air compressor pressure drop

hope u didn’t mind me tagging u plse guys

@Flossie @Ratae have made a rough set up and nothing installed , just messing around with ideas

do u think using a 1/2 inch hose would be better to connect between the trap and outlet vs the ridged pipe with a street elbow on the end due to even more pressure drop

will have a thin wood panel round the side , so after i can just put a lid on and push it back under the stairs , along with a suitable place to mount the water trap

also roughed up the pipe for the drain to be installed on the bottom of the tank , put the union there so easy to remove the compressor if req

will of course holesaw the box accordingly for the pipes to be installed neat and tidy

trap will be installed out of the way to allow access to the other outlet

all the ridged pipes are stainless steel and brass street elbow for bottom of the tank , bought a 2 foot offcut of the 1/2 hose so plenty to go between the trap and outlet

full bore lever valves are 3/8 , have also got some 1/2 ones which i think will also be better

yeh i know need to get out more and get the bloody job done , lol

In theory ridged pipe will be fine ...buutt...you will have to consider support and (more importantly) vibration and movement. You will need to fix the compressor down because it will move over time whilst running and the exit hole in the box will need to be larger to allow movement.
I would use hose in your set up to dampen everything upstream of the compressor outlet.

thks for the feedback and most appreciated

good call ref the vibration and using the hose, plus i should be able to drill a hole through the bottom to put some bolts to secure it

it’s still got its wheels on, but they are solid and not rubber and think it would be better to remove them . indeed thinking the same ref size of the holes , got a small box of grommets so i can oversize the holes

the bottom of the box has some insulation but can get hold of some rubber sheet insulation to rest the metal brackets on after removing the wheels

thks again
 
I'd use hose from one outlet to the oiler/trap as Flossie says & for the same reasons. Might be an issue with short piece of hose closing up when you bend it.

The outlet that you don't have the oiler/trap attached to I would remove the pipe barb you've fitted & fit a female quick release coupler (which was there before you fitted the ballvalves) so the connector on the end of any airline you use will just plug into it allowing you to just unplug the airline & roll it up.

many thks, ref the hose i was going to put a loop in it to prevent any sharp bends from occurring

indeed u mentioning the other barbed fitting i don’t know why i put that there,lol, as u say makes a lot more sense to just put the quick release coupling in it’s place

wondering if there will be much difference going from 3/8 to 1/2 full bore lever valves, but as the original outlet is 1/4 every little helps, lol

the quick release fittings are both 1/4 is it worth getting them in 1/2 or is it simply not worth bothering about pls

when i fit the top pieces of thin wood around the top of the box there’s actually tons of room to fit the oiler/ trap inside , only reason being it keeps it all neat and tidy but mainly don’t have the hose going through the box and therefore cutting down any chances of it rubbing

when in use with not have the top lid fitted to ensure it gets plenty of air and also cooling

also got some P clips but think maybe some stronger ones might be more suitable

plus looking at the gauges on the compressor itself and the regulator , when it’s adjusted that surely adjusts both outlets

will also be good having one outlet oil free for tyres etc so isn’t contaminated

once again apologises asking daft questions and appreciate also ur feedback

thks again
 
doing a little bit more , bolted compressor in , drilled the hole for the tank water drain pipe and installed pipe onto tank

pipe going through the hole wont be used , was just used to line it up

left it on its rubber feed as i thought it would be better for the vibration

hope that looks ok so far

hi

old habits ,lol there installed on gas lines , sediment and condensation trap and dont know why but done the same here

same kind of thing can-be installed as a water mains arrester to prevent water hammer

do u think it looks ok so far please , many thks

Only just seen this o_O Some fine advice above :) Watching :):)



"OK" ???? Nah tis betterer than that, tis Over Engineered - my Dad (RN Engineer) would be proud of you :D

many thks, just like to ensure i do a job properly and once, plus first compressor so always like to look after things :D

Yep, , looks good:)

many thks , am going to cut a small piece of the box out at the end where the outlets are , so when the hoses are attached it doesn’t rub against the metal and also sits straight :)

next bit will be to get some thin plywood to fit round the edge , can then attach the water trap etc and allow the lid to be fitted when not in use , appreciate the feedback

:) - yeah I know ;) - "Do it nice, or do it twice" as my Grandad used to say ;)

Though, I doubt the wheels on that box will take much more weight :eek::eek: ...... :D:D

lol, never heard that one before , will remember that :D

will only use something like 4-5mm wood for around the edge, that will be level with the top of the compressor

was wondering that about the wheels, is an old music equipment box but indeed compressor is a lump , 38kg

was thinking about mdf but always found it terrible trying to get a decent fixing, unless i drill holes and use nuts and bolts to fix the water trap / oiler , thinking also about getting some small rubber sheet to put between the wood and oiler to reduce the vibration from the compressor :D
 
just messing around the box abit more

measuring the wood i need for the side in order the lid can be fitted when not in use

also cut out the end to allow the hose not to touch the wood

also roughing up the position of the trap/oiler, wished to see if the hose would loop ok without kinking

none of the fittings /pipe have been made up and just removed the handles ready for when i tighten up the full bore valves

also checked to ensure the compressor was sitting level inside the box because of the oil and i tightened up the bolts evenly

Looking good :) - just an idea, but you might like to put a bit of strength back in where you've cut the ali extrusion by making up some plates along the lines of :-

And get that level right Man :eek::rolleyes::D:D

thks, good call, have got some flat angled brackets which i could fix inside which will strengthen that back up again :)

must get an adjustable bubble , lol, just got to nip up the right hand nut to bring it down a minuscule amount , :cool:
