FFU et équipement de purification de l'air terminal
Unité de filtre à ventilateur à haut débit d'air
A large-format FFU with two matched EC blowers and a broad final-filter face for supplying substantially more clean air from a single reinforced ceiling module.
- Twin Matched EC Blowers
- Large 1200 mm Module Format
- Broad Active Filter Area
- Balanced Dual-Inlet Plenum
Introduction de produit
The high-airflow fan filter unit expands both the filter face and fan capacity. Two matched EC blowers feed separate zones of a common reinforced plenum, while a central controller maintains coordinated speed. The large active filter area distributes the combined flow across a broad ceiling footprint and reduces the number of individual modules needed above a high-demand work zone. Internal splitters and a full-width diffuser prevent the two fan streams from producing a visible centerline or opposing jets.
Key Features
A divided inlet plenum equalizes the two fan streams before they reach the common final-filter face.
The 1200 mm square housing covers a large ceiling area while using one power and control connection.
A reinforced perimeter and intermediate cross-member support the wide filter and diffuser against bowing.
Préoccupations du client produit
High airflow from one ceiling bay must remain uniform across a large face without overloading a single motor or distorting the filter frame.
Several small FFUs require many power drops, controllers and ceiling penetrations over one work zone.A large dual-blower module consolidates airflow, power and control into one reinforced ceiling footprint.
A single central blower creates excessive velocity beneath the hub and weak flow at the far corners.Twin fans, a divided inlet and broad distribution chamber spread the flow before the common filter face.
A wide unsupported final filter can bow, unseat its gasket or touch the downstream diffuser.Intermediate structural support and a rigid perimeter frame maintain filter compression across the full span.
Mismatched fan speeds create an uneven outlet pattern and unnecessary turbulence along the module centerline.The common EC controller synchronizes both blowers and allows the two sections to be balanced as one unit.
