What is Oil Mist Collector (Oil Mist Air Cleaner)?
Oil mist collector (oil mist air cleaner) is an innovative air filter system uniquely designed to remove oil mist or oil smoke in the air that is given off when metalworking fluids are used to cool or lubricate parts and tools during the metalworking process and collect the recovered oil for reuse. Juwei is an oil mist collector manufacturer from Taiwan, we provided a mist recovery air purifier (oil mist air cleaner) that incorporates a 3D impact process that collects up to 70% of oil mist molecules from the incoming air for reuse. Further filtration then returns pure air back into the working area.
The oil mist collector unit is designed to conveniently mount to existing machinery so minimizes installation costs. This highly stable filtration system is designed for maximum efficiency with low vibration and noise so it will not interfere with the operation of the machine it is attached to. The unique, high-speed impeller process provides a high suction, the centrifugal cyclone that achieves the best oil rejection. Further filtration steps then purify the air. Juwei oil mist collector (air cleaner) advanced air purification technology provides filtration efficiency as high as 99.95%~99.995%.
Juwei purifier (oil mist air cleaner) is equipped with a filter life indicator that clearly shows the correct time for filter replacement. On-time filter replacement will reduce power consumption and ensure efficient oil and dust removal for high-quality air purification. Juwei can provide customized color designs to create an Oil Mist Recovery Collection System with an attractive appearance that will enhance your company’s overall image.
How Does Oil Mist Collector Work?
Iron Chips and Particle Screening
The first layer of filtration is a stainless-steel woven mesh located in the interface between the machine equipment and the oil mist recovery collection system. This filter layer can prevent iron chips from entering the air purifier, preventing iron chips or other impurities from disrupting or damaging the oil mist recovery collection machine. 70% of the remaining oil mist will pass through to the next layer where it will be collected by the 3D impact separation process. The stainless-steel mesh can be disassembled, cleaned, and reused, making for convenient maintenance and considerable cost savings of consumables.
Incoming air is drawn into the purifier by a specially designed centrifugal fan impeller which creates a unique cyclone effect that increases the efficiency of oil collection. As the air passes through the next filter stage, this cyclone effect will generate static electricity which will enhance the adsorption of oil mist onto the stainless-steel woven mesh.
Oil Separation and Collection
The third stage is a large screen with an expanded surface area to increase the efficiency of oil recovery. The filter screen is specially designed to incorporate a cyclone flow pattern for excellent filtering efficiency.
The fourth stage incorporates a high-speed centrifugal impeller to create a high suction cyclone that forces oil mist to adhere to the inner wall of the filter. The intercepted oil mist is collected by the internal oil baffles.
The final stage of filtration is a barrel-type HEPA filter. After most of the oil and larger particles have been removed by the first four stages, the HEPA filter will capture any remaining sub-micron mist and smoke particles and return highly purified air back into the working environment.
300mm and 600mm Cartridge Filters
Juwei provides HEPA cartridge filters in two sizes; a 300mm barrel filter and a 600mm cartridge filter which can be purchased according to your needs. For light machining processes that only give off coolant mist, oil mist and water vapor, you can choose a 300mm barrel filter. For machining processes that involve heavy-duty cutting, where high temperatures may produce oil smoke or fumes, a 600mm barrel filter will be required to properly remove oil smoke particles.
The 600mm HEPA cartridge filter can also be used for applications where only water vapor and oil mist are given off, allowing for longer operating times between filter changes. If you are unclear about which barrel filter will be best suitable for your machining processes, please contact us and we will be glad to help you make the right choice.
Juwei is a professional manufacturer of oil mist recovery and air purification filter systems. With years of accumulated experience in the industry, we continue to develop and improve the efficiency of oil mist recovery filtration systems. Juwei has experience with many types of air filtration systems which have been applied to a broad range of working environments.
Juwei oil mist recovery and air purification systems are widely used in the mechanical processing and machine tool industry, semiconductor and electronics industries, petrochemical industry, catering industry and more. These quiet running, low volume, compact, energy-saving air purifiers can be easily installed directly onto existing machines. An oil mist collector can improve air quality and work efficiency in nearly any location where oil mist is present. The filter system is easy to disassemble for servicing and cleaning, reducing the cost of maintenance and consumables.
3D Impact Principle
The 3D impact principle is a unique professional design of Juwei. The principle uses a thick filter of various grades of woven, stainless-steel fibers. These fibers create irregular collisions that help oil mist adhere to the filter. Oil droplets gradually accumulate and are returned to the machine. This stainless-steel filter mesh can be easily cleaned to extend the service life of the filtration system.
Pleated Filter Material
Juwei uses circular pleated filter material to increase the filtration area and improve the filtration efficiency.
HEPA Air Purifying Filter
Machining processes can often generate very fine particles or smoke which can only be removed by a highly efficient HEPA filter. To assure the air returned back to the working environment is of excellent quality, the final stage of the Juwei Oil Mist Recovery Air Purifier is a barrel-type HEPA filter. The HEPA barrel filter conforms to the European H13 standard. With an efficiency rating of 99,97% for 0.3 µm particles, this final HEPA filter returns highly pure air back into the working area.
Depending on the working environment, HEPA filters of varying efficiencies are available to choose from. The HEPA filter barrel is designed to screen out particles larger than 0.3 µm, with an efficiency of 99.99%.
The Juwei Oil Mist Air Purifier uses HEPA EU-H13 grade filter material, which conforms to the European EN1882 specifications. It has a filtration efficiency of 99.95%~99.9995% or more for MPPS. (Most Penetrating Particle Size) An optional activated carbon filter is available to absorb odors and further enhance air purification.
Oil Mist Collector Filtering Efficiency
Oil mist recovery of up to 70%
The first stage of the system is a woven stainless steel mesh. In addition to effectively preventing iron chips from entering the air duct hose. In addition, some of the oil recovered at this stage is allowed to flow directly back to the machining work area. Removing a large percentage of debris and oil in the first stage will increase the efficiency, speed, and service life of the following stages.
Oil Mist Collector Recovery Efficiency
Up to 70% of oil mist and processing fluid will be recovered by the filter system. Up to 95% of this recovered oil and fluid can be reused in the machining processes. In actual on-site testing, the filter system has been able to filter out more than 99.5% of oil mist.
Even during times when the factory’s machine tools are not in operation, running the Juwei Oil Mist Recovery Air Purifier will improve the quality of ambient air in the factory.
