Heating & Ventilation Energy efficient Environmentally friendly Economical Residential Ventilation with EC motors The range of residential ventilation products developed by Vectaire Ltd is one of the most comprehensive available. They are designed to remove moisture, odours and pollutants whilst meeting all the latest requirements for energy efficiency, environmental friendliness and economy. And, the comfort of the residents is vital - is it too damp, too dry, too hot, too cold, too draughty etc? Vectaire products combine well thought-out, efficient ventilation, low noise levels and running costs with excellent SFP ratings. Vectaire’s low energy products with EC motors are manufactured (mostly in the UK to ISO9001) using the latest technologies to ensure correct ventilation rates. They comply with Building Regulations for dwellings - Part L1 2010 and Part F2010 (England and Wales), Section 6 (Scotland) and Part K (Northern Ireland) (WHHR Mini DC is Part L2 2010. Products have been tested (by BRE) to confirm specific fan power performance and heat exchange efficiency. A continuous mechanical extract system is the ideal way to ventilate. It provides low level extraction, maintains a constant trickle of fresh air, reduces dangerous pollutants and removes moisture and odours. Buildings can be ventilated with individual fans in each room (d-MEV), centralised systems (MEV) and centralised systems with heat recovery (MVHR). Several rooms can be continuously and simultaneously ventilated to provide new, filtered air. When the product incorporates a heat exchange unit the loss of expensive heat is restricted, ensuring efficiency and economy in combination with a low carbon footprint. Products include WHHR’s (Whole House Heat Recovery units) designed for inline or upright installation, and ranging from small in-line units designed for one/two roomed apartments (ie student accommodation, hotel rooms, extra care facilities etc), to units for areas of up to 230m2, recovering up to 94% of the heat, and with specific fan powers from 0.40 w/l/sec. Models have several control options including summer bypass and integral humidstat. All have a variable choice of trickle speed and boost options, often with delay-on timers and integral frost-stats. An ultra low profile model - only 200mm deep - is for use where space is at a premium. Also for restricted space is the in-line Microbox (MEV). This requires only one discharge grille and it is available with both round and rectangular spigots. Two models (axial or centrifugal with energy efficient EC motors) are available for single room extraction. They operate continuously, almost silently and very economically in any wet room
