The Guardair Long John is a compressed-air blow gun with a 12-inch aluminum extension and a pistol-style grip. Its Venturi nozzle boosts thrust up to 200% over a standard air gun while limiting static pressure to under 30 psi if the tip is blocked, which is how it meets OSHA cleaning requirements. The long reach suits tanks, ovens, molds, rafters and machinery where a short gun can't get close. It is a focused industrial tool rather than a general-purpose shop blower, and its aluminum body and hanging hook are built for daily workplace use.

The Guardair Long John is a safety air gun with a 12-inch aluminum extension and a pistol-style grip. It has a 1/4 inch FNPT inlet and protects against chip flyback. It is used for blowing debris from floors, masonry forms, tanks, ovens, molds, rafters, machinery and storage areas.
The Venturi nozzle boosts thrust up to 200% over standard air guns. If the tip becomes blocked, it limits static pressure to less than 30 psi. The gun is designed and tested to meet OSHA standards for cleaning with compressed air.
The ergonomic handle and lightweight aluminum body reduce hand strain. A hanging hook allows storage when the gun is not in use. It is made in Massachusetts by Guardair.
