Bambi 75/250 is not building pressure

This Bambi has been working for over 20 years, but has stopped building pressure

Any suggestions appreciated

Well, the first suggestion is to visit the sitemap page, and look under the troubleshooting section. Follow the links to pages that talk about why air compressors run but don't build pressure.

When you understand a bit more about why they don't build pressure, and do some of the checks, then post a comment here with your findings, and we'll see if we can help further.

Smoke from inlet
by: Anonymous

Compressor not building up enough pressure and smoke from inlet. Can someone help me out here.
__________________
Smoke from inlet suggests two things. 1) Your Bambi air compressor may be low on oil, assuming your model is oil lubed and 2) air / smoke coming out of the air intake suggests that the intake valve is worn or broken.

If the valve is failing, then it is time to teardown the pump and replace the valve(s). At the same time, replace any gaskets that are present.

Hi im having a problem with air shooting , i can hear the air is running out from on of the engines. Sometimes one of the engines is turning off. What can be a problem ?

thanks for help

Hi there Marta.

By the time I make the photo large enough to see, it's all blurry, so I cannot find on this compressor where the unloader valve might be.

Please read the pages on the unloader valve and on the tank check valve. Also, see the troubleshooting section on the sitemap page for links to pages about these items.

Though your post isn't perfectly clear to me, I suspect that either of these may be the issue you are facing with your Bambi air compressor.

Bambi 75/150 has slight oil leak, not sure where to start!

by Simon
(Birmingham, UK)

Bill, I have a 2nd hand compressor which has a slight oil-leak.

I'm a complete novice so I'm not sure where/what I should be checking to identify and correct the problem. Since I bought it about 8 months ago the oil level has very slowly gone down.

The compressor is a Bambi 75/150.

Obviously I know you are unlikely to be able to diagnose the problem from this information. I was just hoping you might be able to suggest a few parts that are more likely to be responsible that I should check first. I have the manual from the Bambi website.

Thanks!

Hello Simon.

Well, Bambi appears to be a good make of compressor, but seals do go, bolts do loosen, and, sometimes, tracking a leak may be more trouble than it's worth. The leak will be dripping slowly from the pump down onto the tank, I would expect?

It's not an elegant solution, but when my small workshop compressor developed a small, wicking-type leak like yours sounds like, I simply folded a shop rag and inserted it where I thought the leak occurred - between the base of the pump and the tank - (after checking bolt tightness, of course) and that rag catches any drips before they flow down the tank to the floor.

Monitoring the oil level is critical, however, if the leak is a minor as you suggest, chasing it down (beside the obvious checks) may be more trouble than it's worth. And if it is a seal, is it worth the cost of tearing down the pump, replacing all new gaskets... etc., etc?

It's your call, of course.

Cheers,

Bill

bambi bb24 compressor: what does small and big dial show?

by burki
(newcastle upon tyne)

hi i ve a bambi compressor im using for dental purposes,now it gets heated up and stops, i need to know what does the big dial and small dial represents and how cut off pressure can be adjusted?thanks
_____________________
Well Burki, the bigger gauge near the bottom indicates the tank pressure, and the smaller gauge on the top, just below the handle of the regulator, shows the pressure setting of the air that will flow down to your dental tools.

If your compressor is heating up to the point where it overheats and the motor kicks off on thermal cut out, I suspect that it may only be that you are using more compressed air than the air compressor can generate. Overheating is often a result of exceeding the air compressor duty cycle.

The output of this air compressor is:

Output 50 litres/min (1.75 cfm)

If your demand for air is greater than that, you may be overtaxing your compressor.
