弊社DCファンシリーズは、電気トルク機器におけるUSA技術の専門性とアジアの空力コンポーネントにおける経済的製造といった2つの世界の長所を取り入れています。その結果として、信頼性が高く購入しやすい製品が誕生しました。
Electric Torque Machines (ETM) of Arizona, USA社はダイレクトドライブアプリケーション向けに最適化された高性能連続トルクモータを設計および製造しています。ETM's F-series DC Motor SystemはHVLSファンアプリケーションにおいてその信頼性が知られている、唯一実績のある型式です。
The tapered, twisted & tilted design of the fan blade compensates for the substantial velocity differences that stretch from one end of the blade to the other. It ensures the blades produce the same amount of airflow across the entire length of the blade. (See below diagram).
Contrast this to the commonly found extruded blade designs of other makes where the blade contour is uniform along the length of the blade, the area directly beneath the center of the fan will have much lower air velocity. This causes an empty air ‘hole’ effect below the fan. (See below diagram)
Tapered & Twisted Blade Uniform Blade Design
Compensates for the substantial velocity differences that stretch from one end of the blade to the other. As a result, air flow is even throughout the entire area covered.
Uniform ContourBlade Design
When blade contour is uniform along the length of the blade as in the case of aluminum extrusion design, an area directly below the fan has no airflow being felt.
Fan Safety Features
FAN STABILIZATION WIRES
4 Guy wires are installed to keep the fan stable without excessive oscillation during operation.
