quiet designation. A bypass motor routes its own cooling air separately from the working air stream, so the debris the machine picks up never passes across the armature.
Three fan stages give the motor its lift, and the ball-bearing build (B/B) suits equipment that runs long duty cycles rather than short household bursts.
