Underground Car Park Ventilation — Jet Fan Systems, F400 Smoke Extraction and CO Sensors

Underground car parks are among Romania's most regulated spaces: normative NP 127:2009, complemented by NP 24-2022 and P118-1:2025, mandatorily requires mechanical forced ventilation with two distinct functions — normal anti-CO ventilation (daily operation) and emergency smoke extraction in case of fire at 300–400°C for 120 minutes.

Anti-CO ventilation: carbon monoxide emitted by combustion engines accumulates rapidly in enclosed spaces. STAS 12574 requires maximum 50 ppm CO continuous and 100 ppm short-term. CO sensors on ventilation.ro (HVAC Control category) automatically activate the ventilation system when the threshold is exceeded.

The Jet Fan system — the modern ductwork-free solution: ceiling-mounted impulse fans create through the Coandă effect an organised flow transporting CO and smoke to final extraction outlets, completely eliminating the need for a distribution duct network. Advantages over the traditional duct system: 30–40% lower initial investment, faster installation, simpler maintenance.

Axial Jet Fans JF 300 T2/T4 on ventilation.ro with integrated acoustic attenuators, F300/120 certified per EN 12101-3.

Low Profile centrifugal Jet Fans for car parks with clear height below 2.2 m. F400/120 final extraction fans for mounting outside the hazardous zone.

Important: Jet Fan system sizing must be validated through a mandatory CFD study (SR CEN/TR 12101-5) — the only method demonstrating smoke evacuation compliance that ISU accepts for approval.

JET fans - JF 300 T2 UN CONFORT

Casals JF 300 T2 UN CONFORT — unidirectional axial jet fan designed for polluted air (CO, CO₂) and accidental fire smoke evacuation in underground car parks and large spaces, in compliance with normative NP 24-2022.

Maximum airflow 4,500 m³/h, thrust force 26 N, three-phase motor 0.55 kW, 2,780 rpm, current 1.36A / 400V, protection IP55, insulation Class F, maximum operating temperature 60°C.

Composed of an axial fan with galvanised steel casing flanked by 2 mineral wool silencers — significant acoustic attenuation versus non-silenced jet fans.
