The original fan vibrates heavily and requires anchor bolts, has high noise, requires water cooling, has a high failure rate and is inconvenient to maintain; it does not have a frequency conversion function to adjust the flow rate, and consumes a lot of electricity;

 

DECENT multi-stage centrifugal fans have high efficiency, low noise, no water cooling, no anchor bolts, high efficiency and energy saving, saving more than 20% energy for users; the fan life span is more than 15 years, and the economic benefits are considerable.
