The PIV ONE positive input ventilation system provides fresh, high-quality filtered air; effectively dealing with condensation issues and diluting harmful pathogens. Installation is easy and it’s also incredibly cost-effective.
This advanced system operates continuously to maintain a fresh and healthy indoor environment. When the humidity threshold is detected, the fan automatically boosts its speed, effectively reducing excess moisture and preventing condensation build-up. This intelligent feature ensures optimal air quality, minimises the risk of mould and mildew growth and promotes a comfortable living space.

Features and Benefits
- Highly effective at reducing condensation and improving indoor air quality.
- Double filtration as standard, ensuring that the incoming air is clean, removing dust, pollen and external air pollutants.
- The external washable pre-filter features an integral magnet system to remove and clean easily (without the need for tools). This pre-filter stops dust from being pulled into the primary filter which would restrict filtration and reduce the filter’s lifetime.
- Internal ISO Coarse 60% (G4) filter as standard, removes dust, mould spores and general pollutants.
- For high-traffic areas, this can be upgraded to an IAQ filter to remove diesel fumes.
- Discreet ceiling diffuser with adjustable blanking plates allows the airflow to be directed as needed.
- Pre-wired, pre-mounted fixing points and multiple modes of operation selectable at the time of deployment mean a fast, versatile installation.
- Acoustic self-extinguishing foam lining for sound attenuation.
Specification
- Galvanised sheet steel casing, powder-coated in white (RAL 9010).
- Durable, solid ABS plastic top cover.
- The unit is designed for continuous running with a highly efficient EC motor which has integral thermal protection, is mounted on sealed-for-life ball bearings and anti-vibration supports.
- Forward curved centrifugal impeller is dynamically balanced and directly driven by the motor to provide a smooth airflow through the unit.
- The top cover is easily removable for inspection and maintenance.
