Fan frame: The thick zinc coating (0.7mm thickness) ensures corrosion resistance; the bottomoutlet design makes fan structure more reasonable.
Belt pulley: The hub made of aviation aluminum alloy is light, tensile, high-strength and unlikelyto break. It is designed to serve many years without maintenance.
Fan blades: Six stainless steel blades (1.2mm thickness) which are formed in one step areAesthetic, durable and resistant to deformation, the blade passed the dynamic balance test andIts reasonable angle ensures maximum air flow and minimum noise. Blade width should be170mm
Shutter : High strength hot galvanized plate, the automatic opening-closing device makes itPossible to open and close louvers completely, maintain a 90-degree opening angle to ensureLouvers are windproof, rainproof and dust-proof.
Motor: Double support (E) belt drive, protection grade: IP55, insulation grade: F
Belt: Mitsubishi brand belt is long lasting, deformation free
