2LG820 Three Phase 380V Double Stage Ring Blower for Dental Equipment
Product introduction
The working principle of the double stage ring blower is based on regenerative airflow. Air enters the first stage, where the high speed impeller accelerates and pressurizes it. The airflow then passes into the second stage for further compression. This twostep pressurization greatly increases output pressure while maintaining stable airflow. Since there is no contact between moving parts, the blower operates without oil, ensuring clean air delivery and low maintenance. Key features of the doublestage ring blower include high pressure performance, reliable continuous operation, low noise, compact structure, and strong durability. It supports both positive pressure blowing and negative pressure suction, making it extremely flexible. Common protections such as IP55 insulation and thermal overload protection ensure safe operation in harsh industrial environments. Jiangxi Sop Industrial Co., Ltd. is professional blower's supplier in China and we have established partnerships with 5000+ clients from all over the world. We can offer ODM & OEM and 7 days fast shipping services.
