Kaeser's Airtower compressor packages combine a rotary screw air compressor, storage tank, and dryer in one. Designed for light industrial and commercial workshops, Airtowers are available in 4, 5, and 7 ½ hp models and deliver up to 28 cfm at pressures from 80-217 psig. The industrial-grade Sigma Profile airend provides more air with far less noise and vibration than piston compressors. The vertical receiver tank with automatic drain and integral refrigerated dryer delivers clean air. The one-piece cover is easily removed for full access to maintenance items.
