AL-KO AT4 series – Your individual ventilation units

Thanks to its modular system, the AT4 series is an all-rounder and serves as the basis for ventilation and air handling systems for numerous applications. It is certified according to several standards, tested according to the specifications of Eurovent and optionally in execution according to ATEX guidelines for potentially explosive environments. The AT4 series is used in the medical, chemical and industrial sectors, as well as for any type of indoor spaces where people meet.

Description

The AT4 modular system forms the basis for air handling units used in hospitals and medical facilities, as central ventilation systems in office buildings, as central ventilation and central air handling in shopping centers and exhibition halls as well as conference centers. It also comes in a nautical version, suitable for swimming pools, spas and wellness facilities. The AT4 can also be used for clean room applications in the pharmaceutical and industrial sectors. A weatherproof design makes installation on the roof (roof-top) possible. The modular design allows a wide performance range with air volumes from 1,000 to 100,000 m3/h.
