Took delivery of an Alkin W31 today (yes, I am STOKED
). Per my request, the fill whip came with a female Foster since my tank has a DIN 300 to male Foster adapter on the valve. Keeps things simple.
As currently equipped, can fill any tank with either DIN 300 or a male Foster (using the adapter on my current tank), but would like to be able to fill SCBA/firehouse fitted tanks as well, for a couple reasons:
Will post another thread extending that offer, not sure yet what forum is most appropriate- this one, General Discussion, PCP, Classifieds (not selling anything, will fill for free).
Thinking that with a firehouse to male Foster adapter, and the DIN 300 to male Foster I already have, should be able to fill most tanks that PCP shooters would own. Would appreciate confirmation, or advice on alternatives if I’m all wet.
Btw, kudos to Alkin USA & FedEx – ordered the compressor Tuesday late afternoon, arrived this morning. As you can see from the photo, great pains were taken to emphasize careful handling. Apparently the FedEx freight driver took it to heart; nary a hole, tear, or dent in the cardboard covering.

- Will eventually get another tank, likely a used Scott firehouse tank from a reputable source.
- Want to be able to provide fills for anyone in my area who is in to (or thinking about getting in to) PCP airguns
