Guildford Grammar School - upgrade to D&T dust collection system


The D&T wood-working department at Guildford Grammar School (GGS) had an old and undersized cyclone dust collection system in place.

It badly needed upgrading and new ductwork to suit all the machines in the wood-working workshops. Dynamic Engineering Australia initially reviewed this system in 2019, and the school was able to secure funding for this new system this year.


This project required the supply and install of a new mechanical shaker dust collector, that included an explosion panel and roof-mounted direct drive fan. A completely new ductwork system was also required, with bast gates at each pick up point and incorporating an in-duct explosion valve.

A customised control system and variable speed drive for the collector fan motor was also supplied and commissioned.

As part of the project, Dynamic Engineering coordinated the complete demolition of the old system, and completed the new system installation over the two-week July holiday period, so that the school was able to start the new term with a new operational system.


David York, GGS’ facility manager, was happy with how smoothly the project ran, and the operation of this system.
