AIR CURTAINS
air curtains ENERGY
Our air curtains conserve energy and improve
comfort by limiting the escape of internal heat,
reducing cold drafts and providing a welcoming
down flow curtain of warm air at entrance ways in
industrial plants and store buildings. The resulting
mixture of warmed air disperses gently in all
directions at floor level to give uniform temperature
over a wide area from floor to ceiling with only a
few degrees difference.
CONVENIENCE
Our air curtains allow personnel and cargo to pass
freely from one area to another while maintaining
desired temperatures.
An added safety feature is the free flow of traffic
with an unobstructed view through the opening,
eliminating doorway accidents.
TYPICAL USES
Easily mounted over entrance ways of warehouse doors
up to 16 feet high, the air curtains direct an invisible stream
of stratified heated air downward. In addition to adding to
employee and customer comfort during cold weather they
provide important energy savings in three ways:
2. The high velocity curtain of air deflects winds
and reduces excessive heat loss through open
doorways.
3. During warm weather they can direct a stream
of air downward to help keep dust, dirt, insects
and fumes from entering through open doorways.
If air conditioning exists in the building during warm
weather, the air curtains can be used to prevent
loss of conditioned air as well.
1. In cold weather they reduce the load on heating systems.
By drawing warm air down to floor level where it is needed,
our air curtains utilize the 50% of wasted heated air trapped
under ceilings. Stratified air is mixed and circulated with
building heat and heat given off by lights and machinery, etc.

Our air curtains create an invisible barrier of high
velocity air to stop cold or warm air infiltrating plant
facilities and work areas.
Stop entry of cold or warm air when doors are
    open.
Prevent the possibility of accidents with unobstructed
   view of passageways.
IMPORTANT: MUST BE INSTALLED ON WARM
SIDE OF DOORWAY OPENING WHEN USED FOR
TEMPERATURE CONTROL
Eliminate need for expensive plastic stripping, flapper
   doors, or canvas curtains.
Cold weather can be further deterred at door opening if
space heater in plant is directed toward intake of the air
curtain.

SPECIFICATIONS AND FEATURES
FOR ARCHITECTS AND ENGINEERS EASY INSTALLATION
Our air curtains shall have a self-contained one piece
housing, fire retardant and corrosion proof, in-
corporated with a double extended shaft motor, direct
drive double width and double inlet squirrel cage blower
wheels and fan housings.
Our air curtains are bolted to wall with four fasteners
and connected to electric power source.
AIR VELOCITY CONTROL FOR VARIABLE
AIR SPEED
Adjustable louver damper controls are provided in
order to adjust rate of air flow.
Shall have wedge shaped discharge nozzle containing
adjustable air deflectors with 40% sweep front to back.
When used over a doorway to retain warm or cold
temperature, proper velocity adjustment is imperative
for maximum efficiency. Velocity Control can reduce
air velocity up to 60% with louvers in totally closed
position.
Housing shall be sufficient strength for fastening to wall
on both ends without any intermediate support.
HEAVY DUTY ELECTRIC MOTOR
Continuous duty type motor with double sealed lifetime
pre-lubricated stainless steel ball bearings, resilient
mounted and protected by an automatic thermal overload
switch. Underwriters Laboratories Listed and Canadian
Standards Association Certified. Explosion proof motors
available.
AIR DIRECTIONAL CONTROL
Adjustable
vanes at outlet
nozzle for
directing air
to compensate
for possible
draft conditions
through
doorways.
air curtains
FIRE RETARDANT AND CORROSION PROOF
Steel models are of 18 gauge paintlock metal and double
protected with gray, baked, rust preventative electrostatic
polyurethane powder coating.
NOISE LEVEL
Our air curtains operate under a low noise level in the
interest and comfort of personnel working in the immediate
vicinity.
