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.
