Fans for power transformers
Vostermans Ventilation developed Multifan fans for cooling power transformers. The shape of the tube
with a built-in fan are designed to obtain an optimal airow. The specially constructed tube made of
HDPE (High Density Poly Ethylene) are UV resistant, corrosion proof and light-weighted.
The motor with aluminum extrusion prole is a TEAO motor (Totally Enclosed Air Over motor). For proper cooling,
the motor has to be mounted in the airstream. Our motors also meet CE standards and fulll the international
specications of approved institutes such as CSA and UL. They are produced in accordance with IP55 standard (dust
and water resistant) and the materials used meet the standard of insulation class F (resistance to temperatures up to
155°C / 311°F).
