PET MASTER SERIES

PET MASTER SERIES


 50-300 HP   580 psi  127-812 cfm


Oil-Free, Water Cooled, Fixed/Variable Speed

Reciprocating Air Compressors

We provide reliable and high-performance air solutions for the PET bottling, food and beverage industries requiring high compression.

 Advantages 

• Compact structure, easy to install and assemble.

• Takes up less room than other products in its class, providing maximum oil-free air capacity in minimum space.

• Wear due to friction is minimized. This positively affects maintenance times and costs.

• Stainless water separator increases corrosion resistance.

• Soft start prolongs component life.


 General Features 

• Reciprocating compressor providing 100% oil-free industrial air

• Electric motor protection to prevent overload

• Water-cooled design for high energy efficiency and ability to work in severe conditions

• Energy-saving Load/Unload System for efficient operation

• Integrated electrical system for user-friendly operation

 Electric Motor

• IE3 efficiency-class electric motors

• Special loadless start system and automatic discharge system for loadless start

• Long life with low RPM thanks to 6 pole feature


 Compressor Block

• Water jacketed cast iron cylinders and bottom heads

• Specially designed high-speed stainless steel concentric valves

• High-strength cast iron oil sumps

• Dynamically balanced high-strength forged steel crankshaft and cast iron

• Special aluminium alloy pistons and forged steel connecting rods


  Cooling System

• The intercoolers and aftercoolers use stainless steel pipes for more efficient heat transfer and better corrosion resistance.

• The coolers are designed to pass air through the pipe and water through the body wall.

• The compact design of the pipe-type coolers ensures easy maintenance and very efficient cooling
