High-Performance Forced Air Circulation with Diagonal Fan Technology
The Rittal TopTherm fan-and-filter series sets the global gold standard for reliable, cost-effective enclosure ventilation. Engineered with advanced diagonal fan impeller technology, airflow is directed diagonally across the enclosure interior, creating uniform air distribution that completely eliminates localized heat pockets and hot spots around densely packed power electronics.
Tool-Free Snap-In Mounting & 10-Second Filter Mat Swaps
Installation requires zero screws or specialized tools. The entire fan assembly snaps securely into standardized rectangular enclosure cutouts using patented spring-loaded latching clamps. Routine maintenance is equally effortless: the ergonomic louvre grille unlatches with a light fingertip pull, swinging open on heavy-duty hinges to allow filter mat inspection or replacement in under 10 seconds without stopping production.
Intelligent Energy-Saving EC Fan Technology
Available with state-of-the-art electronically commutated (EC) motors, Rittal TopTherm fans consume up to 60% less electrical power than standard AC induction fans. Built-in speed control interfaces (0-10 V or PWM) dynamically adjust fan revolutions to match actual internal cabinet temperature, drastically reducing acoustic noise levels and extending bearing service life beyond 70,000 continuous operating hours.
Comprehensive Protection: Fine Dust, Hose-Proof, and EMC Shielding
Standard units deliver IP54 ingress protection against dust and liquid splashes. By inserting high-density fine filter mats, protection is elevated to IP55 / NEMA 12. For washdown environments, Rittal stainless steel hose-proof hoods upgrade protection to IP56, while specialized EMC versions prevent electromagnetic interference in radio-frequency sensitive switchboards.
