Today’s users expect maximum availability and efficiency from their compressors, regardless of size. It will therefore come as no surprise that KAESER’s ASK series rotary screw compressors go far beyond simply meeting these key expectations. Not only do they deliver more compressed air for less energy, but they also combine ease of use and maintenance-friendliness with exceptional versatility and environmentally responsible design.
