Polypipe launches new Domus duct products for improved air flow and control

Polypipe Ventilation, manufacturer of market-leading domestic and light commercial ventilation systems, has added two exciting products to its Domus range of ducting systems: high-efficiency 90° bends and a new inlet/outlet plenum with integral flow control device.

New Polypipe products

Part of the Green Line range of energy-efficient ventilation systems and accessories, the Domus 90° bends provide up to 60% reduction in resistance to air flow, significantly lowering a duct system’s total pressure loss and therefore its overall energy use. In the case of ducting used as part of a mechanical ventilation with heat recovery system, this can also lead to cost savings as the certain properties may be able to use a smaller unit than previously possible.

The Domus 90° bends are available for use with Polypipe Ventilation’s best-selling Supertube 204mm x 60mm and Megaduct 220mm x 90mm rectangular rigid duct systems, ideal for applications that require higher air flow rates such as those associated with whole-house ventilation.

The unique design of the Domus Green Line 90° bends results in reduced air speed through the bend, lowering system noise as well as smoothing the air flow and helping to achieve higher air flow rates when required. All of these factors improve homeowner comfort as well as making central ventilation systems easier to specify.

Also for use with Polypipe’s Domus 204mm x 60mm Supertube rigid duct system is a new plenum with integral flow control device that can be used to regulate system air flows. This adaption enables the inlet/outlet plenum to be connected directly to a stylish architectural grille, taking away the need to fit a room-mounted adjustable air valve and instead giving specifiers, installers and homeowners the opportunity to match interior décor schemes. This clever design also allows for commissioning to be carried out in advance of construction of the finished ceiling, providing peace of mind that the required air flow rates will be achieved while the duct system is still accessible – which also means less risk of costly remedial work. Another advantage of the new plenum is that the flow control device cannot be easily tampered with by the occupant, something that could negatively effect system performance.

Domus ducting has a deserved reputation for quality and excellent technical support, in line with Polypipe’s position in the ventilation market. Polypipe Ventilation is well placed to offer immediate, practical solutions to Building Regulations Parts F and L. It continues to provide differentiated solutions in the private and social housing sectors, transforming the way developers, specifiers, installers, homeowners and distributors meet emerging environmental standards.
