The leakage rate of the wind gate in the whole closed state is less than 3%; High working pressure is less than 50kpa; High working temperature 400 ℃ or less.

The main properties and features of the round wind door:

1. Applicable to coal, smoke, dust, air and other media; Working temperature of 450 ℃ or less

2. The DD41 series of round wind doors have the common type and wear-resisting type to be used by users to guarantee the requirements of different working conditions and improve the service life of the wind doors.
