About Oil Mist Air Cleaner

In the cutting industry, lubricant, coolant, and many other cutting liquids are necessary components for machine tool users to prepare when they are conducting a machining task, as we know that cutting metal would naturally leads to many frictions, chips, and heat issues.

Therefore, those liquids and metal particles always spread over into the air in the working area, causing great contamination to workers in the manufacturing plant and that is a serious occupational safety hazard. Therefore, how to deal with those liquid and metal chips as well as all those particles becomes a serious topic since the 1980s in the US market.

Other contaminations

Besides, there are also many other contaminations in the machine tool factory that cause health issues more than the spreading liquid and metal chips do, such as gas, oils, waste air emissions by the engines and starters, and so on and so forth. Those emissions together would cause severe chronicle occupational injuries to onsite operators that will last permanent.

Oil collector

Began in the late 1990s, the oil-mist collectors are under development thanks to the invention of new motor powers. With better inlet force, oil mists are now efficiently inhaled into the filter which is driven by the new motor power source.

With this invention, the contaminated air is drawn into the inlet below the first stage filter where the majority of the oil particles are trapped. When the stage one filter reaches a state of saturation, the oil droplets will coalesce and drain down into the sump located below the filter collected oil.

This procedure is automatically pumped away for re-use air passes through a second stage filter, where finer mist and smoke particles are filtered out and coalesced third stage is a non-wicking final filter, which captures the remaining smallest particulate down to 0.30 microns. The clean air is then discharged from the top of the collector into the facility.

Air filtration

Most industrial air filtration systems and industrial oil mist collector solutions can help protect factory employees and equipment investment, and can clean up the shop area and take stress off of users’ overall system. Image, if all those metal and oil particles are attached onto the manufacturing facility, with time passes, people using them and those equipment are all severely contaminated and rust will happen, leading to mal-function in many aspects.

Industry-oriented

Since in the manufacturing or metalworking industry, the existence of oil mist is so unavoidable, because when fluids used to cool or lubricate metal working tasks, it disperses oil mist, and even possibly smokes, into the air immediately after coming into contact with any fast-rotating tools.

All the mist and smoke have varying types of risk factors, but exposure should be reduced as much as possible. As a result, the oil mist collectors normally use a loft fiberglass filtration medium to collect H2O or petroleum-based machining coolants.

With this idea, the industrial air filtration unit’s vertical design with three stage filtration helps drain off excess coolant, and keeps the filters cleaner longer and effectively filters out the hazardous smaller size mist created by high-pressure high flow machining centers nowadays. In addition, the industrial oil-mist air filtration systems can give customers with the option of cleaning all the ambient air in the plant.

Deep insight: what is oil and mist?

In the today’s industry, manufacturing or any type of metalworking, fluids are used to cool and lubricate any machining activity: that is, to reduce friction and eliminate wear on machinery. These fluids contain different oils or minerals and contaminants in them to protect the metal and ensure no reaction from the machining activities on the machines.

When, say, these fluids come into contact with fast-moving tools, they cause oil mist, which is dispersed into the air. They can also cause smokes, as both due to the high temperatures of the metal parts during machining. Accordingly, there are regulations on the limit of exposure to oil mist nowadays, but there are many different makeup of these fluids, making it difficult to define how much exposure is too much.

For that reason, and for the purpose of keeping the manufacturing site clean from smokes and mist that may damage or increase wear out rates on other machinery, industrial air filtration or ventilation system is a smart investment to make to avoid big maintenance costs.
