Better performance from brushless DC fans
The Adda 15mm SlimLine range of brushless DC fans has been expanded to include versions with Hypro bearings and an extended intelligent cooling capability.
The distance across the flat surfaces is 150mm so making it ideal for use in standard 19in rack systems.
Both are available in 12, 24 or 48V supply voltage with six performance variants ranging from 210CFM at 55dB(A) to a remarkable 324cfm at 63dB(A).
This level of performance is due to the combination of small motor diameter and the newly designed housing and impeller blades.
With an aluminium housing, an impeller made from plastic UL 94 VO and with a rugged ball bearing system, the ETRI 350 series is VDE, UL, CSA and CE approved and these fans will be ideal for all applications that require high levels of cooling at relatively low noise levels.
They are particularly suitable for equipment such as telecommunication systems, large computer installations, heat exchangers and refrigeration cabinets.
Speed sensor and failure detection are available on all fans in the range.
