It operates without motors or gears, using low-pressure air supplied by a medical-grade pump inside the Arzel Zoning control panel to open and close via pneumatic tubing. This motorless actuation method reduces mechanical failure points and contributes to long-term reliability. Licensed HVAC technicians install this damper as part of a complete Arzel Zoning system, where it regulates airflow to individual zones in residential or light commercial ductwork.\u003c\/p\u003e\u003cp\u003eThe stk-er0009 is suited for installation in round metal ductwork as part of a multi-zone HVAC system. Its insertable design makes it compatible with retrofit applications, eliminating the need to replace existing duct runs. The damper connects to the zoning panel via standard pneumatic tubing and responds to pressure or vacuum signals from the panel pump to modulate zone airflow. It is part of a product line that includes 70 stock sizes, with sleeved variants available for non-metal ductwork installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMotorless pneumatic actuation using low-pressure air from a medical-grade panel pump\u003c\/li\u003e\n\u003cli\u003eInsertable design supports retrofit installations in existing round metal ductwork\u003c\/li\u003e\n\u003cli\u003eConnects to Arzel Zoning control panels via pneumatic tubing — no electrical wiring to the damper\u003c\/li\u003e\n\u003cli\u003eRound profile, 9 inches in diameter, fits standard 9-inch round duct openings\u003c\/li\u003e\n\u003cli\u003ePart of a 70-size product family for broad duct size coverage\u003c\/li\u003e\n\u003cli\u003eSleeved versions available separately for non-metal ductwork applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with any Arzel Zoning panel.

The technician cuts a hole in the metal duct, inserts the damper body, and secures it with screws. Pneumatic tubing is then routed from the damper to the Arzel Zoning control panel. Power down the zoning system and depressurize the pneumatic circuit before servicing or replacing a damper.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\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\u003eDuctwork Compatibility\u003c\/strong\u003e: Metal duct (sleeved versions 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-er0009\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARZEL ZONING TECHNOLOGY","offers":[{"title":"Default Title","offer_id":51620779131186,"sku":"STK-ER0009","price":129.04,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e980eb435212d4c701abc2ce23e2b178_d06f3100-2dee-4e39-8168-4bb25fc714aa.jpg?v=1787346307","url":"https:\/\/voomisupply.com\/products\/arzel-zoning-technology-stk-er0009-ezyslide-round-damper-9in","provider":"Voomi Supply","version":"1.0","type":"link"}
