The performance indicators of the air filter of the air compressor mainly include dust removal efficiency, resistance, and the dust capacity of the filter. The definition of dust removal efficiency is the percentage of dust captured by the filter to the total dust brought into the filter by gas, usually expressed as r/.
Namely=(G2/G1) × In the 100% formula: G1: - dust volume with human filter per unit time, g/h; G2: - The amount of dust captured by the filter per unit time, g/h.
The dust removal efficiency varies depending on the diameter of the dust particles. When measuring the dust removal ability of a filter, the particle size must be specified. Comparing under the same particle size is the classification efficiency. Resistance refers to the pressure drop of gas through a filter, which is as small as possible while ensuring filtration accuracy. As the resistance of the filter gradually increases, it will affect the inlet pressure of the air compressor, causing an increase in energy consumption of the air compressor; When the resistance is too high, it can also cause the air compressor to surge. Therefore, when the resistance of the filter reaches or approaches the allowable vacuum pressure of the air compressor, it is necessary to replace the filter material in a timely manner. The dust capacity of the filter material represents the amount of dust captured by the filter per unit area from the time the filter material starts working to the time when the filter material needs to be replaced, expressed in g/m2. This indicator reflects the consumption of filtering materials and the production cost of filters.
Replacing the filter in a timely manner can greatly improve work efficiency and save a lot of time for oneself. You can do other things instead of saving money for a while, which can lead to serious consequences and regret it too late.
