There are 3 ways of air filtration: inertia, filtration and oil bath.
Inertial formula: as the density of the impurity is larger than the air, when the impurity rotates or turns sharply with the air, the effect of centrifugal force can separate the impurity from the air flow.
Filtration: guiding the air through the metal filter or filter paper, blocking impurities and adhering to the filter element.
(3) oil bath: the bottom of the air filter is equipped with an oil plate, using the air flow to shock the oil, separating the impurities and sticking it in the oil, and the oil droplets that are surged through the air flow through the filter core and adhere to the filter core. When air flows through the filter core, it can further adsorb impurities, so as to achieve the purpose of filtration.
A filter for purifying air. They have the following differences:
1: machines (such as internal combustion engines and air compressors) intake air to the external intake of air purification;
2: smoke and dust discharge factories and traffic exhaust gases must be purified in advance.
3: the space for purifying the workshop must be up to the high efficiency filtrating device used in the high grade cleanliness level.
There is no consistency between them from material selection to testing and technical indicators, and their standards are different.
