Monodraught enhances its product range
Monodraught SunPipes are now offered with ceiling diffusers with white, brass, chrome or satin-finish stainless-steel effect trims — with both single- and double-glazed ceiling diffusers. Sunpipes are offered in 10 sizes from 230 to 1500 mm diameter. Monodraught has also added the Sola-Vent to its range of energy-free systems. Sola-Vent is a solar-driven extract fan, in two sizes and designs. They incorporate a 230 or 300 mm-diameter SunPipe to provide daylighting and solar-powered ventilation. Two integral batteries provide 8 h of backup operation, which is charged by a 600 x 300 mm photo-voltaic panel on the roof. Sola-Vents also incorporate two low-voltage halogen downlighters.
