Whatever the situation, Advance can be made to operate as needed. At the same time, automatic functions such as frost protection and summer bypass even have a choice of algorithms designed to suit different climates and lifestyles. The Vent-Axia Kinetic Advance SX Heat Recovery unit has optional control from Apple and Android smart phone applications
Integral Humidity Sensor
The integral humidity sensor increases speed in proportion to relative humidity levels, saving energy and reducing noise. The sensor also reacts to small but rapid increases in humidity, even if the normal trigger threshold is not reached. This unique feature ensures adequate ventilation, even for the smallest wet room. The night time relative humidity setback feature suppresses nuisance tripping as humidity gradually increases with falling temperature
The inner body is constructed of EPP and the outer enclosure is constructed of PVC
The unit features 2 x low energy, highly efficient EC/DC motors
Using the touch screen controller you can change the spigot controller configuration
The condensate drain can be taken out through the back, side or bottom of the unit. Using the fittings supplied, the final condensate connection is made outside the unit and can be completed after installation
In addition to a choice of compatible ducting systems a full range of controls, sensors, in-line silencers, floor/wall/ceiling inlet and outlet diffusers are available to complete the installation.

A Heat Recovery Ventilation System is Only as Good as the Ducting Used
Following years of experience in heat recovery systems, BPC Ventilation are now able to provide a range of 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.
Our Quiet-Vent Radial Semi Rigid Ducting Kits combine the performance benefits of rigid duct and the installation benefits of flexible duct. They work by treating each room individually with a dedicated 75mm duct run from two distribution boxes (manifolds), for supply and extract air at the heat recovery unit.
Quiet-Vent Semi Rigid Ducting Kits are the perfect choice for installing a MVHR Heat Recovery System as they provide huge performance benefits whilst dramatically reducing installation time

- Our Standard 75mm pipe is semi flexible, crushproof and with a smooth inner surface
- 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

The systems have been painstakingly 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 solid rigid ductwork.
All our radial ducting options are a system of individual smooth bore pipes which are crushproof, semi flexible with zero air loss. Our Premium ducting has an anti-static and antibacterial lining which individually connects each room to a distribution box (manifold).
The distribution box 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.
Our premium radial semi rigid ducting is available in both circular (75mm or 90mm) and oval (51mmx114mm) fittings.
Alternative Duct Options
As well as our radial ducting options, we can stock and supply Solid Rigid PVC, Galvanised Steel and Thermal EPP (foam) ducting if preferred.
