We are delighted to offer this unit with a free three year guarantee - giving you an additional year\'s peace of mind on top of Xpelair\'s standard two year guarantee. This Xpelair RX6 model is a neat way of ventilating through glazed and solid roofs and can be used vertically in windows on exposed sites such as coastal areas and high rise buildings. The commercial duty roof fans are particularly suitable for pubs, restaurants, offices, kitchens, factories, and squash courts, schools in areas like changing rooms, and kiln rooms and a wide range of shops. This contoured high gloss white housing is sleekly styled. For safety, a finger guard is integrated into the ultra slim high gloss ABS fascia. The UV stabilised roof cowl assembly is a generous size to provide weather protection at all angles. They are suitable for single and sealed double glazed windows and panels up to 25mm. Installation in wire cast and sealed double glazed roof lights is rapid using Xpelair\'s unique metal ladderstrip and screw system ensuring a secure and weather-tight optional roof mounting plate allows this model to be fitted to dressed curbs.
