China Factory Suppliers for 3 Micron Liquid Filter - Efficient Filtration with 5ppm Oil Residual Content
Filter Core Structure
Class E
Separation Filter
- Suitable for filtering large amounts of liquid and 3 micron sized agglomerates (maximum residual oil content of 5ppm W/W).
- Two non-embroidered holes are separated by a 10-micron machine.
- Filtration of 3-micron solid and liquid particles in a deep fibrous medium.
Class D
Supervisor Filter
- Suitable for filtering large amounts of liquid and 1 micron sized agglomerates (maximum residual oil content of 1.0ppm W/W).
- The fiber medium and the dielectric filter screen are stacked alternately to filter larger particles.
- Multi-layer epoxy resin bonded with mixed fiber medium, coalescing oil mist and filtering solid particles.
Class C
High Efficiency Oil Removal Filter
- Glass fiber multilayer overlap material.
- Air pipe filter: used for general pipelines and general screw air compressors (front-through device).
- Filters compressed air, oil, water, and liquid to 0.01ppm; filters impurity particles down to 0.01 micron.
Class B
Ultra High Efficiency Oil Removal Filter
- Glass fiber medium, including membrane seal network and multi-tube mixed fiber medium.
- Ultra-precision oil filter: designed for air compressors and rear filters.
- Applicable to compressed oil and a small amount of air-filtered water vapor; accuracy is less than 0.001 micron to achieve oil-free standards.
Grade A
Ultra Precision Activated Carbon Filter
- Designed with extremely fine activated carbon powder and multilayer fiber material.
- Acts on high-precision filtration systems.
- Filters residual oil mist in compressed air to less than 0.003ppm, removes carbon ammonia compound odors, and filters ultra-fine particles to within 0.01 micron.
Frequently Asked Questions (FAQ)
What is the difference between Grade E and Grade D filters?
Grade E is a separation filter designed to handle large amounts of liquid and 3-micron particles with a maximum residual oil content of 5ppm. Grade D is a supervisor filter that targets smaller 1-micron particles and reduces residual oil content to 1.0ppm using stacked fiber media and dielectric screens.
Where should a Class C High Efficiency Filter be installed?
Class C filters are air pipe filters typically installed in general pipelines and general screw air compressors as a front-through device to protect downstream equipment by filtering impurities down to 0.01 micron.
How does a Grade A Activated Carbon Filter achieve odor-free air?
Grade A filters utilize extremely fine activated carbon powder combined with multilayer fiber materials. This setup adsorbs carbon ammonia compound odors and reduces residual oil mist to less than 0.003ppm.
What makes Class B filters suitable for ultra-precision applications?
Class B filters use a sophisticated glass fiber medium with a membrane seal network and multi-tube mixed fiber structure. They filter water vapor and oil down to less than 0.001 micron, meeting strict oil-free compressed air standards.
Should these filter cores be used in a specific sequence?
Yes, compressed air filtration systems should follow a progressive sequence from coarse to fine (typically Class E -> D -> C -> B -> A). This prevents high-precision filters (like Class B and A) from clogging prematurely with larger particles.
