90cm Negative Pressure Fan | High-Volume Ventilation for Bitcoin Mining Farms and ASIC Datacenter Heat Exhaust
The 90cm Negative Pressure Fan is the industrial-scale ventilation fan for Bitcoin mining farms and ASIC datacenter heat exhaust. Pulls air through the room, exhausts the heat outside, and creates the negative pressure differential that drives fresh intake air across the miners — the standard solution for managing the thermal load of a multi-rack mining deployment. 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 16000 CFM / 27000 m³/h airflow, a single fan handles the ventilation for a 110–140 m² mining room. 370W power draw and ≤70 dB noise level are favourable for the volume moved.
When to Install the 90cm Negative Pressure Fan
- Mining room temperature rising above safe operating range — existing ventilation insufficient, miners throttling.
- New mining facility deployment — install at the heat-exhaust wall during build-out, before miners are populated.
- Scaling existing mining operation — additional fans for rooms growing past their original ventilation capacity.
- 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 — 90cm Negative Pressure Fan
Q: How many fans do I need for a given mining room size?
A: One 90cm fan covers 110–140 m². Larger rooms need multiple fans for proper air exchange. For high-density mining (5+ kW/m²), plan for higher fan counts than the area-based calculation suggests — heat load matters more than floor area.
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.
