Product Introduction

The 4100 x 2900 mm model has the largest listed front-size and airflow duty in the series. Approximately 13000 m³/h of H14-filtered downflow serves the broad process zone, while about 1600 m³/h is exhausted and the remainder recirculates through the rear wall. G3 or G4 prefilters protect the final filters during high-volume powder work.

Key Features

Pallet-scale work zone

The large footprint accommodates vessels, pallets and more than one defined operator position.

Highest series airflow

The 13000 m³/h duty supports the broad open containment face.

Coarse-particle protection

G3 or G4 prefilters extend H14 service life during dusty operations.

Applications

For large vessels, pallet-scale powder handling and multi-operator operations. The full equipment layout must be included in airflow commissioning to identify downflow shadows.

Solutions for Your Application

Large vessels extend outside the protected footprint of smaller booths.Use the 4100 x 2900 mm front size to contain the full handling envelope.

High dust loading shortens H14 filter life.Maintain the G3/G4 prefilters and monitor resistance during production.

Available Options

Configure adjustable table, ventilated surface, induction barrier, exhaust connection and controls. Custom sizing can follow vessel and pallet routes.
