2LG920 High Airflow Double Stage Side Channel Blower for Printing Machinery

This double stage side channel blower is engineered with two series-connected side channel impellers mounted on the same high-torque motor shaft, transferring kinetic energy to air twice in sequence to achieve far higher differential pressure and vacuum performance than single-stage models of the same size. Its full die-cast aluminum housing and precision-balanced impellers eliminate internal friction during operation, delivering 100% oil-free, contamination-free airflow that meets strict industrial clean air requirements. The integrated double-layer sealing structure effectively prevents air leakage, ensuring stable pressure output even under long-duration full-load working conditions.

    Product introduction

    Designed for high-demand industrial continuous operation, this double stage side channel blower features a compact, integrated unit structure that removes the need for extra connecting pipes between the two compression stages, greatly reducing installation space and airflow loss. Equipped with dual inlet and outlet mufflers and a dynamically calibrated base, it operates at a remarkably low noise level with minimal vibration, no need for additional shock-absorbing measures in most regular installation scenarios. Its maintenance-free main structure only requires occasional bearing lubrication, supportin non-stop reliable operation. 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.

    Application

    This double stage side channel blower is perfectly suited for scenarios that demand higher pressure or vacuum than ordinary single-stage blowers can provide. It delivers stable performance for deep water wastewater aeration, high-lift pneumatic conveying of granular and powdery materials, and high-vacuum suction for industrial CNC adsorption systems. It also serves as a reliable oil-free air source for industrial drying lines, vacuum packaging machines, aquaculture deep-water oxygen supply, and high-efficiency industrial dust extraction systems, making it a go-to workhorse for heavy-duty industrial applications.
