STjh compact 650 mm high cleanroom recirculation unit with shallow EC fan and H14 filter plenum

STJH-CLEANROOM-RCU-650H-1000

Cleanroom Recirculation Air Unit 650 mm Compact

A low-height recirculation unit retaining 1000 m³/h nominal duty for shallow technical ceilings.

650 mm compact height
1000 m³/h nominal airflow
2050 m³/h maximum airflow

Introduction de produit

The compact RCU reduces total height to 650 mm while retaining the same 1200 x 1200 mm grid format and 1000 m³/h nominal duty. Its published maximum airflow reaches 2050 m³/h, providing additional balancing range for retrofit cleanrooms. The shorter housing is the priority where ceiling depth is constrained and a separate local cooling configuration is not the defining requirement.

Key Features

Reduced plenum demand

The 650 mm enclosure saves 160 mm of height compared with the taller hygienic model.

Wide airflow headroom

A 2050 m³/h maximum supports recovery or higher operating duty above the nominal point.

Broad square grid

The 1200 x 1200 mm format distributes recirculated air across a large ceiling zone.

Applications

Suitable for retrofit cleanrooms and shallow technical ceilings that require local recirculation over a broad grid bay. The selected airflow should reflect room leakage, return capacity and allowable sound.

Solutions for Your Application

The available plenum cannot accept the 810 mm hygienic housing.Use the 650 mm compact model while retaining the 1000 m³/h nominal recirculation point.

The room may need short-term airflow above nominal duty.Commission within the published range up to 2050 m³/h after verifying system resistance.

Options disponibles

Confirm filter configuration, EC control, service access, grid support and any thermal section. Final settings must be established from room performance.
