Product Overview
The San Ace 120 model 9G1224H1M037 is a 24VDC axial cooling fan in the standard 120 x 120 x 38 mm frame, the size most cabinets, chassis, and rack panels are already cut for. Rated at 24V with an operating range of 14 to 27.6V and a rated current of 0.22A, it moves up to 99 CFM at a rated 2600 RPM and develops a maximum static pressure of 70.4 Pa, which is what lets it keep pushing air through a filter or a crowded card cage instead of stalling at the grille. It carries a pulse sensor output and does not have a PWM control input, which matches the three-wire lead and white three-pin connector visible in the photos. Rated for -20 to +70 degrees Celsius, with an expected life of 40,000 hours at 60 degrees Celsius and 70,000 hours at 40 degrees Celsius. Weight is 330g. Conforms to UL, CSA, and EN standards and the RoHS directive.

Frequently Asked Questions
Has this fan actually been run, or is it just a visual check?
These fans were removed by us from telecom equipment and then inspected, cleaned, and checked for quality and performance. They are sold as used, working units, not as new stock.
What are the three wires for?
The 9G1224H1M037 has a pulse sensor output and no PWM control input, so the third conductor is the sensor line rather than a speed-control input. Individual pin assignment is not confirmed here - verify the wiring against the Sanyo Denki datasheet before you connect it.
Will it run below 24V?
The published operating voltage range is 14 to 27.6V. The 99 CFM, 2600 RPM, and 70.4 Pa figures are the rated-voltage numbers, so expect lower airflow and speed at the bottom of that range.
Will it drop into a standard 120mm fan opening?
The frame is the common 120 x 120 x 38 mm axial size with mounting ears at all four corners, as shown in the photos. Exact hole spacing and screw size are not confirmed here - measure your opening or check the datasheet before ordering hardware.
What am I taking on by buying a used telecom pull instead of a new fan?
You are buying a fan that already did a shift in service. It came out of telecom equipment, it was inspected, cleaned, and checked for performance before listing, and the photos are the spec for cosmetics: molded plastic frame, legible hub label, three-wire lead with its connector still attached. Remaining bearing life is not measured and not warranted, and running hours before removal are unknown, so this is the right buy for a spare, a retrofit, or a build where a working 24V 120mm fan matters more than a factory box. Shipping is $8 flat rate and free once your order passes $28, and orders leave our Idaho warehouse the same or next business day.
San Ace 120s spent their first career pushing air through telecom racks that were never allowed to go quiet, which is exactly why this one is still turning. Put 24V on it and let it go back to the steady, unglamorous work it was built for.
