You are making the calculation on the flow of the compressor, actual the flow in the air line will be the demand of the tool you use and often ts much higher.
As others have said with tools like an impact gun you fill the receiver and use the gun in short bursts until the pressure falls then pump it up again, no single phase compressor can keep up with high consumer tools like impact guns or paint sprays its just a matter of compromise.
The more storage capacity you have the longer the bursts will be,

They are pretty cheap and you can find them on TbayView attachment 142264 View attachment 142265 pic of clip, pic of crimp method or use hose clips if you like old school

My own compressor is about the same size as the one featured & it runs HVLP gravity feed guns fine. I currently have 4 SMART repair size guns - a mix of SATA & Iwata 0.8 & 1.0 setups - and one full size with a 1.4 setup.
Haven't used a suction feed in years so I've no idea whether they'd work.
ah nuts
air line fititngs turned up today and they weren’t the euro ones, think there called pcl
may i ask , does anyone have a chart or pics of the different types of quick release fittings plse
established by existing connectors on the compressor are of the euro quick release type
wondering how many different types there are so i don’t make the same mistake again
as on the compressor it has 1/4 outlets and going to fit
1/4 to 1/2 fitting
then make up a short 1/2 hose to go into a water trap , going to secure the water trap on the side of the box
other side of water trap 3/8 and onto 3/8 hose to air tools
thks so much once again

The only types I'm aware of is euro, pcl and shnider (wrong spelling! But something like that) .
If you fit 2 pcl females to your compressor that's you sorted isn't it?

thks so much, for the help
the pcl fittings i got, won’t go into the quick release connectors on the compressor , which means that must be a euro type
took a quick pic
the fittings at the bottom, none of them fit , top ones do fit
just sitting here looking at the fititngs and what i need
just a case of finding out what types there are , am useto fittings from plumbing but not these ones, lol
so need to go
from compressor where i’ve removed the 1/4 quick release fitting
then 1/4 to 1/2 , reducer male iron
1/2 female euro quick release
then euro fitting to go into the above fitting - ribbed for hose
then other end of hose to water trap , fitting ribbed - euro
do appreciate it

Throw the euros away and fit pcl throughout.
It's less pain all round.
All the cheap compressors come with euro including the one my mate got but he got all euro fittings instead.
But you've already got the pcls unless you can send them back balanced against the cost of two new pcl couplings in place of the two euro ones on your compressor.

Just had a quick look on eBay about a fiver each.
NOT 100 series though! They are different again for high flow applications.

thks, reason i wished to stick with euro was because there not so restrictive as the pcl in looking through them
have spoken to the seller and said he will swap them to euro types for me
just wondered then there all the same , the compressor came with a kit, ie sprayer , tyre gauge etc etc and there all euro fittings
thks, will have a look so i know what these 100 fittings look like

That makes sense then if all your tools are euro to.

The 100's won't fit your euro fittings and are pointless on such a small compressor.
just trying to make everything simple and not having to mess around
have found a fitting which i think might work better , can then go straight from the compressor to the hose then onto the water trap
other quick release connector i could leave alone, then that isn’t going through the combined water trap / oiler so no risk of contamination of the air line hose and use for things like tyre inflator or blowing off brakes etc , then not spraying a mist of oil everywhere from the oiler , if that all makes sense
plus this is the combined water trap/ oiler i got

I'm not super keen on fitting the hose directly to the compressor Gary, I would stick a 1/2" ballvalve on the compressor and the barbed hose tail to that. You can then isolate everything downstream quickly if a hose bursts for instance.
ah, that makes a lot of sense and indeed a very good point
see, that’s where experience comes into it
plus , am thinking , only one of the outlets are regulated , so think i can use the un regulated side into the water trap that has a regulator , then use the compressor regulator for the other side
Seconded.
I'd consider fitting a ball valve to each of the connectors on the compressor between the connector & the compressor itself so you can isolate either or both sides
agreed and hands up i didn’t think of that until @Flossie kindly advised me
have ordered 2 x full bore lever valves and correctly rated for air and 2 x stainless steel male iron 1/4 - 1/2
also thks again and great getting knowledge like this and appreciated
