SealMiner A3 Air for sale, 260Th/s 3640W High-efficiency BTC Miner

SealMiner A3 Air for sale

The SealMiner A3 Air by Bitdeer is a next-generation Bitcoin mining machine designed for high performance, efficiency, and stability. Built specifically for the SHA-256 algorithm, the SealMiner A3 Air delivers a hashrate of 260 TH/s while consuming 3,640 W of power. With an efficiency of approximately 14 J/TH, it offers a balanced solution for miners who prioritize energy optimization without compromising computing power.

One of the standout features of the SealMiner A3 Air is its advanced air-cooling system. Equipped with optimized fan structures and a well-engineered chassis, it ensures consistent thermal performance even under continuous high-load operation. This design not only improves the durability of the hardware but also allows the machine to function effectively in a wide range of environments. With an operating temperature tolerance of -20°C to 45°C and humidity support up to 95%, the SealMiner A3 Air adapts easily to diverse deployment conditions.

Noise control is another strength of the SealMiner A3 Air. Its design produces less noise compared to many conventional miners, with reports showing it operates at around 3–4 dB quieter than typical air-cooled models. This feature reduces the acoustic footprint of mining operations, making it more suitable for installations where sound management is important. Combined with efficient airflow, this results in a smoother and more stable mining process.

The SealMiner A3 Air is also built with high-efficiency power delivery in mind. It integrates a power supply system capable of maximizing energy conversion, reducing waste, and ensuring consistent delivery of stable power to the machine’s ASIC chips. This makes long-term operation more reliable and cost-effective, particularly in energy-sensitive mining farms. Its sturdy build and streamlined design further contribute to lower maintenance needs and better overall performance.

From a usability perspective, the SealMiner A3 Air is straightforward to deploy. With a plug-and-play Ethernet connection and compact body dimensions, it is designed to be easy to install, scale, and integrate into both small and large mining farms. The simplified infrastructure requirements of air cooling mean there is no need for specialized setups such as liquid cooling systems, making the machine attractive to operators seeking a balance of performance and convenience.

Another strength lies in its long-term reliability. The SealMiner A3 Air is backed by Bitdeer’s extensive R&D capabilities and expertise in chip design, ensuring stable operation under continuous workloads. By leveraging Bitdeer’s global presence and technical support infrastructure, users can expect timely firmware updates and professional after-sales assistance, which adds significant value for serious mining operations.

In summary, the SealMiner A3 Air delivers powerful performance with a hashrate of 260 TH/s, energy efficiency at 14 J/TH, and a carefully engineered air-cooling system that ensures consistent, stable operation. Its reduced noise, wide environmental adaptability, efficient power supply, and ease of deployment make it an ideal choice for mining operators looking for a reliable, high-efficiency air-cooled solution. As part of Bitdeer’s SEALMINER lineup, the A3 Air stands out as a robust and forward-looking mining machine, designed to support profitable and sustainable Bitcoin mining in 2025 and beyond.

Specifications of SealMiner A3 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.
