4.5kw - electrically heated. Air curtain PA1508, is primarily intended for small openings, such as kiosk and service hatches and cashier benches where a long, narrow air flow is required. This creates a temperature separating air barrier that prevents cold air from pushing in and hot air from flowing out. PA1508 also gives additional heat and in this way also improves the working environment. With its compact construction and timeless design the unit is easy to place in any doorway. The intuitive controls are easily accessible, placed on the gable end. The front can be finished in any colour to perfectly match the environment.
