Alfamatic Air-Oil Boosters – MF 122-123-162-163-164-203-204

How it is Composed and how it Works

Alfamatic air-oil booster series MF is a unit composed of a pneumatic cylinder and an high pressure chamber.
By feeding the pneumatic cylinder with shop compressed air, hydraulic pressures of up to 400 bar are obtained, depending on the models.
The high pressure generated in the hydraulic fluid is directly proportional to the pneumatic supply pressure.

  • It works without lubrication
  • Possibility to turn fluid connections around 360 degrees
