| FJDHH-1530 Heavy hammer-type |
1530*1530*400mm | outer frame material | 80g galvanized sheet | 1,It adopts CNC equipment automatic processing technology, one-time molding, with thick galvanized layer (80g/m2) and strong corrosion resistance, and is equipped with drain holes at the bottom. 2,The aviation aluminum alloy V-shaped wheel hub is hot-pressed and casted, with light material, high strength, good toughness, anti-breaking, and special bearings. 3,The six new laser-cut stainless steel blades are stamped at a time, with no deformation, no cracking, beautiful appearance and durability. 4, Heavy hammer-type opening and closing mechanism is adopted. The opening and closing mechanism uses a heavy hammer mechanism to make the shutter achieve windproof, dustproof and rainproof function. 5,Strict quality testing procedures: noise testing, vibration testing, rotational concentricity performance testing, blade speed testing, dynamic balance testing, air volume testing, and overall efficiency testing. |
