Industrial compressor that start with G m ade in Germany screw oil filters

[RANGER1]

Are G_ _ _ _ _ crazy or what.

The oil filters are cleanable, with difficulty, but also manual recommends somewhere to throw tham away after 5 or so goes at cleaning them.
A new filter is in round figures $900.
The filters are a different size on each compressor size , so you can't even have a common spare if you have a variety.
I think they lost common sense on this one!
Rationalization would cost them & everyone less money & inconvenience.
To isolate filter you have to close oil injection valve, which someone set at commissioning.
Maybe its set right after first filter change!

Another good one is PTFE dowel pins which do nothing, after using expansion hydraulic dowel.

You give them to much oil pressure & they drive into end housing.
No wonder they have replacable discharge end plates.

The Australian version uses a Viking oil pump with oil filter on suction of pump, nothing on discharge.
Sounds like another accident waiting to happen.

Hi Ranger.
You seem to have a few issues there my friend?
Sorry to be thick but are you talking about Grasso compressors? (Made in Holland?)
Are talking about RC12?

They have a paper element Filter (obtainable through Motor factor dealerships for a fraction of the price)

The Gauze Strainers can be cleaned using a ultrasonic bath, the kind Fuel Injection specialists use to clean injectors.
Who will clean them for a small fee
Of course I could be talking Cr*p.
Could you enlighten?
Cheers Grizzly

Grizzly,
Sorry I'm talking screw compressors & thought they are made in Germany.
As for the cleaning of the oil filters, understand about the ultrasonic cleaning, but its not very convenient & more expense time wise. Get the bulk of oil off, delivery, pickup etc 7 you still have to buy 2 spares in my case as have 2 different size compressors.
It seems Euorpean manufacturers like to have oil filters at ridiculous prices, so you are not encouraged to change them because of price.
Example Frick disposable oil filter $50 Sab screw disposable $500 Other $900.
You would'nt want an oil filter issue, as it would sent you broke.

We also had a Bitzer the other week, sorry no oil filters in Australia, they are on order.
We fixed & choped it out & put in local proven filter/housing.


Maybe its just Australian issue.

[Grizzly]

No Problem.
You may well be correct about the screw comps being German.

You show lots of initiative there by substituting the filters and given what you guys are paying I don't blame you.
Probably 10-15 yrs ago I discovered that the Grasso recip paper filters were re badged Crossland
at 10's of pounds each.
Or approx £30 or so for a box of 12 from a motor factors shop.

A filter is a filter, provided you can replicate the filtration density why not source locally.

As Frick and Sabroe are one and the same nowadays, I an surprised at the price difference.

Hey if worried (about using alternatives) increase the frequency of the oil and filter changes.

In fairness though, It's all well and good me advocating alternatives.

I am not the one maintaining these Comps. I am less cautious when dealing with an older comp.
But I generally would stay within the manufacturers guidelines with a newer comp.
Good luck in your quest.

Hi. Oil filter Frick $ 50? acceptable even for Europeans, but the reality is different, you're right Ranger1, the problem of many species and a lot of money.Grizzly course confirms the right price difference from parts of JCI Denmark and France.
And European resolves as you Ranger1.

May well turn out to be a useful post for some?
thanks.

good day , grizzly. saw the post on g--- comps, which turned out to be grasso . we have 2 grasso recips, an rc411, and an rc 612. for the rc 411, the paper filter, i was able to buy a substitute , a german brand filter (kengst or hengst, i think). however for the suction filter of the of the rc411 and the 2 filters of the rc 612, i resort to re filling of the element by a local oil filter store. i have been doing this for almost 3 years, and i think it fairly works. the few times a grasso technician visits us (the technical people anr different from the sales ), the technician always say that the oil quality inside the compressor is still good. of course, i haved the change oil interval , but it still comes cheaper than buying all oe filters. anyway, if the oe filters of grasso are expensive, the cost of sabroe oil filters, here , is way , way , way expensive. can i ask what was the alternate part of oil filter for the grasso you were mentioning ? what about for the sabroe smc 112L model ? do you have knowledge of the counterpart filter ? the cost of sabroe parts are really something. thanks

We can get any filter made of copied, but don't see why we should have to.
The Frick genuine filter 5 micron is a very good price, which can't be made any cheaper.
In Australia the common filter which a lot of people use is called a C709 filter, which I think was copied
from something fron th USA 30 yrs ago.
Mycom do the similar to Grasso on their packages in Australia, by installing their own cleanable design.


I just don't like the cleanable ones as it a pain when their is a number of them.


Clients with Sabroe screws would only use synthetic oil from day 1 as it behaves well by not breaking down like mineral oil.

[RANGER1]

Grizzly,
Out of interest i think the Frick/Sabroe filter is for Europe only.
The genuine USA ones are different & basically same as the filter we use ,but ours with 25 micron not 5 micron as Frick use

Hi Ranger1,
totally agree with the rediculous pricing on euro sourced compressors, screws and recips., oil filters. I use alot of those C709 filters, found an importer that sells them for $55.00 and he is make money on them. Plus he does the Bitzer screw filters as well [mahle] for a fraction of the price, and the sab filters and SMC internal paper filters.

[RANGER1]

Magoo,
I was hoping someone would bite on the Grasso screw critisism.
Give it time I suppose.

It can be a help.
