FFU ومعدات تنقية الهواء الطرفية
FFU لوحة التحكم المجموعة
A compact wall panel that gives one cleanroom zone coordinated start, stop, speed presets and fault indication without requiring a full central-control cabinet.
- Dedicated Zone Operation
- Group Speed Presets
- Local Fault Indication
- Compact Wall Enclosure
مقدمة المنتج
The FFU group control panel operates a defined group of EC fan filter units serving one room or process zone. A small touchscreen or selector interface provides common start/stop and preset airflow levels, while addressable communication or isolated analogue outputs deliver commands to the connected fans. Status lamps and a summary alarm relay show whether the group is available without exposing the complexity of a facility-wide supervisory system. The panel can work independently or report its group state upward to a central controller.
الخصائص الرئيسية
Preset production, standby and boost modes reduce repeated manual adjustment.
A local summary alarm identifies communication or fan failure within the controlled group.
Compact low-voltage construction suits wall mounting near the served cleanroom.
مخاوف المنتج للعملاء
A small FFU zone needs coordinated operation and fault visibility, but a large central cabinet can be disproportionate to the number of connected units.
Individual wall switches leave adjacent FFUs running at mismatched speeds.A shared group setpoint sends the same operating command to every fan in the zone.
Operators cannot tell whether a stopped unit is disabled or has a communication fault.Separate run and alarm indications distinguish normal standby from abnormal loss of feedback.
A small room cannot justify the space and wiring of a full supervisory cabinet.The compact wall enclosure combines low-voltage control, group display and field terminals.
Future central monitoring would require replacing the original local controls.An optional network port allows the group panel to become a subordinate zone node.
