Loft Mounted PIV

AXCO Positive Input Ventilation (PIV) Systems for New & Existing Homes 

Whether your home is a townhouse, semi-detached, detached property or even an apartment, we have a wall mounted or loft mounted Positive Input Ventilation System specific for your requirements.

The loft mounted unit takes maximum advantage of the benefits of solar gain from within the loft space – the natural accumulation of heat from the sun on bright days.
Temperatures in the loft space are on average 3°C higher than outside, and as the loft mounted unit draws fresh air from the loft and delivers it into the property, this results in a relative saving of around 150 watts of heat energy per day in an average modern family home.

Why AXCO?

  • Integral-pre heater designed to temper the incoming air during periods of low external temperatures to prevent the air falling below 10°
  • Hours run metre monitors operational life and verification of usage.  Retains memory in the event of a power failure and restarts at existing reading when power is restored
  • Superior longlife filter – 5 years maintenance free (apart from a filter change after 24-36months)
  • Synthetic fibre based filter made to G4 standard to enable the removal of a high proportion of airborne particles, such as pollens.  Filter conforms to all European Union and US fire classification standards
  • Both wall mounted and loft mounted units are designed, built and tested to the following standards;
    • BBA Certificate No: 03/4043
    • CE EMC Compliance: EEC/89/336
    • Low Voltage Directive: IEC 72/73/EEC

Wall Mounted PIV

AXCO Positive Input Ventilation Systems for New & Existing Homes

Whether your home is a townhouse, semi-detached, detached property or even an apartment, we have a wall mounted or loft mounted Positive Input Ventilation System specific for your requirements. 

Suitable for apartments/flats, the wall mounted unit is designed to draw fresh air from outside through a filtered power unit which is then ducted to a central location in the property.  This displaces the moisture-laden air, which lowers humidity levels, whilst forcing contaminants out of the property through natural cracks and leakages.  Indoor air quality is improved, preventing condensation and eliminating mould growth.

Air Source PIV System

Air Source PIV

AXCO Positive Input Ventilation Air Source for New & Existing Homes

Going beyond traditional input ventilation, the PIV Air Source has the facility to source cooler air from outside the building when the temperature in the loft space rises above 25°C. Detecting the rise in temperature, the unit starts to draw air from atmosphere via a temperature controlled diverter mechanism. This not only provides efficient perception cooling into the property during warmer weather, but also maintains the required level of ventilation continuously throughout the year. This facility is greatly beneficial for properties affected by high levels of Radon.

By drawing in fresh, filtered and clean air from outside, the units gently ventilate the home from a central position on a landing in a house or the central hallway in a flat or bungalow.

Moisture laden air is diluted, displaced and replaced to control humidity levels around 55%. This significantly reduces or eliminates surface condensation, the main cause for mould growth. With lower humidity levels, dust mite populations are also substantially reduced to provide a significant improvement in the health of asthma sufferers and general indoor air quality
