Fann mixers conform to American Petroleum Institute Specification 13A

 

Fann Laboratory Mixers are two speed mixers, available in both 115 and 230 volt models with no load test speeds of 11,000 RPM and 15,000 rpm. These have the standard impeller blade for mixing either water-based or oil-based drilling fluids. Powerstat® variable trans-former (sold separately) is used to provide an extended mixing speed range.
