1000mm Negative Pressure High Ventilation Fan 220V/380V for Crypto Mining Farm

1000mm Negative Pressure Ventilation Fan | High-Volume Industrial Fan for Crypto Mining Farms and ASIC Datacenter Heat Exhaust (220V / 380V)

The 1000mm Negative Pressure Fan is the industrial-scale ventilation fan for Bitcoin mining farms and ASIC datacenter heat exhaust. One step up from the 900mm class — handles larger rooms or higher heat loads on a single fan. 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 17650 CFM / 30000 m³/h airflow, a single fan handles the ventilation for a 130–160 m² mining room — roughly 20% more coverage than the 900mm variant on similar power.

When to Install the 1000mm Negative Pressure Fan

• Larger mining room over the 900mm fan's coverage — 130-160 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 per square metre 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 deployments — pair with intake louvres for the standard hot-aisle / cold-aisle airflow pattern.

FAQ — 1000mm Negative Pressure Fan

Q: When to choose the 1000mm vs the 900mm variant?
A: The 1000mm delivers ~10% more CFM (17650 vs 16000) and covers ~20% more floor area (130-160 m² vs 110-140 m²) at ~50% more power (550W vs 370W). For larger rooms or higher heat densities, the 1000mm wins. For smaller rooms, the 900mm 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.
