The JetVent ULH (Ultra Low Height) car park EC fan is designed to clear harmful pollutants from enclosed and semi-enclosed spaces. They feature a compact overall size and a very narrow height, which may enable the car park’s floor to ceiling dimensions to be reduced.

The Low Profile JetVent comes as a much more compact, single phase unit with mixed-flow ‘Ultra’ impeller, has been designed to be quieter and has a pre-set speed thrust rating of 18.9 Newtons.

Features

• The ULH JetVent is a single phase EC model
• An energy efficient ventilation system that provides the ventilation rate according to the CO or NOx pollutant levels in the space.
• Available with a factory fitted and fully integrated smoke detection kit mounted to the side of the JetVent fan.
• Additional decentralised smoke detectors can be connected to the JetVent system based on car park layout.
• Utilises Aviator controls to digitally connect JetVent fans, Supply & Exhaust fans, Sensors and the BMS together.
• Aviator controls with propriety ComLink system provides a simple control wiring scheme with easy installation, fast commissioning and a high level of system monitoring.
• EC motor features reverse polarity protection, locked rotor protection and soft starting.
• EC motor technology eliminates the need for external VSDs, current overloads and motor phase protection.

Construction
Low-profile galvanised steel housing with aerodynamically designed internal flow elements.

"Fans for general purpose - Performance testing of jet fans."
Noise data based on tests to BS848:Part 2,1985.

Special Note
In most cases Jet fans will be treated as a mechanical performance solution within the National Construction Code (NCC) (formally the BCA). Where required, a mechanical performance solution should comply with the AFAC Guideline 1.0 on Fire Safety for impulse (Jet) fans in Car Parks, and be approved by the appropriate authority. The mechanical performance solution should contain a pollutant analysis and detailed justification to demonstrate the jet fan system will not have a significant detrimental effect on the safe egress of occupants or operation of the sprinkler system.

The high velocity jet fans shall be of the low height JetVent JIU-CPCEC Series as designed and manufactured by Fantech Pty Ltd and be of the model numbers shown on the schedule/drawings. The impellers must be driven by EC external rotor motors with integrated EC-Controller and integral thermal overload protection. They shall be pre-configured to suit CO/NOx sensors and the required applications.

The housing shall be of galvanised steel with a light grey powder coated finish as standard. They shall incorporate mounting feet and aerodynamically designed internal flow elements

Performance data shall be based on tests to BS848:Part 10,1999 for thrust and ISO3744 or ISO13347-3 for noise.
