P38A Dunlop EAS Compressor ANR 3731-SLP

Just as an FYI....

I have just bought one of these from Island 4x4 for £150.00 plus VAT. A considerable saving over the list price of the Land Rover ANR 3731.


Rimmers do them for £165 + VAT. Craddocks £200 + VAT.

Anyway, it arrived just now, and look what I got... First up a Eurospares box, albeit with dunlop branded sticky tape.












A legit Dunlop compressor, manufactured less than 2 years ago. Nice work Island 4x4. I was a little worried, their website doesn't show a Dunlop compressor, and the price seemed very good, but there we are. Sometimes you can't trust a book by it's dust jacket.

A good price, I have a couple of rebuilt ones but I may invest in a new one soon!

I bought the kit to rebuild my old one.... installed it all, but it's worse than it was!

Can't work out what I did, followed the X8R video to the letter, but I've clearly done something wrong. I suspect's it's something to do with the reed valves.

I ended up thinking fcuk it! I'm buying a good one, and I can fix the old one at my leisure.

Also have a Dunlop air compressor on my D3 , slightly different but very pleased With it

indeed a great price

as a side note don’t know if there similar but got rid of all the Voss connectors and replaced them with brass pushfits , was shocked to see those Voss connectors are around £16.00 each whereas the brass pushfits are only around £4.50

in the past have seen some use the cheap plastic collar pushfits that fail, mainly due to them only rated at 10 x bar and compressor has an average output of up to 17 x bar, brass pushfits are rated at 80 x bar

also noticed many online shops that sell the plastic airline pipe also have a low pressure rating , again around 10 x bar leading to a failure point

hope all goes well when u get round fitting it

@MrGorsky If you're gonna be near Langley any time, bring the compressor & an X8R kit, and I can help you rebuild & test it on the bench.

That is indeed a good price, only a fiver more than I paid for the same one back in 2011!

I Succumbed and bought a new one! So I currently have 2 rebuilt, 1 on the car, 1 on the bench and now a new one on the way. I have a brand new driver pack, new height sensors (Dunlop) and a fully tested valve block. As soon as it gets warm again I am going to be tinkering again even though the EAS is currently working! I think that by putting in all of this new stuff and calibrating I shall be good for a while. It also gives me some more bits to rebuild

I'm fighting the temptation to take this new one apart so I'm better skilled to rebuild my old ones.....

I have history doing that though, and may end up with one more broken one! I might do a live trace with the Nanocom once fitted, and stick it on here, just so we know how long a brand new compressor should run whilst driving around!

Personally I wouldn't, you will void the warranty for one and as you say, things may go wrong as per Murphy's first law of P38 tinkering

All fitted. Shot up like one of them lowriders.
