Huge hvls fan for restaurant

 

When it comes to restaurants, “comfort” is more than just a food category – it’s vital to creating a welcoming atmosphere. Most restaurants maintain their thermostats at a temperature pleasing to the vast majority of people – typically 68°F to 72°.

However, maintaining that ideal temperature is harder than it sounds. While the thermostat may be set at 70°F, the air near a busy kitchen might be closer to 80°F. Guests under an air conditioning vent may feel closer to 55°F or 60°F. Large windows, indoor-outdoor seating, constantly opening doors, hot plates of food and more can hamper temperature uniformity in a dining area.

Ceiling fans are a simple, effective solution. Most people think of fans solely as a cooling instrument, but overhead fans are also the most effective way to distribute both air-conditioned and heated air. Using fans to mix the air creates consistent temperatures throughout the restaurant, eliminating troublesome hot and cold spots.

In the world of personal comfort, which is typically managed through energy-intensive heating, ventilation and air-conditioning systems, ceiling fans are also an energy-efficient, environmentally friendly choice.

10+ SAFETY GUARANTEE


DAWANG

STREAMLINED VARIABLE CROSS-SECTION

Conform to aerodynamic equal chord length theory,combined with the relative linear velocity principle,the blade narrows and thins from root to tip till tail then widen,the air is more even and uniform.

DAWANG

AVIATION ALUMINUM PLATE

1.5mm thickness 5052 Ultra-high toughness aviation aluminum plate can load more than 3Ton tensile to ensure the blade can deform quickly and absorb external force effectively, It can prevent the blade from breaking,avoid the damage to the motor and other structural parts reatly.

DAWANG

BLADE HIGH-STRENGTH CONNECTION

Each blade is fixed with the buffer cavity by 16pcs high-strength rivets, each rivet can load 1.5 ton shear force.

DAWANG

BUFFER DEVICE

The blade and petiole flexible connects with buffer device, the rubber absorbs the most vibration from blades when running.

DAWANG

ANTI-FALLING RING

The concave flange are engaged with the convex anti-falling ring each other under the gravity to ensure a reliable connection between the flange and motor.

DAWANG

SAFETY RING

Connect the 5 petioles into a whole to form the sleeve with the frame lower hub to prevent the petioles from falling.

DAWANG

MORTISE AND TENON PETIOLE CONNECTION

The convex petiole with concave buffer device form the Joint engaged,eliminate the centrifugal force from the blades when the fan is running and the shear force when the fan starts and stops.

DAWANG

HIGH-TENSILE STRENGTH PETIOLE

6061-T6 petiole,high strenght,HB90 hardness,it has good corrosion resistance with 205MPa tensile strength.

Blades- Airflow components

1.Blade design-Streamline variable cross-section
Conform to aerodynamic equal chord length theory,combined with the relative linear velocity principle,the blade narrows(304-186mm) and thins(43mm-21mm) from root to tip till tail then widen,the air is more even and uniform.
2.Blade material-Aviation aluminum alloy
1.5mm thickness No.5052H32 aviation aluminum alloy original plate,precision CNC molding,high strength and flexibility ensure the blade not to be broken.
3.Blade weight-More lighter and safer
6.7kg per blade(24ft),less blades,lighter weight,it can reduces the motor load,prolong the life,more safe and cost-efficient.

Connection:Patented full mortise and tenon structural design to ensure the whole fan safety:

1.Blade and petiole
Mortise and tenon connection:
The convex petiole with concave buffer device form the Joint engaged,eliminate the centrifugal force from the blades when the fan is running and the shear force when the fan starts and stops.
The transverse screw is the same direction with fan running track to avoiding the shear in order to ensure the blade will not broken,eliminate the possible Safety hazards radically.
2.Petiole and wheel hub
The petiole and hub/motor are integrated by the stepped concave-convex sections to engage each other.The overall structure is used to withstand the centrifugal force during running,and all fasteners are not stressed.
3.Motor and flange roulette
Safety ring:Connect the 5 petioles and motor upper cover form the whole,adopt the occlusion structural to even the force of the whole fan.
Anti-falling roulette:The concave flange roulette engaged with the convex anti-falling ring each other under the gravity to ensure the reliable connection between the flange roulette and motor.
