A leading name in the manufacture of cable glands was experiencing ongoing problems with its existing centrifugal type oil mist filters. Due to the nature of the machining process large quantities of brass fines were being extracted with the oil mist, causing blockage problems within the filter units. The client selected Multi Fan Systems to design and install a more technically advanced oil mist extraction system.
MULTI-FAN SYSTEMS SOLUTION
Multi Fan Systems installed a single filter unit with integral fan, capable of extracting and filtering oil mist from each of four Gnutti machines via separate dedicated extraction lines. Each line incorporates a control valve, actuated via a signal from the machine door, so providing extraction from the machine only when required (ie when the access door is opened) rather than during the cutting process.
This control feature prevents swarf being inadvertently drawn into the filtration system. In addition and as a back-up, drop out boxes are provided in front of the filter unit to capture any swarf that might find its' way into the system. The cleaned air (having passed through the integral HEPA final stage) is returned directly into the production area.
