• The air curtains are designed to prevent the cold or hot air streams from outside into door openings or gateways.
• The height or width of the covered areas ranges from 2 to 5 meters.
• The air curtains are suitable for crowded premises with increased traffic load.
• Designed for application in manufacturing premises, stocks, garages, car service centers and car wash shops, shopping malls, super- and hypermarkets, conference and exhibition halls, and other premises.

• Air curtains are available in 4 standard sizes depending on the capacity.
• The curtains and their components are made of galvanized steel.

• Air heating is effected by means of water heating coils or electrical heater.
• If water serve as a heat medium these curtain types are suitable for the premises with the indoor temperature not below 0^оС only.
• Air distribution is performed through the slit sections.
• The standard slit sections are 1 to 1.5 m long that enables easy selection for any door opening.

• Rectangular duct high pressure fan is applied in air curtain.
• The supply air is filtered and then supplied to the premise through a narrow slit which ensures the outlet air speed increase and its correct operation.

OVERALL DIMENSIONS:

FAN MOTOR

• The impellers with forward-curved blades made of galvanized steel are powered by four- or six-pole asynchronous motors with external rotor.
• The fans with such turbine modification are featured with relatively high pressure differential and high air flow capacity.
• For thermal overheating protection the thermal contacts with the leaded terminals are built in the motor winding for connection to the external protection devices.

• Both horizontal and vertical mounting is possible.
• In case of horizontal mounting the air curtain is fixed above the door opening and creates the air stream vertically downwards along the whole opening width.
• In case of vertical mounting the curtain is fixed at one side or at both sides of the opening and the air is streamed horizontally.
• One vertical curtain covers 10 to 12 m² space and for larger surfaces the air curtains at both sides shall be installed to increase the effective area.
