Durco Filters Vertical Pressure Leaf Filters are ideal for batch process applications requiring high flow rates with low solids removal in a small footprint. The vertical vessel orientation is used when space is restricted or when interruptable flow is expected. Our filters are custom built & optimized for each application, and are specifically engineeered to operate with the minimum amount of maintenance.

There are three basic vertical pressure leaf models:

Dry Cake Discharge (Type DV)

• Used when cake either needs to be recovered or when cake can be disposed of as a solid
• Commonly uses a Quick Open Closure (QOC) on both top and bottom to facilitate cake discharge and filter leaf access

Wet Cake Discharge (Type V)

• Used when cake can be disposed of as a liquid
• Cake can be sent to filter press for dewatering
• DuraSluice^TM sluicing system washes cake from leaves using a rotating spray header

Horizontal Leaf (Type VH)

• Used when flow is intermittant or interruptable
• Cake is formed only on top surface of circular leaf
• Gravity holds the cake in place during low or zero flow conditions
• Cake is washed/sluiced from the leaves
• A tailings leaf can be included in the bottom of the vessel

Space Saving Design

• Vertical vessel uses less floor space
• Easily mounted in platform
• Maximum filtration area

Permanent Filter Leaves

• No replaceable media for lower operating costs
• Metal screen or polypropylene plastic with cloth coverings and pre-coated to achieve sub-micron retention
• Leaves attach to an outlet manifold with a gasket and O-ring ensuring no bypass
