This 42-inch fan delivers 18,197 CFM of airflow and is powered by a 1-1\/2 HP motor running on 115\/230 volts, single phase. Designed for single-speed operation, the belt drive configuration allows for flexible motor placement and quieter operation compared to direct drive alternatives. At 225 pounds, this is a heavy-duty unit intended for permanent or semi-permanent installation by experienced mechanical contractors or industrial maintenance personnel.\u003c\/p\u003e\n\u003cp\u003eThe AIRMASTER 42798 is suited for large-scale ventilation in warehouses, manufacturing facilities, agricultural buildings, and similar high-volume air movement environments. Single-phase power makes it compatible with standard commercial electrical service without requiring three-phase infrastructure. The 42-inch blade diameter and high-pressure design allow it to move air efficiently against resistance, making it appropriate for ducted or semi-ducted installations where static pressure is a factor.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e42-inch fan diameter for high-volume airflow in large spaces\u003c\/li\u003e\n  \u003cli\u003e18,197 CFM rated airflow output\u003c\/li\u003e\n  \u003cli\u003eBelt drive design for flexible motor positioning and reduced vibration transfer\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 HP single-phase motor, operable at 115 or 230 volts\u003c\/li\u003e\n  \u003cli\u003eSingle-speed operation for straightforward installation and control\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty construction at 225 pounds for permanent mounting applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit unit corresponding to AIRMASTER model HA42KA.

Disconnect and lock out all power before servicing or mounting. The 115\/230-volt dual-voltage motor must be wired to match the available supply voltage per NEC requirements before energizing. Ensure the mounting structure is rated to support the unit weight and that belt tension and pulley alignment are verified before initial startup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFan Diameter\u003c\/strong\u003e: 42 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAirflow\u003c\/strong\u003e: 18,197 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Horsepower\u003c\/strong\u003e: 1.5 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 115\/230 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePhase\u003c\/strong\u003e: 1 Phase\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Belt Drive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpeed\u003c\/strong\u003e: Single Speed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 43.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 43 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 225 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: AIRMASTER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 42798\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIRMASTER","offers":[{"title":"Default Title","offer_id":51345265393970,"sku":"42798","price":2593.37,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310460648.jpg?v=1782053372","url":"https:\/\/voomisupply.com\/products\/airmaster-42798-high-pressure-belt-drive-fan-42-in-1-5-hp","provider":"Voomi Supply","version":"1.0","type":"link"}
