AXAIR FANS
ECFanGrid solution with Axair Fans
Continuous and consistent airflow is essential in most facilities , making under-performing or unreliable fans simply unacceptable . In addition to reliability concerns , inefficient fans can be a buildings biggest energy consumer . We learn more about the ECFanGrid solution with Axair Fans .
WHAT IS AN ECFANGRID ?
An ECFanGrid is a simple , complete kit of parts for new or existing AHU ventilation units . Quite simply it is a multiple fan array in which fans run in parallel . This offers great advantages over old belt driven systems .
HOW ARE THE RIGHT EC PLUG FANS SELECTED FOR EACH ECFANGRID PROJECT ?
We ’ ll complete a detailed site survey that enables us to calculate the current plant efficiency , determines spacing , accessibility and other feasibility checks . We ’ ll use our technologically advanced fan selection software to assist us in choosing the right plug fan type . The software offers multiple ECFanGrid solutions that can be optimised for cost , efficiency , or redundancy . We ’ ll use this data along with our own expertise to choose the right configuration for your project .

WHAT IS INCLUDED IN AN ECFANGRID KIT ?
The ECFanGrid is delivered as a complete kit of parts , this includes all mechanical parts such as fans , cabinet , grid and screws . Whether you choose to install yourselves , have external contractors or utilise our ECFanGrid install team , your installation will be fast and effective with very little downtime .
WHAT TYPE OF FAN IS USED IN AN ECFANGRID ?
Energy efficient EC plug fans are chosen to meet the requirements of each ventilation system . We ’ ll advise on the type of plug fan best suited dependent on your project aims and system duties .
WHAT ARE THE BENEFITS OF RUNNING FANS IN MULTIPLE ?
In short , by running fans in parallel , the benefits are improved reliability , flexibility , and efficiency .
WHAT IS THE RETURN-ON-INVESTMENT PERIOD IF WE INSTALL AN ECFANGRID ?
From the data we obtained during site surveys or those that you ’ ve given to us , we ’ ll calculate the payback period to allow you to make an informed decision about your project . On average the typical ROI period of a retrofit FanGrid project is 2-5 years .
HOW DO YOU CALCULATE THE PAYBACK PERIOD ?
To accurately calculate the payback period of an ECFanGrid , it ’ s a simple case of comparing the absorbed power for the existing system against the absorbed power for the ECFanGrid .
To do this , a validation survey is undertaken , and the volume flow rate and total static pressure of the existing fan is measured . The absorbed power of the fan system is simultaneously recorded . This data is then compared to the absorbed power figures
