CX2500 has an internal fan. The unit is mounted in the ceiling.
Ionization, Ozone and VOC levels, Humidity and Air flow all are independently controlled from a wall mounted box with LCD display (Remote Control). The fan level is controlled automatically and adjusted to Low, Middle or High level by the controller. The controller is directly connected to a computer through RS485 code, for visual monitoring of all above functions.
The room volume in square meters ( m2 ) indicates the approximate room size this unit can handle, based on a room height of about 3 meters. This may vary with air quality and humidity.
