Giới thiệu Sản phẩm

This configuration dedicates all three stages to particles: a 2 in coarse panel, a 12 in secondary filter and a final HEPA. The progressive sequence is intended for outside-air systems with enough dust load to justify two protective stages before the expensive final filter. Unlike the molecular version, it does not include a gas adsorber; its benefit is longer HEPA life and more stable particle capture under heavy ambient loading.

Các tính năng chính

Progressive dust capture

Each upstream stage removes a different particle fraction before air reaches the HEPA.

Extended final-filter life

The secondary deep filter absorbs loading that would otherwise raise HEPA resistance prematurely.

Modular matched sections

Welded side-access housings align the three filters and allow separate service for each stage.

Applications

For cleanroom make-up systems and critical facility AHUs exposed to high outdoor dust, seasonal pollen or industrial particulate loading.

Solutions for Your Application

The secondary filter is too coarse to materially protect the HEPA.Select a progressive efficiency step that captures the dominant fine-dust fraction without exhausting the system pressure budget.
Maintenance changes all three stages at the same interval and wastes usable filters.Provide differential-pressure points across each section and replace stages according to their individual loading.
