The sealed sleeve fan technology retains lubricant by using metal foils that serve as a guard to redirect and recycle the lubricant. The fans are offered in seven sizes ranging from 40 x 10 mm to 120 x 38 mm, and are available in 12 and 24 Vdc 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.
