Product Introduction

The 800 mm cubic work zone is paired with a 1020 x 860 x 1350 mm external envelope and 210 kg welded body. Unlike the 400 and 600 mm versions, this model uses a 0.3 kW air package and two 20 W UV lamps to serve the larger volume while maintaining the same rated unidirectional velocity. It is intended for sizable assemblies and sealed bins that need positive-pressure filtered transfer rather than simple passive passage.

Key Features

Bulky clean-load volume

The 800 mm chamber gives process assemblies and large material bins handling clearance unavailable in the smaller row.

Upsized airflow duty

A 0.3 kW package supports the larger chamber at the published 0.45 m/s airflow basis.

Heavy welded construction

The 210 kg stainless enclosure provides a seamless cleanable work zone but requires deliberate structural support and handling.

Applications

For large sealed material bins, process fixtures and assemblies crossing pharmaceutical, biotechnology and medical-device cleanroom boundaries. Procurement should check floor or wall support for the 210 kg enclosure, load reach distance, filter replacement clearance and the effect of shelving on airflow.

Solutions for Your Application

Large assemblies cannot be loaded into the 600 mm chamber without contact or disassembly.Use the 800 mm cube to provide additional clearance and keep the assembly intact through the transfer cycle.

A larger active box increases structural and maintenance demands that are missed during wall planning.Reserve support for the 210 kg cabinet and service access around the taller 1350 mm air-handling enclosure.

Available Options

Choose stainless grade, door count and orientation, electronic controls, access interface and removable storage accessories. Confirm the maximum load mass, airflow qualification method and material compatibility with UV exposure.
