DEVELOPS LOW PROFILE, STACKABLE DC FANS FOR TELECOM, APPLIANCE APPLICATIONS

Dallas-based Orion Fans has developed a series of low profile, stackable DC fans. Designated the OD172SAPL Series, the stackable, low profile, aluminum DC fans feature two flat sides and measure just 172 x 150 x 38mm. “While comparable fans of this size are round, the SAPL-frame features two flat sides that allow for stacking them side-by-side with no wasted space,” said David Luna, Orion Fans’ product marketing manager.  “As a result, these fans are much lower profile than typical 172mm round fans, making them ideal for a variety of applications, including telecom racks and enclosures, as well as for ventilation in appliances and white goods, such as cooling and refrigeration units.”The OD172SAPL Series stackable fans are constructed with a diecast aluminum frame and a PBT, UL94V-0 plastic impeller. The fans feature a dual ball bearing system and a polarity protected, auto restart, brushless DC motor.  The DC fans are also available with tachometer (5V/TTL) output, locked rotor alarm (5V/TTL), as well as thermistor, PWM and constant speed controls. Available in 12, 24 and 48V DC versions, the OD172SAPL fans feature voltage ranges from 8 to 14, 15 to 28, and 28 to 63, respectively. Airflow ranges from 120 to 225 CFM, with speeds from 2000 to 4000 RPM and maximum static pressure from 0.35 to 0.73H2O. Operating temperature ranges from -20°C to +80°C, and life expectancy (L10) is to 60,000 hours.
