Description
The SUNON UB5U3-700 is an ultra-compact MagLev mini DC blower engineered for high-density, space-constrained industrial electronics. Measuring 30 x 30 x 3 mm (1.18 x 1.18 x 0.12 inches) with a lightweight 2.4 g (0.005 lbs) profile, this unit is constructed with a flame-retardant UL 94V-0 LCP frame and impeller. Powered by SUNON’s Vapo bearing and MagLev motor system, it delivers targeted static pressure while maintaining IP55 ingress protection with CE and UKCA safety approvals.
Key Features
- Ultra-thin 30 x 30 x 3 mm (1.18 x 1.18 x 0.12 inches) form factor constructed from flame-retardant UL 94V-0 thermoplastic LCP.
- MagLev motor system with a Vapo bearing architecture ensures friction-reduced 9500 RPM counter-clockwise rotation.
- Generates 88.18 Pa (0.354 inH2O) static pressure and 18.0 l/min (0.635 CFM) air volume at a low 0.36 W power draw.
- IP55 ingress protection rating paired with flexible UL10064, 32 AWG lead wires (+Red, -Black) for reliable connectivity.
- Integrated safety features include automatic motor shutdown with 10-second auto-restart for locked rotors and polarity protection.
