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 is an important part of returning clean air back into a facility.
Raptor Spark detection, thermal probes and dust probes activate the Raptor Single Zone or CU1610 multi-zone control panels in the event of a fire or filter failure in the dust collector.

The Raptor Gate can be located on the return air side to redirect contaminated air, sparks or fires. It does not protect the system from explosions.

Added benefits of the Raptor Gate:

Terminals to interlock with Raptor Spark detection system for activation
10 gauge carbon steel construction and precise, strong welds ensure the most durable product
Manual reset type with hand-crank actuator. Push button reset type with electric assist
Electromagnets are fail-safe and use gate accelerating springs for the fastest gate closure
Meets all NFPA standards, including NFPA 652 and industry-specific standards
All abort gates tested prior to shipment for superior performance

Heavy Duty and spring loaded with fully welded 10-gauge carbon steel construction
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
Available Sizes 4” (400 CFM) through 72” (87,500 CFM)
115-volt AC Control Panel

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.
