dt series compressed air filter
about compressed air filter
◆ coalescing filter
the coalescing filter is perhaps the most important item in the purification equipment. they are not only designed to filter oil mist and water, but also to filter solid particles to an acceptable level, such as 0.01 μm. in the installation system, the first filter acts as a pre filter to protect high-efficiency filtration from large area pollution, thus providing high-quality compressed air. if the air filter works in the wet or full water state, it will make the compressed air unable to pass through the filter element, and the air flow will force the liquid to pass through the pores of the filter medium, increase the working pressure drop of the filter and reduce the performance of the filter.
◆ activated carbon filter
oil vapor is oil passing through coalescing filter as easily as compressed air in the form of a gas, so adsorption filter needs to provide a large activated carbon adsorption bed to keep efficient oil mist filtration and remove peculiar smell. as the wet air will reduce the adsorption of activated carbon, it is generally installed at the back of the adsorption dryer. activated carbon filter is not used to remove liquid oil or sol. poor maintenance or no pre-filter will accelerate its performance failure.
◆ dust filter
the dust filter is generally installed at the back end of the adsorption dryer, which brings dust particles.
recommended for wire cutting, automation, cosmetics, blow molding, spraying and other industries.
the following flow is the compressed air treatment flow under the working pressure of 7bar (100 psig). for other applications under the working pressure, please refer to the following pressure correction.
