Sanyo Denki waterproof long life fans for harsh environments

Designed and tested to the highest standard, these axial fans cater to the specific needs of equipment requiring extended, maintenance-free operation. Let's look at this video showing the key design features that make the 9WL series a top choice for harsh environments.

See the design features and construction of a long-life waterproof fan:

Robust Build

The 9WL series boasts an aluminium frame, ensuring not only durability but also resistance to corrosion and impact, and the plastic impeller is flame-retardant for safety in the event of a fire. These features are crucial for maintaining performance in challenging industrial environments.

Long Lifespan

Boasting an exceptional lifespan of 180,000 hours (approximately 20 years) at 60 degrees, the 9WL series surpasses the life of conventional splash-proof fans. This extended lifespan is ideal for equipment that demands uninterrupted operation over extended periods. The improved lifetime is a result of a high-quality metal frame construction, an uprated drive circuit and careful design of the fan structure to reduce the heating of the dual ball bearings.

IP68 Water and Dust Resistance

Achieving an IP68 rating, these fans are resistant to water and dust, capable of withstanding immersion in 1m of water for up to 30 minutes. This makes them an ideal choice for wet or outdoor applications The IP68 rating is ensured by using an encapsulated motor and a fully sealed cable outlet.

High Air Flow and Static Pressure

Offering a maximum airflow of 3.7m³/min (130.6 CFM) and static pressure of 430Pa (1.72" H2O) (depending on fan size) the 9WL series excels in providing reliable cooling.

PWM Speed Control

Featuring PWM speed control functionality, users gain precise control over rotational speeds. This not only minimizes power consumption but also reduces noise, providing a tailored cooling solution for diverse applications. These fans offer a speed range of 2300RPM to 17500RPM. A suitable PWM controller might be the Sanyo Denki (121-9768) . It drives up to four fans and powered by the fan voltage. Fan speed can be adjusted by a thermistor, resistor or a voltage control line.

Efficient Power Management

The 9WL series strikes a balance between high-energy efficiency and low power consumption, ensuring optimal performance without compromising on environmental considerations. The devices offer an operating supply voltage range of 12VDC to 48VDC, and a power rating range of 1.2W to 23.04W.

Wide Range of Applications

The versatility of the Sanyo Denki San Ace 9WL series makes it suitable for various applications, including servers and computers, electrical enclosures, heating systems, air conditioning units, industrial inverters, PV inverters, rapid EV charging stations, and digital signage.

A Range to Meet Every Requirement

The 9WL long-life waterproof fans series are available in a wide range of standard sizes, covering most application requirements. The axial fan frame sizes include 40mm, 60mm, 80mm, 92mm, and 140mm, with various frame thicknesses such as 25mm, 28mm, 38mm, and 51mm.

In conclusion, the Sanyo Denki San Ace 9WL series represents a cutting-edge solution for design engineers seeking to elevate the performance and longevity of their industrial equipment. With a focus on robustness, efficiency, and user-friendly installation, these axial fans provide a reliable cooling solution for a wide spectrum of applications.
