Guardair ASU4150G4 Air Blow Gun 150 Scfm 48 Inch 3/4 Npt

Product Description

The GUARDAIR ASU4150G4 is a heavy-duty air blow gun designed for industrial and trade applications where spark risk is a concern. It features a non-sparking brass nozzle and a 48-inch rigid tube, making it well suited for reaching into confined spaces, machinery, and deep enclosures. The gun delivers up to 150 standard cubic feet per minute (SCFM) of airflow through a 3/4 NPT inlet. At 121 decibels, users should follow applicable OSHA hearing protection guidelines during operation. Licensed maintenance technicians, industrial mechanics, and facility service professionals are the primary installers and operators of this tool.

The ASU4150G4 is used in manufacturing facilities, refineries, chemical processing plants, and other environments where flammable materials, dust, or vapor may be present. The non-sparking brass nozzle reduces ignition risk in classified or sensitive areas. The 48-inch tube length allows operators to direct airflow into hard-to-reach locations without repositioning equipment. This blow gun is appropriate for general purging, debris clearing, and drying tasks in both light industrial and heavy industrial settings.

Key Features

• Non-sparking brass nozzle reduces ignition risk in flammable or vapor-present environments
• 48-inch tube length provides extended reach into confined spaces and deep enclosures
• 150 SCFM airflow rating delivers high-volume air delivery for purging and debris clearing
• 3/4 NPT inlet connects to standard industrial compressed air supply lines
• 121 dB rated — hearing protection required per applicable safety standards

Compatibility

Designed for use with standard industrial compressed air systems equipped with a 3/4 NPT supply connection. Verify system pressure ratings are compatible with the blow gun before installation.

Installation Notes

Installation and operation should be performed by qualified maintenance technicians or industrial service professionals familiar with compressed air systems. Shut off and bleed compressed air supply pressure before connecting or disconnecting the blow gun from the supply line. Follow all applicable OSHA standards for compressed air use, including requirements for hearing protection at noise levels above 85 dB. Never direct airflow at personnel or use the tool for purposes other than its intended industrial application.
