Abstract
A dual function air pump has a compressor with an inlet connected to a first port and with a first outlet connected to a second port. The air to the compressor is directed by a first tube from the first port, such that a suction effect exists at the first port. The air pumped out of the compressor is directed to the second port by a second tube, such that an exhaust or blowing effect exists at the second port. A pressure gauge is connected by an auxiliary tube to the second tube. The compressor further has a second outlet connected to a control switch assembly by a third tube.
