Raptor Gate™ Heavy Duty High Speed Abort Gate

Product codes: 56703

Applications

The Raptor Gate™ Heavy Duty High Speed Abort Gate is an NFPA- required safety device to prevent damage from sparks, fire or filter leaks.

The Raptor Gate prevents a flame or burning ember from entering the dust collector.
A spark detector or broken bag detector can trigger the Raptor Gate. If extinguishment from a spark detection system isn’t a good option, an abort gate will vent fire or sparks safely.

Leak detection or broken bag sensors can activate the Raptor Gate if they detect a leak in the filters. This prevents harmful material from traveling back into the building.
The Raptor Gate can be located on the return air side to redirect contaminated air.
Under some circumstances the abort gate can be located prior to the inlet of a dust collection system.

The Raptor Gate™ Heavy Duty High Speed Abort Gate redirects sparks, fires, or contaminated air. It does not protect the system from explosions.

Added benefits of the Raptor Gate:

10 gauge carbon steel construction and precise, strong welds ensure the most durable product
Electromagnets are fail-safe and use gate accelerating springs for the fastest gate closure
All abort gates tested prior to shipment for superior performance
Gates are removable and have steel gate seals
Gates reset with hand-crank actuator, with electric reset as an available option
Optional benefits include weather hoods, support structure, and ladder and service platform
Standard safety yellow powder coating (custom colors available)
Meets all NFPA standards, including NFPA 652 and industry-specific standards

Heavy duty and spring loaded with thicker walls and sturdier construction than the High Speed Abort Gate EM-HSAG02.
Linear actuator gate operation, indicator lights to monitor the system, manual test button, terminals to interlock with Raptor Spark detection system for activation, flanged inlet and outlet, and weather hood with bird screen.
Available in sizes 4” to 60”

Frequently asked questions

Our Raptor Gate closes in 500 milliseconds (1 second = 1000 milliseconds). NFPA mentions in 654 C.1.2.2, “There is an absolute necessity for a predictable amount of time between the detection of the spark and the actuation of the abort gate.”
The only way to achieve this “high speed” is with our spring assist and our robust “honeycomb” gate design. If you are not using a heavy gate and springs, you do not have a high speed abort gate.

Air velocity feet-per-second divided by 2 (1/2 second) = sensor to abort gate distance in feet. Case and point: If you are running your return air velocity at 3000 FPM your sensor to abort gate distance would be 25’. With the less expensive gates that does not have the heavy gates and spring assist, the sensor to abort distance is closer to 50’ needed. This can be a real problem due to the fact that most people do not have that much distance.

There are a couple of companies making abort gates that are built extremely light. Without all of the spring assist, electromagnetic actuators, hollow honey comb blade and other features, they can be made for much less. Our Raptor Gates are the strongest, heaviest and most reliable on the market. When an 800lb blade is slammed shut in less than a ½ of a second, it is important that the gate be built heavy. Our gates are constructed of ¼” & 3/8” plate with a 2-7/8” shaft.
