MANN+HUMMEL OIL MIST PURIFIER

MANN+HUMMEL’s mist collector technology separates oil mists, oil smoke, and oily dust from air. It ensures safe workshop environments and keeps machines working efficiently.

Mist and smoke are produced when machining operations such as turning, milling and grinding occur. They can create health hazards for workers and contaminate expensive CNC machine parts. Source capture reduces maintenance, downtime and energy costs while complying with workplace exposure limits.

Filtration Stages

Long-term exposure to oil mist is a health risk and it can contaminate the working environment as well as products, machines and equipment. It also lowers productivity and affects the quality of the end product. The best way to avoid this is to have an oil mist removal air system in your workshop.

These systems extract the oil mist at the source and remove it from the surrounding atmosphere. They consist of multiple filter stages which are designed specifically for the elimination of oil vapors and mist.

The 1st stage mechanical element separates the oil mist and swarf from the coolant. The swarf is then drained back into the machine sump.

Air passes through a layer of stainless steel mesh that is weaved with oil attracting oleophobic fibers. This creates irregular collisions which causes the oleophobic particles to adhere to the fibres and collect until they are large enough to fall down from the filter. This process is known as coalescing. The air is then scrubbed in stage two, where a deeper fiber bed is used to capture smaller particles. This filter has a high MERV (Minimum Efficiency Reporting Value) 15* filter rating.

The filtered air is then directed through an adsorptive carbon cartridge to remove any residual odours and vapors. The OIL MIST PURIFIER filtration system is compact and consists of up to 4 filtration stages.

Cyclone Effect

Cyclones are ocean storms that spin around a low-pressure area in the center. They cause immense wind and rain that lead to flooding, loss of life and destruction of property.

Oil mist adversely affects health of machine tool workers and is a major contributor to workplace accidents. It is therefore essential to prevent the spread of these contaminants. This is why regulations on the limitation of the exposure of oil mist are getting stricter.

The Apiste GME Series utilizes a cyclone design with multiple disks to effectively collect and remove oil mist particles from the airflow. The collection efficiency depends on the geometry of the cyclone and the rotation speed of the motor.

A branded filter has better quality factors (ratio of capture efficiency to pressure drop) than a clone separator or catch can, thanks to its more effective separation media and larger and finer separation particles. This filtration method enables the removal of more than 99.9% of oil mist at a particle size of less than 0.3 mm, making it suitable for CNC lathes, CNC integrated cutting machines, hobbing machines, grinding machines, washing tanks, closed working areas and so on.

Stainless-Steel Woven Mesh

Stainless-steel woven mesh is ideal for filtering applications due to its strength, durability and corrosion resistance. Its high tensile strength is also ideal for resisting impact and break-in attempts. Woven wire mesh has numerous openings that allow light, air and sound to pass through unobstructed. This allows for better visibility and circulation and superior acoustics within a facility. Woven mesh can also block passersby from seeing into your facilities, providing a sense of privacy and security on top of its protective capabilities.

During machining, milling and grinding processes, metalworking fluids are aerosolized into oil mists. This mist clogs machines, causing expensive downtime and reducing productivity. Oil mists can also contaminate delicate electronics. Oil mist collectors are effective at removing this airborne contamination from your facility, improving overall shop health and lowering maintenance costs.

The mist recovery air cleaner from Juwei consists of a thick filter made from different grades of woven stainless-steel wire. This filter collects the oil molecules through a 3D impact process and filters them away before returning pure air to the workplace. The result is significantly less oil mist on the machine and its surrounding surfaces, as well as lower maintenance and energy costs. Additionally, the less oil mist in the shop, the less it can corrode your machinery, leading to higher productivity and efficiency.

HEPA Filter

The HEPA filter is a special type of air filter that can trap fine particles and prohibit them from re-entering the air. It’s so effective at capturing particles that it meets stringent government standards for use in cleanrooms and other environments where the presence of hazardous substances like radioactive dust must be kept under control.

The filter works through a combination of mechanisms to trap particles. The smallest particles (down to 0.3 microns in size) are captured through a process called diffusion. The OIL MIST PURIFIER physics behind this mechanism is that the smaller the particle gets, the more it can bounce around and collide with gas molecules in the air stream. Over time, this raises the probability that the particle will come within one diameter of a fiber in the filter and stick to it. The medium size particles are collected through interception or impaction.

Both of these mechanisms are very efficient at capturing the majority of the harmful airborne pollutants that pass through the filter. This includes pollen, mold spores, dust mites, pet dander and other allergens as well as bacteria.

However, there are other harmful contaminants that a HEPA filter doesn’t address. These are chemicals known as Volatile Organic Compounds (VOCs). VOCs are off-gasses from many building materials, cleaning products and other common household items. They can be very damaging to health since they can react with other pollutants and penetrate deep into the lungs to enter the bloodstream.

Oil Mist Purifier – Keep Your Workers Healthy, Safe and Productive

Industrial oil mist filtration removes airborne oil from commercial workshops with CNC and other machine tools. This helps to keep your workers healthy, safe and productive.

Oil mist eliminators use coalescing filters to separate out oil from contaminated air before it is expelled from the shop. This prevents clogged heating and cooling systems and reduces maintenance costs.

Reduces Health Hazards

When metalworking fluids like coolants and lubricants become airborne, they OIL MIST PURIFIER can have serious health impacts on workers. Mists and fumes that contain chemicals irritate lungs, skin, eyes, and nose, and can lead to long-term problems with breathing, including respiratory disease and lung damage. They also cause slip-and-fall hazards on floors and surfaces and can make them slippery, resulting in workplace accidents that decrease productivity and raise maintenance costs.

The health effects of oil mist vary, depending on the type of metalworking fluid used and the chemicals in it. However, all oil mist can cause respiratory irritation if inhaled for long periods of time, and prolonged exposure has been linked to asthma, chronic bronchitis, impaired lung function and pulmonary fibrosis. In addition, some metalworking fluids can cause skin irritation and contact dermatitis if it becomes absorbed through the skin.

Additionally, if oil mist accumulates on machines or the surrounding environment, it can create a fire hazard. Moreover, it can lead to corrosion and the failure of sensitive electrical equipment. Using an industrial air cleaner to eliminate oil mists and fumes from the work environment protects human health, prevents expensive machinery repair and replacement, and reduces downtime and waste. It also safeguards your business from costly worker liability and healthcare costs associated with workplace contamination.

Reduces Maintenance

Oil mist can damage machinery, resulting in costly repair bills and lost production time. A top-rated industrial Absolent air filtration system can prevent damage and increase productivity by cleaning the air around machine tools and in workspaces. This protects workers and equipment, reduces maintenance costs, and allows your company to comply with workplace exposure limits.

Anytime metal-working machines are used in manufacturing, such as CNC machining, grinding and polishing, or welding, they produce fine oil mist. The mist is produced from cooling and lubricating fluids used to keep rotating machinery in good working condition. Without an oil mist extraction system in place, the fine particles of dissolved oils will build up on machinery and equipment over time, causing corrosion and clogging of airways. The resulting sticky film will attract dust and dirt, leading to expensive maintenance and increased downtime.

Our oil mist extractors remove the fine coolant mist and vapor at the source of production, returning clean air to the shop. They have multiple filter stages that separate the mist from the air, removing both oil and solid particulates. The first filter stage consists of stainless-steel woven mesh that protects the oil mist recovery system from iron chips and other impurities. This layer prevents rust, corrosion and premature wear of the system and ensures optimal performance. The second stage combines three filters that remove solid particulates, entrain bulk liquids, and agglomerate fine mist droplets into larger particles for capture and removal. The third stage is a centrifugal separator, which uses the force of centrifugal acceleration to separate the mist from an airstream and carries it to a drain point for collection.

Reduces Waste

Oil mist is an inevitable by-product of metalworking and many other processes that require lubricants, coolants or other fluids. It can be caused by leaks, overheating of lubricants and equipment malfunctions. If left uncontrolled it can disperse into the production environment, harming people, machines and products.

It poses health risks when inhaled, and prolonged exposure has been linked to respiratory problems such as asthma, bronchitis and impaired lung function. It can also cause skin irritation and dermatitis. When dropped, it can coat machinery and products making them unusable or stain them. It can also create a slippery surface that results in accidents and injuries, especially when it hangs in the air and drops onto workers.

A good air filtration system for metalworking fluids removes the harmful particulates and returns clean coolant to the machine tool. This reduces the quantity of industrial environmental special waste and allows you to extend your coolant life. An efficient depuration system also improves productivity by reducing machine stops for maintenance.

An effective oil mist filtration system captures the oily droplets using coalescing filters that are specially designed to collect oil mists. Filter media that is progressively structured from tightly woven fibers works best for mechanically and thermally generated oil mist. It can even handle some dry-soluble particulates that simply wash away with the liquid as they coalesce.

Reduces Energy

When mist collects on machinery or surfaces, it can leave behind a layer of oil that stains floors and surfaces and hangs in the air, creating a safety hazard. It can also irritate lungs, skin and eyes. An IVEC air cleaner captures oil mist before it can escape from the work area and keeps it out of the air for a healthier, safer working environment.

The first step in an IVEC oil mist collection system is a pre-filter that strains out large solid particulates, ensuring the mist makes it all the way to the packed-bed filter. Packed-bed filters made with multiple layers of tightly woven fibers can be used for mechanically and thermally generated mists. They can also handle dry-soluble particulates, which simply wash away with the liquid as the coalescing process occurs.

Packed-bed filter technology also can reduce energy use by preventing the mist OIL MIST PURIFIER from escaping from the work area. This can reduce the load on a machine’s HVAC system and increase the amount of time between planned maintenance visits.

Commercial-grade oil mist recovery and air filtration systems can be easily installed directly on the CNC or other machines in your industrial shop. They can save energy and money by reducing the load on a machine’s HVAC, as well as cut down on housekeeping costs for cleaning up dust and grease.
