Iris dampers
GBL
Description
The GBL iris dampers are essential for smooth control of the duct air pressure. The lever and the iris regulating plates mechanism allow smooth adjustment of the diameter of the orifice(opening). The iristype closure allows throttling of the air flow without turbulence or induct noise. The GBL iris damper can be installed both in air supply and air exhaust ducts. Each Iris damper is provided with two manometer connections. The GBL can be opened to the full clear diameter for easier cleaning of the ductwork. The iris dampers, however, cannot be sealed shut (the maximum closing ratio is ca. 25% of the nominal clear diameter).

The HomEvap adiabatic humidifier is designed for domestic mechanical ventilation systems with a maximum airflow 600 m3/h. Filtered water (Legiosafe®) naturally evaporates on a special matrix, and then the humidified air is distributed to the ventilation duct system and to the connected rooms. The humidification process is regulated by a wireless room controller and a duct sensor. Builtin PTC heater compensates for temperature losses caused by the evaporation process. The housing is made of EPP, while the matrix is made of fiber glass.

GCR swirl diffuser is equipped with fixed blades bent at a constant angle. It is made of galvanized steel sheet, powder coated in RAL9010. Swirl diffusers ensure mixing of the fresh air stream with the room air, which is recommended for supplying cold air. They provide a stable flow of the stream and are intended for rooms up to 4m high, for example in public facilities such as hotels, restaurants, office buildings. The perforated plate leads to rapid air flow velocity decrease at low noise levels.
