Filter Aids

Precision and Purity

Norcal Perlite’s Filter Aids are a series of high-performance grades designed to enhance filtration processes across various industries. Each grade is specifically engineered to optimize the separation of solids from liquids, ensuring clarity and purity in every application. Explore the unique characteristics of our N-10, NC510, and N-20 grades, and discover how they can elevate your filtration systems to new levels of efficiency.

Our Filter Aid Perlite Products are Food Grade Certified & FCC/Codex Certified.


N-10 Grade: The Fine Filtration Specialist

The N-10 grade stands as our premier choice for fine filtration needs, particularly excelling in rotary vacuums or filter presses. Its exceptionally small and shattered particles are tailored for intricate applications that demand high precision in separating solids from liquids.

N-10’s fine particles construct a formidable cake layer, transferring the filtration workload from the septum to the perlite filter aid itself. This transition allows for efficient trapping of solids while facilitating the clean passage of liquids. In rotary vacuums, it ensures that solids are effectively separated, leaving behind a clear, purified liquid.


N-15 Grade: The Balanced Blend

Our N-15 grade represents a harmonious blend of N-10 and N-20 grades, providing a versatile solution primarily utilized in rotary vacuums. This mixed product is for users seeking a balanced filtration medium that combines the best aspects of both fine and coarse grades.

The key to NC510’s effectiveness is its ability to form a robust cake with ideal integrity. This balance is crucial as every press, application, and operator requires a slightly different approach. The NC510 adapts to these varying needs, offering a tailored cake that maintains its structure while ensuring efficient filtration.


N-20 Grade: The Coarse Clarity Provider

As our coarsest filter media, N-20 is predominantly used in filter presses, especially for wastewater applications. This grade is known for its economical value without compromising on performance.

N-20 utilizes its coarser particles to adeptly facilitate the separation process in filter presses. Its structural integrity allows for a pronounced separation of solids and liquids, resulting in clear filtrate and effective solid retention.
