Why Invest in an Oil Mist Purifier?
Oil mist is produced during metalworking processes and can create dangerous slip-and-fall hazards. It can also coat equipment and products and reduce productivity.
Our oil mist filters are ideal for workshop environments, including centralized lubrication systems, CNC machine tools and textile manufacturing. The oil drains back into the machine after being filtered through our filter technology.
Cyclone filtration
Cyclonic separation is a method of separating solid particles from an air, gas or liquid stream using rotational effects and gravity. It is particularly effective in removing dust, swarf, and other coarse particulates from the air. In addition to reducing maintenance costs and improving operational efficiency, it also reduces energy consumption by eliminating the need for power-intensive filters. Cyclone separators are available in several different configurations, including reverse flow and uniflow models. The choice of which model to use depends on the type of product handled and specific environmental conditions.
Cyclic separators, which are also commonly referred to as cyclonic dust collectors or cyclonic swarf separators, are the first step in flue gas filtration. They are used in industrial environments to remove large and abrasive particulates from production plant exhaust gases before they can cause damage to other equipment or the atmosphere. They can be made from a variety of materials, including stainless steel. The separated waste from a cyclone separator is collected in an easy-to-empty container beneath the device.
The performance of a cyclone separator is determined by the flow pattern and pressure drop, which can be controlled with fan dampers. The granulometric distribution and the working temperature of the abrasive particle also play an important role. The Tecnosida(r) company has the experience to design cyclones that strike the right balance between energy efficiency and pressure drop, thus ensuring optimal results.
A cyclone separator can be divided into two types based on the way they are built. The reverse flow cyclone is designed with a tangential inlet oil mist purifier at the top of its body, which is shaped to create a confined vortex gas flow. The clean gas exits through a central pipe at the top of the body. In the uniflow cyclone, which is a less common design, the gas enters at one end of the body and leaves at the other.
The main difference between the two types is that the uniflow cyclone has a smaller diameter than the reverse flow cyclone. The lower capacity of the uniflow cyclone allows it to be more efficient, even at low airflow rates. This makes the cyclone ideal for applications with limited space. It can also be equipped with a rotary valve, which eliminates the need for an inlet fan and improves performance.
Circular filtration
If you want to protect your employees from harmful oil mists and smoke in the workplace, you should invest in an oil mist air purifier. These devices are designed to extract harmful contaminants from the air and recycle them for reuse, resulting in cleaner and safer working environments. They also help reduce the amount of oil used in machining operations.
Almost all machine shop processes produce oil fumes or oil mist. They are generated when metalworking fluids come in contact with hot machined surfaces and vaporize into the air. These aerosols can cause a wide variety of health problems, including respiratory irritation and allergic reactions. In some cases, prolonged exposure to these vapors can lead to long-term illnesses like asthma, chronic bronchitis and fibrosis of the lung.
Our Oil Mist Recovery Air Purifier can be integrated into any workshop environment. It features a five-stage filter process that can handle any mist or wet environment. This includes four cleanable mesh pre-filters and an oil bag filter. The collected oil from these filters is drained into the drain plug to be repurposed. The clean air is then returned to the workplace.
The first stage is a stainless steel woven mesh, which immediately separates 90%-95% of the oil particles. This allows the subsequent coalescing separators to target smaller oil particles without prematurely plugging. The second stage is an agglomerator made of oleophilic fibers that attract and concentrate oil. The accumulated oil is then drained into the sump using an adjustable four-way grate.
The final stage of the system is a carbon pre-filter that adsorbs chemicals and eliminates odors. It also helps prevent the loss of oil through the filtration process. The third stage is a main filter, which can be customized to meet the specific needs of your application. This can be an ASHRAE, HEPA or ULPA filter. Our oil mist air purifiers are designed to provide a high level of contaminant removal and long filter life, while minimizing maintenance and operation costs. The ARO series is a perfect choice for industrial machine shops, commercial food production and other industrial environments that generate hazardous metalworking fumes or oil mist.
3D impact filtration
The 3D impact filtration technology offers significant efficiency gains and cost of ownership reductions for a filtration system. These gains are achieved through minimized pressure loss, enhanced purging capabilities, extended filter life and reduced system downtime. It also increases the range of material options and reduces energy consumption.
This professional design utilizes a stainless-steel filter cloth that uses 3D weaving to create irregular collisions between the particles and the oil mist. This collisions cause the mist to adhere to the surface of the filter and accumulate into droplets that are easily removed from the filter. The resulting filter is also less likely to clog, and can be cleaned easily using standard industrial sanitizers.
As the airflow through a filter is directly related to the number of pores in its surface, increasing this area increases flow capacity. A woven metal filter such as the MINIMESH RPD HIFLO-S provides more holes than a 2D weave, doubling its surface area and allowing twice as much fluid to pass through it. This allows for higher rates of flow, which is important in many applications.
The soiled paper filter in an oil mist eliminator is not very effective at catching the low molecular weight hydrocarbons and volatile aromatics that can contaminate vacuum pump oils. It is only effective at capturing the heavy components from the oil. To capture these oil mist purifier lighter components, a carbon trap is used instead of the paper filter in an oil mist eliminator.
The Alcatel and Edwards oil mist eliminators mount on the vacuum pump exhaust port through a standard NW (or QF) style fitting. As the vapor exhaust from the vacuum pump passes through the oil mist eliminator’s paper element, it escapes through its top port. This exhaust air is analyzed after passing through the oil mist eliminator and before entering laboratory air. The results shown in the chromatograms below demonstrate that both the vacuum pump exhaust (top chromatogram) and the exhaust after the oil mist eliminator exhibit high concentrations of volatile aromatics and hydrocarbons. The vacuum pump exhaust is not exhausted into laboratory air, however, because the heavy hydrocarbons are trapped by the oil mist eliminator.
HEPA filtration
The last stage of filtration in an oil mist purifier is the HEPA filter. This filter is designed to capture the smallest particles that could harm human health. The HEPA filter uses a combination of several techniques to trap air-borne contaminants. These include cyclonic, tangential, and centrifugal. The HEPA filter also consists of tightly packed fibers that create a strong pressure drop. Because the fibers are so tightly packed, they can catch a large number of microscopic particles. However, the high pressure drop that HEPA filters cause can cause problems with air flow. This can lead to a decrease in air flow, which is detrimental to the health and safety of workers.
In addition to removing oil mist, industrial mist collectors can also remove dust, smoke and fumes from metalworking applications. These systems are designed to eliminate harmful contaminates in the air while reducing operating costs and maintenance requirements. They can be used in many different industries, including metalworking and commercial food production.
Most filtration systems are rated by how much clean air they can produce, and they typically promote a clean air delivery rate (CADR). However, most don’t look at the quality of the air they are cleaning. A true HEPA air purifier can trap particulates that are 0.3 microns in size. This can help reduce the risk of asthma attacks and allergies.
A typical industrial mist purifier will start with a pre-filter that captures the larger particles in the air. This can be a stainless steel woven mesh or a sleeve. It can also be a coarse screen or an electrostatic precipitator. The second filter is a stainless steel coalescing separator. This removes 85% of the oil mist in the air and diverts it to a drain. The third filter is a HEPA separator that removes the remaining 15% of the oil mist in the air. The HEPA filter will then return the cleaned air back into the workspace.
ARO Premium Mist Collectors are a great solution for any industry where there is a need to protect workers from the dangers of oil mist and smoke. Their innovative multi-stage filtration process offers exceptional long filter life and contaminant-free air, while minimizing operation and maintenance costs.
