Maximum pressure reserve
The 400 Pa duty is selected for restrictive air paths rather than for maximum free-air volume.
STJH-HIGH-STATIC-PRESSURE-FFU-770-400PA
Fan Filter Unit 770 m³/h 400 Pa High-Static-Pressure
A low-flow, high-pressure FFU operating point for clean-air systems with substantial external resistance.
- 770 m³/h airflow duty
- Up to 400 Pa external pressure
- 1132 x 532 x 440 mm cabinet
Introducción del producto
This high-performance EC fan filter unit is configured around a 770 m³/h duty and the highest cited external differential pressure in the accepted series: 400 Pa. The 1132 x 532 x 440 mm cabinet is intended for systems where ductwork, prefiltration or dense terminal filtration creates more resistance than a standard ceiling FFU can overcome. The lower airflow point preserves pressure reserve, distinguishing it from the higher-volume models in the group.
Características clave
High-performance EC drive
An EC fan supports controllable operation as system resistance changes with filter loading.
Selectable final filtration
H14, U15 or U16 filter options allow the terminal stage to be matched to the clean-air requirement.

Applications
Intended for duct-connected cleanrooms, terminal systems with prefilters, high-grade final filters and ceiling networks with substantial pressure loss. The 770 m³/h point should be used where maintaining pressure reserve is more important than maximizing supply volume.
Solutions for Your Application
Opciones disponibles
Specify H14, U15 or U16 filtration, the duct or plenum connection, control interface and service orientation. Final fan speed must be set from measured system resistance rather than cabinet rating alone.
