Are bag filters washable?

Which bag filters can be washable?

In fact, bag filters can be washable, but not all bag filters can be washable. It is only recommended to clean nylon mesh bag filters and metal stainless steel mesh bag filters. NMO nylon bag filter is made of non-deformable nylon spinning and spun into a mesh according to the specified specifications. After heat setting, it becomes a monofilament mesh; It is characterized by high strength and will not be deformed due to pressure changes. The monofilament weaving forms a smooth surface, which is easy to clean and can be used repeatedly. It is also suitable for filtering some liquids with high impurity content, thus reducing the filtering cost.

Other polypropylene, polyester fiber and other bag filters belong to multi-layer fiber structure, which will lead to fiber shedding during cleaning and scrubbing, thus affecting the filtering accuracy and efficiency. Therefore, PP, PE and other needle felt bag filters are generally not used for cleaning.

How to wash the bag filters?

The nylon mesh bag filter and metal mesh bag filter will not fall off due to their properties. The liquid bag filter can be washable with clean filter stock solution, or with clean water without affecting the product quality. However, attention should be paid to the cleaning method. It is not allowed to directly wash with a high pressure tap, and it is also prohibited to flush with a tap aimed at a certain point for several seconds. At the same time, it is also strict to brush with a brush. You need to turn the bag filter over from the inside to the outside, and then soak it in the cleaning solution for 10 minutes, and then gently scrub it. Do not scrub it too hard, and repeat it for two to three times.
