The New Silencer by Air Supply has taken a quantum leap in quiet performance. The unique
motor mount is the secret to our success. A thick rubber cup encases the fan while
allowing the motor to vibrate freely on a flexible rubber base. This combination
eliminates noise so well that virtually no foam is required. Many competitive blowers use
filter foam to reduce noise, but foam may clog over time causing starvation and
overheating.
Included with each Silencer is a durable spring check valve. This
is far more effective than flapper valves at stopping motor
damage, which means fewer service calls and more satisfaction..
