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. Features Benefits • Neon light • Powerful forward curved centrifugal impellers • Automatic backdraught shutter as standard • Variety of fan function options • SELV model available • Two year guarantee • Compact • Quiet operation • Front cover clips off to access impeller for easy cleaning • Meets building regulations Internal Humidity Sensor Adjustable Run-On Timer Internal humidity sensor which automatically switches on the unit when the relative humidity rises above the selected set level (adjustable between 65% and 90% RH.) Adjustable electronic run-on timer set between 5 to 25 minutes.

Installation Full installation guide is enclosed with all products; or sent separately in advance - if required. ENV 250 Is a 230V 50Hz A/C shaded pole motor with self-resetting Thermal Overload Protection as standard. Fan The impeller is a powerful forward curved centrifugal fan to deliver high performance against high static pressure resistance with minimum noise generation. All models are fitted as standard with a backdraught shutter located in the fan exhaust spigot. Servicing / Maintenance The extract fans only require periodical cleaning using a cloth impregnated with a soft detergent. Static Pressure (Pa) 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. Motor Guarantee Is covered by a 2 year warranty subject to the specified maintenance.
