Bell fan

The bell mouth fan adopts a novel and reasonable bell mouth design, which can gather the air volume and concentrated wind direction, and the air volume is larger, which is more energy-saving and noise-reducing. The outer frame material is made of automatic zinc alloy sheet, and the thickness of the zinc layer per square meter is 275 grams. The louver is made of 275 g square meters of high-zinc plate material, 06 mm thick, easy to install and disassemble. The fan blade is made of 430#/304# /NSDCC sheet, and the balance is tested. The air volume is large. Low noise, no shape, no break.
1. The wind resistance is small, the sealing is good, and the efficiency is high.
2. Add a rubber sealing device when the bell blower is closed. Depending on the environment, when multiple fans are started at different times, the return air can be effectively avoided and the operating efficiency is greatly improved. Compared with the same power fan, the efficiency can be increased by 15-20%.

3, the fan uses stainless steel fan blades, large air volume, no deformation, continuous cracking, beautiful and durable. (The original use of aluminum alloy fan blades, due to the long-term low fatigue strength of aluminum alloy materials, fracture, cracking, small air volume and other issues.)
4. The fan blades are calibrated by computer dynamic balance instrument to ensure smooth operation of the fan, reduce noise, enhance stability and extend service life.
5. The belt adopts B-type belt and has a long service life.
Hot-dip galvanized columns and protective nets are used to ensure no rust during future use, and standard parts are used to prevent rust.
The quality of the bell mouth fan produced by Qingdao Montexinfeng Technology Co., Ltd. is relatively good and the price is reasonable. Welcome new and old customers to come to visit and negotiate and cooperate.

All values are derived from a 3-phase 50 Hz single-speed motor Note: The air volume parameter is measured in a standard environment (20 ° C, 1,013 HPA)
