The ENV range of centrifugal fans are suitable for many general domestic applications where higher system resistances are encountered. The range comprises of two 100mm models, the 100 and 250, each available with a variety of fan function options and suitable for wall, ceiling and ducted applications. With automatic backdraught shutters fitted as standard, this prevents air entry and limits heat leakage when the extract fan is not operating. Supplied with double electrical insulation, standard and timer models are IPX4 rated and humidity sensor models are IPX2.
