The structure of the air filter introduces compressed air from the inlet into the guide plate. The guide plate has evenly distributed diagonal teeth similar to fan blades, forcing high-speed compressed air to produce strong rotation along the tangent direction of the teeth. Liquid water, oil, and larger impurities mixed in the air are separated under strong centrifugal force and thrown onto the inner wall of the water cup, flowing to the bottom of the water cup. Compressed air that removes liquid water, oil, and larger impurities is further filtered through a filter element to remove small solid particles, and then output clean compressed air from the outlet. The umbrella shaped water blocking plate divides the water cup into two parts, with the lower part maintaining a static pressure zone, which can prevent the high-speed rotating airflow from sucking up the water and oil at the bottom of the cup. The water and oil gathered at the bottom of the cup are drained from the drain valve. The air filter must be installed vertically with the water cup facing downwards. The working principle of an air filter is that compressed air enters from the inlet, enters the baffle, and then passes through the baffle. With the cooperation of a fan, centrifugal force is generated, and the water cup is thrown out. Through this repeated action, the discarded air is thrown out, bringing health to people's lives.

In factories, air filters are a necessary filtering device that brings health to the people in the factory by maintaining cleanliness in the workshop, factory building, and laboratory.

The working principle of it is that compressed air enters from the inlet, enters the baffle, and then passes through the baffle. With the cooperation of the fan, centrifugal effect is generated, and the water cup is thrown out. Through this repeated action, the waste air is thrown out, bringing health to people's lives.

If air filters are not installed in factories, the inhalation of waste air by the human body over time can have significant impacts on the lungs and respiratory tract, and even pose a threat to human life safety.

Many times, the function of such devices is not valued, just like people in daily life who know that crossing the street to check their phones is a dangerous thing, but there are still many people who repeat this action until after a traffic accident, only to regret it. At that time, it was already too late to repair everything.

Therefore, this has sounded an alarm for the factory, and the importance of air filters cannot be underestimated.
