What is a fandeck?

Swoosh Image

Simply put, a Fandeck is a tandem of fans. You may have come across our fandeck range on our website or perhaps you’ve spotted the word whilst browsing the internet, but what exactly is it? And how does it work? This blog will answer those key questions.

What does a Fandeck consist of?

A Fandeck in essence, is an assembly of centrifugal fans using a single motor to drive them through a common shaft, mounted on a base or `deckplate’.  Fandecks can also consist of multiple DIDW (Double Inlet, Double Width) an array of pod blowers or ‘pod’ fans as they are commonly termed attached to a deck plate, with each blower having its own drive motor (either AC or EC motor technology).

How does it work?

A Fandeck works in much the same way as a single centrifugal blower unit, but as there is typically more than one blower mounted in parallel, the flow rate delivered from these products is approximately multiplied by the amount of blowers attached to the deck plate. Moving a single motor to drive the blowers delivers market leading efficiency as well as offering a more cost effective solution for mounting individual blowers with independent motors. It also means that each blower provides a balanced airflow.

For EC Fandeck models, the motors operate in constant speed mode, maintaining a fixed speed based on the control voltage input. Variants of EC Fandecks include versions with two separate motors (for example driving four blower units in total), with this arrangement the control connections are linked together so that only one speed control input signal is required.  EC Fandecks incorporating multiple pod blowers will typically have the control interfaces linked together in a daisy-chain arrangement so that only one control input signal is required. Pod based Fandecks configured in this way may also require an additional EMC filter to reduce conducted and radiated emissions – which can add further to the overall cost.

What applications are Fandecks used for?

Fandecks are typically used in applications requiring a high level of airflow output at a relatively low system pressure. The main applications include air-curtains and fancoils. Air-Curtains are typically used to create a barrier of air that prevents the loss of heat, for example when placed above doorways in retail outlets or in logistic warehouses. Fancoils are typically used for air conditioning as well as other heating and refrigeration applications.

Advantages of a Fandeck

A Fandeck can benefit from using one motor to drive multiple fans at the same time. This has the advantage of bring more reliable and cheaper because there are fewer parts go into the product and fewer parts to go wrong.  A single motor can drive up to three blowers – known as a triple deck. A quad is normally two double Fandecks mounted on a common plate
