The WANAS 250MN recuperator is a compact ventilation unit with a vertical nozzle system used for ventilation of single-family houses or small service facilities.

It is characterized by very low energy consumption, quiet operation, high thermal efficiency and easy operation. The control panel was designed by a team of engineers manufactured by WANAS and made with attention to the smallest details, equipped with a number of excellent features to enjoy high comfort of use. It is designed for ventilating rooms with an area of up to 150 m2.
Each recuperator is equipped with a weekly touch controller as standard. In addition to the recuperator, you can purchase the WANAS MOBILE CONTROL W-15 module for remote control of the control panel via the Internet.
