Rittal’s Blue e+ Fan-and-Filter Unit with EMC Shielding: More Power for Your Enclosure Cooling
Discover Rittal’s Blue e+ fan-and-filter unit with EMC shielding for tool-free mounting on surfaces. Air throughput from 20–900 m³/h. Rittal Blue e+ fan-and-filter units help you to achieve your climate goals while at the same time reducing your energy costs. The 40% greater air throughput of the new fan-and-filter unit with pleated filter – compared to a chopped-fibre filter – is unrivalled by any other unit on the market.
You benefit from an enclosure cooling solution which combines power, efficiency and simplicity. Rittal’s fan-and-filter units are available in AC/DC, EC and EMC options. See how the new Blue e+ fan-and-filter units can contribute to decisive improvements in your daily operations.
Features & Benefits
Powerful
- More Performance: The 40% greater air throughput of the integrated pleated filter enables cost savings, as you can now choose a unit from a lower output class.
- Extended Service Life for Components: The unique diagonal fan technology provides for more even and constant ventilation of the enclosure.
Efficient
- Cost & Time Savings: Thanks to the 2-3 times longer replacement interval of the standard pleated filter.
Simple
- Simple Planning: Optimised parameterisation and product selection with tools such as RiTherm, RiPanel, Eplan Data Portal and ProPanel.
- Simple Conversion: Mounting cut-outs, protection ratings and output classes correspond to those of the previous generation of fan-and-filter units.
- Simple Assembly: Time savings thanks to tool-free mounting (simple snap-fit mounting on the enclosure).
- Simple Maintenance: Tool-free handling and simple filter mat replacement.
Pleated Filters
Lower Energy Costs
- The six times larger surface area compared to a standard chopped-fibre filter results in a lower pressure drop and enables faster dissipation of the waste heat from the enclosure.
- 80% greater air throughput with IP 55 protection compared to a chopped-fibre filter.
Improved Operational Reliability
- The material and construction of our pleated filters ensure that even tiny dust particles are retained reliably. Particles measuring just 0.3 micrometres can be filtered from the air. That is smaller than some viruses. In practical terms, significantly less dust enters the enclosure.
- 50% greater dust retention.
Reduced Service Costs
- Thanks to their larger surface, pleated filters boast a significantly higher retention capacity. This, in turn, means that maintenance intervals can be extended. Furthermore, Rittal’s pleated filters guarantee protection to IP 54 or IP 55 (when the pleated filter is used in conjunction with an absorber mat).
- 2–3 times longer maintenance intervals.
