ABOUT EQUIPMENT

More examples are being prepared from the technique guide.
If you need a specifc detail, send an email.

The objective of this technique is to stop casting porosity, reliably and efficiently.

The equipment for doing that was drawn from regular standard stock components, from leading compressed air and vacuum equipment manufacturers like:
 Pfeiffer, Northery Technologies, Edwards, Norgren and Parker.

For example, here is the first filter developed. It was possible with practice, to change the element in six seconds.

FILTERS

Filter elements can made be from a variety of materials, but must be rugged, not expensive, and efficient for air flow.

Some ZVAC filters use pleated polyester paper, like in Colmbia, and most use pleated woven stainless steel, like in UK and China etc.

Some woven fabric filters can be used for short duration and dispcarded each day.



Below, is a cross section of a filter that I developed at Dyson Diecasting for protecting the vacuum valves.

The body is from Parker Pneumatics (made in Brazil, imported to UK, customised and re-exported to China).

The filter body, seals and elements need to be resistant to effects of casting release agents and water incombination with metal dusts.

Skimers filters for lifting the oil film off the water that collected in the vacuum pump exhaust condensate waste water tank, were not needed, because it removed by contractor with a bowser.
