Catalog excerpts

GEOVENT centrifugal fan LSFG and MSFG with forward curving impeller is used for extraction within the industry or for comfort ventilation, depending on the variant. The fan is made of 100% galvanized steel for optimum corrosion resistance and therefore, it is suitable for outdoor installation on the roof or on the wall. There is a complete program of accessories, and the fan can be delivered with a number of options, such as flex connection, mountings, rainshield, motor protection, pressure monitor and soundproof box. As standard we supply supporting angels with vibration absorbers, inlet nozzle with net and clamp for mounting the outlet flange. The fan is also supplied in ATEX version according to the 2014/34/EU directive. Then the type is called LSX/ MSX, and it is supplied as standard with EExE motor. Other variants are offered on inquiry. On inquiry it is possible to deliver the fan with built-in frequency converter, two-speed motor, with 6- or 8-poled motors, motors with special voltage or higher efficiency, special high temperature version a.s.o. Air volume up to: 4.900 m3/h Technical data / Other data / Features Motor: Directly driven by a 85-Flange motor. Sealing class IP-55 Voltage: 3x400V or 1x230V / 50 Hz 3 of the fans sides can be used as mounting flange. Made of hot-galvanized plate. All screws and bolts are electro galvanized. Inclusive supporting angels with vibration absorbers, inlet nozzle with net and clamp for mounting the outlet flange.

LSFG/MSFG 146 - 250 - LSX/MSX ATEX versions Pressure drop - LSFG/LSX Pressure drop - MSFG/MSX The fans ampere usage is based on 3x400V motors. When 1x230V motors (Fan sizes 146-225) are used, is it possible to use a factor on about 2.7 to get the approximate ampere usage (can vary depending on model) The air measurements are made without using an outlet flange on the outlet side and by a temperature on 20°C. The pressure lost measured in Pascal indicate the static pressure. The fans ampere usage is based on 3x400V motors. When 1x230V motors (Fan sizes 146-200) are used, is it possible to...

Our series of atex fans with forward curving impeller are as standard supplied with EEx e motors, but can also be supplied with EEx d or EEx de motors. The typical scope of application is zone 1, zone 2 and zone 22. The construction is based on standard LSFG/MSFG, but has beside the ATEX motor, also protection against static and sparks in inlet. For ATEX applications, where acid proof execution is needed, this can be offered. All plate parts, screws and bolts a.s.o. are supplied in rustproof ANSI 316L and are subsequently stained. The wheel is either supplied in a special lacquered edition...
