Air Filtration Systems in Modular Cleanrooms
Types, Features, and Specifications for Optimal Air Purity
Ensuring pristine air quality in modular cleanrooms is a multi-faceted process involving sophisticated air filtration systems. These systems employ various filters to achieve optimal air purity, playing a crucial role in industries like pharmaceuticals and Electronics. This guide categorizes the types of filters used, detailing their features and specifications, with insights from Deiiang™ and design expertise from product designer Deiiang Jason.peng.
Primary Pre-Filters
The First Barrier Against Contamination
As the initial line of defense, primary pre-filters play a crucial role in capturing larger particles, preventing them from reaching more sensitive downstream filters and extending their lifespan.
Features
- Durable fiber construction for high particle load handling
- Robust design to withstand continuous use
- Efficiency in removing larger debris effectively
Specifications
| Standard | Efficiency |
|---|---|
| ASHRAE | MERV 1-4 |
Medium Filters
Enhancing Air Quality Further
As the secondary layer, these filters target smaller particles that bypass the primary filters, providing a crucial middle step in the multi-tiered filtration process.
Features
- Balanced airflow and resistance design
- Suitable for moderate to high air quality environments
- Effective particulate reduction capabilities
Specifications
| Standard | Efficiency Range |
|---|---|
| ASHRAE | MERV 8-14 |
HEPA Filters
Superior Performance for High Purity
Critical for environments requiring high air purity, HEPA filters set the standard for capturing fine particles, ensuring Clean air delivery in sensitive applications.
Features
- Pleated media for maximum surface area
- High filtration efficiency with low pressure drop
