Vertical Pressure Leaf Filter Unit
The vertical pressure leaf filter is an enclosed filtration system and can be fully automated. This unit is autonomous and equipped with all auxiliaries necessary for excellent filtration results. The filter leaves are individually mounted on the central manifold, which allows easy and quick removal of some or all of the filter leaves.
For cleaning it’s not necessary to remove the filter leaves, this can be done even without opening the filter vessel, with our semi-automatic cleaning. We also offer manual cleaning.
We also offer diatomaceous earth for effective filtration of completion fluids, waste water, produced water, work-over and gravel pack fluids.
The vertical pressure leaf filters are available in various sizes from 400 to 1600 sq. ft. and can also be combined with dual cartridges or a bag filter in the unit. The compact footprint has many advantages over the filter press. The pump and mixing tanks are completely built into the frame.

FAQ
What is a vertical pressure leaf filter?
A vessel containing multiple vertical filter leaves for solid-liquid separation, the leaves are full stainless steel or covered with a filter cloth, often polypropylene.
How does it operate?
Slurry enters through inlet at the bottom, solids deposit on leaves, and filtrate exits through the leaves and into a manfold. Cake is discharged by vibration (dry) or backwash (wet).
What applications is it used in?
Used in completion fluids, edible oils, brines, produced water, and chemical processes.
What capacity is typical?
Systems range from 5 m³/h pilot units to over 200 m³/h industrial units.
What pressure/temperature ratings are available?
Standard units operate up to 7/10 bar and 150°C.
What materials are available?
Carbon steel, stainless steel 316, or duplex stainless steels are available.
What filter media is used?
Filter mesh (24×110 or 60) or mesh with a polypropylene, polyester, PTFE cloth
How is the cake discharged?
Cake is removed via vibration (dry discharge) or wash down (wet cake discharge).
What are the advantages vs. cartridge filters?
They offer lower operating costs for high-solid streams and reusable leaves.
What is the main benefit?
It provides efficient large-volume with high solid content filtration with reusable elements.
