Frequently Asked Questions

Is the 300EBM303 float gauge compatible with my Gardner Denver compressor?

The 300EBM303 is a Gardner Denver float-type oil level gauge used in compatible Gardner Denver compressor oil reservoir assemblies. Compatibility should always be confirmed by matching 300EBM303 in your compressor parts manual and verifying the model, serial number, oil reservoir configuration, gauge mounting location, adapter arrangement, and installed part number before ordering. Not sure? Reach out with your compressor model and serial number and we’ll help confirm compatibility. 

What does the 300EBM303 float gauge do?

The 300EBM303 provides a way to monitor the lubricant level inside the compressor oil reservoir.

Its float mechanism responds to the oil level in the reservoir and provides an external indication that helps operators determine whether the lubricant level is within the proper operating range.

The gauge helps:

  • Monitor compressor lubricant level
  • Identify an underfilled oil reservoir
  • Identify an excessively high oil level
  • Support routine compressor inspections
  • Help prevent operation with insufficient lubricant
  • Maintain proper compressor lubrication

Why is the 300EBM303 float gauge important?

Maintaining the correct compressor oil level is important for reliable operation.

A functioning 300EBM303 helps operators identify lubricant-level problems before they contribute to:

  • Insufficient lubrication
  • Elevated compressor temperature
  • Accelerated component wear
  • Excessive oil carryover from overfilling
  • Compressor alarms or shutdowns
  • Premature air end or bearing damage

The gauge makes routine oil-level inspection easier without requiring the reservoir to be opened.

What are the signs that the 300EBM303 float gauge needs replacement?

Common signs include:

  • Gauge remains at one level regardless of actual oil level
  • Indicator sticks or moves inconsistently
  • Float no longer moves freely
  • Gauge face or housing is damaged
  • Oil leaks around the gauge connection
  • Indicator reading does not match the actual reservoir level
  • Gauge becomes difficult to read
  • Internal mechanism is contaminated or damaged
  • Gauge fitting or mounting point is broken

Before replacing the gauge, confirm that the compressor is on a level surface and that the lubricant level is being checked according to the manufacturer's procedure.

Is this an OEM part?

This is an OEM-equivalent replacement float gauge designed to meet the same performance standards as the original Gardner Denver float gauge.  

How difficult is it to install?

Replacing the 300EBM303 is generally a moderate compressor maintenance task because the gauge connects directly to the oil reservoir.

Before service, the compressor should be:

  • Fully shut down
  • Electrically locked out
  • Completely depressurized
  • Cooled to a safe working temperature
  • Verified so it cannot automatically restart

Installation generally involves accessing the oil reservoir, removing the existing gauge, inspecting the gauge adapter and sealing surface, replacing the applicable gasket or seal, installing the replacement 300EBM303, and checking for oil leakage.

After installation, verify that the gauge moves freely and provides a reasonable oil-level indication.

Do you carry other parts for Gardner Denver?

Absolutely. We stock a range of air filters, oil filters, separators, synthetic oils, and many other maintenance parts for Gardner Denver equipment. If you don’t see what you need, just ask and we’ll help you find it.
