With the dust collection system doing, well, precisely what it's supposed to,

collecting dust, it becomes the perfect fuel for a plant fire or explosion. It's a system

of highly flammable, well-ventilated material that has an express lane across a plant.

Dust Collector valves within that system could play a significant role in containing a

fire before it travels further down the line.


All Dust Collectors are non-compliant because they have rubber-tipped vanes that

can't withstand heat from a fire or contain an explosion.  Let's not forget the housing.

All Dust Collector housings have thin sheet steel that is bent into shape. These

valves can't stand up against the pressure from an explosion, allowing a fire to

expand and grow.


All Dust Collectors have non-compliant inboard bearings. When a seal fails, it allows

product to get to the bearing ultimately making the bearing fail too. Bearing failure

can lead to metal-to-metal contact,  leading to sparks. This turns a dust collector into

a flint and tinderbox, sparking a fire with no obstacles to contain or extinguish it.

What is the solution?

Rotary Airlock has engineered and developed NFPA Compliant Dust Collectors that

exceed safety standards across all makes & models. With thick carbon steel housings

that are hand-welded and individually inspected, you can rest assured your valves are built to withstand the pressure of a fire.

You won't find any rubber or plastic-tipped vanes either. Rotary Airlock's Dust Collectors tout 8 completely steel vanes instead of the non-compliant 6 rubber-tipped vanes. These completely steel vanes carry clearances no more than .0079in from the housing too. This NFPA compliant clearance suffocates a fire, quenching its oxygen supply and helping contain the fire, ultimately aiding extinguish it.

That's just the base of each model. Can we introduce you to a maintenance and compliance dream outboard seal & bearing system?

Rotary Airlock's proprietary Rapid Access endcap configuration carries an outboard piloted flange bearing and also has Rotary Airlock's exclusive outboard MAP Seal System. With this configuration, we have removed the ignition source from the equation entirely. That's not all either, with the Rapid Access endcap configuration you can monitor and completely change seals & bearings in under 15 minutes AND you will be able to replace them in-line!

The ultimate safety valve. . .

Those upgrades are just the base for every dust collector. Rotary Airlock has gone even further to offer Direct Drives for ANY make & model as well. This Plug-N-Play set-up is the industry safety standard that minimizes access to moving parts and alleviates additional parts &  inventory requirements. It also requires less maintenance time & labor, thus saving your budget and ultimately increasing profits.

To see more, select your dust collector valve from the list and discover how your valve can become NFPA compliant.

8-Vane completely steel rotor.

With 8-Vanes these rotors are completely steel, so standing up to the heat is a walk in the park.


With clearances under .079in these rotors help suffocate fires too, keeping them from spreading and aiding extinguish them sooner.

Ignition point removed completely.

With an outboard piloted flange bearing the Rapid Access endcap configuration has removed the ignition point from the equation.

You can rest easy knowing your valves won't become a fire hazard. 



Change seals & bearings, IN-LINE.

In less than 15 minutes, you can change our proprietary MAP Seal and piloted flange bearing all In-Line.
