This is a laboratory at Wits university, they were experiencing a problem with odor build up and asked Premac to find a solution. We installed balanced extraction ducting connected through a carbon and chemical filter system which vented the filtered air out of the building to atmosphere.
Here is a typical factory with different type of fans, powder coat extraction filter and ducting, all designed, supplied and installed by Premac.
Typical type spray booth for general spray painting, we installed a double sided filter spray extraction plenum with flame proof fan.
In this example we were called in by Bertrand Rochecouste Collet (engineer) for the Aurecon group representing Bethlehem Hydro. For us to design and install a heat extraction system for the two new pollution free hydro power stations being build on the river at Bethlehem, We used a conventional canopy with spiral ducting connected to a Luft axial flow fan.
In this application we installed a SADAC dust collector. The dust collector had to be lifted onto the roof where the installation took place. The collector serves a shot blast booth, We designed and built a raised table to place the item on, to be blast cleaned, while the dust ladened air could then be extracted down past the item into our extraction duct and up throught the roof into the collector.
In this example we designed and installed a dust extractor at the Potchefstroom university's wood work shop, they have an up to date training facility there for teaching students the art of working with wood. The system included point extraction with floor sweep take off points for improved house keeping, the ducting has been sized in order to balance the air flows without the need for dampers while even air flow has been achieved. The dust collector is a manual shake down flow type with collection bin's underneath, the extractor fan has been installed in a separation room to reduce sound breakout.
At Premac we do undertake certain small building jobs. Here we added on a new section to our workshop, the project was approved through a local design draftsman, planning permission was obtained, civil inspections were made by a structural engineer, Premac procured the materials and supervised / managed the building work.
