Operations Manager, Chris Halliday, examines finish quality of a speaker cabinet.

DCS had to install the NFKZ2000 modular chain filter in very limited space.


Sheffield-based Oakwood Cabinets, the UK’s premier manufacturers of loudspeaker cabinets, has recently invested in a new dust extraction plant from Dust Control Systems. The installation is part of a complete ‘waste-for- energy’ system designed to deal with the company’s increasing levels of woodwaste, whilst saving energy and reducing costs.

With a heritage of cabinet making stretching back over 200 years, today’s skilled workforce at Oakwood carry on the tradition of craftsmanship by fashioning superb quality veneered and sprayed cabinets for leading loudspeaker manufacturers worldwide.

Oakwood Cabinets has an annual turnover of around £1.3 million and is part of REL Acoustics Ltd of Bridgend who specialise in the design and manufacture of high-end sub-bass systems. REL take around 15% of Oakwood’s output for their own amplifier cabinets.

Established in a totally refurbished 12,000 sq.ft. facility, Oakwood employs 38 people who contribute to the production of around 2500 high quality cabinets a month in a variety of sizes, shapes and finishes.

“Recent investments in new machinery meant we had outgrown our existing dust plant”, explains Operations Manager Chris Halliday. “It was time to replace it with a more efficient system and we decided that we should also investigate the viability of installing a wood-burning heater that would save both energy and waste disposal costs”.

Working in close cooperation, Dust Control Systems and Talbott’s Heating installed a system that provides efficient and quiet dust extraction together with a self-sufficient wood burning system.

The new dust extraction system comprises an NFKZ2000 modular chain filter, complete with low power elevating conveyor, which transfers woodwaste, pressure free, into the burner silo. The filter unit and wood-fuelled heater had to be installed in very limited space between a perimeter fence and the workshop, leaving enough space for forklift access.

The high-efficiency filter is designed to handle an airflow capacity of 46,000m3/hr and is certified according to the latest ATEX directive. Extracting from a variety of woodworking machinery, including CNC Routers, the system also includes a series of custom-designed extraction hoods for specialist routing stations. Low-noise fansets quietly go about their business helping to create a much cleaner and quieter workshop environment.

Sawdust and woodwaste provide fuel to heat the facility at virtually no cost. And, like a growing number of furniture and joinery manufacturers Oakwood Cabinets were able to fund most of the scheme with the aid of a government grant based on energy saving.
