The invention is drawn to an apparatus for supplying fluid, such as air, under pressure to a fluid accommodating means such as an air mattress and automatically adjusting the fluid pressure. The apparatus has a coupling device which attaches the apparatus to the air mattress. A housing encloses a motor, an impeller, a two-way valve and a solenoid. The solenoid opens the two-way valve to allow inflation or deflation of the air mattress. The motor is reversible and the impeller is used to force fluid into or out of the mattress. A controller is used to inflate and deflate the mattress. The controller can be attached to the apparatus or it can be a remote control.
