Swimming Pool Filter Pneumatic Separation ("Explosion")

Dr. Rowley is an expert on swimming pool filter pneumatic separation. This type of accident typically involves the top half of a pool filter explosively separating from the bottom half with enormous upward force, typically resulting in the top half becoming airborne. Dr. Rowley has been consulted in such cases for more than 40 years. 

Dr. Rowley's expertise in pool filters goes back to 1970 when, as Director of Engineering for a major swimming pool manufacturer, he engineered and pressure-tested more than 300,000 filters (approximately 30,000 per year) for 10 years. He has tested (and literally blown apart) hundreds of filters in the course of his research. The National Sanitation Foundation (NSF) awarded Dr. Rowley the 1985 Spes Hominum (For The Good of Mankind) Award for his doctoral dissertation on Hi-Rate Sand Filtration.  In addition, he served on the National Sanitation Foundation’s (NSF) Standard 50 Joint Committee (Circulating System Components for Swimming Pools, Spas or Hot Tubs) from 1974 to 1992.

When Dr. Rowley served on the National Sanitation Foundation’s (NSF) Standard 50 Joint Committee (Circulating System Components for Swimming Pools, Spas or Hot Tubs) from 1974 to 1992, he helped write the pressure test requirements for the NSF's Standard 50.

Drawing upon his more than 40 years of expertise in mechanical design and construction of swimming pools and their associated equipment facilities, Dr. Rowley is able to accurately analyze the quality and failure of pool filters and their components, whether or not they are NSF Standard 50 compliant.
