GW280H2C-L02 220V AC Metal Fan 280×280×80mm – Bitmain Antrack V1 Hydro

GW280H2C-L02 220V AC Industrial Metal Cooling Fan 280×280×80 mm – Antminer V1 Hydro Cooling Cabinet Replacement (Bitmain Antrack V1)

The GW280H2C-L02 is a 220 V industrial AC metal cooling fan — 280 × 280 × 80 mm, manufactured by ACDCFAN. It features a die-cast aluminium frame and metal blades, engineered for heavy-duty thermal management in industrial equipment such as inverters, machinery — and specifically as the replacement fan for the Bitmain Antrack V1 (Antminer V1 Hydro Cooling Cabinet / Bitmain Antrack V1 Hydro Cooling Mining Rack). When a fan fails in an Antrack V1 rack, thermal headroom collapses on the affected zone almost immediately — a spare or a fast swap-out is a fleet-uptime requirement, not an option.

Why This Fan for the Antrack V1

The Antrack V1 hydro cabinet dissipates the residual heat rejected by its cooling loop through high-throughput axial fans of this exact 280 × 280 × 80 mm form factor at 220 V AC. Using an under-spec'd or slower replacement fan cuts static pressure and airflow, which the cabinet's thermal-management logic cannot compensate for — the result is a warmer coolant loop, throttled miners inside the rack, and lost hash rate. The GW280H2C-L02 matches the OEM specification: up to 2,700 RPM, 150 W peak power draw, and the mechanical robustness needed for 24/7 duty in an industrial cabinet.

Die-Cast Aluminium & Metal Blades — Industrial Duty

Plastic-frame fans are cheap, but they warp under continuous operation at hydro-cabinet temperatures, throw imbalances into the bearings and eventually shatter. The die-cast aluminium frame on the GW280H2C-L02 is dimensionally stable across the full operating range, and the metal blades hold their pitch geometry over thousands of hours instead of drifting under thermal cycling. A ball bearing assembly handles the sustained loads without the acoustic and vibration drift typical of sleeve-bearing fans after a year of service — the reason ACDCFAN specifies this bearing class for industrial-duty units.

When to Replace an Antrack V1 Cabinet Fan

• Audible bearing noise — the classic early-warning sign of an impending fan failure on a rack.
• Reduced airflow — cabinet temperatures climbing without a matching change in coolant-loop behaviour.
• Visible blade damage — cracked, chipped or unbalanced blades after debris ingestion.
• Failed fan — no rotation on the affected axial position, kernel or BMS alarms on the rack controller.
• Preventive swap — planned replacement on a fleet-wide maintenance schedule to keep MTBF above the coolant-loop's tolerance.

Installation Notes

Confirm the failed unit is a 280 × 280 × 80 mm 220 V AC fan before ordering — measure the frame and read the label on the existing unit if in doubt. Power off the rack section, isolate the fan circuit, and unbolt the fan from its cabinet position. Note the airflow direction (usually stamped on the frame) and match the same orientation on the replacement — installing a fan backwards will pull cabinet air against the intended flow and defeat the whole thermal path. Re-torque the mounting bolts to the OEM value, restore power and verify the fan spins up cleanly with no bearing noise before returning the rack to full duty.
