STjh 1175 x 575 mm aluzinc FFU with a long narrow casing, central wire-guarded intake and two carrying handles

STJH-ALUZINC-COATED-STEEL-FFU-1175X575

Fan Filter Unit 1175 × 575 mm Aluzinc-Coated Steel

A narrow 1175 x 575 mm aluzinc-steel FFU for standard cleanroom ceiling bays and compact cells.

1175 x 575 x 250 mm housing
1170 x 570 x 69 mm filter
0.35-0.50 m/s face-velocity range

Introdução do produto

This model uses an aluminized-zinc steel cabinet measuring 1175 x 575 x 250 mm around a 1170 x 570 x 69 mm final filter. The narrow rectangular face is the most compact discharge area in its three-size family, making it suitable for standard ceiling bays and localized production cells. A published 0.35-0.50 m/s velocity range and no more than 50 dBA noise provide the operating envelope for balancing.

Características-chave

Narrow ceiling footprint

The 575 mm width fits compact bays while the 1175 mm length follows common long-grid geometry.

Aluzinc cabinet construction

Aluminized-zinc steel provides a practical metallic housing for plenum-side cleanroom service.

Defined acoustic limit

The cited sound level of no more than 50 dBA supports selection for occupied production areas.

Applications

Suitable for standard cleanroom ceiling bays, compact process tools and localized production cells using a narrow rectangular supply footprint. The velocity should be set only after the filter, ceiling seal and return-air route are installed.

Solutions for Your Application

A wider FFU conflicts with adjacent ceiling services.Use the 575 mm wide housing to preserve space for lighting, sprinklers or access panels along the bay.

Uncontrolled fan output could disturb a sensitive workstation.Balance within the documented 0.35-0.50 m/s face-velocity range and verify room-side uniformity.

Opções disponíveis

Specify the final filter, speed-control arrangement, ceiling seal and aluzinc finish. Confirm compatibility with the 220 V, 50 Hz electrical basis or request a project-specific configuration.
