Description The new portable Silencer air blower by Air Supply has taken a leap in quiet performance. Many competitive blowers use filter foam to reduce noise, but foam may clog over time causing starvation and overheating. Included with each portable pool air blower is a durable spring check valve. This is far more effective than flapper valves at stopping motor damage, which means longer life and reduced service calls. A pool air blower silencer is a device that reduces noise and vibration from a pool blower. Silencers are often placed at the blower’s inlet and discharge for pressure applications, and on the discharge only for vacuum applications 1HP; 240V Blower   Rubber motor mount suppresses noise while enabling the motor to vibrate without interference Enduring spring check valve has been included in place of the unreliable flapper valves The risk of clogging due to the aging of foam has been eliminated Show More Show Less
