FAQs

Duty cycle. A piston machine compresses in strokes and needs rest time; a rotary screw element compresses continuously, running cooler and quieter under sustained load. If air demand is steady through the shift — bodyshop lines, production tools, multiple bays — screw is the right technology. Intermittent demand is piston territory.

From measured or summed continuous demand, not horsepower. Add the CFM of everything that runs simultaneously, then choose a machine whose free air delivery comfortably exceeds it — screw compressors are happiest running loaded, and gross oversizing causes inefficient start-stop cycling. The delivery figure at rated pressure is on every product page.

If the air feeds paint, plasma cutting, control valves or quality-sensitive tools, yes — compressed air carries moisture that condenses downstream. Packages with integrated refrigerant dryers and receiver tanks are listed in the range, which keeps the installation to a single footprint.

Service by running hours: oil, oil-separator element, air filter and oil filter on the manufacturer's schedule, plus belt or coupling checks. It's routine and predictable — the machines are built for it — but skipping separator changes is the classic cause of oil carry-over and early element wear.
