Guardair 74GHVB Air Blow Gun High Volume Safety Nozzle

Product Description

The GUARDAIR 74GHVB is a brass air blow gun fitted with a high volume safety nozzle, designed for compressed-air blow-off tasks in industrial, mechanical, and trade shop environments. The 1/4 NPT female inlet connects to standard shop air lines, and the all-brass body and nozzle construction handle continuous-duty use without corrosion concerns. At a rated flow of 32 standard cubic feet per minute (SCFM) and a decibel rating of 87 dB, the 74GHVB delivers high-volume airflow while staying within common occupational noise exposure guidelines. Overall length is 6.7 inches, and the unit weighs 0.65 pounds, making it easy to handle during extended tasks. Operating temperature range runs from -30 degrees F to 180 degrees F.

The 74GHVB suits general blow-off and debris-clearing applications in HVAC shops, plumbing facilities, machine shops, and light manufacturing environments. Technicians use it to clear chips, dust, and moisture from work surfaces, parts, and equipment. The high volume safety nozzle design limits maximum transmissible thrust to 1.80 ounce-force, which is consistent with OSHA dead-end pressure safety requirements for air blow guns. It is appropriate for any compressed-air system with a 1/4 NPT supply port.

Installation Notes

Installation is performed by any qualified technician or maintenance professional familiar with compressed-air plumbing. Depressurize and lock out the air supply line before connecting or disconnecting the blow gun. Apply thread sealant tape to the male NPT fitting on the supply line per standard practice before threading the gun inlet hand-tight, then wrench-tighten to seat the connection without over-torquing brass threads. Always direct airflow away from personnel during use and wear appropriate eye protection in accordance with applicable shop safety standards.
