Sample Dewatering: Pressure Filters & Vacuum Filters

 

MARC Technologies Manufactures and Supplies a wide range of pressure filters in bench mount or floor standing configurations.

 

Please Read: *In September 2015 the Government of Western Australia’s Department of Mining and Petroleum (DMP) issued a reminder that Laboratory Pressure Filters are to be designed and treated as Pressure Vessels (Click Here to Read).*

Although the term “filter press” is commonly used for this equipment this is actually incorrect – the correct term is “Pressure Filter” and it should not be forgotten that these are pressurized systems. The average pressure filter cannot be cost effectively modified to comply with AS 1210 as there are a few key structural changes required and the pressure filters commonly used in mineral sample processing applications have not in any way been designed to comply with AS 1210. 

 

Quick & Easy Handling – High Performance Certified AS 1210 Compliant Pressure Filter

 

High Performance AS 1210 Pressure Filter

 

Main Features:

  • 6 and 13L Sample Volume Options
  • Rapid Dewatering Design (Up to 80% faster filtering than competitor products)
  • AS 1210 Compliant
  • Corrosion Resistant 316 Stainless Steel Construction  
  • Filter cloth clamping time: ~3 seconds (depending on operator experience)
  • Time to close and pressurise: ~2 seconds 
  • Removable filter cake support is supplied as standard 
  • Filter media clamping force is easily adjustable in seconds.

 

Please also note MARC’s pressure filter is designed to be operated at 500 kPa and is designed for a maximum sample hazard classification of “Harmful liquid and/or Gas”. This covers gold/cyanide applications.

Floor Mounted Pressure Filters (Not AS 1210 Compliant)

 

MARC 24L FM Pressure Filter_Red

24L Floor Mount Pressure Filter with Mild Steel Frame

 

 

5L Floor Mount Pressure Filter with 316 Stainless Steel Frame

 

The floor mounted pressure filters are available with Mild Steel or 316SS frames. The Barrels are available in 304SS or 316SS.

*Note: Stainless Steel frames do have a higher cost but they dramatically extend the life of the filter – especially when processing low pH samples and metal sulfides. 

We also supply filter cloths and kraft filter paper as consumables for our filters.

Bench Mounted Pressure Filters (Not AS 1210 Compliant)

 

 bench-top-pressure-filter-13lThe bench mounted pressure filters are available with Mild Steel, 304SS or 316SS frames. The Barrels are available in 304SS or 316SS.

It is best to keep the bench mounted filters to a smaller size as the cylinders are manually lifted.

Bench Mounted Vacuum Filter 

 

vac-filter

The bench mounted vacuum filter is available for filtering up to 6L of slurry. Barrels are available in 304SS or 316SS.  Vacuum and filtrate reservoir options are available. Vacuum can be generated via a typical electrical vacuum pump or generated pneumatically via a simple compressed air supply.
