Powered entirely by compressed air through a 1\/2 inch NPT inlet, it produces airflow without motors, switches, or electrical connections, making it rated for hazardous locations. The galvanized steel horn and steel housing measure 30.5 inches in overall length, with a 7.31 inch base diameter and a 7 inch face diameter. At 80 psig inlet pressure, air consumption is 40 CFM; at 60 psig, it draws 30 CFM. Maximum inlet pressure is 100 psig. Licensed contractors and industrial safety personnel install this unit where spark-free, explosion-safe ventilation is required.\u003c\/p\u003e\n\u003cp\u003eThe 9518-03 is designed for active air movement in industrial environments where electrical equipment is prohibited or impractical. Typical applications include refineries, utility and power plants, shipyards, paper and pulp plants, the marine and steel industry, and manhole operations. Its venturi design entrains surrounding air to multiply the effective airflow beyond the compressed air volume alone, making it well suited for purging confined spaces, ventilating tanks, and clearing fumes in restricted areas prior to or during hot work and entry operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVenturi-style operation requires only compressed air — no electricity, no motor, no ignition risk\u003c\/li\u003e\n  \u003cli\u003eRated for hazardous locations, suitable for use in explosive or flammable atmospheres\u003c\/li\u003e\n  \u003cli\u003eGalvanized steel horn construction resists corrosion in wet and chemical-exposure environments\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch NPT inlet connects directly to standard compressed air supply lines\u003c\/li\u003e\n  \u003cli\u003e40 CFM air consumption at 80 psig; 30 CFM at 60 psig with a 100 psig maximum inlet pressure\u003c\/li\u003e\n  \u003cli\u003e0.4 inch base slot diameter accommodates standard blower positioning and mounting configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in industrial ventilation systems where a compressed air supply at up to 100 psig is available.

Before connecting, verify that the supply line pressure does not exceed the 100 psig maximum inlet rating. Ensure all compressed air supply lines are depressurized before making or breaking NPT connections. In hazardous-location applications, follow applicable OSHA confined space entry standards and any site-specific hot work or atmospheric testing requirements before deploying the blower.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 30.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Diameter\u003c\/strong\u003e: 7.31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Slot Diameter\u003c\/strong\u003e: 0.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Connection\u003c\/strong\u003e: 1\/2 inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Inlet Pressure\u003c\/strong\u003e: 100 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Consumption at 80 psig\u003c\/strong\u003e: 40 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Consumption at 60 psig\u003c\/strong\u003e: 30 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorn Material\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHazardous Location Rated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 12 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40101601\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: ALLEGRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9518-03\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLEGRO INDUSTRIES","offers":[{"title":"Default Title","offer_id":51538947637554,"sku":"9518-03","price":389.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd817e1f14c5f815bbed6399f18a6610.jpg?v=1785830527","url":"https:\/\/voomisupply.com\/products\/allegro-9518-03-venturi-pneumatic-blower-30-5-in-galvanized","provider":"Voomi Supply","version":"1.0","type":"link"}
