Re: Compressor purchase
Female fittings on the compressor, male on the tools.
I used to buy most of my fittings from RS Components, they didn't seem to be too expensive for things like that. Good makes to look for, other than PCL are Legris, Festo and RS Pro (if buying from RS).

Re: Compressor purchase
The female fitting has a seal-off valve that closes when no male fitting is plugged in, which is why female bits always go to the air supply side. Then you can disconnect anywhere and you don't have a hose whipping around as the tank empties through it.

Re: Compressor purchase
Thanks guys. So, I reckon need these parts to get me going, doubling up on the connectors:

Re: Compressor purchase
Yes I'm saying they don't. If you operate the release on the PCL it will simply pop out. Of course they may do versions that have this safety feature as well, in fact they probably do, but it's not as standard.

Re: Compressor purchase
I seem to remember from many years ago, when I was involved in engineering, that blowing compresssed air onto the skin could cause an 'air embolism' which could prove fatal. I don't know how great a risk this is or if I am mis-remembering. Perhaps other members would know about this.

I frequently repair seriously dust encrusted power supplies. I used to blast them with the compressor at the place I used to work, but this can be a serious health hazard unless a mask is worn and IMHO not really something that should be done inside a workshop, or even by open doors and windows. For my home workshop, I find a strong vacuum is better. The potentially harmful crud gets removed to a safe place instead of being blasted around the immediate environment. I have a selection of small soft brushes that enable me to dislodge the dust in inaccessible areas and use a powerful restricted nozzle vacuum to then remove it.

Re: Compressor purchase
The unit arrived, safe and sound, double boxed, no damage. See photo below. Regarding its output connection, it looks similar when looking 'down the hole' to the PCL one that I will be fitting to the hose that I bought. Maybe it's a Chinese equivalent? Can anyone tell from the photos? I don't have a male connector to check as Screwfix were out of stock today, get them tomorrow. Thanks.

Re: Compressor purchase
If it's Chinese, it might be one of these:
https://tinyurl.com/ybfuyxbj The two systems look similar but don't fit each other. I use Chinese ones on my lash up, as I had a few on some cheap aldi-lidl style air tools anyway. If you change yours out, don't throw it away - I'll give you something for it! |

Re: Compressor purchase
With these taper threaded connectors, is it necessary to use gas PTFE tape or, as one would think, being tapered do they seal ok?

Re: Compressor purchase
Use regular ptfe tape. The taper thread acts as a way to physically lock the thread, but this isn't enough to seal it. Parallel threads use flats to land against to lock the thread as it tightens. You would still use ptfe tape on a parallel thread.
Loctite 577 is a good example of a thread sealant and thread locker for parallel threads with no mating faces to lock. You can still use ptfe but would need more.

Re: Compressor purchase
I have both gas and normal PTFE tape. You're saying the normal PTFE, not the gas one? why?
I also have threadlock. I could use that? Basically which of the three 'sealants' that I have is the best to use? Cheers!

Re: Compressor purchase
Have never needed to use the gas one for air, but you can do if you have it.
You would only use thread lock if it's the type for sealing also, such as 577, rather than the type only for fasteners. In your case with tapered threads, use either of the ptfe tapes you have.

Re: Compressor purchase
From Sunday Lidl are offering a range of air tools and accessories. Some of the accessories look as though they might be quite useful and at those prices no great loss if they are not.

Re: Compressor purchase
Looks good, thanks.
Incidentally now that I know more about different connection types, it appears that my compressor came with a Euro type outlet connector on it, and all of those units at Lidl seem to use Euro too. So it looks like Chinese compressed air equipment uses Euro. Following advice from people on here I have kitted myself out with PCL Airflow Standard connectors. I have also bought a converter connector that will enable Euro male connectors (eg on other peoples' tools etc) to be connected to my 'system'. I am still waiting for one connector to arrive, so soon I will be firing up my compressor.

Re: Compressor purchase
There is one thing that I want to clarify before I switch on. The operating instructions say that the pressure regulator should be set at its lowest setting, ie turned fully anticlockwise. Hmm. Having fallen foul of erroneous Chinese operating instructions many times in the past, this made my 'ears prick up'. Surely this should be clockwise? See photos below. The way that regulator control is configured, then screwing it clockwise would appear to be the way to 'block off' that airway? Of course my 'logic' may be wrong. I don't want to switch it on full blast at my first attempt!

Re: Compressor purchase
I have heard a story of someone that died after the air went through one of the little ducts in a carburetter and into his finger.
