Wood Waste Extraction System Relocation

Ducting Express Services Ltd were contacted by one of their existing customers that were relocating to larger premises.

The customer was looking to have some of their existing equipment relocated to be re-used with the addition of new equipment to be installed to meet the increase in production.

Our remit was most importantly to ensure all equipment complies with HSG258 guidelines regulations and to minimise production down time. This was achieved through forward planning and keeping in regular contact with the customer and their other contractors.

Following from our site survey, a new design was proposed. This included extraction to various wood working machines and a large spray booth.

Existing layout

The system in the diagram above was moved from the customers old joinery workshop and re-installed within the new premises.

Most of the spiral ducting from the original site was replaced with Nordfab clipped ducting, this was an investment that will certainly pay dividends. The Nordfab Quick Fit ducting, having a smoother internal surface, and the new duct work design have increased the performance of this extraction system due to less resistance.

Using Nordfab QF ducting also means that, if, in the future any parts require replacement the components can be simply unclipped and a replacement part clipped back in.

Better airflow has also ensured the conveying velocities within the duct system not only meets, but exceeds the minimum levels set out by the HSE and they were able to add an extra machine to this system.

As you can see in the drawing, this system extracts from spindle moulders, a tenoner, sanding benches, belt sanders, a lathe, a router, cross cut saws, a planer, a 4-sided planer & a CNC machine.

A smaller wood waste extraction system (pictured below) was installed as an either-or system allowing any 3 machines to be used at one time.

This was achieved by installing manually operated blast gate dampers which allow users to close off machines not in use, thus providing the required extraction to only the wood working machine/s being used.

We did discuss the future option of automating this further using pneumatic blast gate dampers directly wired into the machines to remove the risk of any operatives attempting to run the system with too many extraction points open at once.

New layout

To minimise any potential production down time a second standby filter was installed. Should the main wood waste extraction filter fail an operator can simply press a button to operate the pneumatic diverter valve and start the standby. This then diverts the wood waste to the standby filter.

Two spray booths were removed from the customers’ old site and re-installed at the new premises. The addition of a new belt driven axial fan and 630mm diameter spiral ducting allows the customer to safely extract the fumes created within their process. The spiral ductwork terminates externally with a Swedish weather cowl. We also supplied the customer with new spray booth paper pleated filter media.

On completion of the relocation and additions our commissioning engineer conducted a LEV COSHH test to provide the customer with certification for their health and safety records.
