How to change the filter felt of a sera air membrane pump


I own a sera air 550 R membrane pump and wish to replace the filter felt in the air intake, since it is very dirty and pump performance goes down. How can I remove the rubber stopper in order to replace the felt?

the rubber stopper is only plugged in and can be lifted with a little screwdriver or the like.

It works in the same way for the smallest model (air 110 plus) of the following model series. The filter felt of the larger models air 275 R plus and air 550 R plus is located inside a drawer-like module that can be pulled out.
