1、 Look at the brand

It's not that all the bag filters produced by big brand manufacturers are good, but at least their equipment meets the relevant national and industrial standards, and the after-sales service is relatively guaranteed.

2、 Look at the details

At present, there are many manufacturers specializing in the production of bag filters, but their quality is uneven. What is the reason? I think the main difference lies in two words - details. If the person in charge of the business, for all aspects of the production process must be constantly improving.

3、 Look at design

Good bag filter in the space design is also quite reasonable, there will be no waste of space, in the replacement of filter bags will also appear more humane, will also consider the convenience of operation and so on.

4、 Look at practical

We all know that the filter bag needs to be replaced frequently in the use of this equipment. If it is a better equipment, when the liquid enters it, it will have the function of automatic partial pressure. In this way, the impact on the filter bag is relatively small, which can effectively protect the filter bag, and the filtering effect is more stable.

5、 Look at the filter area

The size of the filter area determines the main performance of a device, so what are the factors that affect the size of the effective filter area?

1. Flow rate of medium: we can preliminarily determine the number of filter bags according to the flow rate of medium, the operating pressure and the normal flow rate measured by the corresponding precision and size of filter bags in water.

2. Pressure drop: according to the actual flow and medium viscosity of each filter bag, it can be judged whether the equipment exceeds the allowable pressure drop range.

3. Viscosity of medium: This is also an important factor to be accounted for, because the dirt or oil capacity of the filter bag can be calculated, and according to the replacement cycle of the filter bag, we can also judge whether it meets an operation cycle.
