Induction Ventilation

introduction JetVent Centrifugal Induction fans have been specifically designed to provide a high velocity, laminar airflow in a reduced height profile to help overcome problems caused by obstructive structural beams and low overall ceiling heights found in car parks. The innovative design of JetVent Centrifugal Induction fans provides major benefits in terms of reduced installation and running costs as well as effective smoke and contaminant removal. JetVent - the principle The induction ventilation system is based on a number of small, strategically located high velocity fans in place of the...

There are a number of differences between the conventional mechanical and modern induction ventilation systems, namely; Figure 2.0 Conventional ducted system Figure 3.0 Equivalent induction system layout raditional Ducting Exhaust Point a) The distribution ducting used in traditional systems (Figure 2.0) is replaced by a number of small JetVent Centrifugal nduction fans (Figure 3.0) to direct the airflow across the designated...

features & benefits The JetVent Centrifugal Induction fan range comprises two standard sizes, 50N and 100N, both with uni-directional airflow. no ductwork requirement By adding momentum to the air, JetVent forces air towards the desired extract points to ensure stagnant fumes and smoke are cleared effectively and efficiently. This principal can minimise or even totally eliminate the requirement for ductwork within a car park. As the JetVent effectively transfers the polluted air towards the point of exhaust which means better use of limited space in underground facilities. By eliminating ductwork,...

better security The elimination or reduction in ductwork means a safer, lighter environment with better security due to the increased visibility for CCTV cameras. rigorous testing JetVent is independently tested to meet the exacting standards of EN 12101 – 3:2002 for operating at 300°C for 2 hours. Performance is tested to BS848 – 10:1999 Fans for general purposes - Performance testing of jet fans. air quality JetVent provides an improvement in air quality achieved by mixing the air more effectively, which means the potential risk of contaminant accumulation (beyond specific requirements) is...
