Lower Operating Costs

Building a smarter ductwork system.

Optimize the performance of your ducted air quality system with RoboVent DeltaGate. The DeltaGate system controls airflow to each cell individually, so you can reduce airflow and energy needs for your entire system.

DeltaGate delivers:

  • Energy savings: With DeltaGate, airflow for each section is modulated based on welding activity, reducing energy costs by up to 30%-60%, depending on production process cycles. (See chart below.)
  • Automation: The DeltaGate opens automatically when the welding arc is on, so welders don’t need to think about dust control.
  • Flexibility: DeltaGate is part of a modular ductwork system, so each gate is easy to move if your configuration needs to change.
  • System efficiency: With DeltaGate, you can do more with less. Because airflow needs are based on actual use rather than number of stations, you’ll need fewer (or smaller) dust collectors overall.

DeltaGate How it works

How It Works

RoboVent Ducted System with DeltaGate Running with 70% of the stations welding:

The RoboVent ducted system illustrated here shows 3 of 11 stations with their DeltaGates closed. The system includes one indoor Fusion Series collector and two outdoor Fusion Series collectors in tandem. With (3) 40 HP motors total, using the data on RoboVent savings seen in the graph, and assuming an average arc-on time of 71%, the total savings per 8-hour shift would be 858.9 KWHs!

AAutoSaver: Automatically modulates extraction with welding activity.

BDeltaGate: Gates controlled by AutoSaver seal off ductwork sections not in use, reducing airflow requirements for the entire system.

CDelta3 Spark Arrestor (option): The proprietary Delta3 spark arrestance system uses centrifugal force to eliminate sparks before they can enter the ductwork.

DeDrive: VFD (Variable Frequency Drive) controls the collector based on sensors that detect airflow requirements across the system as the DeltaGates open and close.

EeTell: The cloud-based eTell smart control system acts as a central hub to automate and optimize performance for the entire system.

FDust collector: DeltaGate can be used with many of RoboVent’s most popular dust collectors, including Spire and Fusion series collectors.

Energy Savings with RoboVent DeltaGate

Arc-on time for most robotic welding stations is between 45% and 75%. For manual stations, arc-on time may only be between 20% and 40%. So why pay for the power to run your dust collection system 100% of the time?

With RoboVent’s automated controls, your system is on when you need it, and off when you don’t—delivering significant energy savings.

The DeltaGate system is tied to welding activity, but it also includes an automated airflow control that adjusts the airflow to meet what is needed for the welding stations in operation.

The proprietary eDrive Automated VFD works with the DeltaGates to control airflow and adjust the motor speed up or down based on system requirements. That means your system draws power only when it is needed—reducing overall airflow and horsepower requirement by an average of 30%.

Built for quality

We build safety, energy savings and efficiency into every piece of equipment we make.


Lower Operating Costs

We're always looking for ways to reduce energy use, such as automated systems to ensure collectors run only when they need to. Additionally, our filters and equipment have been engineered to maximize filter life and reduce operating costs.


Superior Safety and Risk Reduction

Safety features like our Delta3 spark arrestor and the Supprex-200 fire suppression system reduce the risk of fires in your ductwork and filtration equipment to protect your plant and your employees.


Easy Maintenance

Longer lasting filters are just the start. Our equipment is built to reduce the maintenance burden on your staff. With eTell intelligent controls, you can move beyond preventative maintenance to truly predictive maintenance
