Name: Jet fans
Availability: InStock

Induction jet fans, unidirectional and reversible, that move air by momentum transfer instead of by ducting it. Supplied in circular and low-profile rectangular casings with EN 12101-3 high-temperature certification, typically 300 °C or 400 °C for 120 minutes, so the same units serve the smoke case.

Replace the extract ductwork in car parks: main extract and supply fans sit at the ends of the level and jet fans push the air across the slab, freeing the soffit and buying back headroom on every floor. The same array serves double duty — daily CO/CO₂-controlled ventilation and, on a fire signal, smoke clearance under a CFD-verified control strategy that has to be modelled for the actual geometry, not adopted from another project.
