Product Introduction

The 680 x 835 x 550 mm BFU extends the cabinet along one axis while retaining the same depth and electrical basis as the square unit. Its added length provides a larger air-path and filter envelope for medium recirculation loops. SS41 and SUS304 housing options allow the enclosure material to be matched to the cleaning environment.

Key Features

Intermediate casing length

The 835 mm axis adds capacity without adopting the longest 985 mm family enclosure.

Equipment-side integration

The rectangular body follows medium tools and recirculation plenums more closely than a square cabinet.

Material selection

The casing is available in standard SS41 or cleanable SUS304 construction.

Applications

Designed for medium cleanroom recirculation loops, enclosed production equipment and filtered-air supply points where a square BFU has insufficient air-path area. Long-side support and service clearance should be provided.

Solutions for Your Application

The compact square casing restricts the available filter envelope.Use the 835 mm body to gain length while retaining a 680 mm width.

A full-length unit would occupy too much equipment roof space.Select this intermediate format when it meets the verified pressure and airflow duty.

Available Options

Specify SS41 or SUS304, final filter, blower operating point, inlet and outlet connections and access orientation. Verify the 60 Hz electrical basis before ordering.
