Impulse Ventilation FLANGED

introduction JetVent Axial Impulse fans have been specifically designed to provide a high velocity airflow to help overcome problems caused by obstructive structural beams and low overall ceiling heights found in car parks. The innovative design of JetVent Axial Impulse fans provides major benefits in terms of reduced installation and running costs as well as effective smoke control. Technical excellence and innovation in design are the cornerstones of an Elta product - JetVent is no exception to this approach. The harmony of our engineering excellence and technical sophistication combine to...

There are a number of differences between conventional mechanical and impulse ventilation systems, namely; • The distribution ducting used in traditional systems (Figure 2.0) is replaced by a number of small JetVent impulse fans (Figure 3.0) to direct the airflow across the designated area. • Without the distribution duct resistance, smaller exhaust and supply fans and / or motors can be used. The impulse ventilation system is based on a number of small, strategically located high velocity fans in place of the distribution ductwork traditionally used in car parks. Impulse fans operate on well...

no ductwork requirement 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 facilities. By eliminating ductwork, the system resistance for the application is greatly reduced, which means lower pressure drops required by the extract fans, lower power consumption, and reduced running costs. Greater flexibility...

air quality JetVent provides an improvement in air quality achieved by mixing the air more effectively, which means the potential risk of Carbon Monoxide accumulation in stagnant areas is overcome. safety and control A mechanical smoke extract system that is independent from external conditions allows emergency control of the situation by the fan services. The removal of smoke assists the safety of the occupants in the event of a fire. impellers Adjustable pitch aerofoil section impellers provide a long lasting robust construction for ambient and high temperature applications. rigorous testing...

Exhaust Hot Ceiling Jet Fan Zone of Turbulent Mixing Air Inlet Ventilation requirements in order to limit the concentration of Carbon Monoxide and other vehicle emissions in covered car parks and to remove smoke in the event of a fire can be found in the relevant Building Regulations and in BS 7346-7:2006 Components for smoke and heat control systems – Code of practice on functional recommendations and calculation methods for smoke and heat control systems for covered car parks. Elta Fans are a major supplier of axial flow fans for fresh air supply and extract as well as for emergency smoke ventilation...

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 are dynamically balanced to Grade G6.3. silencers An inlet and outlet silencer are mounted either side of the fan housing, with an integral bell mouth to provide reduced sound levels and optimal performance. Silencers are constructed from pre-galvanised sheet...
