Blower

High-volume air movement systems used for process cooling, ventilation, or exhaust applications where significant airflow is required.

Pfannenberg | PTB Series Centrifugal Blowers

Pfannenberg is the inventor of the Filterfan®, but their blowers are sourced for applications where air must be pushed through long ducts or across high-heat components like VFD heat sinks. They are known for their extreme service life (up to 40,000 hours) and their ability to maintain high airflow even as filters become dirty.

PTF 32.000

Model Number: 18611600037

Airflow up to 275 m³/h; high static pressure; optimized for narrow enclosures.

Key Technical Specifications:

  • Specifically designed to maintain consistent airflow in cabinets packed tightly with components that would “choke” a standard axial fan.

  • The 90-degree air discharge allows for precise “spot cooling” of specific hot-spots, such as large power supplies or servo drives.

PTF 1200

Model Number: PTF61000LG

Exhausts hot air from the top of the cabinet; NEMA Type 12/3R protection options.

Key Technical Specifications:

  • Mounted at the highest point of the enclosure to assist the natural upward movement of heat, significantly increasing cooling efficiency.

  • The blower assembly sits partially inside the cabinet, keeping the exterior profile slim and preventing accidental damage in busy factory aisles.

Stego | StegoJet & 19" Fan Trays

Stego is a specialist in niche thermal solutions. Their blowers are often sourced for “targeted cooling”—directing a concentrated stream of air exactly where it’s needed. They are particularly famous in the networking and server world for their high-quality 19-inch rack-mount blower trays.

StegoJet SJ 019

Model Number: 01900.0-00

Adjustable air nozzle; high-speed air stream; can be aimed in almost any direction.

Key Technical Specifications:

  • Features a multi-directional nozzle that can be aimed at a specific component that is prone to overheating, providing targeted relief without cooling the entire cabinet.

  • Can be mounted on the DIN rail or fixed with screws, allowing it to be added to existing cabinets as a “problem solver” for heat issues.

LE019 19" Fan Tray

Model Number: 01930.0-00

1U or 2U heights; integrated thermostats; high-volume air circulation for server racks.

Key Technical Specifications:

  • Often configured with multiple independent blowers in a single tray, ensuring that if one motor fails, the remaining units continue to protect the equipment.

  • Frequently sourced with a built-in thermostat, allowing the blowers to only run when a specific temperature threshold is met, saving energy and extending fan life.
