ebm-papst RL 65 Series DC Centrifugal Fan, 61 m³/h, 12V, 4900 RPM, Ball Bearing RL65-21/12H

The ebm-papst RL65-21/12H is a high-performance DC centrifugal fan designed specifically for industrial, HVAC, laboratory, and electronics cooling applications. With a compact form factor measuring 93.5 mm in height, 97 mm in width, and 33 mm in depth, this fan provides versatility in installation across confined spaces or equipment housings.

Powered by 12V DC, the RL65-21/12H delivers an air flow of up to 61 cubic meters per hour, making it suitable for efficient air movement in demanding environments. Its ball bearing design ensures smooth, reliable operation and prolonged service life, while the electronically commutated external rotor motor delivers high energy efficiency, reduced noise, and low maintenance needs.

This model features a centrifugal blower with radial direction flow, supporting applications such as ventilation, air conditioning, cooling of electrical panels, and other thermal management systems. The PWM sensor output offers flexible speed control and system integration for advanced cooling strategies in automation, electronics, and industrial machinery.

The RL65-21/12H fan incorporates electronic protection against reverse polarity, locked rotor, and overload situations, enhancing operational safety. The impeller is constructed from fibreglass-reinforced plastic with a sheet steel base, contributing to overall ruggedness and resistance to harsh environments. The mounting hole diameter is 71 mm, and connection is achieved via two leads (AWG22 TR64), stripped and tinned for easy installation.

Noise emissions are limited to 66 dB, which is suitable for both industrial and commercial contexts where acoustic comfort is critical. The fan’s wire terminal type and electronically commutated design make it ideal for integration in modern HVAC systems, laboratory equipment, automation panels, and electronic enclosure cooling.

Typical applications span industrial ventilation, laboratory thermal control, electronics/IT cooling, manufacturing machinery, environmental chambers, and HVAC air movement where precision, reliability, and long operational life are required.

Centrifugal blower optimized for continuous DC operation in industrial and laboratory environments. Robust construction with ball bearing and plastic-steel body for durability and heat resistance. Features PWM output for compatible speed regulation and feedback integration in automated systems.

Compact size supports installations in confined spaces and equipment enclosures. Safety features include electronic protection against polarity reversal, locked rotor, and overload.
