What is a pressure filter?

Pressure filters are filtration systems that force liquids through a filter medium under pressure to separate solids from liquid, producing a clearer filtrate and an effective filter cake.

How do pressure filters work?

They use externally applied pressure to push a slurry or suspension through a filter medium. Liquid passes through while solids are retained and build up as a filter cake.

Where are pressure filters used?

Pressure filters are used in laboratory testing, industrial processing, wastewater treatment and other applications that require reliable solid-liquid separation and dewatering.

What materials are pressure filters made of?

Common construction options include stainless steel 304 and 316, mild steel, and barrel lining options such as PU, PTFE, rubber or ceramic depending on the application and required chemical resistance.

What sizes of pressure filters are available?

LAARMANN pressure filters are available in a standard range of 4 L, 13 L, 24 L and 41 L capacities, depending on the selected configuration.

Pressure filters FAQ (Frequently Asked Questions)

Pressure filters are filtration systems that force liquids through a media under pressure to separate solids from liquid for clearer fluid output and effective dewatering.

They use externally applied pressure to push a suspension through a filter medium; the filtrate passes through while solids form a filter cake.

These filters are used in industrial processes, laboratory environments, wastewater treatment, and anywhere reliable solids-liquid separation is required.

Common materials include stainless steel (304, 316) and lined options (PU, PTFE) for chemical resistance and durability.

Pressure filters come in a range of capacities such as 4 L, 13 L, 24 L, and 41 L to meet diverse application needs.
