Introducción del producto

At 680 x 985 x 550 mm, this published BFU casing has the longest footprint in the three-size group. The extended cabinet supports broader equipment integration and a larger filter path while retaining the sirocco blower, 220 V single-phase 60 Hz supply and SS41 or SUS304 material choices. It is selected for area and layout, not as a label-only variant of the smaller units.

Características clave

Maximum family length

The 985 mm axis provides the greatest casing area for broad clean-air equipment integration.

Stable cabinet depth

The 550 mm depth remains consistent while plan dimensions grow for a longer filter path.

Duct-ready centrifugal fan

The sirocco blower supports connected recirculation arrangements where external resistance must be considered.

Applications

Suitable for broad clean-air zones, large equipment roofs and recirculation loops needing more casing area than the 680 x 835 mm model. Structure and lifting access should suit the long enclosure.

Solutions for Your Application

A medium BFU leaves part of a broad process enclosure without direct coverage.Use the 985 mm casing where its longer filter path aligns with the equipment footprint.

The extended cabinet is harder to support from isolated points.Provide distributed mounting and retain service access along the full length.

Opciones disponibles

Coordinate material, filter grade, fan duty, duct interface and mounting points with the equipment design. Confirm voltage and frequency compatibility.
