Produkteinführung

This external control panel adds audible and visible filter alarms plus a reduced-speed night mode to basic FFU grouping. The 24 V control basis is intended for continuously operated cleanrooms that can reduce airflow during unoccupied periods but still need clear maintenance indication. It differs from the five-circuit panel through alarm and operating-mode functions.

Key Features

Maintenance indication

Two alarm channels provide both visual and audible notice of filter condition.

Unoccupied setback

Night mode reduces FFU duty without relying on manual fan-by-fan adjustment.

Accessible interface

External mounting keeps status and mode selection outside the clean space.
