I've a set of 1m SDS+ bits that work well, even in the DeWalt cordless SDS

I'd say you'd need a good 7-10cfm for either of those and if you're considering spraying remember that there might be an air-fed mask in the equation. If you're short on space this is a good option: https://www.sgs-engineering.com/stanley-fatmax-b350-10-90v as that's the same motor and pump the "normal" belt drive machines use

All piston compressors are noisy. Box it or outdoor enclosure is all you can do for that... The oilfree vertical you've got aint 10cfm, maybe calculated but no way in the real world. The piston leaks like a sieve on them. Plus IIRC that model is a brush motor and revs it's n*ts off. ^ that one in the piccy above is the same unit that Lidl sell occasionally and is a real sweetie for the money, the pump is overbuilt compared to SIPs and Sealeys of the same class required cfm depends on the type of tool, and whether the demand is continuous or intermittent. Eg for a rattle gun, hose size is more important than pump capacity- it needs a good jag of air to break a bolt loose which even a small tank will contain, but if there's a bottleneck at a hose or fitting well... Tell us what tools they are and how you use them

any chance there's a simple NRV under the allen screw that incoming charge pressure bypasses?

how many pipes go to the buffer/ is there an additional pump associated with it?

leave it all to go stone cold. Start it up and monitor the hot pipe. If it immediately heats but then cools back to warm, then that's low gas for sure.

they do a single valve at 137€ too, but that's not dear really

trying to get hold of someone in HEB would be a direction I'd think? Don't seem to have a website tho

built-up heads like that are more common on hydraulics, I think. Can you get piccys of the whole manifold assy- are the 3 valve just bushed together or is it a single base? what's the thread size of the hose fitting?

Yes. IIRC there was a nominal fee attached but this was discounted off the order.

BPC do everything except work out the duct routes...

can't trust the numbers then as the shiny surface is innacurate. Wrap some tape of some kind around the pipe wherever you're pointing the gun...

how are you measuring the pipe temps?

has the flashing behind the vent stack just drooped a bit?

before going down any 3d printing rabbitholes, how tight in the bleedin thing? How about a nice photo for us to help...

so what's it doing/ not doing?

Howdens Hockley comes in gloss white and is 18mm door? https://www.howdens.com/kitchens/fitted-kitchens/hockley-mirror-gloss/hockley-mirror-gloss-white

this is a problem with PoE, damp gets conductive at dc volts... Remake the plug, give the socket contacts a gentle scrub and try to remove some of the (conductive) black crap in behind them, then goop it up with vaseline or silicone grease as per @ProDave

what is the distance to the boundary?

Tapit fasteners used to have a similar threadform, hammered into a plastic wallplug, but removeable by screwdriver. https://www.carpetfittersshoponline.co.uk/tapit-nails-rws020-46-p.asp

most of my dewalt is the old style but I've moved to the newer batteries to go with a couple of new tools. No hassles with the tools but the contacts on the cheap adaptors aren't great and can get a bit toasty and melty if you push things too hard.

on or under the evaporator core

check the door seals carefully, and if they're all good and you're handy with a multimeter see if the defrost heater is burnt out...

who exactly is the "we"- you or a contractor, and who is hiring the crane in?
