ASCO product SE100HB is constructed with a unique expansion chamber, completely free of obstruction, exhaust air flows softly to atmosphere free of noise, oil fog, and contaminates, providing a clean comfortable productive work environment. Constructed entirely of corrosion resistant material for long life and maintenance-free performance, units are provided with a hex head, making it easy to attach to exhaust ports. They should be mounted in a protective position, free from excessive vibrations. High Pressure Mufflers SEHP are engineered for silencing high pressure exhaust noise; models available also for much higher air pressures. Units are made to meet specific requirements.
