Bitdeer SealMiner A4 Pro Air: 336 TH/s – 3662W – 10.9 J/TH
Launched in April 2026 as part of the SEALMINER A4 series, the Bitdeer SealMiner A4 Pro Air is a high-efficiency SHA-256 ASIC miner purpose-built for Bitcoin (BTC) mining. Delivering up to 336 TH/s at just 3662W with an industry-leading efficiency of 10.9 J/TH, this air-cooled powerhouse sets a new standard for performance-per-watt.
Compared to the previous A3 series (12.5 J/TH), the A4 Pro Air delivers a significant leap in energy efficiency—helping miners reduce power costs while maintaining stable, reliable, and continuous mining performance.
Key Features & Advantages
⚡ 10.9 J/TH Energy Efficiency – Industry-Leading Performance
Built for superior energy utilization, the A4 Pro Air maximizes mining output while actively reducing power consumption. This efficiency breakthrough helps miners achieve more value per watt—directly improving profit margins in both bull and bear markets.
🚀 Up to 336 TH/s High Hashrate
Delivers strong, stable computing power that improves mining efficiency and increases potential returns. Whether you’re running a small-scale operation or a large mining farm, the A4 Pro Air provides the consistent hashing power you need to stay competitive.
🔋 Reliable Power Performance
With high power conversion efficiency and stable voltage support, the A4 Pro Air maintains consistent performance even under continuous high-load operation. No throttling. No instability. Just reliable hashing, 24/7.
❄️ Optimized Air Cooling System
The advanced air-cooled design ensures effective heat dissipation and stable operation across an exceptionally wide temperature range—from -20°C to 50°C. This thermal flexibility enables global deployment in diverse climate conditions without requiring complex liquid cooling infrastructure.
🏭 Built for Long-Term Mining
Designed for durability and operational stability, the A4 Pro Air supports continuous operation around the clock

The Bitdeer SealMiner A4 Pro Air is a high-efficiency, air-cooled ASIC miner for SHA-256 Bitcoin mining, launched on April 7, 2026, by Bitdeer Technologies Group (NASDAQ: BTDR). It occupies the air-cooled position within Bitdeer’s A4 series, running the same SEAL04 proprietary chip as the hydro A4 models (A4 Pro Hydro at 680 TH/s, A4 Ultra Hydro at 886 TH/s at 9.45 J/TH) but in an air-cooled form factor. It is purpose-built for facilities that cannot support liquid cooling infrastructure or three-phase electrical service.
Bitdeer SealMiner A4 Pro Air runs the fourth-generation SEAL04 proprietary chip—the same chip platform as the A4 Pro Hydro and A4 Ultra Hydro. This represents a deliberate product strategy: operators without three-phase power and hydro infrastructure can access current-generation chip architecture without facility CapEx for hydro loops or electrical upgrades. The air-cooled variant trades hashrate per unit (336 TH/s versus 680–886 TH/s on hydro) for deployment simplicity.
The SEAL04 chip generation represents meaningful efficiency progression within Bitdeer’s air-cooled lineup :
| Generation | Series | Efficiency Range |
|---|---|---|
| Gen 1 | SealMiner A1 | 30+ J/TH |
| Gen 2 | SealMiner A2 Air | 19–22 J/TH |
| Gen 3 | SealMiner A3 Air | 12.5–14 J/TH |
| Gen 4 | SealMiner A4 Pro Air | 10.9 J/TH |
Compared to the A3 Air generation, the A4 Pro Air delivers approximately 13% better efficiency per terahash . Compared to the A3 Pro Air predecessor (290 TH/s at 12.5 J/TH), the A4 Pro Air delivers 46 TH/s more hashrate with approximately 13% better efficiency.
As an SHA-256 ASIC, it can mine all SHA-256 algorithm cryptocurrencies, including :
-
Bitcoin (BTC) – Primary target
-
Bitcoin Cash (BCH)
-
Bitcoin SV (BSV)
Competitive air-cooled landscape at the 300–350 TH/s tier :
| Model | Hash Rate | Efficiency | Year |
|---|---|---|---|
| Bitdeer A4 Pro Air | 336 TH/s | 10.9 J/TH | 2026 |
| Bitmain Antminer S21 XP | 270 TH/s | 13.5 J/TH | 2025 |
| Bitmain Antminer S23 | 318 TH/s | ~14 J/TH | 2026 |
| Bitmain Antminer S21+ | 235 TH/s | 16 J/TH | 2025 |
| Whatsminer M70 | 214 TH/s | 18 J/TH | 2025 |
The A4 Pro Air holds the efficiency lead in current-generation air-cooled Bitcoin hardware, approximately 22% better per terahash than the closest Bitmain air-cooled alternative (S21 XP at 13.5 J/TH) at higher hashrate per unit.
