For a natural or hybrid ventilation solution in schools and other educational facilities Passivent can provide design expertise and technical support acquired over 38 years of business. Its products are designed to improve indoor air quality, thermal comfort and occupant wellbeing. Some of the company’s products also attenuate noise.
Passivent’s Aircool® range of wall and window ventilators are virtually silent in operation and provide controlled air intake and extract in natural (and mechanical) ventilation systems, with superior thermal performance when closed. They are also available as thermal and acoustic variants which temper incoming cool air or attenuate noise.
A hybrid mixing variant of the Aircool® – the Hybrid Plus2 Aircool® – can be used in classrooms, as part of a single-sided ventilation strategy. Meeting the requirements of Building Bulletin 93 (Acoustic design) and Building Bulletin 101 (Ventilation and IAQ) it has different operational modes, dependent on the internal and external environment, and sensors which respond automatically to increases in temperature and CO2. A boost function also maximises fresh air supply. This quiet, energy-efficient system is controlled by the Passivent iC8000 controller allowing for up to 40 individual zones to be managed.
Passivent’s SoundScoop® – an acoustic ‘room to room’ air transfer unit – can be used between internal spaces of a building to attenuate noise and enable crossflow ventilation. These patented units work well in conjunction with Passivent’s standard, thermal and acoustic Aircools providing sound reduction between noisy and quiet areas, and also providing speech privacy.
Passivent’s range of roof ventilation terminals, such as the Airscoop® and Airstract®, are ideal for larger spaces such as sports halls and atriums. They offer Class A 100% certified rain rejection (to BS EN 13030:2001) so that a building can be fully ventilated regardless of weather conditions. Available in a range of designs and sizes to suit a building’s aesthetics and ventilation requirements, they can also be colour-matched to any RAL or BS colour. With excellent thermal and airtightness performance when closed Passivent’s terminals can also be controlled by Passivent’s iC8000 controller.
