This system eliminates the use of a vacuum pump, thereby avoiding frequent and costly maintenance to system and minimizing spare parts, or even the use of a diaphragm pump, which often gets clogged by waste.

The unit, which is available either truck, or Skid Mounted, consists of stainless steel pumps and de-germ “Fill & Stop” system, and could reduce your lavatory service time by approximately 50%. It could also eliminate clogging in the aircraft that would cause delays or ground your airplane.

The ACCESSAIR vacuum lavatory system can be operated in manual or automatic mode whereby the operator will pre-select the quantity of water or de-germ to the rinse and charge system. The system will automatically pause between each step for operator to confirm and acknowledge that the step is completed (for the rinse, waste vacuum and recharge).

A “fully automated” (same write-up to link to (E) in general lavatory system) system is also available which calculations the requirements by simply selecting the type of aircraft being serviced.
 

• Cost-effective vacuum system with high efficiencies (up to 29.5” Hg)
• ACCESSAIR’s Vacuum Lavatory is the only system that uses the principle of an Eductor (a piece of pipe with no moving parts) to create vacuum in the waste tank instead of a conventional vacuum pump. This ensures long life & low maintenance costs
• This system was developed with the collaboration of INOX-TECH, which is a leader in the design, engineering, and manufacturing of customized stainless steel equipment, tanks and pressure vessels, high performance bioreactors, and process and fermentation systems.
• ACCESSAIR tanks are fabricated with ¼” thick stainless steel with rounded corners and built to 15 psi and full vacuum rating for full protection against collapse.
• Our vacuum system is of a one- (1) step system which maintains a constant and stable vacuum pressure. Once you select the quantity of de-germ for rinse, you press the start button and the unit will vacuum and then send de-germ to the aircraft lavatory unit.
• The fact that the pump has no contact with waste materials, eliminates clogging as found in typical diaphragm vacuum pumps
• Waste passes through a hose only, and not through a pump
• System eliminates waste tank odors by filtering waste gases (air) through the water tank
• Low noise levels
• Intrinsically safe operation
