-Message from the representative of KDK
Group
KDK has been going through the history with
Electric Fan. In 1913 KDK started to produce
Electric Fan. It was the first alternate E-fan
in Japan. In 1918 KDK E-Fans were exported to
Asia, South America, Southern Ocean, Australia,
and became the most famous top brand.
Today, the main product is Ventilating Fan.
Range Hood, Air Curtain, Hand Dryer, Ceiling
Fan, Dehumidifier and Air Moving Equipment are
also provided.
KDK has grown up over long period of time in
overseas market. In November 2004, “KDK” has
been in business for 95years. KDK group
continues to strengthen the relationship with
community and provide high quality products for
your comfortable life. |
Why are KDK fan so quiet?
KDK fan are quiet for a number of reasons, including:
Tip Speed KDK fan use a wide blower wheel that moves a
large amount of air at reduced RPMs. The larger wheel plus lower RPMs, amounts
to less tip speed and noise. Double Suction Blower Wheel The blower wheel
draws in air from both sides, so there's more area for the air to enter the
wheel. This cuts down on noise and makes the ventilation process more efficient.
Exhaust Outlet The outlet on the discharge side of KDK fan is as wide as
the blower wheel, allowing less turbulent airflow as it enters the duct. Quiet
Motor KDK fan feature four pole condenser motors, which are an advanced version
of a Permanent Split Capacitor (PSC) motor. The four pole design helps the fan
rotate smoothly and evenly, making KDK motors among the most efficient fan
motors around.What makes KDK fan so
energy efficient?
In terms of input wattage, KDK fan are among the lowest in the industry. This
low wattage draw is accomplished in a number of ways, including:
Unique Motor Design The fan condenser acts like a capacitor to store electrical
energy and deliver it quickly and in exact amounts to the coil. This reduces the
power draw, thus improving the electrical efficiency of the motor. Selective
Application KDK builds its own fan motors and components, therefore optimizing
efficiency by matching the exact motor characteristics with the desired
performance of the fans. Wide Blower Wheel The wide blower wheel improves
airflow efficiency, enabling the fan to operate at a lower RPM and reduce energy
usage.
Why do KDK fan have such a long life?
KDK fan are designed to provide continuous operation for a minimum of 30,000
hours. They are actually designed to provide up to 100,000 hours of operation,
but most fan haven't been around long enough to reach that goal in testing. Some
fan however, have reached 60,000 hours of testing with virtually no wear on
their components.
