Brief overview of the ALTO air treatment units:-

    • ALTO regulators enable the pressure to be adjusted to suit usage. A membrane and spring ensure a constant outlet pressure corresponding to the chosen value.
    • They protect pneumatic tools from excess pressure and cut unnecessary energy consumption. Regulators are equipped with a progressive membrane. The pressure is set via a control valve.

Different Types of Pressure gauge connection:
  • 1/8" FBSP for ALTO 1, ALTO 2 and ALTO 3
  • 1/4" FBSP for ALTO 4
The filter-regulator module combines the fi lter and regulator functions in a single module.

    • ALTO oil mist lubricators protect your pneumatic tools by injecting a precisely dosed amount of fi ne lubricant into the filtered air. Lubrication reduces friction between moving parts, avoids seizure, protects against corrosion, and absorbs and evacuates heat energy.
    • The action of ALTO lubricators extends the service life and the efficiency of pneumatic tools.
    • The oil fl ow is adjusted via a cone-point set screw, thereby controlling the amount of lubricant diff used into the pipework. Recommended oil: ISO VG32 (part number LUB 3256).
    • The oil tank can be filled during use. The tank is attached via a locking bayonet fitting for the ALTO 2, ALTO 3 and ALTO 4 units. ALTO 1 units feature a threaded tank.

  • The ALTO range offers a wide range of flow rates. From 1/4" FNPT threads to units with 1" FNPT threads
  • (pneumatic tools, pneumatic cylinders, blowing, inflation, paintwork, etc.).
