Guardair ASU4150KT Utility Air-spade Blow Gun Kit

Product Description

The GUARDAIR ASU4150KT is a complete utility air-spade blow gun kit designed for high-volume air-powered excavation, debris clearing, and surface cleaning tasks in industrial and trade environments. The kit operates at up to 120 psi through a 3/4 NPT inlet and delivers airflow through a 150 CFM non-sparking brass nozzle, making it suitable for use around sensitive equipment, combustible materials, or confined workspaces. The assembly includes all major components needed for immediate deployment. Licensed contractors and maintenance professionals in facilities, construction, and heavy industry are the primary users of this kit.

This kit is built for utility excavation and air-spade applications in commercial and industrial settings. The 4-inch insulated barrel with dirt shield protects the operator during ground-level work, while the 45-degree non-sparking brass angled adapter allows access to tight or awkward installation angles. The included 1-inch ID by 10-foot lightweight air hose with Chicago-style connector provides reach without excessive drag. The 3-foot insulated extension and non-sparking brass coupler extend the working length for deeper or harder-to-reach areas. Heavy-duty locking storage is included for job-site organization and transport.

Key Features

• 150 CFM non-sparking brass nozzle rated for use around combustible or static-sensitive materials
• 3/4 NPT inlet connection compatible with standard compressed air supply lines
• 120 psi maximum operating pressure for consistent high-volume airflow
• 4-inch insulated barrel with dirt shield for operator protection during excavation tasks
• 45-degree non-sparking brass angled adapter included for restricted-access work angles
• Heavy-duty locking storage case included for secure transport and job-site storage

Compatibility

Designed for use with compressed air systems supplying a 3/4 NPT threaded connection at up to 120 psi. The Chicago-style connector on the included air hose fits standard Chicago-style air supply couplers commonly found on industrial compressor setups.

Installation Notes

Installation and operation should be performed by qualified personnel familiar with compressed air systems and applicable OSHA regulations for air tool use. Shut off and bleed the air supply before connecting or disconnecting any fittings. Verify that the supply line pressure does not exceed 120 psi before operation. Ensure all non-sparking components remain intact and undamaged before use in environments with combustible dust or vapors.
