Oil Separators
Petrol separators – Compact and inexpensive to maintain

ACO has completely upgraded its light-oil separators in response to the new European standard EN 858. This product line now sets new benchmarks for separator technology.

Inflammable or explosive atmospheres can build up in the wastewater piping systems of petrol stations, car washes and vehicle workshops. These hazardous atmospheres must be isolated by separator systems. ACO has three solutions available with the ACO Passavant light-oil separators OLEOMAX®, OLEOSAFE® and OLEOPASS®, which all comply with EN 858 and German DIN 1999-100.

All light-oil separators built by ACO are class I separators (certified with 5 mg per litre residual hydrocarbons). After removal of the coalescence element, they naturally also comply with all specifications for class II separators (certified for 100 mg per litre residual hydrocarbons).


The universal separator complying with the latest standards
