Produkteinführung

This 1175 x 1175 x 250 mm square fan filter unit provides the largest discharge area in the accepted aluzinc-steel family. Its 1170 x 1170 x 69 mm filter face and 52 kg unit weight distinguish it from the narrower rectangular models. It is intended for high-coverage ceiling bays and localized unidirectional-flow areas where one large square module can reduce the number of supply boundaries.

Key Features

Maximum family area

The square filter face offers the greatest clean-air discharge area among the three aluzinc configurations.

Broad-zone geometry

Equal 1175 mm sides suit large square ceiling bays and localized unidirectional-flow canopies.

Metallic plenum construction

The aluminized-zinc steel plate provides a consistent housing material across the size family.

Applications

Recommended for high-coverage cleanroom ceilings, large inspection zones and localized unidirectional-flow areas. The ceiling structure, lifting access and return-air capacity must be sized for the 52 kg module and broad filter face.

Solutions for Your Application

Multiple narrow FFUs create too many seams across a large square zone.Use the 1170 mm square filter face to consolidate supply coverage where the ceiling layout supports it.

A large module can overload a lightly framed grid.Provide full-perimeter structural support and verify the frame for the listed 52 kg equipment weight.

Verfügbare Optionen

Select the final filter, electrical package, speed control, ceiling seal and service clearance. Confirm lifting and support provisions before the large square module is ordered.
