A £105,000 cyclofilter-based dust extraction and wood-fired heating system has been installed at Wolverhampton-based bathroom equipment manufacturer Anotrim Ltd.
Supplied by Wood Waste Control (Engineering) Ltd, it replaces an ageing system which incorporated a cyclone filter that was noisy and prone to vent dust into the atmosphere.
Formerly an aluminium extrusion specialist, much of Anotrim’s turnover now comes from wooden bathroom components including toilet seats, bath panels, cabinets and vanity units. It has a separate factory employing around 100 people on wood production and utilising three CNC routers and a state-of-the-art denibbing machine, as well as saws, routers and spindlers.
The investment in the new system was made to reduce noise levels and make the company both environmentally compliant and a ‘good neighbour’.
The new system has utilised existing fan motors, linking them to a new 4Y7 cyclofilter capable of processing 35,000cfm of waste.
The filter has a filter body diameter of 4m with 154 filter bags, a filter area of 277m2 and a filter velocity of 3.77m a minute.
The filter works on a cyclonic system of separation and the bank of filter sleeves built into the top is cleaned by compressed air whenever pressure is between 40mm and 80mm. The waste discharged is drawn through Wood Waste Control’s WRV100 rotary valve, and then pneumatically transferred via a loop ductwork system to a 25m3 collection silo and on to a 1 million BTU heater system.
