It installs by sliding into a 1.25-inch slot cut into an existing round duct, eliminating the need to remove or replace duct sections. The double-layered blade design incorporates an integrated cellular foam sealing gasket, keeping leakage below 5 percent at static pressures up to 1 inch w.c. The 24-volt AC, 3-wire actuator operates as a power-open and power-close type, rated at 18 inch-pounds of torque. Licensed HVAC technicians and sheet metal contractors are the primary installers for this component in residential and light commercial zoning systems.\u003c\/p\u003e\n\u003cp\u003eThe ESID-6 is suited for retrofit zoning installations where existing round ductwork is being divided into independently controlled zones. The slip-in design allows field installation without major duct modification. The motor housing is NEMA 1 rated and includes an integrated terminal block for simplified low-voltage wiring. Adjustable end-stops allow technicians to set minimum and maximum blade positions, enabling precise CFM balancing for each zone or area served. The motor can be oriented at any angle around the duct circumference to accommodate tight mechanical room conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInstalls into a 1.25-inch slot cut into existing round duct — no full duct replacement required\u003c\/li\u003e\n  \u003cli\u003eDouble-layered blade with integrated cellular foam gasket for low-leakage performance below 5 percent at rated static pressure\u003c\/li\u003e\n  \u003cli\u003e24-volt AC, 3-wire power-open and power-close actuator rated at 18 inch-pounds of torque\u003c\/li\u003e\n  \u003cli\u003eAdjustable end-stops for minimum and maximum position settings to control design CFM per zone\u003c\/li\u003e\n  \u003cli\u003eIntegrated OPEN and CLOSE LED indicators plus a travel indicator for visual damper position confirmation\u003c\/li\u003e\n  \u003cli\u003eUL Listed motor actuator with NEMA 1 rated housing and integrated terminal block\u003c\/li\u003e\n  \u003cli\u003e5-year warranty with no scheduled maintenance required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style retrofit replacement or new-installation slip-in damper for 6-inch round duct systems operating on 24-volt AC, 3-wire zoning control circuits.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed HVAC technician or qualified sheet metal contractor. Shut down the air handler and de-energize the low-voltage control circuit at the transformer before cutting the duct slot or making wiring connections. A 1.25-inch slot must be field-cut cleanly around the full circumference of the round duct to accept the damper blade. Low-voltage wiring should comply with NEC Article 725 Class 2 circuit requirements for 24-volt control wiring.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Slip-In Damper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 24 volts AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Power Open \/ Power Close, 3-Wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTorque Rating\u003c\/strong\u003e: 18 inch-pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Static Pressure\u003c\/strong\u003e: 1 inch w.c.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeakage Rate\u003c\/strong\u003e: Less than 5 percent at rated static pressure\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Housing Rating\u003c\/strong\u003e: NEMA 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Listing\u003c\/strong\u003e: UL Listed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Air Quality and HVAC Zoning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: 5 Years\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: EWC CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ESID-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EWC CONTROLS","offers":[{"title":"Default Title","offer_id":51343008825650,"sku":"ESID-6","price":146.57,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554859.jpg?v=1782013631","url":"https:\/\/voomisupply.com\/products\/ewc-controls-esid-6-round-motorized-slip-in-damper-6-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
