|
|
|
The
Commercial High Performance 10 & the Sanitation
Certified High Performance 7 Air Curtains are designed
to be an effective barrier against cold drafts in the winter
and hot air in the summer, flying insects and airborne
contaminants. |
|
|
|
To
achieve optimum protection, the air curtain should
be mounted on the inside of the building, flush to the
wall and as close to the top of the door opening as
possible. To ensure peak performance, keep the air
stream free of obstructions. |
|
|
|
The
air curtain will not perform properly if negative air
pressure exists in the building. Under these conditions,
a means for makeup air to the building must be provided
so that the air pressure on both sides of the opening is in
balance. |
|
|
|
Before
mounting the air curtain, check the supporting
structure to verify that it has sufficient load-carrying
capacity to support the weight of the air curtain(s).
The mounting hardware (supplied by others) should
be capable of supporting a minimum of three (3)
times the weight of the air curtain.
See Table 1 or Table 2. |

|
| A.
When determining the mounting location for the air |
|
|
curtain(s),
make sure that nothing interferes with the
curtain of air developed when the discharge vanes
are directed from 0° to 20° toward the door open-
ing. If the air stream strikes any obstruction (the
top edge of the doorway, a door opening device,
etc.), the effectiveness of the air curtain will be
greatly reduced. See Figure 2. |
|
| B.
For optimum performance, the bottom of the air |
|
|
curtain (discharge nozzle) should be no more than
1” above the top of the door opening with the air
curtain(s) mounted flush to the wall. If the air
curtain must be mounted higher, it must be
spaced out from the wall 3/8” for every inch
the air curtain is above the door opening. See
Figure 3. For optimum protection, any void
between the air curtain and the wall should be
sealed along the full length of the air curtain. |

dusty or greasy environments could require a
cleaning schedule of once every two months. If the
environment is not that dirty, the unit(s) should be
scheduled for cleaning a minimum of once every

Our
air curtains require very little servicing. All parts
are easily accessible for periodic inspection and
maintenance. Units should be cleaned at least twice
a year. Your particular application (the amount of dirt
and dust in the air) and location of the unit(s) will
determine how often your unit(s) will need to be
cleaned and serviced. All motors have permanently
lubricated, sealed, sleeve bearings and require no
maintenance |
|

Vacuum and scrape (if necessary) to remove |
|
|
|
the build-up of
dirt and debris. The motor(s)
are permanently lubricated and require no
additional lubrication. Re-install the cover
and intake grill. |
