Air Pump Controller

Hi, I'm trying to inflate air battlers that will lift an average person of 170 lbs. I was wondering does anyone know of an air pump, that I could control,

on/off air, and the rate or pressure of air, so that I can control the rate of which the air is entering the air blatter. Or how would I install arduino into a regular pump to control the air going out?

It is not easy to vary the flow rate of the air continuously. Better off to set the output pressure via a regulator and time the flow.

Use a common air compressor from a hardware store as these have pressure switch to stop the motor at a max pressure. Fit a pressure regulator to the output and use an electrically controlled air valve. These usually require 24v to turn on.
