It makes the Sierra the toughest machine in the business.
Stainless steel is used for critical sealing components, as well as for the high pressure rotor set.
But the real key for the customer is the optimum long term compressor performance, through minimized coating wear and efficiency degradation. In short, this means more compressed air for the operating cost dollar. The Sierra's packaging features were designed for optimum customer benefit. The 115 o F ambient rating lessens the chance for nuisance shutdowns due to summer heat or dirty coolers. With Sierra, the choice is yours for an air or water-cooled package.
