Ventilateur circulaire à conduit en ligne
A compact mixed-flow fan for round branch ducts, combining an EC motor, smooth polymer casing and quick-release service section in a straight-through package.
- Compact Round-Duct Installation
- Energy-Efficient EC Motor
- Quick-Release Service Section
- Flexible Mounting Orientation
Introduction de produit
The circular inline duct fan integrates a mixed-flow impeller and electronically commutated motor inside a smooth molded housing sized for standard spiral duct. Round inlet and outlet spigots preserve a straight air path, while the center fan section can be released from its mounting clips for cleaning or replacement without dismantling the surrounding duct. Its compact body is suited to cleanroom support rooms and ventilation branches where space, sound and simple service access are important.
Key Features
An EC motor accepts variable-speed control and maintains good efficiency at reduced airflow settings.
Tool-light mounting clips allow the central motor and impeller section to separate from the fixed duct spigots.
The balanced motor-impeller assembly can operate horizontally, vertically or at an intermediate installation angle.
Préoccupations du client produit
Small circular branches often lack room for a conventional fan cabinet and are difficult to dismantle when the impeller requires cleaning.
A bulky rectangular fan forces extra transitions and consumes limited ceiling-void space.Round spigot connections and a short cylindrical body fit directly between standard circular duct sections.
Removing a fixed inline fan requires cutting or disassembling the connected duct.Quick-release clamps detach the service section while the inlet and outlet collars remain mounted.
A single-speed motor wastes energy when the room is unoccupied or the branch damper is partly closed.The EC motor can reduce speed from a local controller or building-management signal to match the required airflow.
Vibration from a small high-speed fan becomes audible through lightweight spiral duct.A balanced mixed-flow wheel, resilient mounting feet and optional flexible couplings limit structure-borne noise.
