Purpose and working principle:
DAB series moisture-absorbing air filters are mainly used for moisture absorption and filtration of air in fuel tanks. Its working principle is that first, when the air passes through the desiccant, the moisture is absorbed. After passing through the desiccant, when passing through the air filter element, the solid particles in the air are removed, which can effectively prevent the liquid level from rising and falling as well as heat and cold. The pressure difference caused by compression causes water and solid particles to invade the oil tank, effectively improving the performance and reliability of the hydraulic system and extending the service life of the oil and equipment.
