Airborne dust, dirt, trash and debris can be a real problem for heavy equipment and vehicle engines. Cooling systems routinely suck in foreign objects that collect on radiator fins and other surfaces. Ineffective or infrequent cleaning can lead to engine overheating, engine failure, or worse. Designed to quickly and effectively blast away debris, the Guardair Radiator Gun features a bi-directional multi-port, linear nozzle that delivers a powerful, wide spray pattern of compressed air. By incorporating the linear nozzle into the tip of a ½" diameter, 60" heavy-duty stainless steel extension, this configuration provides unparalleled cleaning within hard-to-access radiator housings and engine bays. The rugged, in-line style, thermally insulated handle features a dead-man trigger for safe operation, and an adjustable auxiliary handle provides sure two-handed control. Equipped with a ¾”FNPT inlet, the Radiator Gun can also be ordered with a Universal "Chicago Style" swivel coupling. Compressed air to power the Guardair Radiator Gun is typically supplied by a 185 cfm tow-behind, or stationary in-plant compressor.
