Compressor advice

[Neale]

I want to have a play with a fridge compressor, (If I can get one for free out of a de-gassed fridge) I have no idea what the output is like, but at least they are quiet.

Interesting idea - might have one to play with myself next week once guy has been to change compressor in our fridge/freezer. Mind you, the fact that it needs changing probably means that it might not be in great nick... However, I did discover that the current refrigerant gases in use can be released into the atmosphere so degassing might not be a big deal if you can salvage a more recent fridge.

If you can wait a bit, I would suggest keeping an eye open for the ALDI compressors. They are probably the best value for money and they come with a warranty that will be honoured if it fails.

I bought a 2nd hand silent compressor, something around 25-30l and would caution that they take a while to reach pressure and can't easily sustain any decent flow for any length of time. As someone that gets irritated by noise easily, the silent compressor is great, but limited. I'm almost tempted to add a large receiver external to the shed and let it charge over time, but that's a job for another day.

I bought a Bambi silent compressor 6 years ago for £300. Permanently switched in the front room I top up the oil once a year, probably time I bled the tank or something but it is so easy to forget it is there.

if you are a DIY person- Junkyard. 1hp or bigger compressor from air conditioner , 5-7euro where i live. make sure to obtain the capacitor and power cable, as later will spend more time in internet searching how to wire it. Silent and powerful. Small. But heavy. No need for additional air tank.Check oil and pour inside if necessary. Whatever oil you have/machine, car, not frying oil/. Plug a car fuel filter one side so no dust enters it, and hose at the other side. Thats it. It could be used for mist cooling, painting with small gun, etc. Even for vacuum holding, i would say-especially for vacuum holding.

Or cheap 2HP, ~70EUR or GBP will do. Any mega store.


From there to a professional compressor its worth buying one 2hp more , than buying compressors in the 70-800EUR range. I am talking Spain, but in UK should be similar.
