Panel Fan

High-efficiency cooling units designed for electrical enclosures to maintain optimal internal temperatures and protect sensitive electronics from heat failure.

Rittal | Blue e+ Fan-and-Filter Units

Rittal is the global leader in enclosure technology. Their “Blue e+” fan-and-filter units are sourced for their Diagonal Fan Technology, which provides a more even air distribution inside the cabinet compared to traditional axial fans. They are the “gold standard” for high-density cooling in industrial automation.

TopTherm (Standard)

Model Number: SK 3239.100

Tool-free assembly; air throughput 20–900 m³/h; IP54 to IP56 protection.

Key Technical Specifications:

  • Uses a unique blade design that spreads air diagonally throughout the enclosure, eliminating “hot spots” in corners where standard fans can’t reach.

  • Features a patented louvered grille latch that allows the filter mat to be replaced in seconds without any tools, reducing maintenance labor.

Blue e+ (EC Version)

Model Number: 3328540

Electronically commutated (EC) motors; 0–10V interface for speed control; up to 1,125 m³/h.

Key Technical Specifications:

  • Integrated tacho-signal output allows the PLC to monitor the fan speed and trigger an alarm if the fan stops or the filter is clogged.

  • When used with Rittal’s pleated filter mats, these units offer significantly higher throughput than traditional chopped-fiber filters.

nVent HOFFMAN | HF & T-Series Fans

nVent HOFFMAN is the premier choice for the North American market. They are sourced for their extreme ruggedness and Type 12/3R/4X ratings, which are essential for outdoor or wash-down environments. Their fans are designed to be “interchangeable,” meaning they often fit into the same cut-outs as other major brands.

HF Side-Mount

Model Number: HF1016414

Slim-fit design; composite or metal grilles; high-pressure static performance.

Key Technical Specifications:

  • Features a “click-fit” mounting system that allows the fan to be snapped into the cabinet cutout instantly without using screws or bolts.

  • Often sourced with reusable, washable foam filters, reducing the recurring cost of disposable synthetic mats in dusty environments.

T-Series (Outdoor)

Model Number: TFP61

Stainless steel options; designed to withstand rain, sleet, and ice; integrated heaters available.

Key Technical Specifications:

  • Specifically engineered to prevent water ingress during wind-driven rain while maintaining high-volume airflow for heat dissipation.

  • Designed with a very shallow installation depth, leaving more room for internal components like PLCs and VFDs.
