The control panel tells users when the filter needs changing. It’s set for a 2 – 12-month cycle, at run-time not lapsed-time, so it’s unaffected if the unit is switched off. Making it cheaper to replace than other filters on the market, yet just as effective
Supplied with the unit is a digital controller that can be used to pre-set the speeds to any required airflow within the performance range.
Boost can be achieved with a range of additional sensors or switches including momentary if used with a timer box
Although the Natural Air 180 is designed to work for continuous trouble-free operation, it can also be tailored to individual needs using the control panel. Energy can be conserved by switching to night-time mode and holiday mode, which employs trickle ventilation overnight, during holidays or when the property is vacant. The system can also be purged whenever required by using boost switching. Summer bypass control and the active humidity setting enable the unit to adjust to warmer temperatures or rising humidity. The system also performs diagnostics and displays advisory codes to help technicians maintain the unit.
Designed to help landlords and local authorities reduce damage to their properties through condensation and mould, the Natural Air 180 has an integral datalogger, recording its daily use. This provides instant information, showing whether the unit has been in use or a tenant has switched it off. This information is easy to access and can be taken directly from the unit whenever the owner visits the property.
Safe in the event of fire. - Automatic shutdown should fire alarm go off. Manual restart when alarm stops.
Integral Humidity Sensor
Unique, active humidistat reacts in real-time to gradual increases in humidity – perfect for even the smallest wet room. Flow rate is boosted only as needed, minimising energy costs and further reducing acoustic output. No more nuisance tripping as night-time temperatures drop. You set the humidity threshold to suit conditions – factory setting for boost is a 4% humidity rise in 5 minutes
Strong and compact EPP construction with a metal outer cover that allows for easy wall mounting in a wall cupboard or wall
The unit has 2 x low energy, high efficiency Constant volume EC motors (Ghost air technology)
The Natural Air 180 uses Intelligent Adapt flow Sensing to deliver constant volume performance. The motor is constantly assessing the performance of the impeller and, when there is a consistent change in airflow, brought about by reduced efficiency or by a strong wind applying back pressure, the motor adjusts the speed of the fan to maintain a constant volume of extracted air.
Installation is possible inside a 600mm wide kitchen cupboard
The Condensate drain is fitted to the bottom of the unit, we recommend that a flexible connection is fitted between the drain and overflow pipe
Electrical and control connections are made on the inside of unit
Dual condensate drains capture additional moisture generated in climate controlled buildings
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.

Xpelair N/A 180 using 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)

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
