What indicators does an overpressure system have?

– There is a green indicator present that can be seen from the workplace whether the pressure relief system is in use and filters are fitted.
– If hydrocarbon detection equipment is available (mandatory when carbon filters are used), it provides an alarm above the 5PPM limit.
– A device is provided that displays the current differential pressure, and gives an optical and audible signal if it exceeds the limit values.

Additional functions of the Freshfilter F3000 controller

Up to three different types of filters can be recognized and displayed on the control panel. Cabin pressure and any alarms can also be read at all times on the F3000. With four simple buttons, the F3000 can be controlled as desired by the operator.

Display with a hydrocarbon meter is optional. The HC value can be displayed on the LED screen. An alarm sounds when the value exceeds 5 PPM (even if the HC is not displayed on the screen). This HC module can also be integrated into the F3000 at a later date.

With the simple cable connection, you benefit from the ultimate preparation. All pressure relief filter systems and controllers have the same connection, so everything can be interchanged with each other. Also, Freshfilter can make the F3000 work on other manufacturers’ machines on request.

Automatic mode

In automatic mode, the controller ensures that the cabin overpressure is at least 100PA. If there is too much or too little pressure in the cab, a visual and audible alarm is audible so that the operator is immediately alerted to potential dangers.
