STjh large 1132 mm square balanced-performance FFU with dual EC fan inlets and full filter face

STJH-HIGH-STATIC-PRESSURE-FFU-1555-320PA

Fan Filter Unit 1555 m³/h 320 Pa High-Static-Pressure

A large square FFU for broad clean-air coverage with a 1555 m³/h, 320 Pa balanced duty.

1132 x 1132 mm square footprint
1555 m³/h airflow
320 Pa external pressure capability

مقدمة المنتج

This 1132 x 1132 mm balanced-performance module provides the largest filter footprint and airflow of the three accepted high-pressure models. At a 0.3 m/s face velocity it delivers 1555 m³/h while retaining 320 Pa of available external differential pressure. The square geometry is intended for broad ceiling bays where one module must cover more area but still overcome meaningful system resistance.

الخصائص الرئيسية

Large-area supply

The square 1132 mm footprint distributes filtered air across a wider ceiling zone than the narrow high-performance cabinets.

Documented face velocity

The 0.3 m/s operating point links the large filter face to a defined 1555 m³/h supply duty.

Useful pressure reserve

A 320 Pa external capability supports connected resistance while prioritizing higher air volume.

Applications

Designed for large cleanroom ceiling bays, broad process tools and localized unidirectional-flow zones that need more coverage per unit. The supporting grid, lifting route and return-air path must be sized for the larger footprint and 1555 m³/h supply volume.

Solutions for Your Application

Narrow high-pressure FFUs would require too many modules across a broad bay.Use the 1132 mm square face to consolidate coverage while retaining 320 Pa of available pressure.

A large airflow module could overwhelm an undersized return path.Confirm the room return capacity and commission the EC fan at the documented 0.3 m/s reference point or the verified project duty.

الخيارات المتاحة

Specify the high-efficiency filter, control interface, sealing system and service arrangement. Structural and airflow coordination should reflect the full 1132 mm square footprint.
