Guardair 900LJ072AA Air Blow Gun Safety Extension Tube

Product Description

The GUARDAIR 900LJ072AA is an OSHA-compliant air blow gun designed for industrial and shop use where extended reach is required. It features a 72-inch aluminum safety extension tube, a thumb-lever actuator, and a 1/4 NPT female inlet. The compact thumb-switch design fits in the palm of the hand for single-handed operation during sustained blowdown tasks. At 75.4 inches overall length and an airflow rating of 16 SCFM, it delivers controlled airflow for clearing chips, debris, or contamination from deep cavities, machinery channels, and hard-to-reach areas. Licensed tradespeople and industrial maintenance techs are the primary installers and users.

This blow gun is suited for compressed-air systems in manufacturing, automotive, HVAC service, and general industrial maintenance environments. The 72-inch tube length makes it especially practical for cleaning inside ductwork, conduit runs, deep machine housings, and confined areas where a standard short-barrel blow gun cannot reach. The aluminum body and nozzle keep weight manageable across the full 75.4-inch span. It connects directly to a standard 1/4 NPT compressed-air line or quick-connect fitting.

Key Features

• 72-inch aluminum safety extension tube for deep-reach blowdown applications
• Thumb-lever actuator with compact palm-fit design for single-handed use
• OSHA-compliant airflow design rated at 16 SCFM
• 1/4 NPT female inlet compatible with standard shop-air fittings
• All-aluminum body and nozzle construction for lightweight durability
• Noise rating of 100 dB noted — hearing protection is recommended during use

Compatibility

Designed for use with compressed-air systems equipped with a 1/4 NPT female threaded inlet connection. Compatible with standard shop-air quick-connect adapters and inline regulators using 1/4 NPT male fittings.

Installation Notes

Installation and connection should be performed by a qualified technician familiar with compressed-air systems. Depressurize the air line completely before attaching or removing the blow gun. Verify the supply line pressure does not exceed the rated capacity of the tool and fittings. Eye and hearing protection are required during operation given the 100 dB noise rating and directed high-velocity airflow.
