Airflow Duplexvent DV72 including the Quiet-Vent Semi Rigid Radial Ducting Kits
A heat recovery ventilation system is only as good as the ducting used
Following years of heat recovery design and installation BPC Ventilation are now able to provide high quality kits that will provide a quiet and efficient system exceeding building control regulations and are suitable for any competent person to successfully install
The Quiet-Vent radial semi rigid system combines the performance benefits of rigid duct and the installation benefits of flexible duct by treating each room individually with a dedicated 75mm duct run from two manifolds (distribution box) for supply and extract air at the heat recovery unit
Quiet-Vent Semi Rigid Duct is a perfect choice for MVHR Heat Recovery System Installations as it provides huge performance benefits whilst dramatically reducing installation time and installation risk on-site
- The pipes have a smooth bore that is hygienic, anti-static, non-porous and odourless which inhibits mould and bacteria growth with low air-flow resistance and has high sound absorption.
- The round 75mm pipe is supplied in 50-meter-long rolls and takes more than 13 Kilonewton’s per square metre of pressure to crush it and can even be buried in up to 3 metres of concrete.
- No noise transfer (talking, music etc) between rooms (As required and stated in the 2010 Domestic Ventilation Compliance Guide).
- No noise generated by high volumes of air being pushed or sucked down ducting (common with branch systems).
- No joins in ducting so it cannot become dislodged if knocked or disturbed e.g. in loft spaces.
- 70% Quicker and easier to install compared to traditional branch systems.
- Metal distribution boxes – very robust and durable, various sizes.
- Can easily overcome site obstacles and can be worked through around joists with ease
- Fully cleanable and one of the only systems on the market that is - making it ideal for Heat Recovery System installations as it offers long-term Guaranteed Installed Performance
- Superior 100% airtightness as there is up to 85% less joins and any fittings use rubber seals
- Ideal for metal web and engineer joists
- SAP Appendix Q and Passive House Approved (classed as solid rigid on SAP)

Installation and commissioning
All systems on completion of the installation require commissioning to insure it is working as intended, BPC have a network of commissioning engineers or we can supply you with a DIY air meter including a commissioning guide
The systems have been painstaking designed to be suitable for any competent person to install but we also have a large network of installers if required throughout the UK and Ireland if required
How does a Radial system work?
Radial ducting is the latest innovation on ventilation systems and can provide a quieter and more efficient ventilation system compared to rigid ductwork.
Radial Ducting is a system of individual smooth bore pipes which are crushproof, semi flexible with zero air loss. The pipes have an anti-static and antibacterial lining which individually connects each room to a manifold
The manifold takes mass airflow directly from the MVHR Heat Recovery Unit and allows lower rates to pass through to each individual room run eliminating noise transfer and increasing the efficiency of the heat recovery unit
The radial ducting is designed to be installed below the loft insulation to provide a superior heat retention over pre-insulated solid rigid above the loft insulation
Radial semi rigid ducting is suitable for any type of property; including timber framed houses, passive house approval homes and can be used in areas with limited access.
The radial semi rigid ducting is available in both circular (75mm or 90mm) and oval (51mmx114mm) fittings.
Alternative duct options
We can also stock and supply Solid Rigid PVC, Galvanised Steel and Thermal EPP (foam) ducting if preferred
