This document is for informational purposes only and should not be considered as a binding description of the products or their performance in all applications. The
performance data on this page depicts typical performance under controlled laboratory conditions, data is corrected to 0.075 lb./ft3 air density (29.92” Hg @ 70° F.).
Actual performance will vary depending on the operating environment and application. AMETEK Rotron products are not designed for use with volatile, hazardous or
corrosive gases. Blower housings are not sealed, slight air/gas leakage will occur. AMETEK Rotron products are not designed for and should not be used in medical
life support applications. AMETEK reserves the right to revise its products without notification. The above characteristics represent standard products. For product
