Zbroia Hortitsia Filling Issue

[RevonocAce]

Good evening, friends!

I recently acquired a 330/180cc Zbroia Hortitsia in .22cal. It took me a little while to figure out how to fill it properly, and turns out, there is something abnormal happening. I am filling it with my yong heng and the compressor wants to max out pressure as if there is no air getting in the tank. But, if I very slowly bleed the compressor so it doesn’t red line, the gun fills. I know this is not normal, but I don’t know what the heck to do about it. The same phenomenon occurs when using a hand pump, and I just pump it a bit slowly so as not to red line that one as well. 


If someone knows what’s going on, I’d greatly appreciate some help. Thanks!

Maybe it has a slow fill valve in it. Some guns come this way, and it’s completely normal.

I had the same thing happen with my Diana Outlaw, same style filling procedure. Sometimes the fill probe gets picky where it’s placed, maybe align it perfectly if you haven’t done that already. One thing I also tried was loosen the front fill gauge to bleed out the whole tank/tube and it reset the fill valve. If that doesn’t work maybe reach out to Joe Broncado the “Airgun Scientist”, he’s a Zobria dealer and can hopefully help out specifically with your rifle.

They have a slow fill valve in them ,my kozaic takes a while to fill no matter what the pressure in the fill tank is

It would be best if your gun and filter were placed above your compressor. This would help to keep the moisture out.
