Europlast EER150S air heat exchanger, 150 mm diameter, with cable/plug, on/off switch, and cord for speed selection. It is intended for continuous air renewal with minimal heat loss.

It features a ceramic heat exchanger (Regenerator) for heat recovery. The operating cycle is performed in two 70-second steps:

• Step I - Air extraction for 70 sec: The fan operates to extract air, and the heat exchanger accumulates thermal energy from the warm air flowing out.
• Step II - Air intake for 70 sec: The fan direction reverses, and fresh air is drawn into the space. The heat exchanger conveys the accumulated heat to the incoming air.

The steps alternate while the exchanger is in operation, achieving air renewal with minimal energy loss. Up to 90% heat recovery.

The device comes with a cable and plug and a switch for turning on/off, as well as a cord for selecting one of the two operating speeds. Silent operation and long life cycle, suitable for 24-hour and 365-day operation.

Easy installation on external wall and capability of mounting on walls with a thickness of 30 to 55.5 cm. It features washable filters and a quality external grille made of ABS plastic. Energy class A and protection rating IPX4.
