Kaeser Air Filter s a high-precision intake element specifically engineered for Kaeser’s smaller to mid-range rotary screw compressors. It is designed to safeguard the Sigma Profile™ air-end by capturing atmospheric dust and abrasive contaminants before they can enter the compression chamber. This specific filter is renowned for its high-density pleated media, which provides a large surface area for filtration while maintaining a very low pressure drop—critical for the energy-efficient performance characteristic of Kaeser machines.
