Oil Mist Purifier

Oil mist purifiers are used for the extraction and filtration of air contaminated with oil. They work by a physical process called coalescence.

Exposure to oil mist can cause a variety of health issues including eye irritation, skin rashes, headaches, shortness of breath, vomiting, and fever. It can also lead to breathing problems and bronchial asthma.

Air flow

A good quality oil mist air cleaner needs to have a sufficient air flow through it to effectively collect the fine droplets of coolant or other liquids that CNC or other industrial machine tools produce. These machines require special coolants or lubricants to run correctly and will release the resulting fine airborne metal particles into the work area, requiring an oil mist purifier that can filter these contaminants out of the air and keep them away from workers.

The A*mist oil mist recovery system begins with an innovative first stage separator that separates and drains up to 90% of the mist and swarf, while simultaneously cleaning the contaminated air using a washable filter. The contaminant-free air then passes through a second stage of separation and filtration, with an energy saving EC fan that provides the necessary airflow to effectively remove the fine mist particles.

The air is then filtered through a barrel-type HEPA filter, which captures the remaining oil and other particles, leaving only clean, breathable air behind. The HEPA filter is tested and certified to meet the MERV 15* standard, meaning that it filters at least 95% of small particulates down to 0.3 microns or less. The resulting clean air is then returned to the workshop, providing safer and healthier working conditions. The filter also helps to lower maintenance costs, improve environmental compliance and reduce energy usage.

Filtration

The oil mist is collected by a special filter called a packed-bed or coalescing filter. This type of filter works differently from other filters in that it continues to work even after the filter becomes saturated with oil. This feature allows the filter to drain the oil and prevents it from being released into the atmosphere, where it could act as a pollutant. This technology also prevents the loss of valuable lubrication oil, which results in more efficient operations and reduced operating costs.

When contaminated air passes through the filter, it is scrubbed by the oil mist purifier oleophobic fibers that collect the oil droplets. These droplets cling to the oleophobic surface and are trapped in the coalescing chamber until they are larger enough to become heavy and fall to the bottom of the filter. The collected oil is then drained and sent back to the machine tool sump or lubrication system for reuse. This process separates the mist from the vapor and dust that is normally emitted as oil smoke and a potential fire hazard.

The mist collector and filtration system helps to maintain clean air in the shop, which will help your employees stay safe and productive. The system can also save you money by allowing you to reuse lubricant oil and processing fluid from your CNC and other industrial machines. It can also reduce your housekeeping costs and increase equipment efficiency. When selecting a lubricant for the system, it is important to choose a quality mineral oil that is free of paraffin. Paraffin can plug the reclassifiers in the system, resulting in alarms sounding.

Noise level

Depending on the type of mist collector, noise levels oil mist purifier vary. Look for models with low decibel ratings (dB) so that you can work in comfort. This can improve the working environment for machine operators and help reduce health risks.

When it comes to choosing an oil mist collector, you need to consider the air flow rate and filter options that best suit your needs. Some oil mist purifiers can be fitted directly to a machine, while others need to be connected to a ducting system. If you’re unsure of which model is best for your needs, ask the manufacturer or an expert to help you choose the right product.

The multi-stage design of LNS oil mist purifiers eliminates the maintenance requirements and energy consumption of electrostatic systems and the noise and vibration problems of centrifugal units. They also provide verifiable, continuous filtration efficiency.

The first stage of the multi-stage filtration system consists of a coarse pre-filter that separates large particles and absorbs excess oil. The second stage is a coalescing separator that collects fine droplets and agglomerates them into larger particles. The third stage is a high-efficiency filter that delivers up to 99 percent filtration efficiency. This filter is also washable, which helps keep it in peak operating condition. The resulting filtered air can be recirculated to the workplace without loss of energy.

Maintenance

The lubricant used in machine tools creates smoke and mist that may be hazardous to employees’ health. It can also contaminate the facility’s air. To prevent these hazards, an oil mist collector can be installed on a rotary pump. This device exhausts the oil mist into a separate system and returns clean air to the facility.

An oil mist purifier requires regular maintenance to function properly. Performing this maintenance can help reduce downtime and ensure compliance with air quality regulations. However, you must be sure to select the right type of mist collector to keep your equipment running smoothly. The best option is a cartridge oil mist collector, which offers less downtime and maintenance than cyclonic systems.

A good mist collector should have a packed-bed filter that’s designed to collect and drain oil from the air. Its media is bonded with resin-free binding fibers to enhance wet collection, and it’s sized for each coolant type. It also should have a dedicated stage to handle smoke. It is important to avoid using a filter that can clog easily, since this can cause low airflow and loss of lubrication.

To minimize downtime, you should choose a system with a differential pressure gauge that tells you when the primary filter needs to be changed. Then, you can replace the dirty cartridge and install a new one without having to take the whole system apart.
