Costech A17T12SWB-M00 — 172x55mm AC Axial Fan, 115V, 2-Wire, All-Metal

Costech · AC Axial Fan · 115VAC · 17cm / 172x55mm · 2-Wire · All-Metal Frame

The Costech A17T12SWB-M00 is a 172 x 55 mm (17 cm / 6.7 inch) AC axial cooling fan built around an all-metal frame and 115 VAC single-phase input. With its 2-wire line/neutral hookup, it is a direct drop-in thermal-management choice for legacy North American cabinets, machine tools, and process equipment that already runs on US-spec mains. Costech is a third-party industrial-fan OEM widely used to replace aging EBM-papst, Sanyo Denki, and NMB units that have gone EOL on Allen-Bradley, Siemens, and Mitsubishi drive cabinets.

1. Key Technical Specifications & Overview

2. Application Scenarios — Where It Fits

The A17T12SWB-M00 sits between the 120 mm and 220 mm AC fan classes, so it is the natural upgrade path for cabinets that need more airflow than a 120 mm unit can deliver but do not have the cut-out for a full 220 mm frame. It is routinely used as a thermal-management drop-in on the following platforms at our Allen-Bradley, Siemens, Mitsubishi, and Omron customers' sites.

• Industrial drive cabinets — PowerFlex 525 / 755, SINAMICS G120, MR-J4 amplifier racks, and Yaskawa Σ-7 servo bays where the original EBM 172x51 has gone EOL.
• Welding and plasma equipment — Lincoln, Miller, and Hypertherm-style inverter welders that use a 115 VAC main to drive the heatsink blower.
• CNC machines — spindle cooler and electrical-cabinet exhaust on Fanuc 0i-MD / 30i-B and Schneider Lexium-based retrofits.
• HVAC and building automation — control-panel ventilation, fan-coil blowers, and clean-air handling units running on US-spec 115 VAC.
• Server and telecom rooms — rack-end exhaust boosters and PDU cooling on legacy US-spec branch circuits.
• Process and packaging lines — Panasonic FP7 and KEYENCE vision-cabinet enclosures that need steady positive airflow.

3. Integration & Wiring Notes

Because the A17T12SWB-M00 is a 2-wire AC device, integration is intentionally simple. There is no PWM, no tach, and no alarm pin — if 115 VAC is present, the fan runs. That makes it an excellent replacement for older EBM-papst and Sanyo Denki units in cabinets that were never designed for tach feedback. A few wiring points our customers most often ask us to confirm:

• Polarity is not observed on the 2-wire hookup. Connect the two leads to Line (L) and Neutral (N) of a 115 VAC, 50/60 Hz supply. Reversing them does not change rotation direction on this single-phase shaded-pole style motor.
• No DC link to drive electronics. The fan must be powered directly from mains or a dedicated 115 VAC control transformer — never from 24 VDC logic power or PLC relay outputs.
• Airflow direction is fixed by the label and impeller design. Confirm the airflow arrow on the frame before mounting; blowing the wrong way will trap heat inside the cabinet instead of exhausting it.
• Grounding is handled by the metal frame contact with the cabinet sheet metal. For EMC-sensitive sites, bond the fan housing to chassis ground with a short pigtail.
• No tach / no alarm output. If your existing monitoring logic relies on a tacho signal (e.g., on Siemens SIMOTION or Allen-Bradley GuardLogix safety routines), add an external current-monitoring relay on the AC line.
• EMI consideration. AC shaded-pole fans can inject line noise. For KEYENCE vision and Panasonic laser-sensor panels, route the AC line through a small line filter to keep the image clean.

If you are upgrading a cabinet that still uses a 120 mm or 80 mm fan, our PLC error-code lookup and PLC analog calculator pages help you size the new thermal envelope against the existing I/O heat budget before you commit to a frame change.

4. Installation & Commissioning Tips

A 172 mm all-metal AC fan is a heavy-duty device, and a clean install pays for itself in service life. The steps below are the same ones our China sourcing QC team runs on every batch before it leaves the warehouse.

1. Verify the cut-out is 172 x 172 mm with a minimum 55 mm depth behind the panel. The all-metal frame is rigid and will not flex to fit a non-square opening.
2. Mount with four M4 or M5 screws on the corner bosses. Use a split-lock washer on each screw to absorb vibration over the long term — the all-metal construction is stiffer than plastic, but vibration at line frequency (50/60 Hz) is still present.
3. Install a finger guard on the intake side. The exposed metal impeller is a real pinch hazard and most site safety audits will not pass without one.
4. Apply anti-vibration grommets between the fan frame and the cabinet wall if the cabinet is near a noise-sensitive measurement station (common in KEYENCE vision cells).
5. Pre-lubricate the bearing with a single drop of light machine oil on each bearing access hole before first power-on. Sleeve bearings benefit from a 200-hour break-in re-lube schedule in continuous-run applications.
6. Power-on commissioning — apply 115 VAC, confirm rotation direction matches the airflow label, measure inrush current with a clamp meter, and log the cabinet-internal delta-T after 30 minutes.
7. Document the swap in the cabinet's real-time parts log so that the next maintenance visit can quickly find a matching replacement.

For engineers who want to validate the thermal numbers on a bench, the PLC Hex to Float and Modbus CRC tools on KOEED are useful for decoding the tacho register of any companion 24 VDC fan you keep as a redundant unit on the same backplane.

5. Procurement, Warranty & Lead Time
