In general, the ring blower has the following characteristics:
1. The utility model has the functions of blowing and sucking, and can be used for both suction and blowing.
2. Running with or without oil, the output air is clean.
3. Compared with centrifugal fan and medium-pressure fan, its pressure is much higher, often more than ten times of centrifugal fan.
4. If the pump body is die-cast as a whole and the shockproof mounting pedestal is used, the requirement for the mounting foundation is very low. It can even operate normally without the fixed pedestal, which is very convenient and saves installation cost and installation cycle.
5. Comparing with similar fans, the noise of their operation is lower. The ultra-silent high-pressure fan is introduced.
6. Maintenance-free use; its wear-and-tear parts are only two bearings, which do not need maintenance basically within the warranty period;
7. The mechanical wear of high-pressure fan is very small, because there are no other mechanical contact parts except bearings, so the service life of high-pressure fan is of course very long, as long as it is in normal use conditions, 3-5 years is totally no problem;
