Oil Mist Purifier
Metalworking processes like milling, grinding, turning and drilling generate oil mist that can irritate the eyes, nose and throat. It also can cause damage to sensitive equipment and lead to costly maintenance costs.
Our oil mist filters are designed to capture harmful contaminants at their source before they escape into the air. They utilize Nederman’s unique FibreDrain technology that allows the droplets to coalesce, grow in fibre intersections and drain by gravity out of the filter media.
High-efficiency filtration system
Modern commercial workshops using CNC systems produce fine oil mist that needs to be filtered and removed by an industrial Absolent air scrubber or another top-rated oil mist removal system. This is because the metalworking process involves cooling and lubricating the rotating machinery with fluids that create fine oil mist. This must be removed from the workplace to prevent health risks and maintain workshop efficiency.
Leaving oil in the air can cause a host of health problems, including eye irritation, skin rashes, headaches, high heart rate, shortness of breath and bronchial asthma. It can also contaminate equipment, tools and products by coating them with an oily film. Moreover, handling equipment and product coated with oil can interfere with the production process, resulting in decreased productivity.
The MANN+HUMMEL oil mist air filtration system uses the latest technology to remove fine oil particles from the atmosphere. Its three-stage filtration system progressively cleans the air. The first two stages use coalescing separators to collect oil and droplets of up to 0.4 microns, while the final stage filters the remaining particles. The resulting pure air is then returned to the working area.
The system has a high collection efficiency of up to 95% at 1 to 4 microns. The advanced design of the air filtration system reduces energy consumption and extends filter life. The 18-gauge, seam-sealed cabinet is designed to withstand pressure and eliminate contaminant escape common with stitch-welded or bolt-on panel designs.
Energy-efficient design
An oil mist air purifier is an innovative air filter system that is uniquely designed to eliminate the dangerous and toxic oil smoke in the air that is given off by metalworking fluids used to cool or lubricate parts and tools. The system uses a 3D impact process that collects up to 70% of the oil molecules and recovers them for reuse in a separate process. The remaining filtered pure air is then returned to the working area. oil mist purifier Donaldson Torit mist collectors are available in a variety of configurations, including machine mountable stand-alone units and ducted cellular and central systems. They can be fitted with a choice of filter solutions to accommodate a variety of applications using straight mineral oils, water-soluble coolants and synthetic or semi-synthetic fluids.
Traditional electrostatic and centrifugal separators work relatively well for PM10 and PM2.5 particles, but their pore size quickly becomes clogged by the sub-micron PM1 particles found in the oil mist. A new generation of separators are now available to collect ultra-fine oil mist, maintaining worker health and safety and ensuring compliance with workplace exposure limits.
A special filtration technology in an oil mist eliminator, called packed-bed filtration, allows the smallest PM1 droplets to coalesce on the filter surface and grow in the fiber intersections until they are big enough to drain out of the filter by gravity. This allows the filter to function even when it is saturated, a characteristic that many other filters lose over time.
Reduced maintenance costs
A mist collector can help reduce maintenance costs by preventing oil from accumulating on equipment surfaces, which could lead to corrosion or clogging. Moreover, it can reduce the need for frequent cleanings and repairs, thereby reducing operational downtime and overall maintenance expenses.
An effective mist collector should capture the airborne lubricant at its source, rather than collecting it in an enclosed area. This helps prevent health risks and maintain shop efficiency, while also safeguarding expensive CNC machine parts. Furthermore, it will improve the overall operation of the machine and reduce energy consumption.
Oil mist is generated during metalworking processes when coolant comes into contact with the machine’s components and evaporates into the air. This airborne fluid is known as oil smoke and can be a serious health hazard for machine operators and other workers in the facility. It can also contaminate equipment and create an oily, untidy workspace.
An oil mist collector can protect workers’ health, prevent equipment downtime and ensure compliance with government workplace exposure limits. These systems use a multistage filtration system to remove airborne contaminants from the workplace. The first stage uses a filter to entrain and agglomerate the small droplets of oil into larger particles. The second stage is a cyclonic separation chamber, which filters the particles out of the air. The final stage is a HEPA filter that ensures the removal of any lingering oil droplets.
Reduced health risks
When oil mist is not properly filtered it can cause severe health problems for employees. The particles can penetrate the skin causing contact dermatitis which causes itchy, irritated and inflamed skin which may become cracked and broken. It can also enter the lungs and airways through inhalation. This can lead to shortness of breath, coughing with phlegm, and flu like symptoms, lasting respiratory conditions such as chronic bronchitis and lung damage, and even life-threatening diseases such as hypersensitivity pneumonitis.
The mist can also deposit on surfaces and cause slips and falls which can result in injuries. This can be very dangerous especially for elderly or disabled employees. oil mist purifier It can also contaminate machinery and lead to corrosion and reduced machine performance. Using an oil mist collector protects machines from corrosion and keeps the workplace clean.
Having an oil mist extractor is a legal requirement under COSHH Regulations, but it also makes good business sense to install one. It can help improve productivity, reduce cleaning costs and fire risks, and support employee recruitment and retention. It can also reduce the risk of a lawsuit from employees who have been injured by uncontrolled exposure to metalworking fluids. The UK manufacturing industry has a long way to go in dispelling the image of a dirty, unhealthy workplace, but installing an oil mist filter is a great start.
