JET FAN - Axial
JET FAN - Axial
AREM's JFA is a compact axial fan designed for car park ventilation, optimized for low profile installations. It includes sound attenuators at the air inlet and outlet to minimize noise. The fan is constructed from pre-galvanized steel and features thermal and sound insulation. It offers direct transmission with motors available in one or two speeds. The attenuator also provides thermal and sound insulation and is available in three diameters and two temperature classes (400°C/2h and 300°C/2h). The JFA range covers thrust from 20N to 60N, with models JFA-S, JFA-M, and JFA-L.
The technical specifications include motor speed, nominal thrust, installed power, maximal amperage, maximal flow rate, max air velocity, sound pressure, and maximal weight for each model (JFA-S, JFA-M, JFA-L). For example, the JFA-S model operates at 2810/1410 rpm with a nominal thrust of 20/5 N and installed power of 1.1/0.3 kW.
The JFA range is designed for fire environments, primarily used in car park ventilation to efficiently direct smoke towards extract vents. The high velocity of the air jet aids in smoke evacuation, facilitating emergency operations. Accessories available include custom fan supports, inlet bell-mouths, air deflectors, and switch disconnectors.
The JFA is tested to EN 12101-3 2015 standards and is CE certified. In comfort mode, it can ventilate areas and reduce pollutants from vehicles.
Dimensions for each model are provided, with the JFA-S having a diameter of 315mm and other specific measurements for installation.

APPLICATIONS JFA is the AREM's air impulse axial fan designed to work in fire environment. It is mainly used in car park ventilation to direct and drag efficiently the smoke to the direction of the extract vents. The high velocity developed by the air jet improves smoke evacuation and make the emergency operation easier. In « comfort » mode, AREM's JFA can be used for ventilating the area and lowering the level of pollutants released by cars or other engines. AREM's JFA is a slim and compact axial fan. The product concept is studied for low profile car park height. The attenuators are included to the air inlet and outlet of the fan to optimize sound attenuation: • Fan construction in pre-galvanized steel • Thermal and sound insulation. • Direct transmission • Motors available: 1 or 2 speeds Attenuator It is Available in 3 diameters and 2 classes of temperature • Thermal and sound insulation (400°C/2h and 300°C/2h), AREM's JFA range covers thrust *Do not design overload protection system to the limit of indicated values. Allow an adjustment to compensate the electrical network fluctuations. • **Fully reversible SMOKE EXTRACT ACCESSOIRIES / OPTIONS Accessories are available to accommodate to particular needs and specific installations on field: • Custom made of fan support • Inlet bell-mouth • Switch disconnector or terminal junction box ► TECHNICAL AND SPECIFIC REQUEST ► CFD case of study (fluid simulation analysis) AREM - ZI, chemin des aisieres - 45500 Saint-Brisson sur Loire - Tel. : +33 238 367 105 - Email : info@
