By Belmont Fan | 24 Years of Fan Manufacturing Experience
In the evolving world of HVAC engineering, energy efficiency, system redundancy, and compact design are more critical than ever. One innovation leading this transformation is the EC FanGrid — a configuration of multiple EC plug fans operating in parallel within an air handling unit (AHU).
At Belmont Fan, we manufacture high-performance EC centrifugal plug fans tailored for FanGrid applications. With over 24 years of expertise, we support HVAC OEMs and system integrators worldwide with energy-efficient, modular fan solutions.
What is a FanGrid?
A FanGrid is a modular fan wall system where several EC plug fans work together to deliver consistent airflow. Instead of using one large belt-driven fan, FanGrid systems distribute airflow more evenly, reduce noise, and ensure system redundancy — if one fan fails, the rest continue running.
This concept has become the go-to choice for next-generation AHUs, especially in critical applications such as:
Data centers
Hospitals and cleanrooms
Commercial buildings
HVAC retrofits and energy upgrades
Traditional AC belt-driven forward curved fans come with major limitations:
❌ Energy loss due to belt drive
❌ Difficult maintenance
❌ Bulky installation space
❌ Poor efficiency at partial loads
Belmont EC Plug Fans, on the other hand, offer clear advantages:
✅ Direct Drive Efficiency No belts, no pulleys — just direct connection between motor and impeller. This eliminates energy loss and mechanical failure.
✅ Energy Savings up to 50% EC motors adjust speed precisely based on demand (via 0–10V or PWM), consuming only as much energy as needed.
✅ Built-in Redundancy In a FanGrid, each fan operates independently. If one fails, the rest continue without interrupting system performance.
✅ Compact & Modular Design Belmont’s EC centrifugal plug fans are optimized for stacked installation in limited spaces.
✅ Quiet Operation Backward curved impellers and direct drive reduce vibration and noise — ideal for indoor AHU environments.
✅ Smart Control Options Easily integrated with BMS via MODBUS-RTU, 0–10V analog input, or PWM.
