Sonniger Guard Commercial Air Curtain (LPHW, electric or ambient air)
GUARD is a professional and attractive air curtain, whose main objective is to maintain a protective barrier at the entrance to the building.
The air curtain is intended to be used in regions with a moderate and cold climate, in spaces where the temperature ranges from -10 to +40°C, and in conditions free from external factors such as pollens and hydrometeor (horizontal precipitation).
In winter, air curtains protect against heat loss in rooms by directing an airstream across the entranceway and preventing cold air from entering the heated space.. In summer, the curtains may be used as cooling devices preventing the entry of hot air and
pollutants from outside.
The GUARD air curtains are designed to protect against heat losses in buildings of medium and high capacity and with a required
mounting height is of 4 m such as:
- supermarkets, large retail spaces,
- car showrooms and service stations,
- sports and show halls,
- exhibition surfaces
GUARD air curtains have an efficient ventilator combined with a built-in three-step motor along with two-row coils that give an optimized range of parameters.
It is important to underline that the air curtains' electric range is equipped in a new generation of self-regulating PTC heaters.
High-performance parameters – air output 4800 m³/h, air throw up to 4 m.
Horizontal installation under the ceiling using mounting pins
Installation under the ceiling is done by using 4 M8 pins. In order to hang the device on the pins, drill holes Ø 8-9mm in the EPP housing directly in front of the existing holes in the steel inlet grille. The exact location is indicated by special tags on the EPP housing. The pins should be screwed into the nippers at a depth of 10-14mm
Installation using brackets for vertical mounting
It is also possible to install the unit vertically with the engine downwards and upwards. Two vertical mounts are used for this purpose. In the brackets there are Ø9mm holes for M8 screws. In the EPP housing, drill holes Ø 12-13mm in front of existing holes in the steel intake grille. The exact location is indicated by special tags on the EPP housing and the figure below. Then insert the spacer sleeves into the holes and fix the brackets. Screw the remaining screws into the nuts under the steel intake grille so that both grips are in one plane. Locknuts under the handles are used to secure the screws from unscrewing
