Similar to the standard GFRP ones, this kind of upstands can be made in the dimensions shown in the tables alongside, with a height of 50 cm.
GFRP monobloc upstands with extractors are particularly suitable for spaces where continuous ventilation, both natural or powered, is required in order to get an air exchange without the use of traditional openings.
The extractor is tangential, with a 240 m3/h flow rate and a shielded single-phase motor (230 V, 37 W) able to operate with temperatures from -30°C to +50°C.
The air flow is protected by an anti-insect net.
