The cross-flow of a tangential fan, sometimes known as a tubular fan, was patented in 1893 by Paul Mortier and is used extensively in heating, ventilation, and air conditioning (HVAC), especially in ductless split air conditioners. The fan is usually long concerning the diameter, so the flow remains approximately two-dimensional away from the ends. The cross-flow fan uses an impeller with forward-curved blades, placed in a housing consisting of a rear wall and a vortex wall. Unlike radial machines, the main flow moves transversely across the impeller, passing the blading twice. What follows is a more detailed explanation of it and its functions. Below are some details about cross-flow fans and aluminum alloy cross flow fans.

時には管状ファンとして知られる接線ファンのクロスフローは、1893年にポール・モーティエによって特許を取得し、特にダクトレス分割エアコンで加熱、換気、エアコン（HVAC）で広く使用されています。ファンは通常、直径に関して長いので、流れは端から約2次元離れたままです。クロスフローファンは、後壁と渦の壁からなる住宅に配置された、順方向のブレードを備えたインペラーを使用します。ラジアルマシンとは異なり、メインフローはインペラーを横切って移動し、ブレードを2回通過させます。以下は、それとその機能のより詳細な説明です。以下は、クロスフローファンとアルミニウム合金のクロスフローファンに関するいくつかの詳細です。

Cross flow fan is also called as tangential blower fan, can be made with DC voltage such 12V and 24V or AC voltage such 100~240V cross flow fan, we have different sizes from smaller to bigger ones, for example, 30 series, 40 series and 60 series, the material of frame is metal and the material of impeller is aluminum alloy, color of frame is black, color of impeller is silver white, which are widely used in air conditioners and air purifiers, the characteristics is big air flow, high air pressure and easily fitted.
