High-Power 1220mm Negative Pressure Fan 220V/380V for BTC Crypto Mining Farms

1220mm Negative Pressure Ventilation Fan | Industrial-Scale Heat Exhaust for BTC Crypto Mining Farms and ASIC Datacenter Ventilation (220V / 380V)

The 1220mm Negative Pressure Fan is the largest-volume industrial ventilation fan in our crypto mining farm lineup. Step up from the 900mm and 1000mm classes when room size or heat density crosses what a smaller fan can handle on its own. Pulls air through the room, exhausts the heat outside, and creates the negative pressure differential that drives fresh intake air across the miners. Available in 220V single-phase or 380V three-phase variants to match local facility power.

Built with an anti-rust thick galvanized sheet body and galvanized or stainless steel fan blades for sustained outdoor and high-humidity service. The pure copper motor gives reliable continuous-duty operation. At 22000 CFM / 37000 m³/h airflow, a single fan handles the ventilation for a 160–190 m² mining room — roughly 20% more coverage than the 1000mm variant with about 36% more power draw.

When to Install the 1220mm Negative Pressure Fan

• Large mining rooms over the 1000mm fan's coverage — 160-190 m² rooms benefit from the higher-volume fan vs running multiple smaller units.
• High-density mining deployments — heat load above 5 kW/m² needs higher airflow than smaller fans deliver.
• New mining facility deployment — install at the heat-exhaust wall during build-out before populating racks.
• Replacing a failed industrial fan — old fan motor or bearing dead, immediate replacement to restore room ventilation.
• Container mining or warehouse-scale deployments — pair with intake louvres for the standard hot-aisle / cold-aisle airflow pattern.

FAQ — 1220mm Negative Pressure Fan

Q: When to choose the 1220mm vs the 1000mm or 900mm variant?
A: 1220mm delivers ~25% more CFM (22000 vs 17650) and covers ~20% more floor area (160-190 m² vs 130-160 m²) at ~36% more power (750W vs 550W). For large rooms or warehouse-scale facilities, the 1220mm wins. For mid-size rooms, the 1000mm is more efficient.

Q: 220V vs 380V — which variant for my facility?
A: 220V single-phase for residential or small-commercial facilities; 380V three-phase for industrial facilities with three-phase mains. The 380V variant has slightly better efficiency at scale. Verify your facility's incoming power before ordering.

Q: Indoor or outdoor mounting?
A: The galvanized sheet body handles outdoor mounting (typical for exhaust-wall installations). For full weather exposure, add a hood or louvre cover to protect the fan from direct rain on the intake side.

Q: Bulk pricing for multi-room farm operators?
A: Yes — email contact@lys-sz.com with your facility size and we'll send case-quantity pricing.
