It is designed for use in forced-air HVAC zoning systems where maintaining consistent static pressure is critical to system performance and equipment longevity. A built-in setscrew allows the installer to dial in the desired static pressure setpoint without guesswork or external gauges. The adjustment range runs from 0.3 inches WC to 0.8 inches WC. A static pressure indicator window confirms the current setpoint, and a blade indicator viewing window shows blade position during live system operation. HVAC technicians and zoning installers will find this damper straightforward to commission on the first visit.\u003c\/p\u003e\n\u003cp\u003eThe ECLBD-14 is suited for residential and light commercial forced-air zoning applications where a bypass damper is needed to manage excess static pressure when zone dampers close. Its round 14-inch profile fits standard round ductwork. The damper can be installed at any angle and in any orientation, which simplifies placement in tight mechanical rooms or unconventional duct runs. This flexibility reduces labor time during installation and eliminates the need to plan duct routing around fixed-orientation hardware. It is typically installed between the supply plenum and the return side of the system as part of a complete zoning assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSetscrew-adjustable static pressure from 0.3 to 0.8 inches WC eliminates manual bypass guesswork\u003c\/li\u003e\n  \u003cli\u003eStatic pressure indicator window displays current setpoint for quick field verification\u003c\/li\u003e\n  \u003cli\u003eBlade indicator viewing window shows live blade position during system operation\u003c\/li\u003e\n  \u003cli\u003eInstalls at any angle and any orientation for maximum placement flexibility\u003c\/li\u003e\n  \u003cli\u003eRated for up to 1800 CFM airflow capacity\u003c\/li\u003e\n  \u003cli\u003eRound 14-inch form factor fits standard round duct connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style pressure-regulating bypass damper for forced-air residential and light commercial HVAC zoning systems using 14-inch round ductwork.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with forced-air zoning systems. Power down the air handler or furnace at the disconnect before making any duct connections or wiring the damper into the zoning control panel. Use standard sheet metal screws and foil tape to secure and seal the duct connections. After installation, verify the static pressure setpoint through the indicator window before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Pressure Regulating Bypass Damper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAirflow Capacity\u003c\/strong\u003e: 1800 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStatic Pressure Adjustment Range\u003c\/strong\u003e: 0.3 to 0.8 inches WC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Air Quality \/ HVAC Zoning\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: ECLBD-14\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EWC CONTROLS","offers":[{"title":"Default Title","offer_id":51345775460658,"sku":"ECLBD-14","price":159.19,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554848.jpg?v=1782062568","url":"https:\/\/voomisupply.com\/products\/ewc-controls-eclbd-14-constant-load-bypass-damper-14-in","provider":"Voomi Supply","version":"1.0","type":"link"}
