Air Pump Company was founded in 1970 to sell compressed air related engineered products. They have evolved into the only supplier that specializes in Air Operated Pumps and Accessories. In 1973, Air Pump Company introduced the first version of their floatless level control from their own manufacturing division. Many new products later, they still craft each engineered control from the best materials available and insist on testing each unit before it leaves their Swartz Creek facility. Their controls are built to last for years in difficult industrial applications, and have been described as "Bulletproof".
