Orion Launches Challenger Sealed Sleeve Fans

Orion Fans has developed the Challenger series of sealed sleeve-bearing DC fans. The fans feature a sealed sleeve-bearing system that is said to have a long life expectancy of more than 50,000 hours at 25C (L10). Mean time between failures is in excess of 200,000 hours, according to Orion.

The sealed sleeve fan technology retains lubricant by using metal foils that serve as a guard to redirect and recycle the lubricant. The fans were developed in response to demand for fans with a wider temperature range and longer life than sleeve-bearing fans, but at a lower cost in comparison to traditional ball bearing fans.

The Challenger series sealed sleeve fans are offered in seven sizes, ranging from 40 x 10mm to 120 x 38mm, and are available in 12VDC and 24VDC versions. Airflow ranges from 6.7 to 105 CFM. The fans feature a brushless DC, auto restart, polarity-protected motor with a UL94V-0 plastic frame and impeller. The sealed sleeve fans are RoHS compliant. The sealed sleeve Challenger series fans are available from stock at Allied Electronics in North America and RS Components in Europe.
