It delivers 105 standard cubic feet per minute (SCFM) through a 48-inch rigid tube, giving technicians extended reach without repositioning. The 3\/4 NPT inlet threads directly onto standard compressed air supply lines. At a decibel rating of 124 dB, hearing protection is required during operation. Licensed trades and maintenance professionals working in manufacturing, HVAC mechanical rooms, and fabrication shops are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThe HT139 is suited for stationary and portable compressed air systems where high-volume airflow is needed across a distance. The 48-inch tube length makes it practical for blowing out ductwork, clearing debris from machinery, purging condensate from drain lines, and drying components after wet service work. It is commonly used in commercial and industrial settings where a standard short-barrel blow gun lacks the reach or flow volume for the task at hand.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSupersonic nozzle delivers 105 SCFM for high-volume air displacement\u003c\/li\u003e\n\u003cli\u003e48-inch tube provides extended reach into confined or deep workspaces\u003c\/li\u003e\n\u003cli\u003e3\/4 NPT inlet fits standard compressed air supply connections\u003c\/li\u003e\n\u003cli\u003eRigid tube construction supports precise directional airflow\u003c\/li\u003e\n\u003cli\u003eDecibel rating of 124 dB — PPE required per OSHA noise exposure standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with compressed air supply systems equipped with a 3\/4 NPT threaded outlet.

Always depressurize and isolate the air supply line before threading or unthreading the inlet connection. Verify that the supply line pressure rating is compatible with the tool before operation. Hearing protection must be worn during use given the 124 dB output level, in compliance with applicable OSHA noise exposure regulations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Type\u003c\/strong\u003e: Supersonic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 105 SCFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDecibel Rating\u003c\/strong\u003e: 124 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Length\u003c\/strong\u003e: 48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Thread Size\u003c\/strong\u003e: 3\/4 NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 60 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 9.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: HT139\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUARDAIR","offers":[{"title":"Default Title","offer_id":51541549711666,"sku":"HT139","price":1613.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/032d3979cbc066a24f190aa8b2c041cc.jpg?v=1785879111","url":"https:\/\/voomisupply.com\/products\/guardair-ht139-air-blow-gun-supersonic-nozzle-105-scfm","provider":"Voomi Supply","version":"1.0","type":"link"}
