Automatic Blast gates



Whether you searched for an Eco-gate, a blastgate, automatic gate, or a damper we have the gates. Our fully automatic blast gates are a key component of an Ecogate System, continuously opening automatically to machines that need exhaust ventilation and closing to machines that do not need any. 


The automation is quite simple: when the machine’s cutting tool turns on, blast gates open to achieve designed suction. They stay open until the machine no longer needs suction, at which point the machine’s gate closes. When your dust collector turns on, blast gates open automatically. When the dust collector powers down, the entire system powers down with it, reducing wear and tear as well as electricity consumption. 


This results in dust (fume, mist) collection that provides electricity savings, better suction, reliability, performance, and safety. 

Ecogate Smart Gates

Operated by 24V DC motor, with embedded processor to read pressure, air velocity, and air volume and Modbus communication. The gates are available with a rotating blade or butterfly; zinc plated metal or stainless steel. These are the most robust, advanced, and cost-effective gates on the market. The gates are available from 2” up to 26” duct diameters. Ecogate gates have open and close limit switches that are reported to control unit greenBOX and to users. You do not need to guess if the gate is open or closed.

Efficient & Cost-Effective

Ecogate's electronic blast gates outperform pneumatic blast gates in both efficiency and cost. By eliminating the need for compressed air, our gates simplify installation and significantly reduce electricity costs throughout the system's life cycle. 

Industrial-Grade Performance

Our industrial-grade blast gates are trusted by factories worldwide, with tens of thousands in operation across various industries. Duct systems are heavy, creating a lot of force on gate bodies. The only solution is to install robust gates to ensure reliability. Available in zinc plated or stainless steel, you can rest assured that you're investing in high-quality rather than inexpensive alternatives. 

Real-Time Airflow Monitoring

Ecogate's patented next-generation Smart Gate is the world's only automatic blast gate that continually monitors air flow in its duct. This real-time insight allows for maximum electricity savings and guarantees transport velocities are maintained throughout the duct system.

Guillotine Style Gates (With Rotating Blade)


Perfect for a wide range of industrial applications, our Guillotine-Style Gates allows for reliable and efficient dust collection. These heavy-duty, patented rotating blade gates are suitable for dust collecting systems in woodworking and other industrial dust applications where a lot of material is transported in airstream. The gates are sealed under negative pressure. Each gate is powered by an efficient 24V DC motor and is equipped with Open/Close limit switches for precise operation.

Blast Gate Dimensions


To find the perfect fit for your industrial ventilation system, consult our comprehensive table of blast gate dimensions, available for sizes ranging from 2 to 26 inches. If you are using 3D CAD models for designing your systems we have 3D models of all gates available in STEP and 3D PDF file formats. Click the PDF icon for detailed information. 

Butterfly Style Gates

Butterfly Gate

Ecogate's Butterfly-Style Gates cater to specialized applications where Guillotine-Style Gates may not be suitable. Featuring a rotating blade with a silicone seal, these gates provide an airtight closure when shut. Compatible with both positive and negative pressure environments, Butterfly-Style Gates are ideal for fume or mist applications, such as welding, chemical fumes, and mist oil, as well as those involving small amounts of fine dust, like in pharmaceutical production and food packaging. They can also be used for fine metal dust, thanks to the external placement of magnetic limit switches.

Standalone Gates for Small Shops


Need one blast gate for your dust collection system? Our Standalone Blast Gates by Ecogate offer an easy and cost-effective way to manage airflow at a few machines in your industrial system. The gate is designed to be connected to a 24V DC power supply and a workstation activity sensor, or alternatively, the gate can be operated for opening and closing using any dry contact (switch, relay, PLC) or with simple timers or switches for machines lacking an electrical panel


A couple of Standalone Gates could be more affordable than a full control system while maintaining automation benefits. They are designed to be versatile and durable, accommodating various applications with guillotine or butterfly styles. Upgrading to a complete system is easy, requiring only a motor replacement.
