Using the Vent-Axia LoWatt range can reduce electrical consumption, thus reducing the overall carbon footprint.

When using heat recovery ventilation, the heating system requirement is reduced thus potentially saving another 500kg of carbon per annum.

Overview
Air Minder is the next generation of wholehouse heat recovery ventilation systems. It will effortlessly remove your home’s polluted air and provide a constant supply of clean filtered air, allowing you and your family to live in an ideal indoor environment. They are installer friendly and fit into many different orientations with their unique ducting turrets rotating to any required angle.

Air Minder is available in two unit sizes, 290 or 400 versions. Air Minder can be installed in lofts, either on the rafters or suspended, or in ceiling voids, large cupboards or basements.

Air Minder combines continuous ventilation with the most advanced heat recovery system available. Sized correctly it will gently ventilate the property at a rate of about half an air change per hour, removing moist air and unpleasant smells from the kitchen, bathrooms and toilets and extracting it to the outside. Fresh filtered air is drawn into living spaces such as bedrooms and living rooms, providing continuous ventilation even when the house is sealed up for the day.

By keeping humidity levels low and introducing warmed fresh filtered air to replace contaminated air, the quality of the internal environment is significantly improved. Continuous wholehouse ventilation can help reduce relative humidity to below 70% RH, which inhibits the ideal living and breeding conditions of the house dust mite.

For hotter climates, FB models are fitted with a summer by-pass feature which automatically opens to maintain comfort conditions.

Built-in EU3 filters are easily removed from the unit. For less accessible applications or for higher levels of filtration, a separate ceiling mounted EU7 bag filter cassette is available.

Performance
Constant velocity DC motors in the unit ensure that balancing the input and output air volumes is done automatically. Air Minder has a choice of performance settings based on volume of the home and can be boosted to a higher ventilation rate either manually or using remote sensors such as the Vent-Axia Indoor Air Quality Sensor, humidity sensors etc.

Easy Installation
Air Minder is the ultimate in heat recovery brought together in a brilliant ABS and foam composite design. It's simple clip-together modular construction allows Air Minder to be quickly and easily installed horizontally or vertically. Once installed the user has complete control over the Air Minder system.

Once the lightweight base section is in place, the cell, turrets and top section are simply clipped into position to complete the installation.

The unique circular turrets rotate through 270°, which give the option of connecting straight onto a duct from any angle without creating resistance or reducing airflow.

Air Minder comes complete with a unique LCD control programmer and 15m of signal cable, allowing the controller to be mounted in a convenient central area. There are no batteries and in the event of a power cut the control programme will be retained.

Electrical connection couldn't be simpler, once the cover is removed from the electrical control box, both motor cables are secured by cable clamps and plugged straight onto the PCB. The mains connections are already marked and fast clamp connections are used for the DC controller cable.

Controller
DC Control Programmer - surface controller with LCD status screen. Automatically switches between 3 speeds, slow (night), medium (day) and manual boost.Supplied with each Air Minder unit.

• User programmable or default program • On/Off/Boost and Sensor mode operation • Time elapse meter (hours unit has run) • Auto Summer by-pass (when fitted) • Auto defrost • Filter cleaning indicator • Heating failure cut-out • Service indicator

Cleaning & Maintenance
Cleaning intervals depend largely upon the location. Air filters and air supply and extract grilles will generally need to be cleaned at least two or three times a year: and the heat exchanger in the Air Minder unit annually. Fan impellers can be inspected, and cleaned if necessary, when the heat exchanger is cleaned.

• Please refer to the Air Minder Userguide for full details.
