1100mm Negative Pressure Ventilation Fan | Industrial-Scale Heat Exhaust for BTC Crypto Mining Farms and ASIC Datacenter Ventilation (220V / 380V)
The 1100mm Negative Pressure Fan sits between the 1000mm and 1220mm classes in our crypto mining farm ventilation lineup — the right pick for rooms in the 150-180 m² range where the 1000mm is undersized and the 1220mm is overkill. 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 for sustained outdoor and high-humidity service typical of mining farm exhaust-wall installations. Delivers 20000 CFM / 34000 m³/h airflow at 550W power draw. The intermediate 110×110×35cm form factor fits standard exhaust-wall apertures designed for 1100mm-class fans without custom carpentry.
When to Install the 1100mm Negative Pressure Fan
- Mid-size mining rooms (150-180 m²) — sweet spot between 1000mm coverage and 1220mm overkill.
- Standard mining farm density — heat load typical of fleet-grade ASIC deployments without high-density immersion.
- New 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 — 1100mm Negative Pressure Fan
Q: When to choose the 1100mm vs the 1000mm or 1220mm variant?
A: 1100mm covers 150-180 m² at 550W. 1000mm covers 130-160 m² at 550W. 1220mm covers 160-190 m² at 750W. If your room is in the 150-180 m² range, 1100mm is more efficient than oversizing to 1220mm. For >180 m² rooms, step up to 1220mm.
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. 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.
