SC Hydraulic Engineering AB Series Air Booster

SC Hydraulic Engineering AB-2, AB-4 & AB-7 Series Air Booster is a leading manufacturer and designer of an ever growing line of high pressure, air-driven liquid pumps, as well as air and gas boosters which are being used in a variety of industries and applications. Growing since 1953, we offer liquid pressures as high as 65,000 psig and can exceed 17,000 psig in gas pressures.

General Product Information

  • Economical
  • Requires No Lubrication
  • Compact And Lightweight
  • Single Acting, Single Stage
  • Ideal For Oem Applications
  • Pressures Up To 680-psi (Ab-7)
  • Air Operated – Does Not Require Electricity

The AB Series air booster is a compact, single-acting unit available in 1.7:1, 3.7:1 or 7:1 ratios. This booster is an inexpensive alternative for applications requiring 100-680 psi static holding pressures when low flow is acceptable.

The air drive and supply are the same so no extra plumbing is required and no electrical connections are needed. The compact and lightweight size, and ability to operate in any position, has broad appeal for in-plant, mobile machinery, and OEM applications. The units are pre-lubricated therefore air line lubrication is not required.


  • Engine air starter systems
  • Top off high pressure tires
  • Release spring actuated brakes
  • Increase maximum torque on small air tools
  • Top off and maintain pressure in die cushions
  • Increase marginal air pressure to valve actuators
  • Extra force for small air clamps, roll tensioners, assembly machines and air presses
