Air Operated Barrier Gate – Air Operated Boom Gate with Zero Electrical Components
The MB832-PA Air Operated Barrier Gate is the only true air-powered boom gate that needs no electricity whatsoever. Powered entirely by a single compressed-air cylinder, this air operated boom gate delivers smooth, reliable operation in explosive environments, remote locations, oil fields, mining sites, or any area where electrical power is unavailable or unsafe. Whether you call it an air operated barrier gate or an air operated boom gate, the result is the same: safe, spark-free access control with arms up to 32 ft long. Install it permanently on concrete or temporarily on movable bases — it works either way. No motors, no wiring, no batteries, no solar panels required.
How the Air Operated Barrier Gate Works
Unlike electric or hydraulic gates, this air operated boom gate uses simple compressed air (40–100 psi) delivered through 1/4″ lines. One-line or two-line configurations give you complete control: pressurize to raise the arm and hold it open, release or reverse pressure to lower it gently. Built-in needle valves let you fine-tune speed and cushioning on site so the arm never slams. The entire system is designed for explosive-sensitive areas because there are zero electrical components — making it the safest choice when electricity isn’t used.
When do you need an arm support? A Boom Tip Support or Bolt Down Cradle is needed for arms over 18 ft long.
Why Choose This Air Operated Boom Gate?:
Engineered for the toughest conditions, the MB832-PA gives you structural steel construction, stainless and galvanized hardware, and a powder-coated orange finish that lasts for decades. The arm is pre-balanced at the factory with three different counterweight options so you can run arms from 8 ft all the way to 32 ft. Add the optional tip support cradle for anything over 18 ft and you eliminate bounce and sag completely. Because it runs on ordinary shop air or a small compressor, installation is lightning fast — often same-day. No permits for electrical work, no trenching for conduit, no worry about power outages. That makes it the perfect hybrid between a fully manual barrier gate and an expensive electric automatic gate.
