discussion Air Compressor

[Guest]

Ok guys, i figure im going to need to get a compressor sooner or later

can you guys please tell me what i need to look for

eg: what psi range, price, make, model.

i know i need a regulator and water trap but even so they can be baught seperatly.

just need some general advice, tips.

let me know what compressors you guys have, how you rate them and what would be ideal for me

and a point i would like to ephesise...i dont really want to be spending a great deal of money on one....deffinatly not more than £100

so if anyone can point out a decent one on ebay or know anyone who is selling one/seen one at a regular stall at a boot sale or something that would be great!

thanks.

Richard

***There will be more on e-bay,just place 'Diaphram Compressor' into the search box when you are ready for one,I think this chap is dealing in them,mine cost £150 all those years ago,and has no water trap or pressure gauge,so this is a really good buy,they are so quiet as well.

thanks Barry, that looks and sounds great!unfortunatly....no money untill next month, hopefully there will be some more up then!!!

 

[Guest]

Good Grief!!, you can't go wrong at that price can you?

I'm sure mine cost somewhere in the region of 120.00 quid a couple of years ago. Still, I bought it from an art shop and they have always known how to charge!

 

[Guest]

yes it does seem like a very good buy, thanks alot for the point in the right direction.

I’m getiting back into scale modeling after a break of some years, and thinking I should finally get around to purchasing an airbrush and compressor after seeing the results that can be achieved.



I’ve narrowed down the airbrush choice but have a couple of questions regarding the choice of compressor and regulator / filter etc.



The compressor I’ve purchased is a Werther International

The manual states:



“Output is 70lpm free air delivered, maximum pressure is 50psi (3.5bar) but running pressure is less as an air bleed must be fitted to this machine and ultimate working pressure depends on size of nozzle assembly used. 150 watt shaded pole motor, thermally protected, on/off switch, for the occasional user (not continuously rated). “



I’m a little unsure of what is meant by an air bleed – it seems the regulator which can be used is one of two types, the regulator can either restrict the air to lower the psi or alternatively bleed some of the air to the atmosphere at the regulator and limit the air flowing to the compressor. The images below show the two types.

My question is – what is the difference in these types of diaphragm compressor available, all seem to be designed for airbrushing whilst some seem to mention this air bleed thing.



What experience do you have regarding these compressors? Any advice would be welcome. I already have the first type of regulator pictured above - would I damage the compressor if I fitted this type?

 

[Guest]

i have the one in the second picture, it came with my compressor from everthingairbrush.

i too have no idea what is ment by "bleeding" the air. but these two are not the compressors they pressure regulators and water traps. now i know on the 2nd one there is a little thing on the bottom you press to release the water that collecs and im guessing that is whats at the bottom of your one ( the silver bit ) so maybe it means bleeding the water not the air?

just an idea.

I had a look at the second type of regulator - it's described as a Bleed type regulator:

1/4" BSP Swivel nut air inlet to attach to compressor

1/8" BSP Male outlet to attach suitable airhose

100 PSI (7 BAR) Pressure gauge

50 micron filter to remove particulates and moisture from air supply

One-touch water drain

Bleed type regulator to reduce pressure

I assume it must vent air to stop some kind of back pressure building up against the diaphragm in the compressor or something. I just wondered why it seemed to mention this specifically with the Werther Compressor I purchased - maybe it's just a bit pony - might cause it to overheat or something if the airflow is restricted or something?

I also found this when I was looking for more info online, this compressor has internal bleeding - Can anyone help clarify what all this means? I'm sure it'd pretty much work by just screwing a regulator on the outlet but it's nice to understand why some things work and others work better:

CYCLONE I MODEL 180-1

Portable 1/12 HP oil-less diaphragm type compressor has internal bleed,

allowing use with any make air brush. It is compact, lightweight and quiet

and can be carried form room to room. Maximum running pressure Approx.

28 PSI. (1.93 bar)

Additional Specifications:

Motor: 115 volts, 60 Hz, 2.5 amp

Dimensions: 8 ¼” L X 4 ¾” W X 7” H (21 X 12 X 18 cm)

Shipping Weight: 9 lbs (4.08 kg).

22.5L/min @ 1.38 bar

not sure there sorry, i notice it says 1/8" BSP Male outlet to attach suitable airhose.

i didnt get that info with mine and had no idea what size it was going to be or what size the hose i got with my badger airbrush was so i now have to wait to get some adaptors. but now knowing that its 1/8" helps me alot thanks!!!

and i have lost my adaptor for use with "cans of air" so i cant do any spraying. my bradger is getting lonely.lol

I finally got the compressor in the post (Item Brand new RRP £79.99 purchased on Ebay) unfortunately the seller decided not to put any kind of foam or bubblewrap around a 6.5 kilo cast aluminium and plastic enclosed compressor and the bulk of the thing getting thrown around in transit has smashed the plastic parts to bits! It already had some parts of the enclsure missing too - so there's a nice big capacitor with it's spade terminals all nicely exposed to the air.

Anyhow not to worry about the thing being internal or external bleed now - just send it back so the guy can stick it in the bin!

Feels sad for the compressor - It didn't have much of a life!

1. Buy Compressor
   
2. Lose parts of the enclusure
   
3. Screw Up the Instruction Manual
   
4. Dump the Compressor In Box
   
5. Sell on Ebay
   
6. Recieve Item back in Post
   
7. Throw Compressor in the Bin...

Unfortunately there seems to be far too many sellers on Ebay that see it as a fast way to a fortune. They do not even realise that they are supposed to package these things securely to protect them in transit. I bet you have trouble now getting either a replacement or your money back as he will hide behind the old "I can't be held responsible for the Post Office" crap.

Interestingly enough that seems to be posted on a high percentage of Ebay pages yet if you speak to the Post Office they are quite clear. The responsibility to claim is with the SENDER!!!

When I pointed out that there is no incentive for the sender to be bothered following up a claim once he has the money in his pocket they didn't seem to have an answer for that.

Yet again the customer is left shafted and no-one else gives a dam.

I once received a rare plate in a JIFFY BAG. The postman was quite apologetic when he handed over this sorry bag of chinking peices with the comment "I hope that wasn't valuable"

 

[Guest]

I'm sorry about the rare plate / jigsaw puzzle, I suppose in a way it was an even rarer plate after that!

Message from the seller:

"i can asure you that the item was packed correctly and also complete."

There was a rather optimistic "This way Up" written on the side of the box and a small arrow in felt tip pen.

The compressor was lose inside the box with no bubblewrap / foam etc but it did have four small rubber feet on the bottom, if in transit it was almost loving carried and paying attention to the correct way up, the royal mail vans driven smoothly and with upmost care, especially during cornering I suppose it shouldn't have been damaged...

:spanka:

 

[Guest]

right. finaly i can use my compressor now!

i had to get a new hose with the 1/8" and an adaptor so that could then go onto my badger. been playing with just air this morning and with my regualtor i can get from 10psi to 60psi

so later or tomorrow a model hack comes out and i will have a propper play!!

 

[Guest]

yeah - last time I bought something on ebay it was faulty, took it back (as the seller is 2 miles from here) and he sent the replacement out when he had them in stock. It never arrived and he said "ask the Post Office". Previous occassion the envelope arrived with a hole in the corner where the goods had been removed. At least he replaced it. Before that I was charged £2.99 each for two items that cost me less than 10p each and they came in a brown enveope with a 26p stamp.

hmmm - why did I leave ebay ?

What possessed me to go back?

BUNK - just noticed - you are a rocker! :smile11:

 

[Guest]

there are some good sellers on ebay... honestly there are !

 

[Guest]

I'm not having much luck with this compressor!

The second one I purchased after the first one arrived broken in the post had a small leak from one of the compression fittings where it was threaded into the air receiver.

I decided to put some PTFE threadtape onto the threads and tweak it back up to see if I could get an airtight seal. I put a spanner on the nut and proceeded to try to remove it and it sheared off straightaway. It left the remainder of the thread in there and I couldn't budge the thing with a screw extractor. I've now decided to send the thing back for a refund. The compressor air reciever was also slightly dented from shipping despite the whole thing being surrounded with polystyrene chips.

I bought the thing from Everything Airbrush and they have offered to collect the item and refund the cash, but they haven't collected it yet so I can't comment on their service yet.

Also I noticed some of the rigid pipework between cylinder head and air tank wasn't even pushed into the compression joints correctly. One of the olives was half hanging off the end of the pipe so wasn't really much way it could be airtight anyhow.

I think I'll pay a little more and go for something of a little better quality than cheap unbranded chinese compressors. They look pretty nice in the photos but as is the custom with these kind of things, the materials used are all a little low quality and the machining of the threads leaves a lot to be desired.
