ABSTRACT:
A blower includes a base having a transverse passage for receiving a motor therein and a fan device driven by the motor extends from a hole in an end of the base. A casing including an outlet is connected to the base and mounted to the fan device. An anti-back device is engaged in the outlet and includes a frame to which a plate is pivotably connected. The plate is opened by the air sent via the fan device in one direction and seals the outlet when air goes in opposite direction.
