HVAC Duct VCD Volume Control Damper

A J Services manufacture a selection of a volume control dampers or VCD which have been designed for fitting to the ducting in HVAC systems. Volume control damper help to regulate the air velocity which flows through the ducting which has been connected to a heating, ventilation and air conditioning system being able to regulate the volume of air passing through the ducting means that the rooms or space where the air is distributed will reach desired temperature faster. This means that less energy is used, which will ultimately mean lower energy bills. The dampers are manufactured in a variety of styles depending on the application they will be used within. With options for ducts with both high and low velocities, can be provided in a large number of sizes starting at 50mm with the largest going up to 2000mm. Because ducting changes shape depending on the system it is being implemented in the dampers which are provided reflect this and circular, oval, rectangular and square choices are available, with dampers being produced in galvanised, stainless 304/316 and aluminium. For the larger VCD in the rectangular dampers the blades can appear both in and out of the air stream, however because of the rectangular casing surrounding the larger circular VCD the blades will appear out of stream. These VCD are connected to the ducting via a spigot, so are slotted directly onto the ducting. For the smaller more specialised dampers such as single blade, constant volume and butterfly shutter the blades are most typically put of air stream as the components ergonomic design encompasses the blades inside the main housing of the damper
