Air Compressor Guides
From selecting the right compressor type to diagnosing pressure loss — technical guides written for maintenance engineers, not marketing teams.
Rotary screw compressors dominate industrial plants above 15 kW because they deliver continuous, pulse-free air at 7–13 bar with low specific power (typically 6.5–8.5 kW per 100 L/min). Add a refrigerated air dryer and correctly sized receiver tank to protect downstream tools and processes.
Compressor Types
Rotary Screw Compressor Guide
How twin-screw technology works, oil-flooded vs oil-free, typical efficiencies, and when to choose rotary screw over piston.
Reciprocating vs Rotary Screw
Side-by-side comparison: capital cost, duty cycle, maintenance interval, noise, and air quality for each type.
Variable Speed Drive (VSD) Compressors
How VSD cuts energy up to 35% at part-load, payback calculations, and when a fixed-speed machine is still the right choice.
