Automatic Vertical Pressure Filter

Automatic Vertical Pressure Filter is ultimate equipment designed to handle flammable, toxic and corrosive material since they are autoclaved and designed for hazardous environment when high pressure and safe environment is required. Like wise they may be readily jacketed for application whenever hot or cold temperature is to be preserved.

  1. Improvement in productivity

  2. Reduction in energy consumption

  3. Superior product Properties

  4. High Yield

  5. Emission avoidance

Scope of application:

  • Pharmaceuticals

  • Food Processing

  • Waste Processing

  • Effluent Treatment

  • Minerals

  • Mineral Concentrates

  • Chemical Processing

Design Features:

  • The horizontal plate design results in even distribution of slurry, wash liquid and most effective air penetration with no risk of cake cracking.

  • Fully automatic. Resulting in consistent performance in terms of through put, i.e. higher productivity. Once downstream and upstream equipment integrated with optimized process parameters leading to highest quality products, with lowest moisture and yield. No operator required, eliminates exposure of operator to chemical & equipment.

  • As the driest cake is produced of all filtration methods, Lower energy costs as it eliminates or reduces the requirement of dryers.

  • Ultra filtration wash system eliminates plant effluent system.

  • The machine can be built with features confirming to explosion proof standards.

  • Based on service requirements non corrosive, corrosive or highly corrosive application, machine can be built with various stainless steels & high strength materials.

Mode of Operation:


With the push of Button, Filter Plates close, closed chambers are formed. Pressurised pumping of slurry into all chambers simultaneously takes place. As filtrate permeates the filter cloth, cakes are formed.


High Pressure water fills all chambers, inflates diaphragm, squeezing the already formed cakes with 4 to 5 times higher pressure than feed pressure. Tightly woven filter cloth allows for higher pressure and increases filter efficiency.

Cake Wash

As the plates are horizontal, wash liquid is evenly distributed for uniform cake washing.

Post Wash Squeezing

High pressure water is pumped in simultaneously to all chambers, squeezing all the wash liquid through cakes with ‘Total displacement’ wash, thus achieving very high efficiency.

Air – Blowing

Compressed air is blown through cakes in all chambers simultaneously through adjusting Pressure & duration of air, further minimizes the moisture.

Cake Discharge & Cloth Washing

All filter plate packs open with advancement of filter cloth all solids are discharged automatically. Both sides of filter cloth is washed with high pressure water to clear the cloth sieves of any binding solids.
