Features:

  • Comprehensive Front-and-Rear Slot Sealing – Protects empty module positions from dust, debris, and accidental contact.
  • Airflow Optimization and Thermal Management – Ensures proper cooling over active modules while maintaining safe temperature ranges.
  • Industrial Safety and Structural Integrity – Shields backplane connectors and preserves the mechanical strength and professional look of the rack.
The Bently Nevada 128275-01 Full-height Front Panel and 128031-01 Rear Cover offer a robust solution for empty module slots in 3500 Mechanical Protection System racks. By sealing both front and rear positions, these components protect sensitive backplane connections, optimize cooling airflow, and maintain safety standards, even in harsh industrial environments.

In practice, the 128275-01 ensures airflow is properly directed over active modules, preventing overheating and maintaining system reliability. At the same time, the 128031-01 provides isolation from live electrical contacts and shields the rear from contaminants such as oil, moisture, and dust, which are common in industrial settings.

Together, these panels enhance operational safety, preserve reserved module space for future upgrades, and maintain the professional appearance of the 3500 rack. The Bently Nevada 128275-01 and 128031-01 combination ensures that partially populated racks remain fully functional, safe, and ready for future monitoring expansions.

The 128275-01 128031-01 Bently Nevada Front & Rear Blanking Plates may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The Bently Nevada 128275-01 and 128031-01 are designed as paired blanking plates to maintain the operational integrity of the 3500 Mechanical Protection System. Together, they form a practical solution for racks where monitoring modules are not yet installed, providing airflow control, backplane protection, and a professional appearance.

The 128275-01 Front Panel mounts directly into the full-height front slots of the 3500 rack. Its primary function is to seal empty module positions, guiding cooling airflow across installed active modules and preventing system overheating. By blocking dust and debris, the front panel also protects sensitive backplane connectors and preserves the reserved space for future monitoring modules, such as vibration or displacement sensors.

Complementing the front panel, the 128031-01 Rear Cover attaches to the rear I/O module area. This cover ensures safety by isolating unused backplane contacts, preventing accidental electrical contact during maintenance. It also protects the rack’s rear connections from industrial contaminant128275-01 128031-01s, including oil, moisture, and conductive dust, while maintaining structural stability and professional appearance.

Both components are rated for demanding environments. The 128275-01 operates from -40°C to +85°C, while the 128031-01 handles -40°C to +70°C. Both tolerate 5%–95% relative humidity (non-condensing), ensuring reliability across a wide range of industrial conditions. Installation is simple, using included mounting screws to secure the panels into the rack’s respective slots.This kit simplifies future expansion, allowing operators to add monitoring modules without compromising airflow, safety, or cleanliness.
