Capture and Control of CNC Oil Mist: Success of FumeKiller® model FK2000DPEM

Introduction:

The FumeKiller® finds use across a variety of applications. One of these is as an oil mist collector and on multiple occasions, the FumeKiller® has proven its mettle as an effective and efficient filtration system. In this post, we dive into one such project where the FumeKiller® was successfully implemented as an oil mist collector.

The Challenge: Control of Oil Mist Generated from CNC Machining Process.

The customer, a well known and established player in the manufacturing industry was facing a common issue faced when using CNC machines – Oil Mist.

The customer’s process involved use of neat cutting oil and the mist generated from the machining process would escape into the shopfloor when the doors to the CNC machine was opened after completion of the process. This led to the following issues:

  • Reduction in air quality within the shopfloor along with a possibility of oil mist settling within gaps of other machines and potentially cause critical systems failures.
  • Released oil mist also meant loss of usable neat cutting oil which would accumulate over time.

Any solution provided to the customer would need to be designed with all the above problems in mind and effectively solve each issue.

The Solution: Single FumeKiller® model FK2000EPEM mounted close to the CNC machine.

While the primary problem of air pollution was straightforward, the secondary issues needed to be addressed as well. After a thorough study of the workspace, the solution we proposed was to mount a FumeKiller® model FK2000DPEM near the CNC machine. The unit would be mounted on a groutable pipe stand at height greater than the CNC machine itself and the extracted oil mist could be reclaimed from the FumeKiller® drain point. The advantages of this proposed solution were as follows:

  • Mist Evacuation Methodology: The solution made use of the concept of evacuating the entire volume of air within the CNC machine within a certain time frame, usually 5 seconds, before the doors were opened after completion of the process. This way, the generated oil mist, which would also be evacuated out of the machine would not get released into the shopfloor.
  • Dual Pass Filtration: For applications involving oil mist, the filtration system needs to be equipped with two separate filters positioned one after the other to ensure a higher efficiency of filtration. Using the dual-pass system, the filtration efficiency would go up from 95 – 97% to 98 – 99%, which would imply that the air released into the shopfloor after filtration would be even more clean.
  • Collection of Filtered Oil: The FumeKiller® unit used electrostatic filter modules from which the oil particles would flow down as they accumulate. The filtered oil can then be reclaimed from the drain point provided on the unit itself and reused later.

Results and Impact:

The implementation of the FumeKiller® was a success which allowed for multiple benefits to our client:

Improvement in Air Quality: The complete volume of air within the CNC machines, which would include the generated oil mist, was being evacuated before the doors were opened and therefore, with no release of oil mist into the shopfloor, it resulted in a significant improvement in the air quality.

Operational Efficiency: The FumeKiller® model FK2000DPEM is a single oil mist collector unit that was equipped with a dual-pass filtration system, allowing for greater efficiency of filtration and therefore, even cleaner air being released into the shopfloor.

Cost Savings: Because the filtered oil could be collected and reused, the neat cutting oil for the process was more efficiently and economically used, which resulted in a direct reduction in operational costs.

Regulatory Compliance: The successful implementation of the FumeKiller® as an oil mist collector resulted in the customer meeting the required air quality standards within the shopfloor.

Conclusion:

This project is another example of the capability of the FumeKiller® and its effectiveness as an oil mist collector. With the variety of applications that the FumeKiller® is able to be implemented in, it is safe to say that it is probably one of the most effective air pollution control system available today.

Application of FumeKiller® as an Oil Mist Collector

At site, 8no.s of CNC machines in a row had to be provided with suitable mist collectors. All CNC machines generated mist / fumes from neat cutting oil which had to be captured and the pollutants in the fumes are to be filtered effectively. 

Our FumeKiller®, electrostatic filters are well-suited to capture and control fumes generated during machining processes in CNC machines. These fume extractors can be used for the control of oil mist (neat cutting oil) as well as coolant mist (water-based coolant). Lower suction capacity fume extractors (FumeKiller®) can be installed for individual CNC machines. In case of multiple CNC machines larger capacity fume extractors can be installed along with suitable ducting to capture and route the generated fumes from the CNC machines to the oil mist collector (FumeKiller®). For neat cutting oil fumes, we always recommend Dual-pass electrostatic filters to provide high-efficiency filtration of fumes / mist. For water-based coolant fumes / mist single -pass filtration extractors work satisfactorily.

The installation was carried out using our FumeKiller® model FK6000/5hp mounted on a low MS angle stand with a large oil collector tank below the stand. MS ducting was mounted above the row of CNC machines with droppers to connect individual CNC machines. Last- mile connections were provided using PVC flexible hose. Even though our standard FumeKiller® model FK6000/5hp uses a 3HP motor to drive the suction fan, in this case we used a 5HP driven suction fan to provide higher static pressure because of the length of ducting involved.  

It was found that for a 2-shift operation, the filters within the oil mist collector filtered the pollutants for 4 weeks before getting choked. The cleaning cycle for the filters was established at 4 weeks. Just before getting fully choked, the filter module as well as the prefilters and postfilters are removed and cleaned using pressure water pump at about 110bar pressure. The filters are dried using a compressed air jet and repositioned inside the fume extractor. Adequate training was given to the maintenance technicians to handle the equipment. All safety features were explained and demonstrated. The equipment was found to be working satisfactorily.

Control of Component Welding Fumes – Fumekiller® model FK3600EM as a Welding Fume Extractor

The special purpose machine has two adjacent component welding stations. The welding fume generation area is open, without any enclosure. The welding process takes place only at one station at a time. The jobs are loaded manually by a skilled operator. During welding fumes are generated which are to be captured and the pollutants in the fumes are to be filtered effectively.  

Our Fumekiller®, electrostatic filter model FK3600/3hp was suggested to be mounted on an MS Grouted pipe stand of about 5ft height positioned just behind the welding machine. Two MS painted suction hoods were placed just above the two welding stations at a convenient height after studying operational comfort as well as optimum fume suction distance. The suction hoods were connected to a common MS ducting fitted to the Fumekiller® equipment and supported from the fume extractor.

The fume extractor was switched on during the welding process. The welding fumes generated at the two component welding stations were captured by the fume extractor through the 2nos of suction hoods placed above the welding spots effectively. The fume extractor should be operational as long as the welding process is being carried out.

The welding fumes consisting of various pollutants such as manganese, chromium, nickel, and other potentially harmful elements, enter the electrostatic filter (Fumekiller®) through the air stream. The ionisation section of the filter charges all particles 0.01 micron and larger in the air stream. The air enters the collection section where the pollutants adhere to the collection plates. Pollutants as small as 0.01 micron and larger are collected. The clean air is let out at the exhaust port of the fume extractor.

It was found that for a single shift, the filters collected the pollutants for about 3 weeks before getting choked. The cleaning cycle for the filters was established at 3 weeks. Just before getting fully choked, the filter module as well as the prefilters and postfilters are removed and cleaned using pressure water pump at about 110bar pressure. The filters are dried using a compressed air jet and repositioned inside the fume extractor. Adequate training was given to the maintenance technicians to handle the equipment. All safety features were explained and demonstrated.

MistKiller™ – Your one stop solution for mist control from water-based coolant

Ever wondered what harm a water-based coolant does to the people on your shopfloor?

A lot of people believe that using a water-based coolant is less harmful than using oil-based coolants.

On the contrary, even water-based coolants use soluble oils to ensure the longevity of the tool life (corrosion resistance, high friction resistance etc.). One characteristic of the commonly used water-based coolant is that they provide an ideal medium for microbial growth with consequent biological contaminants.

Knowing the risk of releasing contaminants into your immediate environment, would you still consider releasing the water-based coolant mist on the shop floor or the immediate outside environment?

Now that you’re aware of the harm it causes, we hope that’s surely not the case!

Introducing to you Powertech’s MistKiller™ unit – Your one stop solution for mist generated from water-based coolants.

Using the simple technique of centrifugal force, this mist collector unit incorporates a pre filter and post filter to ensure efficient filtration of the water-based coolant mist before releasing it into air. The air released is about 80%-90% clean which means there is a substantial reduction of pollutant in the mist.

The centrifugal force inside the unit, condenses the mist to liquid which can be routed back to your machine for re-use by means of a drain pipe.

Pre-filters in the form of Aluminum Mesh and Post Filters in the form of Foam Mesh provide excellent filtration and also are washable and re-usable.

What you get with our MistKiller™ is – 1 unit, 3 major benefits:

  1. Filtration of mist at the mist generation source.
  2. Coolant retrieval for re-use
  3. No replaceable cost of filters as these can be just washed and re-used

Are you in need of a mist collector to capture and control water-based coolant mist from CNC machining operations? Get in Touch with us today and we will work with you to provide the best possible solution for your specific requirements.

Successful Application of FumeKiller® as a Welding Fume Extractor

Introduction:

The FumeKiller® on multiple occasions was able to prove its worth with the effective capture and control of fumes generated from industrial processes. One of the most common processes which has employed the FumeKiller® is in welding. In this post, we look into a project where the FumeKiller® was successfully implemented as a welding fume extractor.

The Challenge: Control of Welding Fumes generated during manufacture and assembly of commercial vehicles.

The customer was an established company in the automotive sector and was faced with a very tricky problem – During the welding process conducted on commercial vehicles like trucks, fumes were generated from multiple points. The fumes were being generated from different points based on where the welding was being done and it was impractical and expensive to create a large extraction hood / station that would be capable of effectively capturing the generated fumes. The customer therefore needed a novel and custom designed solution to ensure successful extraction of the generated welding fumes.

The Solution: Single FumeKiller® model FK3600VEM equipped with Flexible Extractor Arm.

Due to the tricky nature of the problem, our team had to approach the issue with a creative mindset to ensure a viable solution for the same. After careful investigation and study of the workspace(s), we decided that the best solution to the issue would be to use a portable welding fume extractor equipped with a Flexible Extractor Arm and based on our study of the process, it was decided that the FumeKiller® model FK3600VEM would be used for the extraction of welding fumes. Some of the benefits of this solution include:

  • Portable FumeKiller® Unit: The FumeKiller® model FK3600VEM is a vertically oriented variation of the standard model. The unit itself is mounted on wheels and can be moved to different location depending on where the welding process is taking place.
  • Flexible Extractor Arm: Although not a part of our standard line of products, the Flexible Extractor Arm is one that is used specifically in situation like what the client was facing. The arm along with the portable fume extractor, allowed for adjustment of the extraction hood close to the welding point. This therefore, would ensure effective and efficient extraction of the generated welding fumesdirectly from the source, without spreading to the rest of the shopfloor.

Results and Impact:

The implementation of the FumeKiller® was a success which allowed for multiple benefits to our client:

Improvement in Air Quality: Since the fumes that were generated from the process were being extracted directly from the source, the remainder of the shopfloor remained pollution free. The direct result of this was a safer and healthier work environment for the staff.

Operational Efficiency: The FumeKiller® model FK3600VEM is a single portable fume extractor unit that allowed for a mobile extraction system that could be deployed to any location, as and when required. This negated the requirement of a bulky and expensive fume extraction station which may not have provided the same efficiency of extraction. The solution was therefore not only efficient but allowed the customer to benefit from significant cost savings as well.

Regulatory Compliance: The successful implementation of the FumeKiller® as a welding fume extractor resulted in the customer meeting the required air quality standards within the shopfloor.

Conclusion:

The success of the project is a clear example of how we use a unique approach to every single client and provide custom built solution for each requirement. We are committed to providing every customer with the most effective, efficient, and economical solution for their air pollution control needs. With our portable fume extraction system, we were able to address the welding fume issues faced by our customer and help to enhance the air quality and thereby worker safety within the shopfloor. The transformative impact of the FumeKiller® in this project clearly demonstrated its potential to create cleaner and safer workspaces.
