Brochure - Envirovent

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.

The ENV 100 12V models are available in a
variety of fan functions to include standard,
timer and humidity sensor options. Using the
CT-45/12 transformer the fan provides total
safety within the spray area of a shower or
bath to be installed over or within Zone 1. The
transformer must be located out of the reach
of any water spray or person using a bath or
shower.
