The 54-inch seven-blade DC negative pressure fan is an efficient, energy-saving and durable ventilation equipment. It uses a DC variable frequency motor and IP66 waterproof rating, which is more efficient and energy-saving. It is suitable for various places, including greenhouses, livestock farms and factories. It can effectively discharge exhaust gas, keep the air fresh and improve the working environment. Contact us now to learn more.
High-strength X-shaped footrest, high structural grip, stable motor center of gravity, and no shaking when the fan runs.
The wheel 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 footrest is used, which is rust-proof, acid-resistant, alkali-resistant, beautiful and durable. And it can 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, more energy saving.
The blades are made of engineering plastic steel, nylon 66+30% fiber, acid and alkali resistant, no deformation, good steel.
FRP glass fiber composite shell, hand-sprayed glass fiber, acid and alkali resistant, high temperature resistant.
