The opening for connecting the control switch is designed to accommodate a cabie with
a diameter of 1.6mm or 2.0mm only. (Therefore, a stranded cable cannot be connected.

Mitsubishi Air Curtains are the Perfect Way to Provide Your Premises with a
Comfortable, Clean and Hygienic Environment While Saving Energy
with a Quiet, Efficient and Powerful Operation

Patent and design registration pending for the following countries & areas:
CHINA, HONG KONG, GREAT BRITAIN, THAILAND, MALAYSIA, SINGAPORE, TAIWAN.
Design registration pending: U.S.A., ITALY.

TWIN NOZZLE

The twin nozzle design ensures that less extraneous air
enters the air curtain, while the outflow is wider.
Resistance to the influence of external airflow has been
strengthened, greatly improving insulation against heat
and cold.

COMPACT DESIGNEXTRAFAN RECTIFICATION PLATE

Compact and stylish it blends in readily with your
interior design.

By adjusting the
installation angle of
the main unit, the
airflow angle can be
altered both internally
and externally.

ExtraFan is a major improvement over the Line Flow
Fan. The fan is driven by an energy efficient motor and
costs even less to operate.

The use of Axial Fan(ExtraFan)makes it easier to
maintain the unit and keep the air curtain in top
condition at all times. Moreover, the
improvements that have resulted from the change to
the Axial Flow Fan from the Line Flow Fan mean that
fan life is now even longer.

The machine can be
installed vertically or
horizontally according
to the available space.

Ultra-Compact Slim Design

Adjustable Airflow Angle

New innovations in high-tech
hydromechanics have made
Mitsubishi Electric’s ExtraFan
run so quiet it may seem to
lack the strength of
conventional, noisier models.
Not so.
The ExtraFan not only
reduces noise it is also the
secret behind the GK-35’s
powerful, high-volume airflow.

Powerful airflow without the noise Ups speed while controlling direction

The rectification plate creates a highly directed, disc­shaped flow by transferring airflow from the propeller
fans without reduction to volume or velocity. The plate
forms the air into a smooth hemispherical wall,
producing a high-speed current in a single direction.

In a cold-storage facility without an air curtain, the inside temperature
increases from -5 to +4ºC in as little as two minutes, but if an air curtain is
used this time is extended to about 10 minutes, or approximately five times as
long. If the door is left open for five minutes, the temperature goes up to 10ºC if
no air curtain is used, as opposed to 2ºC when one is used. It was also
discovered that when an air curtain was used, 50% less energy was required
to reduce the inside temperature to -5ºC.

Not only does the installation of an
air curtain help to maintain a
constant comfortable indoor
temperature, it saves energy too.
Install an automatic door to achieve
even more economical operation and a
more pleasant indoor environment.

This night time test ascertained the effectiveness of Mitsubishi air curtains in
shutting out insects. A 40W mercury lamp was placed inside an air curtain
ejected from a 4cm-wide vent at a velocity of 8m/sec. The insect shut-out rate
was 70-80%.

*Insects such as flies which have high flying power may ingress into the room from the vicinity of the

floor face where wind velocity is comparatively low.

Economic benefits of installing an air curtain. (Savings are calculated using an appropriate heating load factor
required to keep room temperature constant at 28ºC for a room measuring 66.4m2 in area.)
