Shandong Teng Yu FRP exhaust fan Ltd, production of fire smoke the wind, two-speed exhaust fan, fan production centers. 
 1, the exhaust fan with excellent performance, good high temperature performance, high efficiency, an area less than the centrifugal fan, and convenient installation. 
 2, the exhaust fan by the special "national fixed fire extinguishing systems and fire-resistant component quality inspection center" of qualified, the performance of the leading domestic level. 
 3, excellent high temperature performance: the fan tested in accordance with GA211-1999 Fire Code standards, establish higher standards of corporate internal control to ensure that the system can be at 300 ℃ high temperature more than 60 minutes of continuous operation, 100 ℃ temperature conditions for 20 hour / time is not damaged, is widely used in high-level civil construction, oven, underground garage, tunnels and so on; 
 4, for a wide range: according to the different requirements of senior civil, or multi-speed with variable speed drive form, in order to achieve one machine (that is commonly used when high temperature and fire through the exhaust smoke) purpose; leaf divided into shaft flow (GP (HTF) - Ⅰ, Ⅱ) and oblique flow (GP (HTF) - Ⅲ, Ⅳ), so fans of the series has a wide range of performance parameters. If the user requirements of the noise is high, can be made into a silencer-type fan. 
 5, high efficiency: The Series fans by using advanced CAD software developed multi-objective optimization design of new products, the measured efficiency of greater than 80% of that fan, part of the large number of machines greater than 85%, and the characteristics of a flat efficiency curve conducive to energy conservation; 
 6, easy installation, an area less than the centrifugal fan: The fan base in the form of oblique axial-flow fan or fans, can be directly connected with the duct or wall installation, the installation can be vertical or horizontal form. Area to save a large extent
