CUR 7001 BKIT In Line Version - Standard CUR 7003 BKIT In Line Version - Timer SPECIFICATION & INSTALLATION OVERVIEW. The silavent Curzon range of fans are ideal for bathrooms and toilets where longer duct runs are required. Made from high gloss ABS, these fans produce an impressive pressure performance required to extract air along longer ducting runs and are capable of extracting up to 80m3/h. Easy to install, the Curzon fans are built to the highest quality with the motor mounted on rubber bushes for quietness and long life.

4 This range of fans is designed for wall or ceiling fixing and for use with all silavent 100mm duct and flatduct. It can also be used in conjunction with an integral fire shutter back plate which is rated to 1 hour (FLA501A). The pull cord model is not suitable for ceiling mounting. The humidistat versions are now fitted with the new Intelligent electronic humidity controls which work as intelligent humidistat. Unlike traditional humidity controls which trigger when humidity reaches a pre-set level, the Intelligent board reacts to a significant rate of change in a location's humidity level - See Mayfair Range for full explanation of how Intelligent controls operate. The in-line versions of the CURZON are designed to provide a powerful CENTRIFUGAL fan to fit out of sight within the roof area. Giving the same performance as the surface mounted version, this model is ideal for use with the silavent SPOTVENT.
