Rensair units offer safe ventilation for schools Rensair portable hospital-grade air purification units, originally developed for Scandinavian hospitals, are now available from Core Air Conditioning Ireland for use in any space where clean and purified air is called for. They trap and destroy more than 99.97% of airborne particles such as allergens, bacteria and viruses, including the Coronavirus family, and use about the same amount of electricity as a modern kitchen fridge.
Rensair units can be used practically everywhere, from homes through to large and small offices, retail outlets, in hospitality, gymnasiums, beauty salons, educational facilities and public buildings. Being portable, installation is simple and siting locations are infinitely flexible. They are tailor-made for the Government’s guidelines on ventilation in schools which recommend the use of H13 HEPA filters and the safe use of UVC. Both of these technologies are incorporated into the Rensair units. A key advantage is that it takes only one person to set up a Rensair unit with no installation required. Just turn it on to start purifying the air. Operation is managed via controls on the machine or by using a remote. Wheel mounting makes it possible to manoeuvre the air
purifier between locations. The Rensair HEPA filter and enclosed UVC light have a 9,000-hour life, meaning the filter and light only need changing once a year, even if running 24 hours a day. The cost of replacing the H13 filter and UVC light (filter kit) is inexpensive and very simple and quick to do. Tested by independent laboratories, Rensair units clean up to 560m³ of air per hour, meaning one unit can clean a room of 230m² with normal ceiling height per hour. Using multiple Rensair units in larger spaces maintains the same air cleaning rate. The patented design and powerful fan create effective air circulation, ensuring that all air in a room is purified, as documented by the independent consultancy Norconsult. The powerful fan pushes pre-filtered air into the cylindrical-shaped HEPA filter

located in the middle of the unit. The fan creates high static air pressure in the cylinder, which pushes large volumes of air through the filter and distributes clean air at 360o. Safe maintenance The sturdy metal shell makes the Rensair air purifier robust and durable for years. Pre-filters capture dust and dirt and prolong the life of the H13 HEPA filter. Rendered safe by the UVC light, no specialist help is required when replacing the filter. Contact: Core Air Conditioning Ireland. T: 01 409 8912; E: info@coreac.ie; www.coreac.ie Q
