The newly upgraded active displacement ventilation system features an optimized design for efficient air exchange and balanced air intake and exhaust, which precisely maintains equal air pressure inside and outside the booth. This fundamentally eliminates the uncomfortable ear pressure users may experience when entering or exiting, keeping the interior air fresh and comfortable at all times. Integrated with an intelligent infrared (IR) sensor, the system achieves dual breakthroughs in convenience and energy efficiency: the sensor detects human presence the moment a user steps into the booth, instantly activating ventilation and lighting without manual adjustment for a seamless transition into work mode. When the user leaves, the sensor automatically turns off the lights and reduces ventilation power within a preset time, effectively conserving energy. Additionally, users can switch to manual mode via the power button to flexibly extend lighting and ventilation duration, catering to personalized usage needs.
To balance ventilation efficiency with quietness, the booth is equipped with a centrifugal fan for air intake. Unlike conventional fans, the centrifugal fan adopts a fixed drum structure with multiple impellers. It generates high-pressure airflow through radial air delivery, enabling more stable air circulation at lower rotational speeds and significantly reducing operational noise. Even in a quiet exhibition hall, it operates without causing disruptive sound interference.
The system is further enhanced with an automatic refresh function: it activates ventilation for 5 minutes every 30 minutes, continuously keeping the ducts and booth interior dry and odor-free, ensuring the space is always ready for the next user. This ventilation system upgrade allows HECOR Soundproof Booths to strike the perfect balance between air circulation, comfort, and energy conservation in enclosed environments, redefining the comfort standard for enclosed office spaces.
