2 x G3

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.
