What We Offer

World-class plant and lab pressure filters that operators love to use

“If we get more filters like that [the Essa CPF015] to replace the other filters, I will not take a vacation for six months.”

It’s not often you hear lab operators praise pressure filters. Traditionally they have not been the most pleasant device to use in the met lab or plant. Bending to load and unload. Manually tightening plates. Difficult to access filter cakes. The ever-present threat of slurry violently escaping under high-pressure.

The Essa pressure filter range was redesigned to make the filters among the safest in the industry to use. But they had to be trouble-free and easy to use too.

“It is ergonomically friendly”

“There is no need for excessive bending over to tighten items down”

“Drainage is upfront as opposed to the rear”

“The gaskets seat up inside the lid, in case of pressure release sample will go down as oppose to straight at you or towards the ceiling”

“No tools needed to tighten it down”

“It looks intimidating at first to use, but once you know how to use it, there is no going back to the other filters”

Operator feedback suggests this goal was achieved.

But what was bad? “We don’t have more of them”.

Why completely redesign the pressure filters?

Safety is paramount in any industry. When batch pressure filters were put under the spotlight in 2015 by the Government of Western Australia as posing a risk to mine safety, the response was quick. Although the existing Essa Pressure Filter design was not considered to pose safety risks beyond those expected with this type of equipment, the filters were redesigned to a higher safety standard.

The filters were redesigned to meet the revised requirements of authorities and regulatory bodies around the world. Metallurgical process specialists and product engineers worked with a firm of independent engineers to improve the design in terms of safety, ergonomics, productivity and longevity. User feedback was also valuable to make sure the usual challenges of operating pressure filters would become a thing of the past.

The new Essa® Certified Pressure Filters are designed to be safe and easy to use.
