Product Introduction

The four-foot station provides a practical single-operator negative-pressure work zone with 23 or 30 in interior depth. A remote blower and ductwork draw air into the open face and through a 99.99% HEPA exhaust filter. This configuration is intended to limit dust migration during small weighing tasks while retaining space for a balance and containers.

Key Features

Negative-pressure capture

Inward face airflow directs released powder toward the filtered exhaust path.

Depth selection

A 23 in interior suits compact balances, while 30 in supports deeper instruments and containers.

Remote blower connection

Separating the blower from the work enclosure can reduce local heat and noise.

Applications

For small pharmaceutical powder weighing and sampling with one balance. The suitability of filtered exhaust and duct routing depends on the material hazard assessment and applicable exposure limits.

Solutions for Your Application

Powder released during transfer escapes into the laboratory.Use inward negative-pressure airflow and maintain the specified ducted exhaust rate.

A shallow station cannot fit the balance and source container.Select the 30 in depth after measuring the full operational layout.

Available Options

Choose interior depth, work surface, airflow monitor, sash arrangement, service fixtures and remote blower capacity. Filter handling should match the material risk.
