It accepts a 3\/8 NPT inlet connection and delivers up to 56 standard cubic feet per minute (SCFM) of airflow with a maximum transmissible thrust of 3.20 units. The zinc construction provides solid corrosion resistance in typical shop and production environments. Operating temperatures range from -30 degrees F to 180 degrees F, making it suitable for both cold-storage and warm-production floor use. Maintenance technicians, production workers, and trade professionals in HVAC, plumbing, and industrial settings use this blow gun for part cleaning, debris removal, and general compressed-air work.\u003c\/p\u003e\n\u003cp\u003eThe U74MAC is suited for use at stationary compressor drops or portable compressor setups where a 3\/8 NPT connection is present. It is appropriate for general industrial, manufacturing, and mechanical service environments. The Maximum Air Cluster tip concentrates airflow for effective debris clearing on parts, equipment surfaces, and work areas. Its wide operating temperature range supports use in refrigerated warehouses, outdoor service vehicles, and heated production floors without requiring a seasonal tool swap.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaximum Air Cluster tip delivers up to 56 SCFM for high-volume blowoff applications\u003c\/li\u003e\n  \u003cli\u003eZinc body construction provides durability and corrosion resistance in shop environments\u003c\/li\u003e\n  \u003cli\u003e3\/8 NPT inlet fits standard industrial compressed-air supply lines\u003c\/li\u003e\n  \u003cli\u003eOperating range of -30 degrees F to 180 degrees F covers a broad range of service conditions\u003c\/li\u003e\n  \u003cli\u003e82 decibel rating indicates relatively low noise output for a high-flow blow gun\u003c\/li\u003e\n  \u003cli\u003eMaximum transmissible thrust of 3.20 for directed cleaning force on stubborn debris\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard compressed-air systems equipped with a 3\/8 NPT supply port or quick-connect adapter sized for 3\/8 NPT threads.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified technician or trained maintenance professional. Shut off and bleed the compressed-air supply line to zero pressure before connecting or disconnecting the blow gun. Apply thread sealant tape to the 3\/8 NPT male threads before making the connection to prevent air leaks. Always point the nozzle away from personnel when restoring air pressure and follow applicable OSHA and facility safety standards for compressed-air tool use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Type\u003c\/strong\u003e: Maximum Air Cluster\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Thread Size\u003c\/strong\u003e: 3\/8 NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAirflow\u003c\/strong\u003e: 56.00 SCFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Transmissible Thrust\u003c\/strong\u003e: 3.20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDecibel Rating\u003c\/strong\u003e: 82 dB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 180 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: -30 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.92 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GUARDAIR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: U74MAC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUARDAIR","offers":[{"title":"Default Title","offer_id":51539446006066,"sku":"U74MAC","price":318.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cda1a90fb4b26674ee020d50e68fac34.jpg?v=1785840410","url":"https:\/\/voomisupply.com\/products\/guardair-u74mac-air-blow-gun-maximum-air-cluster-3-8-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
