Sullair Australia has released stainless steel portable compressors that provide long-life and peak performance in the harsh northern Australia climate. They have a stainless steel cabinet, which means they won't rust in the salty atmosphere on the coast or in the acidic environments often found at coal mines.
The first company to use the compressors is Weipa-based, Queensland contractor, N.Q. Blasting and Coating, which specialises in abrasive and protective coatings. NQ Blasting and Coating currently uses three 80kW stainless steel portable models, offering 177L/s free air delivery, and one 200kW model, offering 425L/s free air delivery. These are used primarily for the abrasive blasting and spray painting of large structures and surfaces at various outdoor locations.
The air must contain no moisture or impurities in the compressed air. They are fitted with an aftercooler to reduce the compressed air temperature to ambient, and in doing so, condense the moisture in the air for easy separation. The compressors achieve instrument air quality.
All-weather fluid (AWF) lubrication extends the life of the compressor. Sullair Australia's standard two-year air end warranty is extended to five years, or 10,000 hours, when AWF compressor fluid is used consistently. In colder or even snowy conditions, the portable's aftercooler function can be manually switched off to avoid freezing the compressor.
The compressor’s shutdown system and annunciation module (SSAM) can warn the operator if the temperature reaches a high or low alarm-level, the engine oil pressure is low or the engine is running under speed. They also use Caterpillar diesel engines, which come under a far-reaching support network.
