FFU Group Control Panel Filter Alarm and Night Mode

A grouped FFU panel adding filter alarms and reduced-duty night operation.

Audible and visible filter alarm
Reduced-speed night mode
External 24 V controls

商品紹介

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.

主要な特徴

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.

Filter condition is missed until airflow visibly declines.Use audible and visible alarm outputs to prompt inspection.

Fans remain at daytime duty through empty periods.Apply reduced-speed night mode within the room's validated operating limits.

利用可能なオプション

Define FFU group size, alarm reset, night speed, schedule interface and enclosure location. Confirm pressure retention at the reduced setting.
