Freshfilter F4000 Controller

Quality in a small size and controlling pressure has never been easier.

This modern controller ensures the most optimal working environment in the cabin. The controller, which is located in the cabin, keeps the pressure in the cabin on automatic setting constant above 100 Pa. This ensures that polluted air does not enter the cabin even at wind force 7. The controller is designed so that the operator can read relevant information directly.

Measuring only 129 x 78 mm, the F4000 fits seamlessly into the interior of a machine or vehicle. The F4000 starts up in automatic mode and will immediately operate the protective ventilation system in the most optimal settings. In case of notifications, for example, the operator can easily operate the controller using the touch screen or the four colored buttons.
If the pressure in the cabin is not achieved, or is just too high, the operator is immediately alerted to potential danger. The F4000 gives an optical and acoustic alarm after which the alarm notification can be read directly from the screen.

Optionally, the controller can be equipped with a sensor (for example, HC, NH3, H2S and CO2). When activated carbon filters are used, a
sensor in the controller becomes mandatory in most cases. This sensor measures real-time air quality in the cabin, if the limit value is exceeded the controller will alarm. The blowout of an activated carbon filter can be detected much earlier than an operator can.

For the safety of the operator, it is important to keep the sensor working properly. Annual testing/calibration of the sensor is therefore a must. During an annual inspection of the protective ventilation system, Freshfilter can calibrate the sensor directly. This prevents Freshfilter from sending a machine into the work field temporarily without overpressure.
