SEALMINER A3 Pro Air
Bitcoin miner from Bitdeer. The efficiency pick of the air cooled A3 range. Single phase supply and conventional shelf mounting, no liquid infrastructure required.
About the SEALMINER A3 Pro Air
The SEALMINER A3 Pro Air is the efficiency pick of Bitdeer's air cooled A3 range. It runs at 290 TH/s on 3,625 W, which is 12.5 J/TH, and delivers more hashrate than the A3 Air on less power. It is among the most efficient air cooled SHA-256 machines in our catalog and among those with the most hashrate per machine; the SEALMINER A4 Pro Air and the Antminer S23 are more efficient still.
It runs on single phase supply at 220 to 277 V and uses about 87 kWh a day per unit, with conventional shelf mounting and no liquid infrastructure. The site provides airflow and heat exhaust, hot and cold separation, and sound insulation near housing, since it runs at about 75 dB; the rated range is 5 to 45 °C ambient. Each unit measures 197 × 365 × 292 mm and weighs 15.5 kg, like every SEALMINER air model in our catalog.

Air cooling. The simplest of the three routes and the lowest infrastructure cost. Sustained ambient above the rated range derates performance, so size the exhaust for the warmest week.
Energy only: 3,625 W rated power, 24 hours, one unit. Cooling overhead and PSU losses not included; no revenue assumptions.

Read before you buy the SEALMINER A3 Pro Air
The breakeven power price, and why we ask for yours first
Every machine has an electricity price above which it stops making money. Work that number out and most of the hardware decision answers itself.
Air, hydro or immersion: matching cooling to your site
The cooling route you pick decides which machines you can even consider, how loud your site is, and how much you spend before the first miner is switched on.
How loud is a mining site, and what to do about it
Noise is the most common reason a running site gets shut down, and the least often budgeted for. What the numbers mean, and what actually works.
