EXAIR’s new models 1004SS, 1006SS and 1008SS Back Blow Nozzle are engineered to clean inside of pipe, tube, hose or channel. An array of holes provide a forceful 360 degree airflow to clear out coolant, chips or debris created from machining processes. These nozzles prevent blowing chips further into a pipe or out the end of the pipe, which is a safety hazard. Since airflow is directed back toward the operator, personal protective like chips shields is recommended when in use. All Back Blow Nozzles are made of Type 316 Stainless Steel. These nozzles are also available on Safety Air Guns.
