Fan
Facts
Many
Fans Move Very Little Air
A ceiling fan that looks nice but moves little air is a comfort to
no one. One of the keys to proper air movement is blade pitch. The
greater the pitch—the angle of the blade—the greater the
air movement providing the blade pitch has been properly harmonized
with the motor. But some manufacturers skimp on materials and don’t
use large enough or powerful enough motors to support proper blade
pitch. So they compromise on blade pitch, sacrificing proper air movement
to reduce the stress on undersized or under-powered motors. Many fans
also use extra thin blades to reduce cost. The reduced blade surface
area means reduced air movement.
Why Many Fans Are Less Efficient
The amount of energy a fan consumes plus the volume of air the fan
moves determines the fan’s overall efficiency. Small, low wattage
motors may use little energy, but they also move very little air,
resulting in very inefficient fans.
Why
Many Fans Are Noisy
An electrical humming created when a ceiling fan is running is usually
the result of poor engineering design and a lack of precision manufacturing.
Some manufacturers use generic, inexpensive ball bearings to reduce
cost, even though these are a common source of operating noise. A
lack of proper dampening between metal parts can also create and intensify
noise, as can the use of extra thin sheet metal motor and mounting
system parts.
Why Many Fans Wobble
Many factors can produce fan wobble. Substandard blade materials
and improper blade sealing can produce blades that absorb moisture
and warp—a prime source of wobble. Blades that are not matched
in carefully weighed and balanced sets can also wobble. Inconsistent
blade mounting brackets can create varying degrees of pitch (blade
angle), throwing a fan into an unbalanced wobble. And poorly manufactured
motors have rotors that can easily get out of balance, generating
wobble from the very heart of the fan. Inexpensive mounting systems
with pin fasteners can also contribute to wobble.
Common
Reasons Substandard Fans Break Down Prematurely
- Motor size and blade pitch are not specified and matched correctly.
- Improperly installed on/off pull chains can become faulty and be
pulled out of the housing.
- Inadequate quality, testing, manufacturing and inspection procedures
send poor quality fans to market.
- Defective motor windings can lead to electrical shorts in the motor.
- Low quality fan bearings may be “shielded” on one side
only, allowing dust to enter and cause premature failure.
- Inexpensive materials, poor engineering, and substandard manufacturing
processes are used to create “bargain” fans.
- Poor Packing and storage
Why Brass Finishes Are Not Alike
In the beginning all brass finishes look great. Then tarnish and
dark spots begin to appear. You may even notice the brass on the fan
is a different color than the light kit you just added!
Quality brass and other metallic finishes include a series of grinding
and buffing steps between multiple plating processes. To help determine
the quality of a plated finish, look at the surface closely for scratches
or unevenness of finish. Does the surface spot easily? If so, avoid
the fan. Can you feel a smooth protective coating? That’s a
sign of the kind of quality you’ll find in the famous Hunter
Bright Brass Finish®.
Why a Hunter Warranty
Makes a Difference
Hunter backs its fans with a lifetime limited motor warranty, and
backs that warranty with nearly 120 years in the ceiling fan business.
No other manufacturer has that kind of record to stand on. So you
get the peace of mind of knowing you’ve got the best-backed
warranty in the business!
A
Common Mistake
Many people fit fans as an afterthought. By there very nature ceiling
fans must located in conspicuous areas to work effectively. Often
a fan is the most central piece of furniture in a room and the most
obvious. With this in mind a fan should be carefully chosen and attractive
to look at. Unfortunately this aspect is often overlooked.
Choose
Quality, Choose Hunter!
