Prater Completes Testing To Become Only NPFA-69 Certified Rotary Airlock Valve Commercially Available In North America

In February of 2015 Prater Rotary Airlock Valves were tested at the Fike® Remote Testing Facility according to guidance found in NFPA 69.

Fike® concluded that Prater Rotary Airlock Valves "were structurally sound, exhibiting no visually observable plastic deformation in any test.  Additionally, valves successfully isolated the protection region from flame propagation." 

Fergus Keane, Vice President of Sales and Brent McIntosh, National Account Manager for Prater Industries both traveled to the Fike® facility to witness the testing.  Mr. Keane said, "The results of the testing mean that our customers can be confident that Prater Rotary Airlock Valves are the safest and most explosion resistant airlocks in their plant.  Ultimately, keeping workers safe and reducing downtime is what it’s all about." 

Rotary Airlock Valves are commonly used in industrial and agricultural applications as a component in bulk material handling systems. Rotary feeders are primarily used for discharge of bulk solid material from hoppers into a pressure or pneumatic conveying system.

Prater is located in Bolingbrook, Illinois and is an industry leader in material handling equipment.   Their product offering includes Rotary Airlock Valves, Fine Grinders, Air Classifying Mills, Lump Breakers, Sifters, Air Classifiers, and Compactors as well as Toll Processing Services.


Complete testing results are available upon request.  Testing video will soon be available on our website and YouTube.
