Vent Axia Integra
The Integra heat recovery unit has been specially designed to provide ventilation for flats or rooms in residential, commercial, educational or leisure applications. Balanced ventilation is achieved by using nominal 100mm diameter rigid ducting.
Using a high performance, polymeric heat exchange cube, together with two powerful fans, the Vent-Axia Integra achieves efficiency of up to 70%.
The compact cube interleaves outgoing moist air with incoming fresh air, allowing the heat from one to warm the other without the two air streams mixing. Energy is saved on room heating, with no power being used by the cube itself.

The normal unit has two speeds of Boost/Trickle ventilation when used with humidity sensors or a manual wall switch. 95 x 225 x 75mm (H x W x D)
An optional 150VA Surface Mounting Transformer is available with six voltage selections for trickle settings to match dwelling volume.
The enclosure is constructed of powder coated galvanised metal
The unit has 2 x low energy, high efficiency D/C fan motors
The Vent-Axia Integra is designed for mounting in ceiling voids, lofts or above a suspended ceiling. Four 100mm spigots are provided for simple connection to insulated flexible or rigid ventilation ducting. The unit comes complete with a 22mm condensate outlet situated on the base of the unit, this should be connected to a suitable outlet for condensate drainage.
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.

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
A 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
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)
Design and Supply
As leading heat recovery specialists our in-house designers can provide a comprehensive and bespoke design backed up with our technical experts that can answer any queries you may have,
Free delivery is included to any mainland UK or ROI address with this kit and with thousands of products in stock we are one of the few specialists that can provide quick or priority dispatch to any location using professional logistics companies, we are able to deliver to any other location on request,
If required all products in the kits can be changed or altered to suit your specific needs before dispatch and if you do require extra materials we will supply these to you at the same highly discounted rates,
Any products not required can be returned for a refund (excluding return delivery cost)
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.
