It operates without motors or gears, relying instead on low-pressure air supplied by a medical-grade pump housed inside the Arzel Zoning control panel. Pneumatic tubing connects the damper to the panel, which delivers pressure or vacuum to open and close the blade. Licensed HVAC technicians install this damper by cutting a round hole into a metal duct, inserting the unit, and securing it with screws. The motorless, pneumatic design removes the most common points of mechanical failure found in motor-driven dampers.\u003c\/p\u003e\u003cp\u003eThe stk-er0014 is suited for residential and light-commercial forced-air zoning retrofits and new installations where metal round ductwork is present. Its insertable design makes it practical for retrofit work where duct access is limited and cutting into existing sheet metal is preferable to full duct replacement. Because actuation is pneumatic rather than electric, no low-voltage wiring to the damper itself is required. Arzel Zoning offers sleeved versions for non-metal ductwork applications where direct insertion into sheet metal is not feasible.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e14-inch round form factor for direct insertion into metal round ductwork\u003c\/li\u003e\n\u003cli\u003eMotorless pneumatic actuation eliminates gears, motors, and motor-related failures\u003c\/li\u003e\n\u003cli\u003eActuated by low-pressure air from a medical-grade pump inside the control panel\u003c\/li\u003e\n\u003cli\u003eConnected to the zoning control panel via pneumatic tubing, no low-voltage wiring to the damper\u003c\/li\u003e\n\u003cli\u003eRetrofit-friendly insertable installation — cut, insert, and secure with screws\u003c\/li\u003e\n\u003cli\u003ePart of a line spanning 70 stock sizes to cover a wide range of duct diameters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with any Arzel Zoning panel.

Before cutting into the duct, shut down the air handler and de-pressurize the system. Use appropriate sheet metal tools to cut a clean, correctly sized hole, insert the damper, and secure with self-tapping sheet metal screws. Route pneumatic tubing from the damper to the Arzel Zoning control panel per the panel manufacturer's instructions, observing minimum bend radius guidelines to avoid restricting airflow through the tubing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuation Type\u003c\/strong\u003e: Pneumatic (pressure and vacuum)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Supply\u003c\/strong\u003e: Low-pressure air from medical-grade panel pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuctwork Compatibility\u003c\/strong\u003e: Metal duct (sleeved variants available for non-metal)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ARZEL ZONING TECHNOLOGY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: stk-er0014\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARZEL ZONING TECHNOLOGY","offers":[{"title":"Default Title","offer_id":51621247582514,"sku":"STK-ER0014","price":157.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e980eb435212d4c701abc2ce23e2b178_2b4356c1-5d03-4ec2-8736-5db9746d1b8e.jpg?v=1787351888","url":"https:\/\/voomisupply.com\/products\/arzel-zoning-technology-stk-er0014-ezyslide-round-damper-14in","provider":"Voomi Supply","version":"1.0","type":"link"}
