Product Introduction

This 3400 x 3000 mm booth prioritizes process depth over the maximum width of the 4100 mm model. Its published airflow is approximately 11000 m³/h downflow with 1400 m³/h exhaust, using H14 final filters and rear-wall recirculation. The 3000 mm depth suits skids or large drums that need operator access around the front and sides.

Key Features

Deep equipment clearance

The three-metre depth accommodates skids and drum handling that project farther into the booth.

Recirculated clean downflow

Rear-wall return air passes through H14 filtration before re-entering the work zone.

Balanced partial exhaust

The 1400 m³/h exhaust draws replacement air inward at low level to support containment.

Applications

For deep powder-handling layouts with large drums or process skids. Maintain clear low-level induction and rear-return paths around the installed equipment.

Solutions for Your Application

A wide but shallow booth cannot contain a deep skid and operator access.Use the 3000 mm depth to bring the complete operation inside the protected zone.

Equipment blocks the rear-wall return grille.Reserve a service gap and validate return airflow with the skid installed.

Available Options

Select worktable, ventilated process surface, induction curtains or plates, and control monitoring. Width and depth can be customized to the skid.
