Air door / Air curtain / Fly fan
Air curtain
stops outside drafts, flying insects and airborne pollutants from entering your
operation. The door plunger switch activates the air curtain when the door is
opened and shuts it off when the door is closed to help conserve energy. The most common use is a downward facing blower fan mounted over
an entrance to a building, or an opening between two spaces conditioned at different
temperatures. High Performance Air
curtains save energy by minimizing heated and air conditioned air loss through
open doorways.

Why You Need an Air Curtain ?
Air Curtains some times called Air door create a seamless barrier of air over any door, window, or
opening allowing ease of accessibility into and out of the building. Air
Curtains are a huge energy savings device as they help to maintain interior
building temperatures while doors and windows are constantly being opened and
closed. By maintaining comfortable indoor temperatures, employee
productivity increases and energy costs decrease. They also prevent dirt, dust,
and fumes from entering and deter flying insects providing a cleaner, more
sanitary environment. Specified to fit your unique application and available
with a large variety of size, color, and control options. Air first enters the
air door cabinet through the air intake (often called grill) and thereafter is
spiraled out at a higher velocity by the circulating fans. Although all air
doors function by similar principal, air doors have been designed to suit
specific applications including temperature control, sanitation and wind
blocking.
Air doors,
also commonly called air curtains, are used in many commercial and industrial
applications. They mount over your existing door opening and operate to protect
your inside environment from insects, dust, dirt and just about any airborne
pollutant. Our highly uniform air stream reduces unwanted/unconditioned air
infiltration while enabling doorways to be left open so that people, equipment
and inventory can pass freely. There are no gaps in our air flow!
In the summer months air curtains keep hot, humid air and bugs outside
where they belong, while maintaining a cool, comfortable environment inside. In
the winter air curtains recirculate the hot air that naturally rises to
the ceiling, keeping the exterior cold drafts from entering through open
doorways and prevent heated air from escaping.
How an air curtain / Air door
work ?
Once the power is on, air is brought into the unit through the
intake, enters the fan housing and is accelerated by the fan. This fast moving
air goes into a plenum, which allows for an even distribution of air along the
full length of the discharge nozzle. Aerofoil shaped vanes in the nozzle
create a uniform air stream with minimal turbulence.
·
For efficient air curtain performance, the angle of the
discharge nozzle must be set correctly. An air curtain nozzle should be adjustable
to aim inward or outward up to 20 degrees from the opening.The air discharged
through the nozzle creates a jet stream to the floor. Approximately 80% of the
air returns to the intake side of the air curtain, and 20% goes in the opposite
direction.Non-recirculating air curtains can be mounted horizontally above the
door or vertically on one or both sides of the door, depending on the space
available and the height, width and physical characteristics of the opening.
Horizontal mounting above the door minimizes the chances of damaging the air
curtain. Protective measures should be taken if the air curtain is mounted
vertically.Seals in air conditioning and seals out hot, humid air to maintain a
controlled environment. This is a perfect application for retail and restaurant
establishments that wish to keep their customers comfortable while shopping or
eating.
·
Repels insects, prevents microorganisms from entering building
and helps to maintain hygienic standards. This application will keep help keep
the bugs out whether you are in an industrial setting or a retail / restaurant
establishment.
·
Enhances customer and employee comfort by recirculating interior
air for a balanced temperature.
·
Prevents the infiltration of dust, dirt and objectionable fumes
from contaminating sanitary environments. This is a perfect application
for an overhead door in an industrial setting.
·
Maintains positive pressure in clean room environments and
eliminates the need for airlocks.
There are two major types of air curtains:
Non recirculating Air Curtains
Non recirculating air curtains are more widely used than the
recirculating type because they are easier and less costly to install and have
lower maintenance costs.
Recirculating Air Curtains
Recirculating air curtains are mainly used in places with
constant foot traffic such as supermarkets and store entrances.
recirculating air curtains are called Air Entrance Systems, as they are
built into the entrance, usually when the entrance is being constructed. They
emit air from a discharge grille on one side of the door opening, collect it
through a receiving grille on the opposite side and return it through duct work
to the discharge grille. The non obtrusive wide stream of low velocity air
created by recirculating air curtains is more desirable for separating
environments.
Air Curtain maintenance
Our air curtains require minimal maintenance. Scheduled
cleaning, at least once every three months, will ensure the air curtain works
properly and extends the life cycle of the product. Extremely dirty, dusty or
greasy environments could require a more aggressive cleaning schedule.
Cleaning Air curtain
Switch the power off at the service panel and lock the service
panel to prevent power from being switched on accidentally. Remove the air
intake grille for access to the blower housing and motor(s). Remove the bottom
access panel on heated models for access to the blower housings and motor(s).
Vacuum and scrape (if necessary) to remove the built up dirt and debris. For
instructions for your particular model, consult the appropriate installation
instructions.
