Product Details
Maintaining air purity is essential in food-grade and chemical processing, making the Industrial Oil Free Two Stage Ring Blower the premier choice for contamination-free air handling. By utilizing a regenerative side-channel principle where the impellers never make contact with the pump casing, this machine ensures that the output is entirely free of lubricant mist. The Industrial Oil Free Two Stage Ring Blower uses two series-mounted rotors to multiply internal air acceleration, achieving discharge pressures as high as 620 mbar and vacuum suction down to -450 mbar, perfect for high-speed carton filling and deep-tank agitation.
The performance of the Industrial Oil Free Two Stage Ring Blower is anchored by its 100% all-copper coil motor, which offers superior thermal endurance compared to aluminum alternatives. Rotation is managed by world-class C&U bearings with full-seal rubber rings, rated for 180°C high-temperature stability. The aviation aluminum housing features deep radial fins for rapid heat dissipation, ensuring the blower stays within safe operating limits during 24/7 industrial duty. Every unit is manufactured at our integrated Taizhou plant and undergoes individual QC certification. Choosing this oil-free blower provides a reliable and hygienic pneumatic solution backed by Yijia's years of engineering experience and export reach to over 60 countries.

Application scenarios introduction
Protecting our environment requires robust air handling for waste decomposition. Our regenerative blowers provide "oxygen supply in water" for municipal wastewater aeration pools, supporting the biological treatment process. In "biogas digesters," the blower is used for gas circulation and methane agitation, preventing the formation of stagnant crusts and maximizing gas production. The suction side is utilized for "smoke blowing and suction" of hazardous fumes from processing tanks, moving them into "gas decomposition" devices for neutralization. With an aviation-grade aluminum housing and professional wiring glands, our blowers provide a durable safety solution for the aggressive gases and flammable atmospheres common in environmental engineering.
