Key Concepts
There are some foundational terms and definitions central to understanding how filtration systems work. These core concepts are essential for making informed decisions in your process.
Micron Rating
A quantitative measure of filter performance indicating the particle size retention capabilities, expressed in micrometers (µm). Use our interactive guide for real life examples and applications.
Nominal vs. Absolute Filtration
Nominal filtration provides statistical particle removal efficiency, while absolute filtration guarantees removal of all particles above the rated size with validated beta ratios ≥1000.
Filter Media & Types
The material or structure used to capture unwanted particles and contaminants.
- • Depth Media: Tortuous path filtration utilizing multiple mechanisms
- • Surface Media: Direct interception via controlled porosity
- • Membrane Media: Precise molecular weight cut-off and retention
- • Pleated Media: Optimized surface area to volume ratio configuration
Filter Vessels & Housings
In advanced systems, filter media are housed in precision-engineered vessels, including custom cartridge and bag filter systems, as well as specialized strainers. These housings are optimized to minimize pressure drop, control turbulence, and maintain thermal stability, ensuring high performance in demanding industrial environments.
