Ready for Dusty Venues
1
IP6X Sealed Engine Design for Dust-Prone Environments
Shields the projector’s optical engine from dust intrusion, ensuring long-term stability and reliable performance in harsh, dust-prone environments such as exhibition halls, factory spaces, and training centers.
2
Optional Filter for Extra Protection
Provides added protection in dusty environments and helps extend projector life.
3
Auto Reset Mechanism with Built-in Timer
Automatically tracks filter usage and resets the timer when a new filter is installed, without any manual setup.
IT takes control
Streamlined Device Management
Remote Monitoring and Diagnostics
Easily track projector status and diagnose issues remotely, eliminating frequent on-site visits.
Firmware Management Over Network
Easily update all projectors via LAN to keep firmware current without physical access.
Reliable Performance, Less Maintenance
Ensure long-term stability, freeing SI teams to focus on creative installations rather than routine upkeep.
