Does the GTX have a vacuum pump?
No. The design of the vacuum chamber (where the flywheel rotates) is factory sealed. At the top of the rotating group shaft is a maintenance-free patented molecular vacuum sleeve that maintains a near-total vacuum, a pressure level nearly a million times lower than atmospheric pressure. This eliminates aerodynamic drag for maximum energy efficiency. The sleeve discharge is stored in absorbers located in an attached evacuated housing. This configuration eliminates the need for the mechanical vacuum pumps used on other flywheels that require electric power as well as maintenance every 6-12 months and costly replacement every 3-4 years.
