FLOWAY is a PLUG & PLAY dual-flow ventilation unit equipped with a highly efficient heat recovery unit with plug fans and high performance EC motors, designed to meet all the requirements of recent thermal regulations.

Unit supplied ready to use, prewired, preprogrammed in the factory and supplied with a remote control.

FLOWAY draws clean, fresh air indoors using, on average, 80% less energy than that needed for air conditioning (cooling and heating).

These machines are designed for use in the following applications:

é Service sector Buildings:

o Administrative buildings, Offices

o Education facilities, libraries, community centres

o Cafés, hotels, restaurants

o Shops

o Nursing homes, healthcare facilities

o Collective housing

é All facilities where ventilation is required.

Classic model: 9 sizes, air flow from 300 to 8500 m3/h.

Floor-mounted horizontal unit with horizontal air flows and air connections on the sides.

Vertical model: 4 sizes, air flow from 300 to 2600 m3/h.

Floor-mounted vertical unit with vertical air flows and air connections on the top.

Ceiling-mounted model: 3 sizes, air flow from 300 to 1900 m3/h.

Ceiling-mounted horizontal unit with vertical air flows and air connections on the sides.

The dual-flow air handling unit with heat recovery guaranteeing an

Economical and Durable solution

UseAir flow rate: 500 to 8500 m3/h

* These values are given as a guide for a dual-flow unit fitted as standard, without standard option (electric heater).
