The Elta Fans SmokeVent range
has been specifically developed for
emergency smoke extract
We are a major supplier of axial flow fans for smoke ventilation in Ireland. The standard range can operate as part of the main extract system, or as fans for emergency clearance in hazardous fire, smoke and fume conditions.
All casing parts are heavy gauge mild steel sheet, roll formed and welded, then hot dip galvanised to BS EN ISO 1461 after fabrication to provide a long lasting and robust construction. Flanges are roll formed as part of the casing. Motors and axial impeller are mounted within the length of the unit casing.
Motors are totally enclosed metric type to IP55, with sealed for life bearings below 160 frame. Standard industrial paint finish and class H insulation to EN 60034-5, suitable for use at normal continuous duty and a once only use under smoke operation at 200°C, 300°C and 400°C for 2 hours. Flying leads are brought out via a temperature resistant conduit system, to an external IP55 terminal box for customer cabling interface.
Adjustable pitch aerofoil impellers are provided with blades made from high quality aluminium (LM6) natural finish. Impellers are factory set at an angle to exact customer requirement. The hubs are manufactured from die cast aluminium alloy (LM6 or LM24). Assembled impellers are dynamically balanced to ISO 14694.
Units are certified to EN12101-3 and LPCB third party certified. Units are designed and manufactured with procedures as defined in BS EN ISO 9001. Units are tested to ISO 5801:2007 (airside performance) and BS 848 Part 2:1985 (sound performance).
Axial and Centrifugal fans
for both general ventilation
and emergency situations
The Elta Fans JetVent range includes induction and impulse ventilation models developed to operate as both general ventilation and for once-only, emergency extract mode at temperatures of up to +400°C.
Features and Benefits
The elimination or reduction in ductwork means a safer, lighter environment with better security due to the increased visibility.
By adding momentum to the air, JetVent thrusts air towards the desired extract points to ensure stagnant fumes and smoke are cleared effectively and efficiently. This principal eliminates the requirement for ductwork within a car park, as the JetVent effectively transfers the polluted air, allowing for better use of limited space in underground facilties.
The integral bell mouth inlet has a streamlined appearance for improved performance and sound.
With no ductwork, maintenance costs are reduced as there is no ducting to become blocked, damaged or subject to leakage.
JetVent provides the scope for reduced installation and overall construction build costs compared with traditional ducted systems. The high efficiency impeller make this a very economical method of moving high volumes of air.
JetVent axial fans are of a robust, heavy duty construction for added strength and durability. Fan casing are heavy gauge, sheet steel, roll formed and welded and hot dipped galvanised after fabrication to BS EN ISO 1461.
