Ultra-Low Leakage uPVC VCD Test Results

uPVC VCDs for Natural Ventilation Systems

As the core component of our natural ventilation range, it has been imperative to prove our brand new uPVC volume control damper has real world, certifiable performance.

Sporting unique features like an off centre blade axle allowing full length side seals, we already knew we would see fantastic results. So, keen to prove what we suspected, a damper 1000mm x 806mm nominal was sent for testing, the large size tantamount to our confidence in the uPVC volume control damper's performance. The results however amazed even us.

Static pressure and leakage results:

10Pa - 0.00m³/hr/m²
25Pa - 3.83m³/hr/m²
50Pa - 12.73m³/hr/m²
75Pa - 22.22m³/hr/m²
100Pa - 24.11m³/hr/m²
150Pa - 35.33m³/hr/m²

With natural ventilation systems rarely if ever exceeding pressures of 10Pa, it is clear how HVC uPVC volume control dampers can greatly enhance the overall efficiency of your system.

uPVC volume control dampers are available now, as a standalone damper, or in ready made natural ventilation units incorporating an external louvre, uPVC VCD and an internal grille. Designed as window replacement units, these have been purpose created as a highly efficient, easy to install unit, perfect for the next generation of schools throughout the UK.
