Does this screen require a lot of maintenance?

The Ovivo Duet dual aperture screen is very easy to maintain. The screen was designed for a long life, with only a few wearable parts. Occasional replacement of the second stage mesh, rollers and spray nozzles should be expected and the drive bearings require grease periodically. Seals, motors, the washwater solenoid and the drive pinion should require minimal service. Ovivo service contracts are also available.
