Frequently Asked Questions

How does a spark trap work?

Our spark traps have impingement plates that cause turbulence and direct sparks and embers toward the walls of the spark trap, which knocks them around and causes them to lose heat.

Why do I need a spark trap?

If there’s a danger that a spark could travel through your ductwork and ignite combustible dust or other materials, a spark trap may be an important part of your fire prevention system. If you need to know whether a spark trap will work for your application, contact us and we’ll help you find out.

What size spark trap do I need?

This depends on the size of your ductwork. We manufacture to fit almost all diameters. Our standard sizes are 6 inches to 40 inches but larger ones are available.

How do I connect the spark trap to my ductwork?

To make it easy to install your spark trap, you can choose from three end types. We manufacture them with a raw end, a flanged end, and a quick connect end for clamping. Larger models can be heavy and may need hangers or other support.

Where in the ductwork does a spark trap go?

A spark trap can be installed vertically or horizontally. For proper functioning of the spark trap, the length of duct between the spark source and the spark trap should be at least one duct diameter, and between the spark trap and the dust collector should be at least ten times the duct diameter. A shorter distance will prevent the spark trap from working correctly and is not recommended. If you have a question about the length of ductwork, we suggest that you contact us for assistance.

Do I need additional support to hold up my abort gate?

In most cases you will need a dedicated support due to the weight of an abort gate.

Do I need a ladder and a service platform?

It is not totally necessary, but NFPA suggest that you need to regularly inspect and service your gate.

Do I have to mount the abort gate horizontally?

Yes. The gate is gravity operated with spring assist.

Can an abort gate be mounted inside?

Yes. It is important to check with your local building codes regarding venting a potential fire through the duct. They may have requirement of material thickness, gaskets, etc. The most important thing to be aware of is making sure that you are venting into a safe direction.

Why are some gates so much less expensive than others?

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. We feel that our 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.
