The ASV series of speed exhaust controller is available in two styles depending on size. The ASV120F/220F are elbow styles that look like a standard speed controller. The ASV310F~510 are a tee-type design with twice the flow capacity of a standard speed controller and also add flame resistance for use in welding applications.
The compact JASV speed exhaust controller is designed for decreased mounting height compared to the standard ASV. This enables installation in much smaller spaces than the equivalent ASV120F/220F. It features a push-lock adjustment design and can also be adjusted using a screwdriver (when unlocked).
