FACTORY FOCUS DUST & FUME EXTRACTION DOWNFLOW BOOTHS PROTECT OPERATORS
With a high incidence of workplace risk from respiratory sensitising dusts from grains, flour, egg protein, fish protein and ingredient additives, Hosokawa Micron has responded to food industry demands for improved and safer levels of personnel and product protection by developing a range of modular downflow booths. Capable of delivering operator exposure levels of <1µg/m3 the booths provide product protection from surrounding area contamination by creating a ‘clean processing zone’ minimising cross contamination risk from other products or processes. The Hosokawa downflow booths have been designed to meet key demands for energy efficiency, low running cost and operating noise. Their cost effective yet flexible modular design makes them suitable for a range of applications when it is necessary to undertake processing steps outside of a closed food processing machine including sampling, filling or packing operations. The low running costs of the booths can be attributed in part to the incorporation of highly effective and energy efficient motors and fans. Designed to deliver a quick and cost effective route to
contained processing and operator protection without the need for restrictive PPE equipment, the downflow booths deliver a uni- directional flow of air forced downward through ceiling mounted distribution screens in a vertical, laminar flow. This suppresses the elevation of dust, taking it away from the operator’s breathing zone and into the booth’s low level perforated extraction grilles. Thanks to the high density attenuating insulation and quiet running of the motors and fans the modular booths are designed for a noise level of almost 60dba which is less than a normal conversation. This makes them ideal for applications within ‘quiet zones’, within multi-processing areas where acoustic interference would be a problem and when ‘silent running’ is preferable.

A leading global development partner in the avionics and automotive industry offers systems competence regarding internal combustion engines and engine peripherals ranking among the top three systems suppliers worldwide for engine components such as piston systems, cylinder components and valve trains. Problem: Its facility manufactures precision bearings for the automotive industry. There were several issues with
the wet type dust collectors the company was using in its manufacturing area to control the dust from aluminium linishing operations. They were noisy,

inefficient and had to be cleaned out at least once a week. Most importantly, they did not comply with local emissions regulations. Solution: Camfil APC proposed a high tech, custom-designed dust extraction system that would meet all the customer’s demands. Based on a GS16 Farr Gold Series dust collector, as aluminium dust is highly explosive the dust extractor had to be fully ATEX-compliant. The dust collector incorporates an integral drop out section to remove large volumes of dust from the airstream prior to the air passing through the filter cartridges. This reduces the dust
loading on the cartridges, improving filter life. Over 1000 kg per week of collected material discharges from the collector via three rotary valves into 1m3 flexible bags. The GS16 was fitted with carbon impregnated HemiPleat Gold Cone filter cartridges and supplied complete with an access platform and an energy saving variable speed drive controlled by a differential pressure monitor. This system provides highly efficient extraction ensuring that operators are protected from exposure to dust generated during the linishing process. The Scottish Environment Protection Agency (SEPA) has tested the system and concluded that it is an “excellent installation”. The new dust extraction
system has both improved the working environment and reduced maintenance costs. Moreover, production no longer needs to be shut down each week in order to clean the dust collector.

FILTER BENCH FOR DUST AND MIST CONTROL
Specialising in both mist control technology for cnc machine tools and downdraught filter benches for dust control, acs (Air Cleaning Systems) is well positioned to service UK manufacturing industries. Its dust control range includes the FBS downdraught filter bench. This seated version of the filter bench provides an ergonomic and practical solution to the problem of controlling and removing airborne dry dust (or fume) generated by fettling, sanding, deburring, polishing and finishing applications. To achieve reduced running costs, acs supplies as standard an inverter control to regulate the fan speed and reduce power consumption. An optional air control unit enables the operator to work with air-powered tools that automatically power down or up when triggered by the air tool itself. Additionally, the timera offers an automatic power down function after a pre-programmed time interval. The mist control technology range
includes the OMF1000. This freestanding unit is designed to connect directly to a machine tool and incorporates a 2-stage filtration process. Benefits of the OMF range of air cleaners include low maintenance costs owing to a washable pre-filter and long-life HEPA coupled with a 500 watt motor. The OMF1000 is an environmentally friendly, energy saving solution to coolant mist problems. “The marketplace is very
environmentally aware and we are conscious of the needs of our customers as well as our environmental impact,” comments managing director Mark Lemkey. “So with the FBS and OMF ranges we have developed products that offer significant running cost reductions over competitor models while reducing the carbon footprint of acs and its customers.”
