4RB ring blower product core function and industry application value

The 4RB annular blower is a vacuum aeration equipment specially designed for wastewater treatment in food processing plants, and its core function is to achieve efficient aeration and water agitation through high-pressure air flow. The model adopts multi-stage centrifugal compression technology, the impeller is composed of 41 precision parts, and through the synergistic effect of ADC12 high-strength die-cast aluminum casing and impeller, it can stably output 360mbar vacuum negative pressure in the pressure range of 0.03-0.15MPa, which can meet the needs of high organic matter concentration and high suspended solids content in food wastewater treatment. Its two-stage structure design makes the air volume reach 165m³/h, which is more than 30% higher than the traditional single-stage fan, especially suitable for scenarios with large aeration tank depth or frequent backwashing.

In the food processing industry, the performance advantages of this model have been verified through cases such as aquatic product processing and dairy wastewater treatment. For example, a dairy plant introduced this model to increase aeration efficiency by 25% while reducing energy consumption by 18%. Its built-in silencing pipe and shockproof foot seat design control the operating noise below 65dB, which meets the strict requirements of environmental noise in the food workshop. In addition, the front layout of the bearing and the sheet heat dissipation structure effectively extend the life of the equipment, and the imported high-speed bearing can achieve 150,000 hours of maintenance-free, significantly reducing the cost of downtime and maintenance.
