The GUARDAIR LZRN03 is a brass booster nozzle designed for use with Guardair Lazer Series blow guns. Measuring 1.75 inches in length with a 1/8 inch thread size, this nozzle attaches to compatible blow guns to direct and concentrate airflow for cleaning, drying, and debris removal tasks. It meets OSHA standards for safe compressed air use in industrial and shop environments. Weighing just 0.01 pounds, the LZRN03 is a lightweight, durable accessory suited for installation by maintenance technicians, HVAC service professionals, and industrial tradespeople who rely on precision air delivery tools.
The LZRN03 booster nozzle is intended for use in shop, facility maintenance, and light industrial settings where controlled compressed air application is required. It threads directly onto Guardair Lazer Series blow guns, making it a straightforward field replacement or upgrade nozzle. Typical applications include workbench cleaning, part drying, and targeted air blasting in confined areas. Its compact 1.75 inch length makes it suitable for use in tight spaces where a standard-length nozzle would be impractical.
Designed for use with Guardair Lazer Series blow guns as stated by the manufacturer. Verify thread size and blow gun model compatibility before installation.
Disconnect the compressed air supply and relieve line pressure before removing or installing any blow gun nozzle. Thread the LZRN03 by hand first to avoid cross-threading, then snug with an appropriate wrench. Do not overtighten brass fittings, as this can damage the threads. Compressed air equipment used in workplaces must comply with applicable OSHA regulations governing nozzle safety and operating pressure.
