Which Fan Delivers more air in the room ?
Your answer is here
Crompton Introduced new fan which covers 50% greater area in the room and industry leading air delivery with it's unique elevated & aerodynamically designed blade along with powerful motor
Premium Air 360 series fans come with gliding technology where in fan blades boast of aerodynamic design. This design is such that the wings of the fan is slightly ascended upwards which gives wider air coverage and improved air delivery. Crompton believes this way it increases the air coverage by 50%. Additionally, these premium fans come with anti-drag technology for smoother airflow, It is having powerful motor.
Ceiling Fan
A ceiling fan is a mechanical fan mounted on the ceiling of a room or space, usually electrically powered, suspended from the ceiling of a room, that uses hub-mounted rotating blades to circulate air. Ceiling fans typically rotate more slowly than other types of circulating fans, such as electric desk fans. They cool people effectively by introducing slow movement into the otherwise still, hot air of a room. Fans never actually cool air, unlike air-conditioning equipment, they in fact heat the air due to the waste heat from the motor and friction, but use significantly less power (cooling air is thermodynamically expensive). Conversely, a ceiling fan can also be used to reduce the stratification of warm air in a room by forcing it down to affect both occupants' sensations and thermostat readings, thereby improving climate control energy efficiency.
The key components of a ceiling fan are the following:
• An electric motor
• Blades (also known as paddles or wings) usually made from wood, plywood, iron, aluminium, MDF or plastic
• Blade irons (also known as blade brackets, blade arms, blade holders, or flanges), which hold the blades and connect them to the motor.
• Flywheel, a metal or plastic or tough rubber double-torus which is attached to the motor shaft, and to which the blade irons may be attached. The flywheel inner ring is locked to the shaft by a lock-screw, and the blade irons to the outer ring by bolts that feed into tapped metal inserts. Rubber or plastic flywheels may become brittle and break, a common cause of fan failure. Replacing the flywheel may require disconnecting wiring and requires removing the switch housing that's on the way for the flywheel to be removed and replaced.
• Rotor, alternative to blade irons. First patented by industrial designer Ron Rezek in 1991, the one-piece die cast rotor receives and secures the blades and bolts right to the motor, eliminating most balance problems and minimizing exposed fasteners.
• A mechanism for mounting the fan to the ceiling such as:
o Ball-and-socket system. With this system, there is a metal or plastic hemisphere mounted on the end of the downrod; this hemisphere rests in a ceiling-mounted metal bracket, or metal canopy, and allows the fan to move freely (which is very useful on vaulted ceilings). Some companies have come up with slight modifications of this design.
o J-hook (Claw hook) system. A type of mounting system where the ceiling fan hangs on a metal hook, attached to the ceiling. A rubber grommet is used to keep the fan in place and helps avoid vibration on the ceiling.
o U-bolt system. Similar to J-hook system, except that the hook on the ceiling is U-shaped and is being held by screws. One advantage of U-bolt system as opposed to J-hook system is that it wouldn't unscrew itself by the fan's torque in either direction. J-hook can be unscrewed by the fan torque when spinning clockwise (or counterclockwise if J-hook is left-hand threaded).
o Some fans can be mounted using a low-ceiling adapter, a special kit which must be purchased from the fan's manufacturer. This eliminates the need for a downrod, and is therefore useful in rooms with low ceiling clearance.
o In recent years, it has become increasingly common for a ball-and-socket fan to be designed such that the canopy (ceiling cover piece) can optionally be screwed directly into the top of the motor housing; then the whole fan can be secured directly onto the ceiling mounting bracket. This is known as a "close-to-ceiling" mount or flush mount.
Other components, which vary by model and style, can include:
• A downrod, a metal pipe used to suspend the fan from the ceiling. Downrods come in many lengths and widths, depending on the fan type.
• A decorative encasement for the motor (known as the "motor housing").
• A switch housing (also known as a "switch cup" or "nose column"), a metal or plastic cylinder mounted below and in the center of the fan's motor. The switch housing is used to conceal and protect various components, which can include wires, capacitors, and switches; on fans that require oiling, it often conceals the oil reservoir which lubricates the bearings. The switch housing also makes for a convenient place to mount a light kit.
• Blade badges, decorative adornments attached to the visible underside of the blades for the purpose of concealing the screws used to attach the blades to the blade irons.
• Assorted switches used for turning the fan on and off, adjusting the speed at which the blades rotate, changing the direction in which the blades rotate, and operating any lamps that may be present.
