Fabco-Air | Series BA and Series BP

Add the Control, Rigidity and Power of Hydraulics to an Air-Powered Machine

When your air-powered machine requires the rigidity and smooth control of hydraulics, Multi-Power Boosters are an optimal choice. These convenient, compact and low-cost units use shop air to raise the pressure of another gas or liquid in a variety of applications. When relatively small volumes of high-pressure fluid are needed intermittently, boosters excel versus continuously running hydraulic systems. They’re also ideal when high pressure must be maintained for prolonged times. After the booster strokes, there is no further energy input required and no heat buildup.

Boosters operate with up to 150 psi shop air or other compatible gas, and the output can be oil, liquid, air or gas. Using multiple pistons to compress the media in the output end, the booster raises the output pressure to 500 psi max. With the right combination of bore size, stroke, power factor and regulating input air pressure, you can achieve and maintain precise output pressure and volume.

Multi-Power Boosters are available in two versions:

Series BA. This series is suitable for systems in which the input to the boosters will be gravity-fed fluid or atmospheric pressure gas. The booster requires a four-way valve for operation.

Series BP. This series can be used on systems in which the input to the booster will be pressurized fluid or gas. The unit requires a three-way air valve for operation.

Technical Advantages

Boosters give the work cylinder the rigid, smooth, controlled motion of hydraulics without the costly hydraulic system.
Boosters lower energy costs by holding pressure indefinitely without losing energy.
In most applications, boosters can be mounted directly on the machine for space savings.
Most of the control valves are installed in the low-pressure circuit, where lower-cost components are used instead of expensive hydraulics.
The boosters have hard anodized aluminum inner and outer diameter construction to resist corrosion.
Because boosters can be completely air operated, they can be used safely in potentially hazardous environments.
Air-to-air boosters have no oil or liquid to contaminate their surroundings.
Buna-N O-rings are internally pre-lubed.
They can be adapted and controlled to perform in a wide variety of applications including those without cylinders that still need a small volume of high-pressure media.
