Abstract
An encased air blower (10) includes a motor and fan assembly (21) which is connected to the casing (11) of the air blower (10) by a combination mounting and sealing member (22). The unique mounting and sealing member (22) provides a positive seal between the suction (12) and pressure (13) sides of the air blower casing (11). The unique mounting and sealing member (22) further serves to acoustically isolate the motor and fan assembly (21) from the casing (11) and thereby significantly reduces the operational noise level of the air blower.
