- KP/DB Air Curtains
KP/DB air curtains provide an effective air barrier for large doors, gates and other external building openings, helping to protect indoor spaces from the uncontrolled inflow of outdoor air.
Designed for shops, retail premises, workshops, warehouses and similar applications, they help reduce unwanted air exchange through open doorways, supporting more stable and comfortable indoor conditions.
The air curtains are designed to draw in, recirculate and heat indoor air. They can also operate as ambient (unheated) air curtains where heating is not required.
The air curtains are suitable for doorways, gates and building openings from 2 to 4 m high.
- Horizontal (Over-Door) Installation
Installed above the doorway, with multiple units mounted side by side for wider openings. - Vertical (Side-Mounted) Installation
Installed at either side of the doorway, with multiple units combined where required for larger openings. - Recessed (Suspended-Ceiling) Installation
The air curtains can also be supplied in a recessed version designed for installation in suspended ceilings.
PRODUCT DESCRIPTION
The air curtains consist of the following components:
- A powder-coated sheet steel casing with a full-length discharge slot
- A water heating coil or an electric heater
- 2 or 3 double-inlet centrifugal fans
The air curtains are suspended from the ceiling using threaded rods attached to the casing.
The air curtains are available in two sizes and six variants, differing in the number, size and rotational speed of the fans as well as the length of the discharge slots.
The electric heater is equipped with overtemperature protection to prevent the maximum permissible operating temperature from being exceeded.
OPERATING CONDITIONS
Water-heated models are designed for operation with heating water temperatures up to 150°C and operating pressures up to 1.5 MPa.
Electric-heated models operate on a 400 V three-phase power supply.
When selecting an air curtain, an air velocity of at least 3 m/s at floor level should be maintained to ensure effective air protection across the opening.
