When the air surrounding a compressor is unsuitable for the intended use, a Remote Air Intake is required. Designed for use with Nuvair's Mini Tech compressors, Remote Air Intakes draw fresh air away from a compressor’s location. A remote source of fresh air is critical when using engine-powered compressors due to carbon monoxide (CO) in gas and diesel engine exhaust fumes. Standard hose length: 15 feet (4.5 m). Quick disconnect fittings come as standard equipment.
