The 1\/4 NPT female inlet connects to standard shop air lines, and the all-brass body and nozzle construction handle continuous-duty use without corrosion concerns. At a rated flow of 32 standard cubic feet per minute (SCFM) and a decibel rating of 87 dB, the 74GHVB delivers high-volume airflow while staying within common occupational noise exposure guidelines. Overall length is 6.7 inches, and the unit weighs 0.65 pounds, making it easy to handle during extended tasks. Operating temperature range runs from -30 degrees F to 180 degrees F.\u003c\/p\u003e\n\u003cp\u003eThe 74GHVB suits general blow-off and debris-clearing applications in HVAC shops, plumbing facilities, machine shops, and light manufacturing environments. Technicians use it to clear chips, dust, and moisture from work surfaces, parts, and equipment. The high volume safety nozzle design limits maximum transmissible thrust to 1.80 ounce-force, which is consistent with OSHA dead-end pressure safety requirements for air blow guns. It is appropriate for any compressed-air system with a 1\/4 NPT supply port.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh volume safety nozzle rated at 32 SCFM airflow\u003c\/li\u003e\n  \u003cli\u003eAll-brass body and nozzle for corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003e1\/4 NPT female inlet fits standard shop air connections\u003c\/li\u003e\n  \u003cli\u003e87 dB noise rating supports compliance with common occupational exposure limits\u003c\/li\u003e\n  \u003cli\u003eMaximum transmissible thrust of 1.80 ounce-force meets OSHA dead-end pressure guidelines\u003c\/li\u003e\n  \u003cli\u003eWide operating range of -30 degrees F to 180 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with compressed-air systems equipped with a 1\/4 NPT female threaded supply port.

Depressurize and lock out the air supply line before connecting or disconnecting the blow gun. Apply thread sealant tape to the male NPT fitting on the supply line per standard practice before threading the gun inlet hand-tight, then wrench-tighten to seat the connection without over-torquing brass threads. Always direct airflow away from personnel during use and wear appropriate eye protection in accordance with applicable shop safety standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Thread\u003c\/strong\u003e: 1\/4 NPT (FNPT)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNozzle Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNozzle Type\u003c\/strong\u003e: High Volume Safety Nozzle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 32 SCFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDecibel Rating\u003c\/strong\u003e: 87 dB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Transmissible Thrust\u003c\/strong\u003e: 1.80 ounce-force\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.7 inches\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: 0.65 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: 74GHVB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUARDAIR","offers":[{"title":"Default Title","offer_id":51538301190450,"sku":"74GHVB","price":109.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9b6add6a7967dd97bd6875152ef52a10.jpg?v=1785822313","url":"https:\/\/voomisupply.com\/products\/guardair-74ghvb-air-blow-gun-high-volume-safety-nozzle","provider":"Voomi Supply","version":"1.0","type":"link"}
