2. PURPOSE OF THE DEVICE

The industrial air curtain is intended to be used in regions with a moderate and cold climate, in spaces where temperature

ranges from -15 to +40°C and of relative humidity up to 80% (at the temperature of +25°C), in conditions free from external

factors such as pollens, hydrometeor (horizontal precipitation) and chemical vapours.

In winters, air curtains protect against heat loss in rooms which is possible due to the airstream suitably directed that protects

the entrance of cold air into a heated space. In summers, the curtains may be used as cooling devices preventing the entry of

hot air from outside as well as air pollutants.

The ACR Pro industrial air curtains are designed to protect against heat losses in the gateways of buildings of medium and

high capacity especially such as the followings:

It is advisable to mount the device to the wall or the ceiling above the doorway on supporting mount pins or supporting

constructions ( shapes and dimensions of the supporting construction may be individually designed in compliance with durability

and strength requirements).

Pay special attention to proper leveling of the device. If the device is not placed in a horizontal or vertical position, it may result in dam-

aging the fan and consequently malfunctioning of the device. The air inlet and outlet must not be blocked by any objects. While install-

ing the unit, remember to provide easy access to the control panel. A few curtains of the same type may be installed in case of a bigger

doorway. They must be assembled side-by-side to make an uninterrupted stream of air. The curtain is mounted horizontally or vertically

To mount the curtain horizontally in a proper way, keep the dis-

tance of min. 300mm from the rear side of the device.

To mount the ACR Pro curtain to the ceiling, use the ACR Pro

multi-purpose connector. Mounting pins of diameter 11 may be

attached to the connector (not included in the delivery).

To mount the curtain vertically make sure the air outlet of the

curtain is as close as possible to the doorway and air gap is at

the height of the upper edge of the entry. Please, make sure to

keep the distance of about 300 mm between the outlet

casing and the wall.

To mount two ACR Pro curtains one above the other, it is neces-

sary to use the ACR Pro multi-purpose connector to install the

curtain to the wall.
