T 400B Professional Dehumidifier for Rooms Up to 160 m²
Professional dehumidifier for large rooms and public spaces
The T 400B Professional Humidifier is a high-performance humidification unit designed to reduce problems caused by dry indoor air in offices, public buildings, retail spaces, museums, production facilities, and other large indoor spaces. The unit is suitable for areas up to 160 m² or 400 m³ and ensures a stable and natural level of humidity throughout the heating season.
Air that is too dry can cause respiratory irritation, dry skin, eye strain, headaches, and increase the buildup of static electricity. A professional humidifier helps improve indoor air quality and create a healthier and more comfortable work environment.
Why is proper humidity important?
The optimal relative humidity for indoor spaces is typically 40–60%. During the winter, humidity levels often drop below 30%, especially in ventilated buildings and rooms with high air exchange rates.
Air that is too dry can cause:
- dryness of the throat and respiratory tract
- eye irritation
- skin drying
- greater spread of dust
- the formation of electrostatic charges
- drying wooden furniture and materials
The T 400B helps maintain a stable humidity level and improve indoor air quality for both employees and visitors.
