The challenge of creating comfortable living spaces in apartments is made easier with a range of products from Fantech.

It is important to consider our customer’s needs in a more holistic manner than has been customary, and recognise that every litre of air flow is critical in these compact systems.

We recognise that space is very limited in apartment design so we have created a range of products that require very little head room but also maximise air flow and minimise noise.

As the primary component of the system, the fan needs to be slimline without any compromise in efficiency. Fantech’s JetStream and Mixvent series fit these criteria.

One of the prime design objectives for the JetStream series was to produce a slimline fan that was quieter than similar products on the market.

Computerised fluid dynamics (CFD) analysis was used to design the ultra slim housing and optimise aerodynamic performance. We have been able to reduce the required headroom to 235 millimetres for the JCE152 and 268mm for the 202 models. In addition, the aerodynamic design means the fan has exceptional air flow and impressive acoustic performance.

Energy consumption has also been considered. The single speed JCE152-1 can be speed controlled while the JCE152-3 and JCE202-3 models are three-speed. In most installations it is not necessary for the fan to be operating at maximum capacity all the time. Speed control can reduce power consumption and provide a more desired air flow.

Like the JetStream series, the Mixvent series includes a range of very compact fans.

The two-speed TD-500/150 model requires only 200mm headroom and delivers air volumes of up to 140 litres per second (500m³/h) which is powerful enough to cope with extensive duct systems.

Specially designed support brackets in the Mixvent series enable the fan to be removed for cleaning etc., without disturbing the connecting ductwork. The series is also very flexible, with fans able to be installed as single–stage fans or arranged in parallel, in series or both parallel and series to enable higher air flow and pressure demands to be met, without compromising head height.

A revolutionary low-pressure backdraft damper has been developed for use with any of the fans in the apartment ventilation system. The patented Smooth Flow damper ensures optimum performance from the fan, with the resistance to air flow being a fraction of spring-loaded butterfly types.

New to the Fantech range is the JetStream ‘Y’ piece that divides air flow. It is made from injected-moulded ABS flame retardant material and has a smooth surface to minimise resistance. The ‘Y’ piece is made from two parts which makes it easy to transport and store before installation. It fits directly onto the JetStream 152 in-line fans, the S&P TD-500/150 Mixvent fan, the Smooth Flow backdraft damper and standard 150mm flexible duct.

Fantech also supplies grilles, shutters and louvres, attenuators, run-on timers, duct adaptors and speed controllers to complete the apartment ventilation package.
