JetVent: a thrust of fresh air

The release of the new EC (Electronic Commutation) series of Fantech JetVent fans has thrust forward energy efficiency in car park ventilation.

The brushless DC technology used in the EC motor is highly efficient, says Fantech’s Market Development Engineer, Daniel Tan.

“When combined with integrated speed control it can reduce noise and lead to massive power savings,” says Mr Tan.

When performing within AS2107:2000 noise requirements, the fan has the greatest thrust of all similarly sized JetVent fan units. At high speed (25.8r/s), the installed EC fan has a throw distance of 55m.

Mr Tan says there is an increased trend towards demand-based operations to maximise efficiency. 

“Demand Control Ventilation is a smart technology where the ventilation rate matches the demand requirements at any given time,” he says.

“Sensors in the car park measure the level of carbon monoxide and provide feedback to the Digital Zone Controller which automatically adjusts the speed of the fan to ensure carbon monoxide levels remain at an acceptable level.

“Traditionally this has been achieved with an external fan controller and a variable speed drive. Where the JetVent EC differs, is that the speed control is incorporated into the product.”

The EC fan also has a unique feature called ComLink, which allows digital communication between fan units and the matching Digital JetVent Zone Controller.

As a result the wiring schemes used to control the fan are very simple and can therefore lead to huge installation savings. The digital communication also allows real time information to be transmitted back to the central monitoring system.

In addition to the high efficiency motor and speed control of the new EC units, the entire JetVent range utilises small, high speed fans which are more efficient than those used to push air around traditional ducts.

The impulse fans are strategically located and thrust a high speed jet of air which in turn causes movement of large volumes of air through a process known as entrainment.

“The modern trend is to move away from mechanical ductwork and associated constraints,” says Mr Tan.

“At only 365mm high, the JIU-CPCEC fits in most voids and provides the ultimate in car park ventilation efficiency.”
