FAQ
Q Oil-flooded or oil-free?
A
Oil-flooded: 85-90% efficiency, low maintenance, 10+ year life. Oil-free: food/pharma/electronics, no contamination, but 75-80% efficiency and 2-3x cost.
Q Compressed air drying?
A
Refrigerated (+3°C dewpoint) for general industry; adsorption (-40°C) for instrumentation; membrane (small, low cost) for labs.
Q Energy savings?
A
VSD drives save 20-35% at part-load; centralized supply replaces scattered units; leak detection on piping. Atlas Copco GA VSDs is the benchmark.
