info Zetor 3340 Air Filters

[Robertzetor3340]

Hi Everyone,
I checked out my 1999 ZETOR 3340 Air Filters and they were very clean looking.
But, the smaller inner filter has what looks like maybe a torch was used on it to remove part of the plastic paper.
I do not know why/how and/or if someone would melt part of the plastic filter paper away.

Does anyone know a reason or what would cause this mystery to happen ?

Thats not a normal thing with your inner safety filtre.

But its without problems to find and buy. No problem.
