Fire safety at the core

  • 8-Vane completely steel rotor*
     

  • Ignition point removed entirely with outboard bearings
     

  • Close Clearance configuration to quench any possible ignitions.

Rotary Airlock has engineered and developed NFPA Compliant Valves 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 NFPA Valves contain at least 8 completely steel vanes instead of the non-compliant 6 or rubber-tipped vanes of some valves (primarily dust collectors). 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 flames, 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 too?

​

Rotary Airlock's proprietary Rapid Access endcap configuration on NFPA compliant valves carries an outboard CLF Bearing System and Rotary Airlock's proprietary MAP Seal System.

 

With this NFPA & Maintenance focused configuration, you can monitor and completely change seals & bearings In-Line and in under 15 minutes so get the best of safety and convenience today.

Completely Steel Rotor

Ignition Point Removed

Change Seals & Bearings In-Line

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

 

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

.

With Rotary Airlock's CLF Bearing System, the Rapid Access endcap configuration has removed the ignition point from the equation entirely.

​

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

In less than 15 minutes, you can change our proprietary MAP Seal and CLF Bearing Systems In-Line.

​

No need to pull an airlock means less downtime, less labor, and more product & profit for your bottom line.

YOUR DEFENSE

AGAINST PLANT

FIRES & DEFLAGS

Starting with Rotary Airlocks premium construction standards, (American Sourced, carbon steel, hand-welded, full steel rotors & housing, with close clearance configurations, and maintenance geared outboard systems), makes Rotary Airlocks NFPA compliant valves what the rest of the industry strive to be.

SAFETY FIRST

With so many valves (especially dust collectors) fabricated from foreign gauged rolled steel and containing rubber-tipped vanes (wiper blades), the safety of your plant and people needs to start right at the construction standards of your equipment. Here is a look at Rotary Airlocks NFPA compliant dust collector construction materials and thickness.

WHY IT MATTERS

                                 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.
