Fisher T205

Tank BlanketingThe T205 Series tank blanketing regulator is a direct-operated and spring-loaded regulator. 

The regulator prevents a stored liquid from vaporizing into the atmosphere, reduces liquid combustibility and prevents oxidation or contamination of the product by reducing its exposure to air.

The T205 Series maintains a slightly positive pressure and thereby reduces the possibility of tank wall collapse during pump out operation. The T205 Series is available in two configurations: Type T205 for internal pressure registration and Type T205M for external pressure registration.
