Inline regulator/filter...?

[The Z'eer]

So far I've purchased 1/4" PCL XF and the hoses which arrived this morning...

one to link to inline regulator, and the other connecting to the gun.

I now need to chose an inline regulator with oil and water filters. Unfortunately I don't have any knowledge regarding this equipment. With regards to what's available here https://www.spraygunsdirect.co.uk/i...rs-gauges.html?dir=desc&limit=all&order=price there seems to be a lot to chose from, but what will do the job suitably? Haven't decided upon a budget as yet.

Also, do all of those filters include an oil and water trap? Also quite a few seem to mention the temperature for which the unit can cope with, what does this mean?

Thanks

just buy a filter regulator not one with an oiler there not needed . probably spend no more than 60 quid for something decent a couple of members will probably post up something decent at the rite price

Thanks for the info there, but might I ask what an "oiler" might be?

its an inline oiler for using with air tools and lubricates them. there not needed for intermittent use and u need a separate airline to use one . if u have air tools . just 3 drops of oil
at beginning of use and a few drops when finished give it a quick run and it stops your tools going rusty due to moisture inside if not used for long periods

Ah! I see. I don't have any air tools as yet, but thanks for the advice there. Do all air tools require an oiler then? And thanks for the instructions regarding the application of oil for the tools.

You wont need to worry about the temp requirements unless you are fitting it inside a paint booth/oven that bakes the paint.

That's pleasing to hear, thanks for advising there. Isn't compressed air naturally hot though?

In an industrial situation it normally passes through coolers to help remove moisture.
The regulators for ovens need a high temperature rating as plastic parts can start to melt from heat when the booth is set to bake, if not suitable.

I see, obviously this isn't a concern for a domestic set up then, thanks for the info there

Been reading through air system requirements http://www.mig-welding.co.uk/air-system.htm an oil and water filter is needed. This I believe is a single stage filter https://www.spraygunsdirect.co.uk/i...et-filter-regulator.html#sthash.pz9cEYfS.dpbs does this mean it will only filter out moisture and not oil?

Hello
Are you planning on using comp for spraying?

If so then 10 metres of copper for droplinks and cheap £13 silver line regulator (eBay 182256227800), works great for me, i'm spraying regulary and using airtools as well with no oiler as mentioned, I hardly get water in regulator, most of the moisture/oil it gets captured in the first and second droplink.

Thanks for the information there

Yes, the main intention of usage is for spray painting. I'd really like to use hard piping with the compressor, and as you say a great deal of moisture is removed. Unfortunately the location and environment doesn't allow.

This is why I need as much information with regards to what in line regulator/filter is needed.

if you're using 35m of airline, you may get a significant drop in pressure between your compressor and air tool/spray gun. I use a home made desiccant dryer to try and remove water from the compressed air. (with other filters and regulators)

with my wolf dakota compressor as shown here

That's a little concerning, why do you think a pressure drop will occur from using 35 metres of air line?

Thanks for the link a few questions regarding the modifications, I'll post on that thread later.

its policy to use 10mm bore pipe and keep as short and strait as possible to get maximum cfm and pressure at your tools without loss. curled up pipes tend to harbour moisture then chuck it all out at once don't get too hung up about it though just get started and see how it goes otherwise your head will be done in with all the info

Yes, there does seem to be a fair amount of information to take on board, sometimes baffling!

The hoses are 9.5 mm in bore not 10 mm. Hopefully the 0.5 mm won't effect the results too much.

I may have to re think the location of the compressor and just run the 15 metre hose if pressure drops and other issues will be apparent. Thanks for more info, I'd rather know now than later

on the subject of pressure drop, this is my 1.8mm lvlp (low velocity low pressure) spray gun,which at 30psi just uses less air that compressor an supply at will work all day at 30 psi.

I use pcl xf fittings and two 10mm hoses, 15m and 10m long. so I joined them between the compressor and the spray gun (hose lenght is 25m in total) and this is the result with the regulator on the compressor (the one on the left) showing 50 psi. the one on the spraygun shows 32psi. If I connect the spraygun straight to the compressor its shows 50 psi. for this spraygun its not an issue as its normal operating pressure in 20 to 25psi. on the other hand if you've got a air tool that requires 90psi to operate at its optimum, you might only get 60psi with the longer hoses,which may limit how well it peforms

Thanks for posting the information about the pressure drop over a 25 metre air line. I'm glad I'm aware of this now before I spend any more cash on unnecessary equipment.

On your results I think I'm gonna need to place the compressor far closer to the work area. Also I think I'll have to incorporate a small hard pipe system as well (despite never attempting any kind of plumbing before).

 

[Cobbler]

One answer might be, move the regulator away from the compressor & on the end of the run, then use a short hose to the spray gun. This would take high pressure air closer to where it's used, then keeping the regulated pressure constant as there will be less pressure drop due to the short hose. Obviously this won't work with high pressure high capacity air tools, but should be ok with a spray gun I would have thought.

I hope this makes sense to you, it makes sense to me as I write it, but then it would, wouldn't it
