Our oil-less rocking piston vacuum pumps and air compressors offer superior performance by combining the best features of diaphragm and piston compressors into a compact unit. These devices are engineered to deliver clean, oil-free air, making them perfect for environments where contamination must be avoided, such as hospitals, laboratories, and the food industry.
Available in multiple configurations including single, twin, miniature, and tank-mounted styles, these pumps provide versatility for a wide range of applications. With options for dual frequency, shaded pole, and permanent split capacitor electric motors, they are compatible with North American, European, and global power supplies. Additional accessories and DC models in brush and brushless types enhance their adaptability.
The robust design ensures long-term reliability, featuring a bonded piston rod and bearing assembly that prevents misalignment, slipping, or loosening. This construction minimizes maintenance needs while maximizing operational efficiency. Performance metrics include air flow capabilities from 3.4 LPM to 5.5 CFM, pressure up to 175 psi, and vacuum capabilities reaching 29 inHg, with horsepower ranging from 1/20 to 1/2 HP.
These pumps are widely used in medical applications such as surgical aspiration equipment, oxygen concentrators, and ventilation systems. In dental settings, they support portable equipment and vacuum ovens. Laboratories benefit from their use in vacuum filtering, test equipment, and fluid analysis. Other applications include diving air systems, vacuum food sealers, tire inflation, automotive suspensions, and more.
