  • High airflow of 185 CFM at 110 V and 245 CFM at 220 V for strong cooling
  • Ball-bearing design rated for 60000 hours at 40 °C for extended reliability
  • Wide temperature range from -20 °C to 70 °C suits harsh environments
  • Corrosion-resistant black-painted aluminium alloy frame for durable construction

AC case fan for industrial enclosures

The Fans SJ1738HA2 is a 172×150×38 mm axial fan that runs directly from 110 V or 220 V AC mains. It uses a ball-bearing motor rated for 60000 hours at 40 °C and delivers 185 CFM at 2850 rpm on 110 V or 245 CFM at 3450 rpm on 220 V. The die-cast aluminium frame is black-painted for corrosion resistance and the unit operates from -20 °C to 70 °C.

Suited for rack-mount gear and UPS cooling

This fan fits equipment that has a 161.5 mm hole pattern and an AC power feed, such as server racks, inverter cabinets or industrial enclosures. It is not for builds that need a DC-powered fan, a PWM signal wire, or a different mounting pitch. Buyers who want a quieter device below 54 dB-A should look elsewhere.

110 V / 220 V AC dual-voltage operation

The single specification that decides fitment is the AC voltage rating. The motor is designed for both 110 V and 220 V supplies, drawing 25 W at the lower voltage and 31 W at the higher voltage. Verify that your chassis provides mains power and the 161.5 mm mounting centres before ordering.

Questions about this item

How do I mount the 172×150×38 mm frame using the 161.5 mm hole spacing?

Align the fan’s four mounting holes to the 161.5 mm pitch on your chassis or panel, then secure with M4 screws; the black-painted aluminium alloy frame resists corrosion so no washers are required.

When should I plan to replace the ball-bearing assembly?

At 40 °C ambient the ball bearing is rated for 60,000 hours of continuous operation; schedule replacement once runtime approaches that figure or if noise rises above the quoted 54/57 dB-A.

What thermal limit will throttle sustained airflow first?

The fan is specified for ambient temperatures up to 70 °C; beyond that the motor insulation and bearing lubricant degrade, reducing the 185/245 CFM output before any other component fails.
