The compressed air precision filter mainly filters the solid particles in the compressed air, and has a certain blocking effect on the liquid water and oil. Generally, three precision filters are installed at the front end of the dryer, mainly used to remove oil and impurity particles in the compressed air, and one high-efficiency precision filter is installed at the back of the dryer, mainly used to remove fine dust in the compressed air.
The air permeability of the precision filter element: The filter element adopts the strong hydrophobic and oleophobic fiber filter material from the United States. At the same time, it adopts a framework with good permeability and high strength to reduce the resistance caused by passing.
High efficiency of precision filter element: The filter element adopts German fine-opening sponge, which can effectively prevent the oil and water from being entrained by the high-speed airflow, so that the small oil droplets passing down gather at the lower end of the filter element sponge and discharge to the bottom of the filter container.
Air tightness of the filter element of the precision filter: A reliable sealing ring is used at the junction of the filter element and the filter housing to ensure that the air flow is not short-circuited and prevent impurities from directly entering the downstream without passing through the filter element.
Corrosion resistance of precision filter element: The filter element adopts anti-corrosion reinforced nylon end cap and anti-corrosion filter element frame, which can be used in harsh working conditions.
Filter element testing standard:
(1) ISO 2941 filter element-test method for filter element rupture resistance
(2) ISO 2942 filter element-hydraulic filter element structural integrity test method
(3) ISO 2943 Filter Element-Test Method for Compatibility of Hydraulic Filter Element Material and Liquid
(4) ISO 3723 filter element-end-to-end compliance test
(5) ISO 3724 filter element-determination of fatigue characteristics
(6) ISO 3968 filter element-differential pressure flow characteristics
(7) ISO 4572 filter element-multiple pass method to determine filter characteristics
Effect if you choose inferior precision filter
1. Blocking the pipeline, causing malfunction of valve equipment;
2. Wear pneumatic equipment and shorten the service life of the equipment;
3. Contaminated products and the rate of defective products will increase;
4. Affect the normal operation of the dryer equipment and shorten the service life of the adsorbent.
If the compressed air quality is poor, the reliability of the entire compressed air system and the service life of the equipment will be greatly reduced, which will cause immeasurable losses. Therefore, the compressed air precision filter must be installed correctly.
