    I have the L65 Airteck and love it I leave it outside in the cold and it runs just fine at start up. Just change the oil regularly.

S.S.S is your gsv 60 3 phase? It seems that anything over 2 HP is 3 phase on that website, maybe that's standard? I don't know.
    Yes it’s 3phase and I called my local rep last week Friday for current price on a gvs60 for my neighbor and can get one for $2578. And current price on gvs100 is $3517.

    Not sure if this answers your question, but the Atlas Copco pumps do need to be in a heated space and kept warm in order to start up. Oil needs to be warm enough, I believe. We like the pumps. Have 2 and they work good. Just need to design the releaser/pump setup the right way to ensure sap never gets in your pump.

The prices are a little closer as well where as with other Busch pumps that cost quite a bit more. So who has a Busch R5?
    The Busch and airtech pumps are identical, take all same filters oil etc. Rock solid pumps, I've always been a fan of vane pumps as they are more reliable. I do believe that airtech for whatever reason pulls more vaccum, 28.5-29. versus my Busch I get only 27-28........they are the only style pump I would use

    I had a Busch Vane pump and I hated it. It was a 5hp but not sure of the model. It had a LoveJoy coupler that kept shredding and they are a pain to replace if your alone. Air tech does not have that problem. I am running a 5hp Air Tech vane pump in my lower woods and it is a great pump. I just bought a Air Tech liquid ring pump for my sugar house and that works great. The beauty of the liquid ring pump is sap/water can get into the pump and at worst you would just have to replace the oil. That is a 5 minute fix. If sap/water gets into your vane pump you have problems and could loose a days worth of sap. I have a thermostat on my liquid ring pump and I have not drained any moisture from that pump yet. It's been running for 4 weeks now.

    This is my fifth season using a Bush R-5-100 62 CFM pump. Cost 5 years ago, $4575.00. The R5 should be in a heated space that is about 45 -50 degrees. Now for the review.

    The pump makes great reliable vacuum with one warning, which I did not get when I bought the pump. This pump should not be run below 22-23 inches of vacuum or it will blow the oil out the exhaust. I found this out the hard way when pulling taps 2 years ago and letting the drops hang instead of putting the drop on the tee plug. I am lucky that a friend stopped by the sap shed as I was pulling taps and saw the oil blowing out the exhaust. The solution was easy, plug the drops off.

    I have run the pump for several season without adding a drop of oil to the reservoir.

    Like Spud, I don't like the Lovejoy fitting. I have had to replace it twice and it is a big pain.

    The 2 filters for the R-5 are expensive and the oil is expensive if you buy it from Lapierre. $30. a quart. I finally found a source for the Busch oil at $19.00 a gallon.

    If I knew then what I know now, I would buy another brand pump or a different pump. I should have stuck with buying a 2 stage Sihi liquid ring oil pump like what I have at my sugar house. But now I have too much invested in the R-5 to get rid of it and I just run the pump making sure the vacuum level doesn't go below 22 - 23 inches. My vacuum room is heated any way because of the electric releaser.

    Do you mind telling the source for the oil?

    Wiam,

    I bought the gallons of Busch vacuum oil from New Boston Pump in New Hampshire. I think that they are the regional distributor for Busch. I usually speak to Richard. The number is 603-894-6677

    It costs me $27.00 to ship 2 gallons. I got the oil the next day. Even with the shipping, the oil cost a little over $8.50 a quart.
