Oil Proof Fans San Ace 40WF, San Ace 60WF, San Ace 80WF, and San Ace 92WF

Oil Proof Fans San Ace 40WF, San Ace 60WF, San Ace 80WF, and San Ace 92WF

In the fields of industrial automation and CNC machine tools, core equipment such as servo amplifiers and controllers often need to operate continuously in harsh environments filled with oil mist. To ensure the stability and reliability of these high heat generating devices, efficient cooling fans are indispensable. The new generation San Ace 40WF, 60WF, 80WF, and 92WF 9WFA oil proof fans launched by Sanyo Denki provide an ideal solution for industrial cooling due to their excellent oil resistance, high airflow, and high static pressure characteristics. This article provides a detailed analysis of the technical characteristics, performance parameters, and application advantages of these four products.

Product Overview and Technical Features

The new generation San Ace oil proof fan is designed to meet the harsh challenges of factory automation environments. Its core technological improvements are reflected in two aspects:

Enhanced electrical protection: The electrical components of the fan, including windings and control circuits, are coated with specialized protective materials with excellent oil resistance. This coating effectively blocks the erosion and short circuit risk of oil mist on the circuit board, significantly improving the long-term reliability of the product in harsh environments.

Optimize mechanical structure: In order to prevent the accumulation of oil and dust from causing the fan to jam, the new model has increased the gap between the blade tip and the inner surface of the frame in the design. This improvement ensures that the fan can rotate smoothly and maintain stable cooling performance even after long-term operation.

Size and compatibility

The new model maintains the same installation dimensions and hole spacing as the current series of products, ensuring seamless compatibility as an upgraded replacement. The specific dimensions are as follows:

San Ace 40WF：40mm × 40mm × 20mm

San Ace 60WF：60mm × 60mm × 25mm

San Ace 80WF: 80mm x 80mm x 20mm (thinner than the conventional 25mm thickness)

San Ace 92WF：92mm × 92mm × 25mm

All models have a rated voltage of 24V DC to meet the mainstream power supply standards in factory automation. Its expected lifespan can reach 40000 hours at 60 ℃ (with a survival rate of 90%), and the reference lifespan at 40 ℃ is as high as 70000 hours, fully meeting the needs of industrial equipment for long maintenance cycles.

Core performance parameters

The San Ace 40WF, 60WF, 80WF, and 92WF have achieved a comprehensive leap in performance. The following table summarizes the key parameters of each model at rated voltage:

Model Rated current (A) Rated speed (min ⁻¹) Maximum air volume (m ³/min) Maximum static pressure (Pa) Noise (dB [A])

9WFA0424G6001 0.11 17,000 0.31 170 48

9WFA0624G6001 0.16 7,700 0.79 158 48

9WFA0824G6001 0.15 6,000 1.44 105 48

9WFA0924G2001 0.58 9,600 3.10 380 63

From the data, it can be seen that the 92WF model provides the highest air volume and static pressure, suitable for overall heat dissipation of large control cabinets; The 40WF to 80WF models strike a balance between compact size and good heat dissipation performance, with noise control at a lower level of 48dB (A), making them ideal for installation in equipment near personnel work areas.

Performance comparison and technological innovation

Compared with the previous generation product, the new San Ace oil proof fan achieves significant improvements in air volume and static pressure at the same size. Taking the 80WF model as an example, although its thickness has been reduced from 25mm to 20mm, its maximum air volume and maximum static pressure have surpassed the previous generation products. The maximum static pressure of the 92WF model has reached 1.49 times that of the previous generation.

This performance breakthrough stems from the following key technological innovations:

Fluid dynamics optimization of impeller and frame: The R&D team has redesigned the number, length, angle of blades, and the number and shape of frame spokes through extensive simulation and actual evaluation, and found the optimal aerodynamic combination. This optimization not only improves the airflow efficiency, but also enhances the mechanical strength of the frame, effectively suppressing the vibration caused by the increase in speed.

Efficient motor and drive circuit: The new model adopts a redesigned stator structure and a more efficient motor core, while upgrading the drive circuit components. This causes the overall power consumption of the fan to decrease while the speed increases. Under the same air output conditions, the power consumption of the new 80WF is reduced by about 25% compared to the previous generation, while the static pressure is higher in most working ranges, achieving a dual breakthrough in performance and energy efficiency.
