How much Oil to use in a Sullair Compressor?
It’s very difficult to determine how much Sullair oil your specific compressor pump requires without having the manual at hand.
If there is no manual available, I advise that you contact Sullair directly or begin an internet search for the specifications of your Sullair compressor and its model to get the exact amount of lubricant you should put into your Sullair compressor.
It’s hard to give you an exact number on how much you need, however, I can give you tips on how to check the Sullair oil amount inside your compressor and then tell you how to go about changing it.
Sullair Oil Sight Glass
Below is an image of a sight glass with the Sullair oil filled to about half way up the red dot inside the glass. They allow you to check the level inside your pump and you should aim for your Sullair oil to be at this level.
Sullair Oil Dipstick
Sometimes, sight glasses may not be present. Instead you can look to use the sump dipstick. These can typically be found as part of the Sullair oil fill tube cap and extend down into the sump and Sullair oil.
To check the Sullair oil level, remove the dip stick and give it a wipe. Then “dip” it back into the sump and when you pull it out again you will be able to know the Sullair oil level from the markings on the stick. This will help you know whether you need to add more oil or not.
Alternative Method for Checking Sullair Oil
An alternative method is draining the oil from the tank if you do not have a sight glass or dipstick.
How to Drain Oil from the Sump
Locate the plug underneath the compressor pump housing that will thread out and allow your Sulair oil to drain. You must be really careful to not drip dirty oil all over everything. Lay out something on the floor beneath the drain, one that won’t be damaged by Sullair oil leaking onto it in the case that you do have a spill.
You can now drain the Sullair oil out into a reservoir that can be used to estimate exactly how much Sullair oil was in your sump. Then you can ensure you put the same amount back in.
How to change Sullair Compressor Oil
Changing Sullair oil on every model of compressor vary. First question whether your compressor is definitely lubricated?
If you are not so sure and you cannot locate your manual, I will recommend navigating to the Sullair website, finding your local outlet using the guide provided, and asking them about your specific model!
Changing Sullair Compressor Oil Process
After draining the Sullair oil from the compressor following those steps just presented, replace the plug at the bottom of the compressor sump and ensure it is securely fastened.
At the top of the Sullair oil sump there should be a port where you can add the new Sullair oil. Due to many varying models of compressors it’s difficult to be more specific than that as they may have different Sullair oil-adding ports.
Please be careful when filling the compressor with Sullair oil to not accidentally put Sullair oil into the air intake port.
After you fit the plug back into the bottom of the sump, add the Sullair compressor oil into the fill port until you’ve added about the same amount as you have removed. Note: You certainly do not want to overfill the sump.
Summary
The above methodology can be simplified into the following steps:
- Check Sullair oil level
- Locate plug beneath sump
- Drain Sullair oil into a reservoir
- Tighten plug back into sump
- Locate Sullair oil port
- Replenish the compressor with the same amount of Sullair oil as removed (do not overfill)
Without access to each Sullair air compressor model manual, and assuming that the manual actually tells the reader what the Sullair oil volume is to be, there is no way to be anything but vague when providing the steps for changing Sullair compressor oil.
Sullair Compressor Oil FAQs (Frequently Asked Questions)
Oil in air filter – setting Sullicon control to inlet valve.
by ty edmaiston
(Lake Charles, LA, United States)
Oil haze is coming back up through air filter during shutdown?
Also how do you set the linkage correctly for the sullicon controller to the air inlet valve?
_________________________________
Sullicon control
These are likely related. The butterfly intake valve is supposed to completely close running unloaded, and gradually opens as demand increases.
The haze probably means the valve isn’t fully closing, which could be either maladjustment of the linkage or the sullicon diaphragm is failing.
__________________________________
Inlet Valve
Hi,
The reason that there is oil mist coming from the air filter is that the inlet valve isn’t sealing properly.
To stop this you need to fit a service kit to it, BUT if you try to do this yourself then you need to be very very careful, the inlet valve has a very strong spring inside it so if you don’t know how to dismantle it properly it can be fatal, so please please get a qualified compressor service engineer to do it.
I don’t know what you mean when you say “setting the linkages” on your compressor? Please could you give a little more information
