Starting a Compressor in Cold Conditions

by OPPAIR Team on 26-10-19

Cold starts stress oil, seals and drains more than hot running does. A few checks before the first start of the season prevent most winter failures.

Sizing an Air Receiver for Peak Demand

by OPPAIR Team on 26-10-19

A receiver does not make air; it buys time. Sized correctly it stops the compressor chasing every short spike, and it protects pressure at the tool.

Screw Versus Piston Compressors for High-Pressure Work

by OPPAIR Team on 26-10-19

Above the general workshop band the choice narrows: screw machines for continuous flow, piston machines for very high ratios and intermittent duty.

Oil-Free Versus Oil-Injected Compressors: When Each Is Required

by OPPAIR Team on 26-10-19

Oil-free is a statement about the compression chamber, not about the air at your tool. Filtration decides what actually reaches the process.

ISO 8573-1 Air Quality Classes Explained

by OPPAIR Team on 26-10-19

Compressed air quality is quoted as three numbers, not one. Reading them correctly decides whether the dryer and filters you have bought can actually meet the specification.

How to Read an Air Compressor Datasheet: Flow, Pressure and Power

by OPPAIR Team on 26-10-19

Three numbers decide most of a compressor purchase - free air delivery, working pressure and motor power - and they are routinely quoted in ways that are not comparable.

Condensate Management: Drains, Separators and Disposal

by OPPAIR Team on 26-10-19

Every compressor produces water. Where it goes decides whether the system corrodes, whether the dryer works, and whether the oil in it ends up in the drain.

Compressed Air for Fiber Laser Cutting: Pressure, Purity and Cost

by OPPAIR Team on 26-10-19

Assist air replaces nitrogen in many laser shops. What the laser needs is a narrow pressure band, dry air and no oil - and a compressor sized for continuous duty.
