Product Introduction

This model pairs the minimum 30 x 50.5 in suspended footprint with the manufacturer's optional ULPA final filter. The published ULPA option provides 99.999% efficiency at 0.12 µm, compared with the standard HEPA configuration. Front access to the filter, blower and lighting supports localized ultra-clean protection above equipment where ceiling-side service is impractical.

Key Features

Higher-efficiency final filter

The ULPA option targets finer particles than the standard 99.99% at 0.3 µm HEPA selection.

Localized ultra-clean zone

The compact module concentrates filtered downflow above a sensitive instrument instead of treating excess floor area.

Accessible maintenance

Front service avoids dependence on an accessible ceiling plenum for filter and blower work.

Applications

For compact semiconductor, micro-optics and precision-device processes where the selected contamination strategy calls for ULPA rather than HEPA filtration. Final cleanliness depends on coverage, room background, load geometry and operating airflow.

Solutions for Your Application

The standard HEPA option does not meet the process particle-removal target.Select the published ULPA filter option and verify system airflow with the higher-resistance filter installed.

ULPA service would normally require access above a tightly packed ceiling.Use the front-service configuration and reserve a clear maintenance approach from the process side.

Available Options

Configure stainless or painted housing, prefilter location, light diffuser, power cord and international power. Suspension and frame details can be matched to the protected equipment.
