Product Information Leaf Filter

Leaf Filter


  • CFR type

    CFR type

    Horizontal type filter which discharges the cake as dried solid
    IHI Leaf Filter Standard type capable of drying filtrated cake by steam, air and N2 gas, and discharging it automatically.
  • CFA type

    CFA type

    Horizontal type filter which discharges the cake as slurry
    The fundamental structure of the CFA type is the same as that of the CFR type. As well, this type is capable of reslurry-discharge by back washing.
  • LR type

    LR type

    LR Filter
    The performance of the LR type is the same as that of the CFR type. As well, this type is a filter for Dreg Removal and is easily capable of CIP Automatic Washing. It is suitable for Food, Chemicals, Medicines and Pharmaceuticals.

IHI is proud of this newest Fully Automatic Filter.

This LR type Leaf Filter is a Horizontal Filter Leaf type Pressure Filter. Inside the pressure-resistant vessel, filter leaves are arranged horizontally on the shaft. A motor drive rotates the shaft and cakes on the leaves are blown away by centrifugal force.

Rest Volume Filtration System

No residual liquid is left; there is complete filtration. The IHI Leaf Filter, CFR type and CFA type, performs Rest Volume Filtration using all the leaves, which enables complete filtration. This system has made it easier to treat several types of materials with a single machine.

  • Speedy

    Using the entire area of all the leaves, less time is required.

  • Constant Rate Cake Forming

    Using the entire area of all the leaves, cake is formed constantly.

* Final rest volume after Rest Volume Filtration is a very small amount of liquid at the final stage and residues in a line or a pump.

Cake Removal by Horizontal Filter Leaf Rotation

The filter nests rotate when cakes are discharged. The cakes on the leaves are blown away by centrifugal force.

Cleaning Nozzle

When removing cakes on the leaves, the surface and inside of the filters are washed at the same time.
