Air Dampers – Perfect for a Wide Variety of Applications At Johnson Controls, we offer Damper Controls in a diverse range of models. Dimensions of Dampers Minimum size of IOOmm (width) x IOOmm (height) For example, in a house, the main floor may be served by one heating zone while the upstairs bedrooms are served by another. A slimline volume control damper is also available. This is usually done in the summer, but also sometimes in the winter between uses. In order to improve efficiency and occupant comfort, HVAC systems are commonly divided up into multiple zones. Each approach has advantages and disadvantages. Volume control dampers; Categories & Filters. Volume Control Damper Achieve simple and cost effective manual flow control application with the Wozair Volume Control Damper (VCD). Operating pressure: 1000 Pa. Another style of electrically powered damper uses a spring-return mechanism and a shaded-pole synchronous motor. However, in most applications "fail safe" indicates the damper will close upon loss of power thus preventing the spread of smoke and fire to other areas. As with the second style of electrical zone dampers, these dampers automatically return to the default position without the application of any power, and the default position is usually "open", allowing air to flow. This allows air to continue to flow while the heat exchanger in a furnace cools down after a heating period completes. Gear-action manual operator for large dampers. Regardless of the style of damper employed, the systems are often designed so that when no thermostat is calling for air, all dampers in the system are opened. Keywords: Search . The Bullock Model 6700 Air Volume Control Damper with its unique design gives great control of air passing through air-conditioning or ventilation systems, either manually using a quadrant control or via the use of building system actuators. Fire Protection. In a chimney flue, a damper closes off the flue to keep the weather (and birds and other animals) out and warm or cool air in. Share page. The damper may be accessible only by reaching up into the fireplace by hand or with a woodpoker, or sometimes by a lever or knob that sticks down or out. A system with zone dampers is dependent upon a single furnace. With its opposed blade operation closing system, volume control damper (VCD) is designed for controlling air flow and pressure in HVAC systems. Every damper is built with performance in mind and tested per AMCA standards in Ruskin's Laboratory. Leminar Control dampers are manufactured to meet the most stringent specifications and quality standards using our vast experience and expertise in the field.Automatic intake dampers and manual balancing dampers are available in our range of products for various applications. Non-metallic bearings prevent metal to metal contact. Motorized Volume Control Damper. Volume Control Damper – AVCD. A damper may be used to cut off central air conditioning (heating or cooling) to an unused room, or to regulate it for room-by-room temperature and climate control. team.vav@connols-air.com, Tunnel Vent and Fire-Smoke Damper: These dampers also may allow adjustment of the "closed" position so that they only obstruct, for example, 75% of the air flow when closed. VAV Terminals. Air Control Dampers. Frame in 18 G and blades are manufactured in 20 G galvanized mild steel. Clean Room Technology. Singapore 629034, Air Distribution Equipment: Vertical Type Defrosting Heater; Horizontal Type Defrosting Heater; Fan Heater. PRODUCT DESCRIPTION. 5. In either case, the motor is usually connected to the damper via a mechanical coupling. On a wood-burning stove or similar device, it is usually a handle on the vent duct as in an air conditioning system. product range.
