Application

  • Ultra low leakage design
  • Independently tested
  • 2.76 m3/hr/m2 leakage at 50 Pa static pressure
  • Corrosion resistant materials used throughout
  • Purpose designed for natural ventilation systems
  • Available factory fitted with a full range of actuators

An ultra high shut off volume control damper, the LF uPVC VCD is purpose designed for the next generation of natural ventilation systems and highly energy efficient buildings.

Making use of corrosion resistant materials, these dampers are also suitable for coastal or marine installations like oil rigs, and also in swimming pools where the chlorinated atmosphere can quickly corrode even stainless steel volume control dampers.

Description

LF uPVC plastic volume control dampers are entirely constructed from lightweight and corrosion resistant materials, making use of uPVC, aluminium and stainless steel. This gives this model of VCD an inherent resistance to corrosion, far in excess of galvanised steel units.

The LF uPVC VCD has been independently tested and confirmed to have a leakage rate of just 2.76 m3/hr/ms at 50 Pa of static pressure. This is over 70% better than the 10 m3/s/m2 requirement set out in Part L of Building Regulations.

We recommend the use of Belimo actuators for control, and can supply the full range of open close, modulating or spring return models factory fitted to uPVC VCDs. Within natural ventilation applications the use of penthouse louvres is also becoming a preffered system.

Options


Actuators

The recently overhauled blade and seal design means small, cost effective actuators can now be used with LF uPVC VCDs. See the downloadable PDF for more details.

Manual Control Options

Cast aluminium locking quadrants with their integrated visual position indicator are the only hand control option we recommend for use with uPVC Volume Control Dampers

Spigots

If the standard flanged option is not suitable, square, circular or flat oval spigots can be fitted
