Customer Requirement
An OEM manufacturing vacuum packaging machinery submitted an inquiry for 600 units of axial fans. These axial fans are used to be integrated into their system for cooling. The primary spatial constraint is a 92x92x25 mm dimensional footprint. The mounting interface was 82.5×82.5 mm hole spacing. To ensure adequate heat dissipation, the core performance target was an airflow rate of 0.7 m³/min.
The electrical requirement was strict, requiring a 220V AC power source and a simple two-wire connection. Most critically, the fan had to possess ETL certification to comply with safety and market access standards for North America.
Engineering Solution
LONGWELL’s existing LWAA9225 series can meet customers’ requirements after minor adjustments. This fan uses an aluminum alloy frame and a plastic impeller. The chosen fan provides a 37% performance margin over the customer’s minimal requirement by delivering up to 34 CFM at 60Hz. It had a higher maximum temperature tolerance than the replaced unit, with an operating temperature range of -10°C to +65°C. The LWAA2E925SS-5PYW-17 was the final model that had been proposed.

Frequently Asked Questions
Q: What is the lead time for a 600-unit order of the LWAA2E925SS-5PYW-17 axial fan?
A: The 600 units of LWAA2E925SS-5PYW-17 axial fan usually need 15 to 30 days to produce. For a stocked diameter size sample, it usually needs 1-3 days.
Q: Why is LWAA2E925SS-5PYW-17 used in an application that previously used a -20°C-rated axial fan?
A: The fan is for an indoor vacuum packaging machine. The typical install temperature will not fall to -20°C in a factory environment. The -10°C to +65°C range of the LONGWELL axial fan is a standard, robust specification for industrial-grade components intended for indoor use.
Q: Is this fan available for a 115V AC supply for the US market?
A: As the customer requires, the specific LWAA2E925SS-5PYW-17 model is rated for 220V AC. The 115V AC versions can be tailored for the US market.
Q: What are the key advantages of the LONGWELL axial fan compared to the original model?
A: The LONGWELL LWAA2E925SS-5PYW-17 model delivers up to 34 CFM airflow, providing a more effective cooling performance. The axial fan fully meets the installation space requirements, and no further modifications are needed.
