The fans include two ball-bearings and are characterised by low power consumption, low noise and high air performance. The air performance diagram shows a good linearity for air flow via air pressure, therefore the fans are adapted for any applications with best results. Protection against excessive temperature is included. Standard models are printed boldface.

Very stable metal housing, impeller made from PBT 30%FG, high precision ball-bearings and operating temperatures -40…+70°C are further highlights of these fans. Fan models with sleeve bearings or for high temperature up to 90°C or IP55 protected fans are available on request.
