Impulse Ventilation

introduction JetVent Axial Impulse fans have been specifically designed to provide a high velocity airflow to help overcome problems caused in part by obstructive structural beams and the low overall ceiling heights found in car parks. The innovative design of the JetVent Axial Impulse fan has been proven to provide major benefits in terms of reduced installation and running costs as well as effective smoke and contaminant movement. excellent performance and safety Technical excellence and innovation in application of our equipment are the cornerstones of any Elta product - JetVent is no exception...

JetVent: the principle The impulse ventilation system is based on a number of small, strategically located high velocity fans in place of the large and expensive distribution ductwork traditionally used in car parks. reduced need for, or complete elimination of the large, expensive ducting, the resulting reduction in system resistance means the exhaust fans are typically smaller and consume less energy. Impulse fans operate on well proven tunnel ventilation principles, producing a high velocity jet which adds momentum to the air in front of the fan imparting thrust to all the surrounding air...

features & benefits The JetVent Axial Impulse fan range comprises several standard and non-standard sizes. They are provided with either uni-directional or truly reversible airflow, as well as a number of optional ancillaries. JetVent can run in either normal extract mode or at a once only smoke operation at 300ºC for 2 hours which means cost savings as a single fan provides both general and smoke extract requirements. design appeal By adding momentum to the air, JetVent thrusts air towards the desired extract points to ensure contaminant laden air and smoke are cleared effectively and efficiently....

specification The JetVent Axial Impulse range comprises multiple thrust types, suitable for ambient temperature operation (at 40ºC) plus a one off operation at 200ºC or 300ºC for 2 hour high temperature smoke conditions to European Standard EN12101–3:2002. impeller Adjustable pitch aerofoil section impellers are provided with blades made from high quality pressure die cast aluminium alloy (LM6). Hubs are made from pressure die cast aluminium (LM24). The assembled impellers have their blades positively locked by pinning, which provides added security for operation in the smoke regime. Impellers...
