Exair (www.exair.com) has developed a new, heavy duty safety air gun and an adjustable, flat air nozzle.
The flat nozzle is designed to be used for ejecting heavy parts and slugs, chip removal, part cleaning, drying, liquid blowoff and cooling applications.
The 2 in., High Power Super Air Nozzle produces a flat, 2 in. (51mm) wide airstream with a blowing force of 2.2 lbs when mounted 12 in. from the target. The company said the nozzle’s adjustable force is more than three times that of ordinary air nozzles.
It uses Exair’s patented technology to maximize entrained airflow while reducing noise levels. A precise amount of air is released through the .025 in. (0.64mm) air gap opening that is set with a stainless steel shim positioned between the body and removable cap. The airstream pulls in surrounding room air to produce a wide, forceful stream of high velocity, laminar airflow. Air consumption is 37 SCFM at 80 PSIG, and produces an 83 dBA sound level that is below the limits of the OSHA maximum allowable noise exposure standard.
Exair said the force and flow of the nozzle can be adjusted by installing different shim thicknesses.
Separately, Exair’s heavy duty, safety gun is designed to remove chips, dust and other contaminants from products, machinery and work surfaces.
It has an ergonomic, composite rubber grip and wide curved trigger to make it comfortable for hours of use without fatigue. It has a durable cast aluminum body that is ideal for rugged, industrial environments.
The heavy duty safety air gun uses a 3/8 NPT compressed air inlet to increase the airflow available to its super air nozzle, resulting in higher force and flow than ordinary air guns. The company said it engineers air exhausts from its Super Air Nozzles to deliver the highest force at the lowest air consumption.
A variety of Heavy Duty Safety Air Gun models use different engineered Super Air Nozzles, to give users a choice of flow, air pattern and force that ranges from 13 oz. to 3.3 lbs.
Applications include parts cleaning, chip removal, part drying, part ejection, and liquid blowoff. Aluminum extension pipes to provide “reach” for areas not easily accessible are available in lengths up to 72”.
