Condensate Treatment for Compressed Air Systems

Oil-injected compressors produce condensate containing water, compressor lubricant and airborne contamination. An oil-water separator treats this waste stream before disposal, helping businesses manage condensate responsibly and meet applicable local requirements.

Choose the Correct Oil Water Separator

Capacity

Total Compressor Airflow

Size from the combined airflow of every compressor discharging into the separator.

Lubricant

Confirm the Oil Type

Mineral, synthetic and polyglycol lubricants can require different treatment media.

Usage

Operating Hours

Longer running hours and high condensate volumes may require additional capacity.

Discharge

Check Local Consent

Confirm the applicable trade-effluent and disposal requirements before discharge.

How an Oil Water Separator Works

Compressor condensate enters the separator and passes through specialised media. The media captures and retains oil while treated water moves through the system to the outlet. The exact process varies by model and lubricant type.

  • Separates compressor lubricant from condensate.
  • Reduces the volume of oily waste requiring specialist disposal.
  • Supports responsible condensate management.
  • Simple installation and routine servicing.
  • Selected Tanair systems offer service life up to approximately 4000 operating hours.
Never discharge untreated oily condensate into surface water, groundwater, storm drains or any location not authorised for the waste stream.

Installation and Maintenance Guidance

  • Connect all relevant condensate drains to the treatment system.
  • Install the separator upright on a stable and accessible surface.
  • Confirm inlet and outlet connections before commissioning.
  • Use the correct media for the compressor lubricant.
  • Inspect outlet quality and use the supplied test method where applicable.
  • Replace service media at the recommended interval or when outlet quality deteriorates.

Oil Water Separator FAQs

Why does compressor condensate need treatment?

Condensate from an oil-injected compressor can contain lubricant and other contamination, so it should not be discharged untreated.

How do I size an oil water separator?

Use the combined airflow of all connected compressors, lubricant type, operating hours, ambient conditions and condensate volume.

Can one separator serve several compressors?

Yes, provided it is sized for the combined airflow and condensate load of every connected compressor.

Does lubricant type matter?

Yes. Some lubricants, including polyglycols and stable emulsions, may need specialist media or a different treatment method.

How often should the separator be serviced?

Follow the model-specific service interval and monitor outlet quality. Selected Tanair systems offer up to approximately 4000 operating hours between media changes.

Can treated water always be discharged to a sewer?

No. Discharge conditions vary. Obtain any required consent and confirm local trade-effluent requirements before disposal.
