EMSE lubricated rotary vane systems are very reliable and easy to maintain. The oil lubricated vacuum pumps successfully operate in thousands of installations.

Advantages:	Disadvantages
Long vane life Low maintenance Low noise level Air cooled design No rust and scale problems No water and sewage costs Low operating costs	Unsuitable for a dedicated anesthesia evacuation system Can not take a slug of water

EMSE oil-less rotary vane designs are similar to the lubricated rotary vane pumps, except they are equipped with self-lubricated carbon vanes and do not require any oil for operation.

Advantages:

Disadvantages

Suitable for a dedicated anesthesia evacuation system
Air cooled design
No water and sewage costs

Can not take a slug of water
Much shorter vane life compared with the lubricated pump vanes
Lower capacity per horsepower when compared with the other designs

EMSE water-less (oil sealed) liquid ring system utilizes design features of both liquid ring and rotary vane vacuum pumps. The heart of the system is a liquid ring vacuum pump which can take a slug of water without damage. They are free of vibration and run very quiet. The pump system requires no water. It is completely air cooled. There is no need to be concerned with the sometimes substandard water quality causing corrosion of the vacuum pump internals. There are no water and sewerage costs as well as no requirements for chilled water. Best of all, because it is a liquid ring pump, it is virtually maintenance free. Oil and filter changes are required only after 2 years. In fact, these pumps are provided with a five year warranty.

Advantages:

Disadvantages

Simple, time-proven design
Capable of taking slugs of water
Air cooled
No rust and scale problems
Low maintenance
No water and sewage costs
Low operating costs
5 year warranty

Unsuitable for a dedicated anesthesia evacuation system
Lower capacity per horsepower when compared with the lubricated rotary vane pumps

"Economizer V" water-sealed liquid ring systems with field adjustable water recirculation.

Water-sealed liquid ring vacuum pump systems have always enjoyed a good reputation based on exceptional reliability, low maintenance and a very long field-proven record. However, they normally require a continuous supply of water when they run which can be costly when water and sewage costs are added.

EMSE Corporation has developed "Economizer V" - a line of water-sealed liquid ring vacuum systems that offer a unique feature: field selectable and adjustable amount of partial water recirculation up to 95% without the use of heat exchangers and chilled water. This feature will dramatically minimize operating expenses without the added cost to the initial price, installation and maintenance.

Advantages:	Disadvantages
Very good choice for a dedicated anesthesia evacuation system Simple, time-proven design Capable of taking slugs of water Low maintenance Low operating costs	Dependence on a reliable supply of water Good water quality is critical to avoid premature failures due to scale build-up

High efficiency Dry Claw vacuum systems

High efficiency dry claw vacuum systems are the most power efficient systems available today with the lowest possible maintenance.

Advantages:	Disadvantages
Very good choice for a dedicated anesthesia evacuation system Lowest maintenance Lowest operating costs	Higher noise level then most systems More expensive than most systems
