STJH-ALUZINC-COATED-STEEL-FFU-1175X875

Fan Filter Unit 1175 × 875 mm Aluzinc-Coated Steel

A wider intermediate aluzinc FFU for process tools and clean bays needing more outlet area.

1175 x 875 x 280 mm housing
1170 x 870 x 69 mm filter
42 kg intermediate assembly

Введение продукции

The 1175 x 875 mm model expands the filter width to 870 mm and uses a slightly deeper 280 mm cabinet. At 42 kg, it provides a larger clean-air footprint than the 575 mm wide version without reaching the span or weight of the 1175 mm square unit. The aluminized-zinc steel housing and 0.35-0.50 m/s velocity range are retained for consistent family construction and balancing.

Основные характеристики

Expanded outlet width

The 870 mm filter face covers broader tools and inspection cells than the narrow family member.

Deeper intermediate plenum

The 280 mm housing distinguishes this size and accommodates airflow distribution across the wider face.

Consistent velocity envelope

The same 0.35-0.50 m/s range allows this model to be balanced within the accepted family duty.

Applications

Designed for broader process tools, inspection cells and intermediate ceiling modules where a 575 mm wide outlet is insufficient. The 42 kg load should be distributed along the perimeter, and fan duty should be set from the final system resistance.

Solutions for Your Application

The compact family size leaves uncovered width over the process.Select the 870 mm filter face to extend clean-air coverage without adopting the full square module.

The wider body imposes more load on the ceiling grid.Support the full rectangular perimeter and verify the frame for the listed 42 kg unit weight.

Доступные варианты

Confirm filter grade, power supply, speed control, gasket or seal and ceiling support. Surface finish and access direction can be adapted to the cleaning and service environment.
