Balanced ventilation unit EASYVEC® C4 PRO

centralizedmulti-roomresidential

Overview
The EasyVEC® C4 PRO is a range of exhaust box fans designed to provide efficient, low‑consumption ventilation for multi‑occupancy residential buildings. The design facilitates installation, configuration and maintenance while enabling integration with heat‑recovery water‑heating solutions.

Product summary
EasyVEC® C4 PRO ventilates multi‑occupancy residential buildings to ensure indoor air quality and protect the building structure. When combined with the T.Flow® Hygro+ / Nano domestic hot water solution, heat from extracted air is exchanged and reused to heat domestic hot water. The Micro‑watt constant pressure controller reduces heating costs compared with non‑regulated units. AldesConnect™ Pro enables remote monitoring for faster intervention in the event of faults.
