Delta Fans for Servers, Telecom and Industrial Equipment

Delta manufactures DC axial fans and centrifugal blowers for electronic equipment requiring continuous and reliable thermal management. Available options range from compact high-speed fans for 1U servers to 48V telecom fans and IP68 models for outdoor industrial systems.

Selecting a fan requires more than matching its dimensions. Engineers must evaluate airflow resistance, rated voltage, current, control interface, acoustic limits and environmental exposure.

Recommended Delta Fan Models

Specifications apply to the complete model numbers shown. Suffix variants may have different connectors, wire functions, control signals or environmental ratings.

Delta Fans for Servers and Storage Systems

Servers and storage systems contain CPUs, GPUs, memory, power converters, HDDs, SSDs and network controllers within a restricted chassis. Cooling air must pass through dense heat sinks, drive cages and backplanes before leaving the enclosure.

Delta lists FFB, GFB, QFR, PFB and PFR among its fan series for server and storage applications.

Main Server Cooling Requirements

Server fans normally require:

• High static pressure

• Compact frame dimensions

• High airflow at system resistance

• Tachometer feedback

• PWM speed control

• Locked-rotor protection

• Continuous-duty bearing performance

• Low variation between multiple fans

Free-air CFM should not be used as the only selection value. Actual airflow depends on resistance from heat sinks, drive bays, grilles and internal partitions.

PFR Series for High-Density Servers

The Delta PFR Series is suitable for restrictive server airflow paths. Representative 60 mm, 80 mm, 92 mm and 120 mm models provide PWM control and tachometer feedback.

Examples include:

• PFR0612XHE-SP00 for compact 1U equipment

• PFR0812XHE-SP00 for GPU and storage nodes

• PFR0912XHE-SP00 for high-density computing chassis

• PFR1212DHE-SP00 for larger servers and storage enclosures

The SP00 configurations listed above use four lead wires and support speed monitoring and PWM control. This allows the server controller to increase fan speed at high load and reduce speed during lower thermal demand.

PFB Series for High Airflow and Pressure

PFB fans are another option for server and storage equipment requiring strong airflow and static pressure. They are available in several dimensions, voltage ratings and interface configurations.

PFB models are commonly considered for:

• RAID storage arrays

• Disk expansion enclosures

• Server power supplies

• High-density HDD systems

• Network storage platforms

• Large computing chassis

Higher-speed PFB and PFR fans can draw several amperes and produce substantial acoustic noise. The power circuit and control strategy must be designed for the rated and starting current.

Delta Fans for Telecom and Networking Equipment

Telecom equipment often uses narrow front-to-rear airflow paths containing line cards, optical modules, processors and power converters. Outdoor platforms may also be exposed to dust, humidity and water.

Typical applications include:

• Core network switches

• Enterprise routers

• Optical transmission systems

• Base-station equipment

• Small-cell systems

• Telecom power supplies

• Outdoor communication cabinets

• Edge network platforms

Voltage Selection for Telecom Systems

Compact networking equipment may use 12V fans, while telecom power architectures commonly use 48V DC.

PFB1248UHE is a 120 × 120 × 38 mm, 48V fan providing 252.85 CFM maximum airflow and 1.412 inH₂O maximum static pressure. It is suitable for systems with an existing 48V supply and high cooling demand.

A 48V fan is not automatically more powerful than a 12V or 24V fan. Its main advantage is compatibility with 48V power systems and lower current for a given power level.

Telecom Fan Selection Priorities

For indoor networking equipment, check:

• Available fan dimensions

• Airflow through line cards and heat sinks

• System noise requirement

• PWM control

• Tachometer feedback

• Fan redundancy

• Hot-swap connector requirements

For outdoor telecom systems, also check:

• IP protection rating

• Operating-temperature range

• Humidity resistance

• Dust exposure

• Water and salt-fog exposure

• UV and enclosure conditions

The standard model and the IP-rated version of the same fan family should not be treated as equivalent unless all suffix and protection requirements match.

Delta Fans for Industrial Equipment

Industrial systems may operate continuously around power semiconductors, transformers, motors and control electronics. Applications can involve dust, moisture, vibration and wider ambient-temperature ranges.

Typical equipment includes:

• Industrial power supplies

• Motor drives

• Inverters and converters

• EV charging equipment

• Battery energy storage systems

• Solar inverters

• UPS systems

• Automation controllers

• Semiconductor equipment

• Outdoor electrical cabinets

Delta provides standard industrial fans and IP-rated models for environmental protection. Its industrial application range includes fans rated up to IP68.

PFB1224SE-00P6 for Harsh Environments

PFB1224SE-00P6 is a 24V, 120 × 120 × 38 mm IP68 axial fan. It provides:

• 265.43 CFM maximum airflow

• 2.070 inH₂O maximum static pressure

• Tachometer output

• PWM speed control

• IP68 protection

• Operating temperature from -10°C to +70°C

This combination is suitable for high-power outdoor equipment requiring both strong cooling performance and environmental protection.
