Product Introduction

The 4 ft configuration provides a practical single-operator workspace for instruments, preparation trays and hand movements. HEPA-filtered air descends at a nominal 45-65 fpm through the work zone, while the 9.4 in sash opening and angled safety-glass front support access. Compared with the 2 ft model, it offers enough lateral room to separate clean components from completed work.

Key Features

Organized work zoning

Four feet of width permits separate incoming, active and completed material areas.

Uniform vertical sweep

Filtered downflow carries incidental particles away from the protected work before air exits the opening.

Ergonomic sash access

The angled hinged sash opens higher for loading while the normal opening limits disruption during work.

Applications

For non-hazardous pharmacy compounding, medical-device assembly, culture-media preparation and electronics inspection. Place tall equipment so it does not block the descending air across critical work.

Solutions for Your Application

The two-foot work zone cannot separate supplies from the active preparation area.Use the four-foot width to establish an orderly left-to-right material sequence.

Tall instruments create a wake in the vertical airflow.Position equipment away from critical items and verify downflow performance after loading.

Available Options

Select UV lighting, airflow monitor, international power, hydraulic or fixed stand and stainless work surface. Process utilities can use the side iris ports.
