An SS 316 Filter Press (Stainless Steel 316 filter press) is a specialized industrial solid-liquid separation equipment constructed primarily from AISI 316 (or 316L) grade stainless steel. This material is an austenitic stainless steel alloy containing chromium, nickel, and molybdenum (typically 16-18% Cr, 10-14% Ni, 2-3% Mo), which provides superior corrosion resistance compared to SS 304, especially against chlorides, acids, and pitting in aggressive environments.

Key Features and Construction
-
Material: Plates, frames, and often the entire structure (including head, tail, and side bars) are made of SS 316/316L for durability, hygiene, and resistance to harsh chemicals.
-
Types: Commonly available as plate and frame (alternating plates and frames for larger cake capacity) or recessed chamber (recessed plates forming chambers directly).
-
Operation: Hydraulic or manual closing mechanism presses the plates together. Slurry is pumped into chambers, filtrate passes through filter cloths/media, and solids form a dry cake.
-
Customization: Sizes vary, with options for gasketed/polished plates, automatic cake discharge, and GMP-compliant designs.
-
Pressure Rating: Typically handles high pressures, suitable for demanding filtration.
Advantages of SS 316 Material
-
Excellent Corrosion Resistance: Molybdenum addition enhances resistance to pitting, crevice corrosion, and acids, seawater, and chlorides—ideal for corrosive slurries.
-
Hygienic and Sanitary: Polished surfaces meet GMP standards; non-contaminating for food/pharma.
-
High Temperature & Pressure Tolerance: Withstands elevated temperatures and rigorous conditions without degradation.
-
Long Service Life: Durable, modular design allows scaling; easy maintenance with automatic features.
-
Compared to PP or Cast Iron Presses: Better for corrosive/hygienic applications where plastic may fail or iron may contaminate.
Applications
-
Pharmaceuticals: Sterile filtration, API production.
-
Food & Beverage: Juices, wines, oils, dairy—ensures purity and hygiene.
-
Chemicals: Corrosive slurries, dyes, paints.
-
Distilleries, Oils, Paints, Wastewater: Where corrosion resistance is critical.

Process Operation of Filter Machine
The liquid is fed into the filter of the machine and it is done under positive pressure. Now, the liquid travels downwards and passes through the opening on the sides of filter plates. The filter media holds back foreign particles and enables only clear filtrate to go past the central channel. This central channel is made by interlocking pressure cups to the outlet. The filtration process continues until the cake holding capacity gets saturated or the filtrate rate gets way slower than it must be. This happens due to decreasing cake resistance.
Our meticulously designed filter press is cost-efficient. And you can bet on its efficiency – it helps save every precious drop.

Note:
- The flow rate is mentioned in terms of water with 5% activated carbon with filter media as polypropylene cloth.
- Filtration rated depends on viscosity of liquids, quality of filter pads and nature of sediments in liquid to be filtered.
