To get the IP68 certification level, Sunon engineers developed a complete potting process coating for the motors of the IP68 fans, whereas usual models have glue coating or conformal coating. This specific molding process covered 100% of the stator, coil, circuit and wire by shaped resin, preventing the system from dust and water intrusion. Anti-rust treatment (salt spray protection) is also available as an option.
Several tests have been conducted with success under extremely dusty and wet conditions: 8 hours under a maximum depression of 2 kPa, 1 hour under 1 m of water, etc
Sunon IP68 fans are dedicated to harsh environment applications, like outdoor telecom, solar farms inverters, factories, onboard automotive, outdoor LED lightings etc
Three models are already available: 80 x 80 x 25 mm, 80 x 80 x 32 mm, 92 x 92 x 25 mm, voltage from 12 to 48 V, and airflow from 50 to 75CFM. Several more will be marketed this year. Customization is possible on demand for large series.
