Zero oil emissions
just clear exhaust
The liquid ring vacuum pump creates it’s suction power on water and emits no oil. This, very clean type of operation, makes the liquid ring pump the suitable choice for urban applications and protection of operators’ health.
Compared to a vane pump, the liquid ring pump ensures a clean and safe working environment with a 100% clean exhaust.
Tests of vane pumps show that a 1200 m3/h vane pump will emit several liters of harmful oil into the air during a normal working day. Causing a damaging and unhealthy environment, both for operators and citizens.

Blowers
If gas powered, the blowers will generate emissions simiar to small gas engines.

Vane pumps
The vane pumps emit several liters of harmful oil into the air during a workday.

Liquid ring vacuum pumps
The liquid ring vacuum pumps use only water, so the emissions are clear exhaust.
“Oil and gas emissions are harmful for operators and passersby and ruining surroundings“
The increasing awareness on pollution draws attention. Besides ruining quality of life for operators in hazardous environments, emissions also ruin surroundings. Oil films and stains on roads, pavements and buildings are becoming unacceptable. E.g. in city centers with historical buildings and monuments authorities are regulating equipment not complying with strict measures on emissions. This is also effecting vacuum trucks and there environmental footprint.
