Guardair 74GAA Adjustable Safety Air Blow Gun 1/4 Npt

Product Description

The GUARDAIR 74GAA is an adjustable safety air blow gun designed for controlled compressed air discharge in industrial and shop environments. The aluminum body keeps weight low at 0.61 pounds while the zinc adjustable safety nozzle allows the operator to direct airflow precisely without exceeding a maximum transmissible thrust of 0.80 ounces, meeting OSHA dead-end pressure guidelines. At a 79-decibel rating, it operates at a lower noise level than many standard blow guns. The 1/4 NPT female inlet threads onto standard shop air lines, and the 6.7-inch overall length keeps it maneuverable in tight spaces. Airflow is rated at 13 SCFM. Maintenance techs, machinists, and assembly workers are the typical end users.

The 74GAA suits general-purpose blowoff tasks in manufacturing facilities, automotive shops, HVAC service bays, and light industrial settings. It is well suited for clearing chips and debris from machined parts, blowing out filters, drying components after washing, and cleaning hard-to-reach areas around equipment. The adjustable safety nozzle tip allows variable airflow direction without tool changes. Operating temperature range runs from -30 degrees F to 180 degrees F, making it usable in refrigerated workspaces as well as warm shop environments.

Key Features

• Adjustable safety nozzle tip limits dead-end pressure thrust to 0.80 ounces for OSHA compliance
• 79 dB noise rating reduces acoustic exposure compared to open-pipe blowoffs
• 13 SCFM airflow at rated conditions for efficient debris clearance
• Aluminum body construction for lightweight durability at 0.61 pounds
• 1/4 NPT female inlet fits standard shop air quick-connect fittings
• Wide operating range of -30 degrees F to 180 degrees F

Compatibility

Designed as a direct-connect replacement or addition to any compressed air system with a 1/4 NPT female threaded outlet or quick-disconnect adapter.

Installation Notes

Installation is performed by maintenance personnel or any qualified technician. Depressurize the air line before threading the blow gun onto the supply fitting to prevent uncontrolled air release. Use thread sealant tape on the 1/4 NPT male supply fitting and tighten hand-tight plus an additional quarter turn — do not overtighten aluminum-threaded connections. Verify the operating pressure of the supply line does not exceed the rated limits of the blow gun before returning the line to service.
