When an oil free air compressor fails, the cost is rarely just the part — it is the stopped production line behind it. CMN's water-lubricated single-screw machines are engineered so that oil free...

A water injected compressor is an oil-free machine that replaces oil with water as both the sealing medium and the coolant inside the compression chamber. CMN builds this concept on a single-screw pla...

The water loop is the heartUnlike dry-type units, a water-lubricated compressor has a closed water circuit. Keeping it clean is the main upkeep task.Maintenance checklist1. Water quality — use the sp...

PET blowing needs clean high-pressure airPET stretch blow molding uses pre-blow (≈ 8–12 bar) then final blow (≈ 25–40 bar, 40 bar ≈ 580 psi) to biaxially orient the preform. Oil in the air can fo...

Why speed control mattersCompressed air is one of industry’s largest energy users — the U.S. DOE estimates roughly 10 % of industrial electricity drives compressors, and ENERGY STAR notes electricit...

Defining “medium pressure” for screw compressorsIn industrial screw terminology, low pressure is roughly ≤ 0.5 MPa (5 bar); medium pressure spans about 0.8–1.5 MPa (8–15 bar) for general plant ai...

What “water-lubricated oil-free” actually meansIn a water-lubricated oil-free screw compressor, water (not oil) is the sealing, cooling and lubricating medium inside the compression chamber. Air nev...

Evaluating an industrial compressor should never be limited to its purchase price. For equipment that operates continuously in demanding environments, the real value of an oil injection screw compress...

Global procurement managers face complex logistical and engineering bottlenecks when updating a factory\'s compressed air infrastructure internationally. Beyond cross-border supply chains, ensuring com...

Polyethylene Terephthalate (PET) is the premier packaging choice for global beverage and pharmaceutical brands due to its lightweight properties, structural strength, and high clarity. However, produc...

A PET bottle compressor that supplies blowing air is, in effect, touching every bottle your plant produces. If that air carries oil, the defect rides straight to the shelf. This article explains why &...
