A 39-second field guide covering the five daily start-up checks, the six service intervals and the warm-up routine that keep OPPAIR diesel portable and towable air compressors running through drilling and construction duty.

READ MOREOPPAIR skid-mounted laser special screw air compressors deliver 16-20 bar bone-dry air directly to the cutting head, replacing liquid nitrogen and cutting auxiliary gas costs by 60-80% for 12 kW to 30 kW fiber laser shops.
READ MOREWhen one process needs more pressure than the header, a booster is usually cheaper than raising the whole system.
READ MOREA chiller is often bought to fix a temperature problem that starts somewhere else. What to check before specifying one.
READ MOREBlowing is a continuous, high pressure, high purity duty. The compressor, dryer and storage have to be specified together.
READ MOREDowntime is decided by what is not on the shelf. A short, sensible spares list beats a warehouse of parts you never use.
READ MORERefrigerated or adsorption, the dryer has to be sized at the real inlet conditions - not at the compressor's nominal flow.
READ MORESingle phase power limits motor size, so the package has to make the most of what a workshop supply can deliver.
READ MOREAn economy PM VSD package targets small and medium workshops. The savings are real, but only if the machine is sized to the actual demand.
READ MORESame principle as nitrogen generation, different sieve and different safety rules. Where on-site oxygen makes sense and what the installation has to respect.
READ MOREPurity and flow pull in opposite directions. Understanding that curve is most of the selection decision.
READ MORESite compressors are chosen by pressure band, towing arrangement and duty cycle more than by brand. What the catalogue covers and what to ask before renting or buying.
READ MOREThe extra stage in a 5-in-1 package is usually filtration or drying. For laser work that is the stage that decides whether the optics survive.
READ MOREA skid package moves work from the site to the factory. What the site still has to provide is a base, power, cooling air and a drain.
READ MOREIn an oil-cooled machine the oil is a working fluid, not just a lubricant. Treating it that way is what keeps temperatures and efficiency stable.
READ MOREAbove the standard band, splitting compression across two rotors is what keeps temperature and efficiency in a workable range.
READ MORELaser shops buy a pressure band and an air quality class. The 4-in-1 package is how those two requirements get delivered as one system.
READ MOREOil-free compression is a specification decision before it is a machine decision. Here is how the family is arranged and what it demands in service.
READ MOREVariable speed gets the attention, but a fixed speed machine sized correctly is still the cheapest way to make air at a steady full load.
READ MOREPermanent magnet variable speed machines are now the default for plants with varying demand. What to check before you specify one.
READ MOREIntegrated packages put compression, drying, storage and filtration on one frame. The value is in the interfaces that disappear.
READ MOREA fixed speed compressor is efficient at its design point and wasteful below it. Variable speed changes the shape of the curve, not the peak.
READ MORECold 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.
READ MOREA 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.
READ MOREAbove the general workshop band the choice narrows: screw machines for continuous flow, piston machines for very high ratios and intermittent duty.
READ MOREOil-free is a statement about the compression chamber, not about the air at your tool. Filtration decides what actually reaches the process.
READ MORECompressed 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.
READ MOREThree 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.
READ MOREEvery 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.
READ MOREAssist 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.
READ MORERaising header pressure to satisfy one machine costs money everywhere else. The right number is set by the most demanding tool, not by habit.
READ MOREDryers fail quietly. The air still flows, the pressure still holds, and the first sign is water at a tool or a failed inspection.
READ MOREA chiller in a compressed air system controls temperature rather than humidity, and its role changes depending on whether it serves the compressor, the dryer or the process.
READ MOREPET blowing needs compressed air in the 20 to 30 bar class, which is why two-stage machines rather than standard single-stage units are used for the duty.
READ MOREA skid package moves the assembly work from the site to the factory, which shortens commissioning but shifts the design decisions to the specification stage.
READ MOREOn-site nitrogen generation removes cylinder logistics and lets purity be matched to the process, but it only pays where demand is steady enough to use the capacity.
READ MOREA diesel mobile compressor removes the dependence on site power and fixed installation, at the cost of fuel, noise and a maintenance regime of its own.
READ MOREAir compressors and dryers are rated to an ambient limit of about 45 C, and a room that exceeds it loses capacity before anything actually breaks.
READ MORESizing a compressed air package means matching flow, pressure, dew point and storage to the real demand profile, not picking each component separately.
READ MOREA staged Q to P to S filter chain with QPS 015, 024, 035, 060 and 090 elements brings residual oil down to 0.001 mg/m3, the ISO 8573 Class 1 threshold.
READ MOREThe OFD range covers 1.5 to 25 m3/min with a 2 to 10 bar standard working pressure, a 2 to 10 degrees C pressure dew point and DN25 to DN80 connections.
READ MOREThe OAD desiccant range runs from OAD-1 to OAD-50, covering 1.2 to 55 m3/min with DN25 to DN100 connections and unit weights from about 105 kg to 2,000 kg.
