Product Introduction

The 24 x 26 x 24 in interior provides a deeper transfer shelf than the compact HEPA model and uses self-contained ULPA recirculation for more demanding particle control. Flush wall mounting reduces projections into the clean space, while 304 or 316L stainless construction can be matched to cleaning chemistry. Service access for the fan and filter must remain available after wall integration.

Key Features

Deeper tray accommodation

The 26 in depth supports larger process carriers while preserving a two-foot nominal opening.

Fine-particle filtration option

ULPA media serves transfers that specify a higher removal class than the compact HEPA configuration.

Clean-side flush fit

The installation can align the cabinet face with the finished partition to reduce room obstructions.

Applications

For pharmaceutical and semiconductor material transfer where a medium tray envelope and active fine-particle cleanup are required. Verify that load height does not block the internal air path and that wall framing supports the service module.

Solutions for Your Application

A deep tray blocks return airflow and extends chamber recovery.Define load placement that preserves circulation openings and confirm recovery during commissioning.

Filter replacement would disturb the cleanroom finish.Orient the service side toward an accessible technical space before fixing the flush wall trim.

Available Options

Choose 304 or 316L chamber, interlock logic, purge timer, filter alarm and door access controls. Final ULPA grade and test method should follow the site's transfer risk assessment.
