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
