What Timing Gears Are and Why Dry Oil-Free Machines Need Them In a rotary screw compressor, two helical rotors — one male and one female — intermesh to trap and compress gas as they rotate. For the machine to work correctly without rotor-to-rotor contact, the two...

Three Jobs, One Medium — Why Water Works Where Oil Cannot In any rotary screw compressor, the compression element faces three simultaneous engineering challenges: the rotors must be lubricated to prevent surface wear, the rotor clearances must be sealed to prevent...

The Root Problem: Where Dry Compression Wastes Energy Every conventional dry oil-free screw compressor has a fundamental thermodynamic problem built into its design. With no medium inside the compression chamber to absorb heat, all the work done on the gas during...

Why Purchase Price Is the Wrong Starting Point Most capital equipment purchases begin with a budget figure. Engineering specifies a compressor, procurement solicits quotes, finance approves the lowest number, and the equipment arrives. This process optimises for the...

Why Manufacturer Comparison Is Harder Than It Looks Every manufacturer of water-injected oil-free screw compressors publishes performance data that looks compelling at first glance. FAD figures are large, specific energy numbers are low, and certifications are...
