GLF series urban comprehensive pipe gallery dedicated fan

Product category: Pipe gallery fan

Product Usage: Mainly used for ventilation and air exchange in urban comprehensive pipe corridors, as well as for smoke exhaust and air supply after accidents.

The GLF series urban comprehensive pipe gallery dedicated fan is jointly designed and developed by Zhejiang Zhefeng Technology Co., Ltd. and the Fluid Engineering Research Institute of Zhejiang University for urban comprehensive pipe galleries. It is mainly used for ventilation and ventilation of urban comprehensive pipe galleries, as well as for post accident smoke exhaust and air supplementation.

The GLF series urban comprehensive pipe gallery dedicated fans are mainly based on the length of the pipe gallery between 200 meters and 400 meters. In response to the special requirements of the urban comprehensive pipe gallery, they absorb and utilize advanced foreign technology, adopt isobaric meridian acceleration efficient impellers, and are developed as high-tech fan products. They have the characteristics of high wind pressure, low noise, wide efficient area, small size and easy installation. According to the requirements for fire smoke exhaust and explosion-proof ventilation in the pipe gallery, there are four types of dedicated fans for the pipe gallery: ordinary type, dual speed type, fire smoke exhaust type, and explosion-proof type.



1¡¢Product Features

¡ñ The GLF type pipe gallery dedicated fan is divided into single speed I type and double speed II type fans based on the characteristics of the ventilation conditions of the pipe gallery. According to the ventilation and ventilation requirements of different places, corresponding pipe gallery dedicated fans that meet the performance requirements can be selected¡£

¡ñThe XGLF type pipe gallery fire and smoke exhaust dedicated fan can operate continuously for more than 60 minutes under high temperature conditions of medium temperature of 300 ¡æ, meeting the smoke exhaust requirements after pipe gallery fires.

¡ñThe BGLX type explosion-proof special fan for pipe racks is strictly produced in accordance with the national standards GB3836.1-2000 and GB3836.2-2000, with explosion-proof levels of dIIBT4 and dIICT4. The product has obtained explosion-proof qualification certificates and explosion-proof electrical national industrial product production licenses, which can meet the safety ventilation requirements for explosion-proof locations in pipe racks.

¡ñInstallation method: It can be installed horizontally, vertically, or rooftop.

¡ñ The external dimensions and performance parameters of the supply fan and exhaust fan are consistent.
