Secure operational efficiency with a proactive obsolescence solution. Replace phased-out MICROMASTER ventilation inverters with SINAMICS VFDs (Variable Frequency Driven) to keep your dryer fans running.

Stay Ahead of Obsolescence

In highly automated production environments, a single obsolete component can stop your entire line. MICROMASTER ventilation inverters were phased out in 2017, yet many rotogravure presses from 1997-2012 still rely on them.

Failure of a ventilation drive results in immediate machine downtime. The MICROMASTER Ventilation Inverter upgrade replaces outdated drives with the latest SINAMICS VFD technology, fully integrated into your PLC, while maintaining existing automation controls.

Why This Upgrade Matters

Keep Production Running

Minimize unexpected downtime by replacing obsolete ventilation inverters before failures occur, ensuring every shift operates without interruptions.

Avoid Costly Disruptions

Prevent expensive emergency repairs and lost output by proactively upgrading critical components.

Spare Parts on Standby

Modern SINAMICS VFD drives maintain optimal performance, extending the useful life of your rotogravure presses.

Strengthen Operational Resilience

Build a more reliable production environment with proactive obsolescence planning, supported by BOBST Connect for remote assistance and monitoring.
