Product Introduction

This square low-profile FFU fits a 600 x 600 mm ceiling bay while keeping the cabinet depth to 318 mm. The published 2 x 2 ft configuration is deliberately limited to no more than 400 SCFM, making it the controlled-duty choice in this family rather than a high-output substitute for the longer models. Its smaller filter face and 35 lb unit weight support compact clean booths, inspection cells and constrained retrofit ceilings.

Key Features

Restricted-height installation

The 12.375 in cabinet height preserves overhead clearance where roof structure or services leave little room above the ceiling grid.

Compact airflow duty

A 315 CFM reference flow at 90 FPM suits small clean zones without applying the higher output of a larger filter face.

Square service footprint

Equal side dimensions simplify orientation around lights, sprinklers and access panels in a 2 x 2 ft bay.

Applications

Recommended for compact clean booths, small laboratory bays, localized inspection enclosures and shallow retrofit ceilings. The final operating point should be balanced with the selected filter, ceiling seal and return-air path while respecting the 400 SCFM limit of this size.

Solutions for Your Application

The ceiling void is too shallow for a conventional FFU cabinet.Use the 318 mm high chassis and reserve only the access clearance required above its compact 2 x 2 ft body.

A small module could be driven beyond its intended airflow range.Set the controller within the published limit and verify face velocity after the filter and ceiling seals are installed.

Available Options

Specify the final filter grade, electrical supply, speed-control interface, ceiling support and service direction to suit the installation. Airflow must remain within the supported duty of the 2 x 2 ft configuration.
