SealMiner A3 Pro Air for sale, 290Th/s 3625W Mining Bitcoin

SealMiner A3 Pro Air for sale

The SealMiner A3 Pro Air from Bitdeer is a high-performance Bitcoin mining machine designed for SHA-256 algorithm cryptocurrencies. It delivers an impressive hashrate of 290 TH/s with a power consumption of 3,625 W, giving it an efficiency of approximately 12.5 J/TH. This efficiency positions it as one of the most capable air-cooled miners available, combining power with energy optimization for demanding mining operations.

The SealMiner A3 Pro Air is built with advanced air-cooling technology that ensures stable thermal management under heavy loads. Equipped with durable high-speed fans and an optimized airflow system, it effectively reduces heat build-up and prevents performance throttling during extended operation. The cooling design allows the miner to maintain consistent output while safeguarding the internal SEAL chips from overheating, making it reliable for continuous 24/7 use.

Durability and stability are central to the SealMiner A3 Pro Air’s design. It is engineered with a compact form factor, weighing around 15.5 kg and measuring approximately 365 × 292 × 197 mm, making it suitable for efficient deployment in rack-based or modular mining setups. The robust chassis and streamlined airflow design reduce dust accumulation, minimize wear on moving parts, and extend the overall lifespan of the machine.

Noise control has also been taken into account. While most air-cooled miners operate at relatively high decibel levels, the SealMiner A3 Pro Air achieves a balanced noise output of around 75 dB. This makes it manageable for industrial mining environments where multiple units operate simultaneously, while still maintaining effective cooling performance.

Another key strength of the SealMiner A3 Pro Air is its efficient power conversion. Its power supply system is capable of achieving conversion rates of up to 97%, meaning that nearly all input energy is utilized for hashing work rather than lost as excess heat. This efficiency reduces unnecessary overhead and allows operators to maximize returns, particularly in regions where electricity costs are a significant factor in mining profitability.

Flexibility in deployment is a major advantage of the SealMiner A3 Pro Air. With a wide operating temperature range from –20 °C to 45 °C and tolerance for humidity up to 90%, the miner is designed to function in diverse environmental conditions. Its air-cooled system eliminates the need for additional infrastructure such as hydro-cooling setups, making it easier to install and maintain. This simplicity is particularly valuable for mining operations that want high performance without the complexity of liquid-cooling systems.

Performance stability is further enhanced by the SEAL chip technology powering the SealMiner A3 Pro Air. These chips are engineered for long-term efficiency and reliability, allowing the machine to sustain high hash rates with minimal fluctuations. Combined with intelligent firmware control, users can expect steady performance and dependable results across varying voltage and environmental conditions.

Overall, the SealMiner A3 Pro Air delivers a powerful balance of speed, efficiency, and practicality. With its 290 TH/s hashrate, 12.5 J/TH efficiency, robust air-cooling system, and flexible deployment capabilities, it stands out as a top choice for miners seeking reliable, high-performance hardware without additional infrastructure requirements. Whether used in large-scale industrial farms or smaller setups, the SealMiner A3 Pro Air offers the durability, efficiency, and consistent output necessary for modern Bitcoin mining.

Specifications of SealMiner A3 Pro Air

First of all, thank you for your interest and support to X-ON MINING. In order to avoid misunderstandings in the process of purchasing a miner, please read all the following notes carefully before placing your order. Thank you very much for your understanding!

1 – Given the specific dynamics of the miner market, when we receive your payment, the miner’s price may have changed and we may need to refund your order.  

We use batch processing for all mining machine orders, and the quantity of each batch is very limited.  Even if the same type of mining machine, different batches of mining machine prices are not the same.  They’re selling fast.  Given the highly variable market and demand, the prices of stock miners may vary from day to day.  Therefore, so there is a possibility that by the time we receive your payment, the price of the mining machine has gone up and we need to refund your order.

2 – About stock miners

The delivery date of stock asic miner is 3-7 working days.  Once we receive your order, we will immediately notify our technical center staff to test the machine you ordered to make sure it works well.  We’ll also send you a video for confirmation.  We will send the machine to you only after we confirm that all the properties of the machine are correct.  Then, we will give the machine to our freight forwarder.  We will update the waybill number on our website and you will receive a detailed email.

3 – About pre-purchase miners

The actual delivery date of the pre-ordered miner depends on the miner delivery date of the factory.  We will indicate on the order page the estimated delivery month of the pre-ordered miner for your consideration.  However, there may still be a delay in delivery.  First, if the factory delivery date is delayed, then the delivery of the X-ON MINING Mining machine will also be delayed.  It is also possible that the plant will not be able to produce the mining machine within the expected time, in which case we will process your order for a refund.
