Back Blow Air Nozzle For Cleaning Tiny Inside Diameters

EXAIR's new Model 1004SS, M4 NPT Back Blow Air Nozzle has been designed to deliver the smallest, most effective airflow for blowing debris and liquids from small pipe or hose inside diameters, channel, bores, holes, internal threads and other internal part features. An array of holes provide a forceful 360 degree airflow to clear out coolant, chips and light oils from machining processes. This nozzle prevents blowing chips further into a part, tube or pipe and eliminates any safety hazard created by blowing debris out the far end of a pipe or tube.

The Model 1004SS Back Blow Air Nozzle thread is M4 x 0.5 and manufactured with a small profile. This nozzle will fit inside openings as small as 1/4″ (6.3mm) and is effective on diameters up to 1″ (25.4mm). It is constructed of type 316 stainless steel to provide durability and superior resistance to corrosion. Installation is simplified and a secure fit is assured with flats milled on the body. Since airflow is directed back toward the operator, personal protective equipment is recommended. Chip shields to protect the operator from the exiting debris are available. Extension pipes are stocked in 6″, 12″, 24″ and 36″ to provide necessary reach for cleaning out longer tube and pipe diameters.

Sound level is low at 80 dBA and meets OSHA noise requirement 29 CFR 1910.95(a), as well as being CE compliant.

T.J. Davies' Retention Knobs

Our retention knobs are manufactured above international standards or to machine builder specifications. Retention knobs are manufactured utilizing AMS-6274/AISI-8620 alloy steel drawn in the United States. Threads are single-pointed on our lathes while manufacturing all other retention knob features to ensure high concentricity. Our process ensures that our threads are balanced (lead in/lead out at 180 degrees.) Each retention knob is carburized (hardened) to 58-62HRC, and case depth is .020-.030. Core hardness 40HRC. Each retention knob is coated utilizing a hot black oxide coating to military specifications. Our retention knobs are 100% covered in black oxide to prevent rust. All retention knob surfaces (not just mating surfaces) have a precision finish of 32 RMA micro or better: ISO grade 6N. Each retention knob is magnetic particle tested and tested at 2.5 times the pulling force of the drawbar. Certifications are maintained for each step in the manufacturing process for traceability.
