Product Introduction

This compact B2 model sends all cabinet air to the facility exhaust rather than recirculating it to the room. The 1379 mm exterior width provides a focused work zone for suitable volatile or hazardous procedures while limiting the footprint and exhaust demand relative to the six-foot unit.

Key Features

No room recirculation

All cabinet airflow leaves through the hard-duct exhaust route.

Defined duct interface

A dedicated 254 mm connection supports facility system planning.

Compact B2 footprint

The four-foot format suits focused processes that do not need the 1800 mm work width.
