fez air!

nice work man and its also cool with two compressors work so much better lol:triumphant:
 
If you have a donor compressor a monkey can build a home built compressor. You remove the old noisy compressor from the tank, connect the new quiet compressor, the same way. It's only 2-3 wires, and 1 air line, simple.

ok then i guess ill have my wife build one... shes pretty good at peeling bananas:acne:
 
not so much the skills..... i got an electrician at work to wire the 2 comps together.... and a plumber just overlooked the copper work and made sure stuff was air tight.... you could do this whole thing with compression fittings just like i have on the blue nylon tube.... so simple... screw the nipple coupler (oooeeeer) in to the port.... screw in check valve screw in compression fitting, push in hose... pretty simple connections and can even be done by a "sophisticated monotone moron" like me hehehe.

fez if you do not like your voice,, you should try the new product im coming out with... its called a monotone enhancement harmonizer..... it makes your voice sound like your some kind of radio personality...

i use it all the time at work and it has really helped my confidence.. it has also helped me grow more hair on my chestnuts:surprise:

haha good I'll have 1..... your listening to fez on radio 6 goooooollllllllldd
 
Awesome job mate it looks and sounds sweet! I think we have 'Compressedairtutor.org':)
 
Don't want to contradict you Andy, but if the fridge compressors are the same in the UK as in America, the oil as a strong odor and can be replaced by ordinary mineral oil found in pharmacy, no holes needs to be drilled you only need to tilt the compressor, the oil will exit from the input lines (this will take a couple of minutes and you will need to tilt the motor almost upside down).

If you are careful and recover the oil drained in a measuring cup, you will know the amount of new oil to add, and just need to put it in a container, put a tube from the input to the container and start the compressor, it will suck the new oil in. If there are two input lines, you can block the other one with your finger so it increases the suction on the line in the container, and your done :)

I do agree with you WhiteKnight that the oil used as a certain smell to it! However when I have previously took the tops off these sealed compresssors I have found that the inlet pipes are not flush with the inside wall and can be poked through by upto half an inch or so making it impossible to fully drain the oil, hence the reason I mentioned drilling holes and not drilling holes, and dedending on the point where these pipes enter, that half an inch can be quite a lot of oil! I have thought about using thin PTFE pipe attached to a syringe and poking this in the air inlet and sucking out the old oil but you can not be sure you have reached the bottom of the compressor unit!

Unlike the US or Canda we cannot walk into the local Boots Chemist (Pharmacy) and ask for a litre of SAE40 compressor oil (they would probably look at you like a moron, ask if its made by Johnsons and offer an alternative of baby oil) and I do find it dificult to get the correct type of comp oil locally (Machine mart do stock it for their range of Shush compressors but Machine Mart prices being as they are they would want a kidney and a cornea in exchange!) . I use the BAMBI SB-46 oil at £20 for 1 litre inc P+P it is made for these types of comps and I believe is a slightly lower viscosity than normal comp oil and is non toxic.

Fezzles .... Just watch the vid .... That is a piece of super dooper kit mate! How fast does it fill the tank from empty to switch off?

Until you get used to it just keep an eye on how warm the comps get (part of working out their duty cycle). They will get quite hot if run for extended periods continually. Tyr working to a duty cycle of no more than 50% i.e they are off as much as they are on or better ... 25% would be ideal and this was probably about the duty cycle of my old dead Bambi!

Yet again ... congrats mate that is an excellent job! :triumphant:
 
Thanks bud. .... from empty to switch off at 100psi takes about 4 mins 30..... I hadn't used it for painting yet. ... but with output at 25psi on 25 litre tank it should not be on to much. ... hopefully I should be able to hey a bit of painting done tonight so I'll see how it goes. ..... only one prob so far. .. getting s trickle of oil in first moisture trap. ... could it be levels are to high?
 
The oil levels will be correct or slightly low as they were factory filled. I believe these types of compressor do chuck out a bit of oil but as I said previously, as it was a closed loop system it always ended up back in the compressor. Just keep your eye on it.
 
That looks superb, really like the air filters, where did you get them from?!
 
hey jack.... i got them from ebaY.... just search mini air filter.... bout £3.50 each
 
Just read this thread and all i can say is thanks guys! I`ve been collecting the bits to make my own comp and his had answered a lot of my questions, by the way Great job Fez
 
I was wondering if you left the factory oil in the comp's or if you replaced with something else?
 
It's still got factory oil in at the moment Bro. ... the first moisture/oil trap collects about halfa teaspoon of oil every 3 hour painting session ..... considering that's from 2 comps is not losing very much but I'll give them an empty and top up eventually with proper comp oil.... but at the moment it is running fine..... fyi last night I was spraying fabric and was spraying at around 55psi and comp handled it perfectly with around a 20% duty cycle
 
Huh. Mine never pushes oil into the trap. And I never seem to find it in the tank. Wonder if I am not putting enough oil in or if my discharge tubes having an upward loop is handling it.

when I build mine I will put a 12" rise on the outlet. We do this on roof units to keep the oil at the unit. This may be something to look into for these diy compressors
