Advantageous features of volume 1. Turn the rotary fan small fan, air volume, low noise, energy province (rotary blowers uses the principle of rotating air fan operation, though small in size, but large air volume, energy saving, quiet operation is otherwise . The fans can not compare 2. Anti load change, stable air volume (for example: wastewater treatment aeration tank pressure changes, the load changes, but the wind has changed little with the pressure change) 3. Turn the fan maintenance is simple, less failure. long life (low speed, wear, long life) HCC-20S rotary fan (fan slide, swing fan) features: 1, with the air chamber, bulk gas smooth (All models with air chamber to prevent air pulsation, smooth diffuser.) 2, material well, clever structure, performance (blowers all use of quality materials, compact structure, durable rotating fan outlets, high performance, long-term use of a small fault.) 3, simple maintenance, fault , long life (low-speed rotation of the fan where the cheapest, low wear, long life.) 4, rotating fans have a variety of models, a variety of speed, the fan choice, can be customized according to user needs processing.
