Will longer pneumatic hose reduce air pressure noticeably?

[boscawen46]

I am using a Hydrovane 501 compressor with a Minigraf 4 underpinner in my workshop. As the weather gets better I want to be able to wheel the underpinner into the yard outside my workshop but leave the compressor in situe. This would mean needing a hose of about 35-40ft.
Will this noticeably affect the pressure from the compressor?
Thanks in advance

As long as there are no leaks, and the hose is one long length it will be fine.
I have a coiled hose that is around 5m long when stretched out and there is no noticeable decrease in pressure.

Off the top of my head I can't remember exactly how long my off the shelf hose was but it was quite long and it cames ready fitted with the hose fittings, Whatever the exact length it is, I am quite syre it is tens of metres long and mine was not the longest available. It don't think that they would bother making such long hoses if there was going to be a problem. I'm pretty sure that you can buy ready made hoses at 30 metres long and 30 metres works out at 100 feet. How long do you think that you need? How about an electrical extension lead and take the compessor outside as well, if you think that there is going to be a problem!

You will have no trouble whatsoever. Think of the extra hose as a large blister to your receiver/tank. The compressor fills up the tank and hose with compressed air. You start using the air, so the compressor kicks in and refills to keep the pressure constant. The Hydrovane is more than competent for the job.

That's what I was thinking. Makes sense to me!

I would think that the more hose or pipe you have, the more compressed air that your system will be able to store between cycles of running the pump. it essentially "increases" the storage tank size. So more hose would mean a more constant level of pressure, not a lack of it.

We have a very small Silentair compressor, and I have 3 50ft lines connected to her, going to different places (Vnailer, Valiani CMC, Fitting table). I have never had any problem with that setup.
