Tip: Start with the installation position (wall / roof / 19" rack), then size by air throughput and confirm options like EC technology and EMC shielding.
Filter fans, roof-mounted fans, and rack-mounted fans
Rittal enclosure ventilation
Rittal filter fans and roof-mounted fans support efficient cooling of enclosures, while rack-mounted fans are designed for installation in the 19" level in IT racks.
Depending on the series, solutions are available with EC technology for increased efficiency and IoT capability, and can also be specified with EMC shielding for sensitive environments.
What special features are available?
Choose ventilation solutions that match your enclosure layout, efficiency targets, and electrical/EMC requirements.
Configuration highlights
- Wall-mounted filter fans for targeted enclosure ventilation
- Roof-mounted fans to support vertical airflow concepts
- Rack-mounted fans for the 19" level in IT infrastructure
- Optional EMC shielding for demanding applications
- EC technology variants for improved efficiency and controllability
- Options designed to support IoT capability (series-dependent)
Good practice for selection
- Define installation position: wall / roof / rack
- Estimate heat load and required airflow (m³/h)
- Confirm filtration needs and maintenance intervals
- Check EMC requirements and approvals for the site
- Standardize on a platform for spares and service efficiency
Note: Fan-and-filter solutions are most effective when air paths are planned (inlet/outlet placement) and filters are maintained to preserve airflow over time.

Where are these fans used?
Rittal ventilation solutions are used to reduce hot spots and support reliable operation in industrial enclosures and IT infrastructure—especially where a cost-effective airflow solution is preferred over active cooling.
Typical applications
- Control cabinets in production and automation
- Electrical enclosures in workshops and utilities rooms
- Packaging lines and material handling systems
- IT racks requiring airflow support at the 19" level
Why teams standardize on Rittal ventilation
- Simple integration with wall / roof / rack mounting concepts
- Efficiency options via EC technology (series-dependent)
- Compatibility with EMC shielding requirements (where needed)
- Maintainability through planned filter and service access
Short definition: Filter fans and roof-mounted fans provide ventilation by moving ambient air through the enclosure (often with filtration), while rack-mounted fans support airflow within 19" IT rack levels.
FAQ: Filter fans, roof-mounted fans, and rack-mounted fans
Clear answers that help teams choose the right mounting concept and feature set.
Choose a filter fan when wall mounting fits your layout and you want filtered airflow through a defined inlet/outlet path. Choose a roof-mounted fan when your enclosure concept benefits from top mounting (e.g., limited side space or a roof-based airflow path). Always confirm sealing, maintenance access, and required airflow.
EC technology (electronically commutated) supports efficient fan operation and enables controllable speed—useful for demand-based ventilation, energy reduction, and better temperature management (series-dependent).
Specify EMC shielding when your application requires reduced electromagnetic interference or improved shielding performance—common in sensitive electronics environments and specific industrial standards (availability depends on the selected series).
Rack-mounted fans are designed for installation at the 19" level to support airflow management inside IT racks—helping reduce hot spots and improve airflow direction in combination with your overall rack cooling strategy.
