Power Master VFD: Ecogate's Variable Frequency Drive

Ecogate Power Master Variable Frequency Drive (VFD) automatically adjusts the speed of the motor on your industrial ventilation system's fan while significantly reducing electricity consumption. Our VFD was developed in collaboration with industry-leader ABB, based on their top-of-the-line industrial Variable Frequency Drive ACS880 model which comes with the highest reliability, performance, and safety.  


The Power Master VFD Difference

Energy Efficiency for Industrial Ventilation Systems

By incorporating the Power Master VFD into your complete Ecogate system, you will experience the benefits of reduced electricity usage on the fan operation. Save 68% or more on your dust collection costs while enjoying automatic airflow adjustments and an automatic start and stop feature for your dust collector. Eliminate the need for maintenance personnel  to start the system manually before shift, and stop it after shift.

Simple Setup, Easy to Use, and Reliable

The Power Master VFD is designed for easy on-site configuration. The Ecogate Setup Assistant guarantees trouble-free VFD startup within a minute, streamlining installation, setup, and operation for our users. Built with a NEMA-12 dust-proof cabinet, exterior heat sink, industrial air filters, and positive inside pressure, the Power Master VFD is designed for heavy-duty applications, ensuring reliable performance for years to come.


The Automatic, Stop, and Manual mode selector is installed on the front door, along with Enabled, Running, and Error door indicators. Two high-end pressure transmitters are integrated (one for fan pressure, the other for filter pressure). Connecting to the Ecogate greenBOX control unit is simplified by using the Ecogate Master cable (communication occurs via Modbus RS485), compatible with all greenBOX models. Dry contacts for starting and stopping the dust collector on-demand are included, while an OK/Error signal serves as an Enable signal, halting the main fan if any issues arise with the dust collector. The Power Master is available as a wall-mounted NEMA 12 (dust-proof) enclosure for 10 to 200 HP and as a standalone enclosure (NEMA 12 dust-proof) for 250 to 420 HP. Power Master VFD options range from 10 HP to 420 HP, in 120V, 240V, 460V, and 575V variants.

Advanced Connectivity and Control

Monitor your VFD status in real-time through the greenBOX or remotely, ensuring you always have access to vital information. With features such as Modbus communication, backup power supply for the VFD processor, and monitoring of critical VFD components, the Power Master VFD offers unparalleled connectivity and control. 

Why a VFD Alone is Not Enough

While VFDs can help reduce energy consumption, using a VFD alone is not sufficient to ensure the safe operation of a fume extraction or dust collection system. Slowing down the fan without use of the Ecogate system leads to reduced air volume and suction at all machines, potentially causing dust settling or even fires.


To reduce the electricity usage of a dust collection system safely, it is crucial to direct airflow where it is needed using automatic blast gates and an intelligent control system.
