Coilhose Pneumatics 640S Safety Air Blow Gun 10 Scfm 1/4 Npt

Product Description

The COILHOSE PNEUMATICS 640S is a standard safety air blow gun designed for use in industrial and shop pneumatic systems. It accepts a 1/4 NPT inlet connection and features a brass nozzle with a zinc-finished body built for corrosion resistance and durability in demanding environments. The gun delivers up to 10 standard cubic feet per minute (SCFM) of airflow and produces a decibel rating of 84 to 87 dB during operation. It is rated for temperatures from 32 degrees F to 175 degrees F, making it suitable for year-round shop use. Licensed HVAC technicians, machinists, and pneumatic tool operators install and use this blow gun for directed airflow tasks including cleaning, debris removal, and equipment blowdown.

The 640S is intended for use with pneumatic grinders, sanders, and similar compressed-air-driven equipment in industrial, automotive, and mechanical service environments. Its compact form factor and 3/4-inch tube length make it easy to direct airflow in tight spaces. The full-flow straight nozzle design provides maximum airflow efficiency without sacrificing control. This blow gun meets OSHA 1910.242(b) and OSHA 1910.95 standards, making it compliant for use in regulated workplace environments where chip guarding and noise exposure requirements apply.

Installation Notes

Installation is performed by pneumatic system technicians or qualified shop personnel. Depressurize the air line completely before attaching or removing the blow gun from the 1/4 NPT fitting. Use appropriate thread sealant on the NPT connection per shop or facility standards. Always verify the connected air supply pressure does not exceed the equipment rating before operation.
