Alwitco Air Ejector Muffler 1/4" NPT A28

Featuring collimator inserts for concentrated air flow. Quickly and easily connected to any compressed air source. Concentrates the air stream in a narrow beam over a longer distance, delivering maximum force at a required point. Supplied as a complete unit with a cylindrical housing which can be directly attached to compressed air lines properly positioned for parts ejection or packaging requirements. Can be supplied with a standard plastic collimator insert or a special heat-resistant metal collimator insert (for use in locations with extremely high ambient temperatures). Separate collimator inserts also are available as a low-cost solution for applications where it is necessary to bore holes directly into a die and insert the collimator to provide exact air thrust.
