Filtermist launches F Save to cut energy usage by 80%

Telford-based Filtermist Ltd, one of the world’s leading oil mist extraction specialists has introduced new technology that can help manufacturers improve their environmental performance by significantly cutting energy costs on machine tools by up to 80%. The company, which supplies customers in more than 60 different countries worldwide, officially launched the new product at EMO Hannover 2025.

F Save has been designed to optimise the operation of the company’s oil mist collectors, meaning the unit only runs when it is needed rather than constantly being on throughout a full shift — whether the machine tool is being used or not. The smart system includes a sensor which attaches to the coolant pump on the machine tool and communicates with the F Save Hub. If the pump is inactive, the Filtermist unit automatically switches off.

René Joppi, managing director at Filtermist, said: “Our research showed that some machines are only operational for around 20-30% of the working day. If our unit runs constantly during this time, it wastes resources, increases costs, and adds to a company’s carbon footprint. With F Save, customers can cut energy usage by up to 80% and in some cases, achieve payback in under three months. Only using the Filtermist unit when it is required has a significant impact — not just on sustainability, but on operating costs too.”

Reduces waste energy
As oil mist is only generated when coolant is in use, this reduces wasted energy while keeping machine operators fully protected from exposure to airborne oil mist particles. Designed for quick installation, F Save does not require any electrical interfacing with the machine tool, making it simple to retrofit to existing units. It also removes the risk of operators forgetting to switch the unit on or off, ensuring workplaces remain clean and safe.

The pre-study of this technology was led by applications engineer Krzysztof Kaszuba. He concluded: “Our research shows that, on average, a machine tool is only cutting parts for about 50% of its operating time. The rest is taken up by tool changes, part changes, or similar activities. F Save prevents energy from being wasted during these periods, offering thousands of customers worldwide a simple and effective way to cut energy use without compromising safety.”

Filtermist, which is part of the Swedish-based Absolent Air Care Group, provides an extensive range of products and services designed to remove contaminants, such as oil mist, oil smoke, dust and fume from the air in production facilities.

In the UK, the company offers a turnkey service that includes initial consultation and project planning, extraction system design, specification, equipment manufacturer and supply, installation and commissioning, as well as a wide range of aftermarket services such as servicing, maintenance and LEV testing. F Save is available now through Filtermist and its global network of approved distributors.
