HullaBalloo wants you to have everything you might need for your commercial inflatable business. This air pump comes with a pressure regulator. The Air pump has two outlet tubes. One is used for inflation of the product and once fully inflated, you can put the tube to the 2nd outlet area, and this one regulates the inflatable pressure. If the pressure of the product goes down, the air pump turns on and inflates the unit and turns back off, consistently keeping the right pressure of the product. This Air Pump with Pressure Regulator is excellent for products like our Inflatable Snow Globe. HullaBalloo Sales is here for you and offers the best products, at the best prices.
