Established in 1969 and now part of the Absolent Group, UK based oil mist removal specialist Filtermist International, is celebrating 50 years in business this year.
As well as being widely recognised for effectively removing oil and coolant mist from workshop air, Filtermist units are also used by many of the world’s leading aqueous parts wash machine manufacturers to capture and contain potentially damaging steam generated in the wash process.
Parts washing applications require the highest standards of both cleanliness and dryness - even the slightest contamination can significantly impair component quality, which in turn can impact on the performance of the machinery which the component ends up in. And it’s not just quality that can suffer – machine operators may also be exposed to airborne contaminants contained within the steam if effective extraction is not used.
Filtermist’s Director of Group UK Sales, Ian Woodward, comments: “Steam and mist produced as a direct result of heating water and detergent to very high temperatures can be contaminated with oil mist particles, swarf and detergent which can be damaging to health. Excessive moisture in the atmosphere can also harm equipment and electrical systems. Whilst many aqueous parts washers offer excellent standards of component drying, the temperatures reached during the wash cycle can result in mist and steam which can lead to condensation and rust, and become a health hazard if not properly addressed.
“As well as being used by a huge number of OEMs worldwide, our units can also be fitted retrospectively – making them ideal for installations where the application may have changed and for incidents where the need for an effective steam and mist extraction system has become apparent over time.”
Filtermist has predominantly focused on working with machine tool manufacturers and operators over its 50-year history, but this year for the first time ever, the company’s German team will be taking part in the Parts2Clean show in Stuttgart to demonstrate Filtermist’s potential in this application.
“Thanks to the fact that we use centrifugal technology, the potential of our products in this market is quite niche”, continues Ian. “The high volume of engineering firms that use aqueous parts washers, rather than solvent based methods, offers an additional opportunity for Filtermist to make a difference to the working environments of a large number of people.”
Filtermist has worked with market-leading component cleaning specialists MecWash for more than 15 years. MecWash’s Managing Director John Pattison says: “Filtermist uses proven technology housed in robust casings that stand the test of time. Some of our customers operate three shifts meaning production is continuous – all elements of our wash systems must be capable of handling 24/7 operation. Where required, we include Filtermist as standard for all clients where a build-up of steam could be an issue. The units are compact, making fitting simple, and their size, location and use of standard consumable parts means they are easy to maintain – making life easier for our clients and ensuring they’re happy with every aspect of the MecWash cleaning system.”
Filtermist units are located on the top of the wash machine, ensuring mist is collected at source before it has the opportunity to permeate throughout the factory. Spinning at a rate of 2850rpm (at 50hz) and 3420rpm (at 60hz), the centrifugal drum collects tiny particles of water and forces them together to form larger droplets which are then collected and removed, or returned to the wash machine depending on the nature of the application. Particles of cleaning agents which could otherwise enter the air are also removed at source, ensuring workers are not exposed to any microscopic particles which could potentially be harmful to their health.
The material used to manufacture extraction units used in parts washing is vital; mild steel Filtermist units can be used in applications where the fluid contains a rust inhibitor – for all other applications, or where legislation dictates the use of stainless steel, such as food production, Filtermist’s entire range can be provided with stainless steel drums and outer casings.
