Aunason Environmental Protection is a domestic company that makes dust collector equipment. Committed to passing the environmental impact assessment of enterprises.

Dust collector equipment.

The dust removal efficiency is high, generally more than 99%, and the dust concentration of the outlet gas of the dust collector is within tens of mg m3, which has a high classification efficiency for fine dust with sub-micron particle size.

The range of air volume is wide, the small one is only 1 min m3, and the large one can reach 1 min tens of thousands of m3, which can be used for flue gas dust removal in industrial furnaces and kilns to reduce the emission of air pollutants.

The structure is simple, and the maintenance and operation are convenient.

On the premise of ensuring the same high dust removal efficiency, the cost is lower than that of electrostatic precipitators.

When using high-temperature resistant filter materials such as glass fiber, PTFE, P84, etc., it can operate under the condition of more than 200 high temperatures.

It is not sensitive to the characteristics of dust, and is not affected by dust and resistance.

Personal suggestion: In this regard, I suggest you look for manufacturers in the Kunshan area, Aunason Environmental Protection Company focuses on waste gas treatment and provides one-stop solutions, you can consider it.
