Industrial Filtration Solutions: Driving Efficiency and Precision
Filtration technology plays a critical role in modern manufacturing and machining environments. By ensuring cleaner fluids, businesses can achieve superior precision, reduce operational costs, and minimise environmental impact.
In industries where cutting, grinding, and machining are core processes, fluid cleanliness directly impacts product quality and equipment longevity. Traditional filtration methods often rely on consumable filters, leading to recurring costs and waste. Advanced magnetic and automated filtration systems offer a smarter alternative, delivering cleaner fluids and significant cost savings. This whitepaper explores the benefits of advanced magnetic filtration and how it contributes to sustainable and profitable operations.
How to Reduce Costs with a Magnetic Filter
Magnetic filtration systems are cable of removing ferrous and paramagnetic particles as small as one micron from oil, coolant and lubricants during the machining process. These filters also inhibit bacterial growth because they extract contaminants without impacting the anti-foaming and anti-bacterial properties of the fluid. This extends the life of the fluid allowing for a reduction in fluid replacement. 
Additionally, the cleaner coolant or oil means less damage to the machinery and tools due to dirty fluid. Meaning you save money from fewer repairs and product defaults caused by metal particles circulating your system.
These systems often pay for themselves within weeks, driven by lower fluid waste and downtime costs.
Furthermore, if you employ an automated filter, such as Eclipse Magnetics’ Autofiltrex, your machines can run 24/7 as the magnetic filter is capable of self-cleaning at programmable times. The resultant contamination is caught in the integrated waste reclaim and fluid recovery system, significantly reducing machine downtime and additional labour to clean the industrial filter.
Decrease Your Waste with a Magnetic Coolant Filter
Switching from a consumable filter such as paper, bags or cartridges to a magnetic filter means significant cost savings on purchasing regular replacement filters.
Minimise fluid loss with an eco-friendly filtration system, ferrous debris collects as a semi-dry cake, shrinking fluid loss and associated disposal fees compared to a traditional media filter. The contaminants are clean enough for recycling, reducing hazardous waste disposal costs. Significant reduction in fluid and filter waste supports sustainability initiatives like ISO 14001.
Magnetic filters requiring manual cleaning have no consumable parts and automated variants use minimal power during operation.

FAQs
Why is advanced magnetic filtration more effective than traditional filtration techniques?
Magnetic filters are very advanced when compared to traditional magnetic applications to remove ferrous particles. In the past, magnetic systems were very basic, often consisting of randomly placed low strength magnetic bars or rods in a settlement tank, or a low strength magnetic roll. Unfortunately, the results are largely ineffective.
Whilst the basic principles of magnetic filtration are similar, there are huge differences in the product design and levels of performance between advanced magnetic filters and the magnetic systems of the past.
How does magnetic filtration increase productivity?
Magnetic filtration increases productivity in variety of ways. High flow rates can be maintained without affecting filtration efficiency. Fluid does not flow through filter media, so flow is uninterrupted. Flow rates are, therefore, determined by your process requirements, not by your filter.
There’s also no back pressure when a magnetic filter is used. Even when the filter is ‘full’ there is no blinding or risk of burst filters, reducing downtime.
Eclipse Magnetics produce a wide range of magnetic filters for a range of industries from steel processing to bearing manufacturing. Each filter has its own unique properties whilst providing a cost-effective and environmentally friendly solution to removing fine ferrous particles from machine coolant.

Can magnetic filtration help me to comply with the New Safe Handling of Metalworking Fluid Guidelines?
Yes, including a magnetic filter in your metalworking fluid system is a great way of ensuring that your business is compliant with the new guidelines for the Safe Handling and Disposal of Metalworking Fluids introduced by The United Kingdom Lubricants Association (UKLA).
Metal contamination has been identified by the UKLA, the Metalworking Fluid Product Stewardship Group (MWFPSG), and the Health and Safety Executive (HSE), as a major factor affecting the quality of metalworking fluids. In order to ensure compliance with the safe handling and disposal of metalworking fluid guidelines, fluid needs to be correctly maintained with regards to the concentration of metal contaminants in the fluid. Magnetic filtration is a very effective way of reducing the concentration of metal contaminants, therefore ensuring compliance with the metalworking fluid handling guidelines.

Why use magnetic filtration over traditional filter methods?
Magnetic filters are more effective at removing ferrous particles than virtually all other types of filtration. Traditional barrier filters are constrained by the pore size in the barrier; if the pore is too big, the contamination continues to circulate; but if it is too small, it will block. Whilst centrifugal filters work well for mixed contaminants, including non-ferrous particles, they can be costly upfront and may not be as efficient for fine ferrous particles as magnetic filters.
Advanced magnetic filtration has been specifically developed to overcome some of the typical problems experienced when using traditional filters. Fully automated magnetic filtration systems an effective solution for continuous manufacturing lines, offering 24/7 uninterrupted filtration and resulting in minimal downtime.
