An Oral Liquid Filter Press is a specialized piece of pharmaceutical equipment used in the production of oral liquids (such as syrups, suspensions, elixirs, and other liquid medications). It ensures crystal-clear filtration by removing solid impurities, undissolved particles, or contaminants from the liquid formulation, meeting strict GMP and FDA standards for purity and safety.

Common Type
The most common type for oral liquids is the Zero Hold-Up Filter Press (also known as Sparkler Filter Press or horizontal plate filter press). This design minimizes product loss by using a reverse flow mechanism—no liquid is “held up” in the system after filtration.
Key Features
-
Stainless steel construction (often SS 316L) for corrosion resistance and easy cleaning.
-
Mounted on a trolley with wheels for mobility.
-
Available in various sizes (e.g., 8″, 14″, 18″, or 24″ diameter plates) depending on batch volume.
-
Often integrated into oral liquid manufacturing plants alongside sugar syrup vessels, mixers, and homogenizers.
Salient Features of Filter Press

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.
