Filter Baskets

These components, known as filter baskets, are essential for optimising product yield during filtration and drying processes. They are crucial to filter dryer systems used in the pharmaceutical, fine chemical, and other specialised industries to separate solids from liquids under vacuum conditions.

Filter baskets are cylindrical containers with perforated surfaces, designed to securely hold filtration media. Their main function is to allow liquids to pass through while retaining solid particles, effectively separating the two phases during processing. Their design and material ensure efficient and reliable filtration, which is vital for maintaining product purity and consistency.

What are they used for?

The primary role of the filter basket is to hold the filtration media in place. This allows for efficient separation of solids from liquids, ensuring that only the desired product is collected while impurities are filtered out.

This filter basket is designed to be easily removed from the main vessel. This feature simplifies the process of collecting the final product, reducing downtime and improving productivity.

The filter basket supports quick and easy changeover of filtration meshes with various pore sizes and materials. This flexibility allows the system to handle different products and filtration requirements, making it adaptable for multi-product applications.

What are they made from?

The material selection for the filter basket is critical to its performance and durability. Here are the reasons why specific materials are used:

Polypropylene (PP): Polypropylene is chosen for its excellent chemical resistance, lightweight nature, and cost-effectiveness. It is suitable for handling a wide range of chemicals without degrading, making it ideal for processes involving aggressive substances.

PTFE (Polytetrafluoroethylene): Virgin PTFE Polytetrafluoroethylene is known for its superior non-stick properties and high chemical resistance. It can withstand high temperatures and is resistant to most solvents, acids, and bases. This makes it an excellent choice for applications requiring stringent chemical compatibility.
