High-strength X-shaped tripod, high structural grip, stable motor center of gravity, fan operation without shaking.
The wheel disc is made of engineering plastic steel, which is rust-proof and safer.
The shaft core is equipped with an R-type pin to prevent the blades from falling off, and the safety level is further improved.
The 304 stainless steel/aluminum alloy sleeve tripod is used, which is rust-proof, acid-resistant, beautiful and durable. It can also prevent rainwater from flowing into the motor through the tripod.
The whole machine uses 304 stainless steel screws.
DC variable frequency motor, IP66 waterproof level, higher efficiency and more power saving.
The blades are made of engineering plastic steel, nylon 66+30% fiber, acid-resistant, no deformation, and good steel.
FRP fiberglass composite shell, hand-sprayed fiberglass, acid and alkali resistant, high temperature resistant.
