Europlast EER125S air heat exchanger, diameter 125 mm, with wall switch. It is intended for the continuous renewal of the air in the space. It features a ceramic exchanger (Regenerator) for heat recovery.

• Operating Cycle: In two steps of 70 seconds each.
• Step I: Air extraction for 70 sec, where the heat exchanger accumulates thermal energy.
• Step II: Fresh air intake for 70 sec, where the exchanger transfers the heat to the incoming air.

The step exchange achieves air renewal with minimal energy loss, providing up to 90% heat recovery.

It has a double wall switch for on/off and speed selection. It operates quietly with power of 1.8 and 3.4 Watts at the respective speeds. It supports continuous operation 24 hours/365 days.
