The fan is also called unloader, air lock valve and rotary valve. It is one of Tianlan's environmental protection products. The fan is mainly divided into three types: ordinary type, pressure-resistant type and high temperature resistant type. What are the characteristics of the fan? Today, Tianlan environmental protection tells you:

1. The elastic impeller is used to close the fan, and the flexible seal is enhanced to eliminate the impeller sticking phenomenon.

2. Turn off the bearing seat of the fan and move to the outside of the valve body to isolate the direct source of dust particles, prolong the service life of the bearing and facilitate maintenance.

3. The closed fan is equipped with cycloid gear reducer, which has reliable structure, stable and compact.

4. The fan is beautiful and easy to use.

5. Turn off the fan, smooth operation, low noise.

6. Since the bearing and gear box of the fan are far away from the shell, the high temperature and lubrication are greatly improved.
