The Fresh 99H humidity-sensitive, through wall ventilator is designed to introduce fresh air into properties. It opens and closes automatically depending on relative humidity (RH), reducing the potential for harmful condensation and heat loss. With an operating range of 35-75% RH, the vent includes a trickle facility even when ‘closed’ to ensure the constant ingress of fresh air. Being non-electrical it requires no energy to operate. It is easy to fit and virtually maintenance free.
An acoustic humidity-sensitive option, the Fresh 99HdB, provides sound reduction up to 40dB Dn,e,w and is suitable for use where there are high levels of external noise such as near main roads, airports or railway lines.
Both products offer improved ventilation equivalent areas compared to previous models.
