hi all, i have been given a compressor, which needs a bit of work doing to it. But before i do anything i want to know if i can run it off mains power supply and if not will it cost much to convert etc... I think its a clarke air 150 litre belt driven compressor, the tag off the motor reads-

CLARKE MOTOR
TYPE:90LB/2 HP:3.0 RPM:2700 NO:70214423 KW:2.2 PH:1 V:230 HZ:50 A:14.5
CAPACITOR DETAILS
UF?:60 V:450 MF:


Sorry if this doesnt help, if you need anymore info let me know. thanks

It has a 3 pin plug on I assume.I'm not even sure that Clarke even do 3phase equipment come to that. The details above are fine for domestic single phase power.At 3 hp it suggests a fairly good compressor with possibly up to 12 cfm output which is enough for air tool use and plenty for a blow gun and tyre inflating.

yes, 3 pin plug, although it looks as if it has been re wired at the capacitor, see pic. There are 4 pins off the capacitor, only 3 being used, is this right? sorry about picture quality

It's stated at 14.5 amps, so not really made for a 3 pin plug of 13 amps. The compressor would have been shipped without a plug on the end just a wire tail to be wired into a isolator with say a 16 amp breaker supplying it for protection. A mate of mine use to have one with a plug wired on the end, would always blow a 13 amp fuse now and again. This has now been wired up on its own circuit now. Also have heard stories of people buying one on eBay and when checking the fuse found 6mm cut down bolt in the fuse holder!? Hope this helps, Dan

As said,I think you'll struggle to run that off a domestic plug. I had a similar sized machine given to me last year, I tried to use a domestic 13a plug and supply but it blew the fuse instantly . I have now wired it into it's own dedicated supply back to a 32a breaker at the fuse board, also used a a 16a round pin plug & socket,http://www.toolstation.com/shop/p36175 ,http://www.toolstation.com/shop/p20698

no problems so far

sorry for late reply.. been very busy going in and out of hospital. I'm going to wire the compressor up on its own circuit, but before i do that was just wondering if anyone has a compressor like this and could point out what parts i need... I know i need a new pressure guage, and i presume that i need a valve of some sort to connect to the end of the compressor (see pic) would i need another guage there?... if anyone wants anymore pictures just let me know. thanks

it will work without the gauge but its obviously better to have one... no you dont need a gauge at the outlet and you can fit a valve or just fit your pipe fitting straight on but i would personally fit a valve. you may also want to get a regular as that machine most likely will cut out around 10 bar and a lot of air tools are rated to 6 bar.

[tommo10]

im guessing you mean regulator? how do you connect one and where?

[mike174]

yeah sorry was a typo i ment regulator they connect inline on the outlet of the compressor is ususlly easiest or anywhere in between the reciever and the tool you are using

[tommo10]

Cheers mate, do you recommend anywhere to get these parts, thanks

[mike174]

erm not sure for retail to be honest ebay machine mart etc etc should be ok but others may be able to advise better.
