Does anyone have experience of the recent models of SIP compressors
available from costco (or anywhere else for that matter) the one I am
hoping for comment on is the T3/150 SRB which is 3hp 150L belt
driven(i think). Good or bad - any comments - especially regarding
noise level and reliability/ build quality.

Many thanks

Yes. I have the SIP model up from this one - the P3/150. They are
essentially similar except that the P3 has cast iron cylinders and
slightly higher output. I don't think the T3 (aluminium cylinders)
was out at the time.

I use it in my workshop where it is about to be hooked into a
distribution system. It covers all of my needs including air hungry
tools and sprayers with continuous running (or continuous as I need).

I had a small SIP one before and found it pretty good, so when I
needed something larger, went for this one.

The product is well made in Italy and has been completely reliable.

It comes with three wheels - one being a castor - so can be moved
around reasonably easily. The P3 is 77kg, but can still be moved
around flat surfaces - the T3 is 55kg so a bit easier.

There is a regulator with two PCL connectors and at the other end an
unregulated output with valve.

Even doing nothing, the noise is not objectionable - it is at a much
lower frequency range than the smaller machines so is more of a
thudding sound. With the compressor just sitting in the garage and
running with the doors closed, the noise is not very noticable 20m
away - about like a car engine idling at similar distance.

I've put my compressor up at ceiling height - i.e. in the roof space
and instead of using the wheels made two stout wooden frames fitted
together with four antivibration mounts (RS do them). The compressor
is bolted to that and it sits on the boards. With the trap door
closed, the noise is very low and one can comfortably have a
conversation in the workshop below at normal voice levels.


What are Costco doing it for? There may be even better prices
elsewhere....
