TABLE 2.0.2 – TBV RELIABILITY
SPECIFICATION COMMENTS
* MTBF > 2 million cycles or > 11,500 hours
Processes with large amounts of effluent contamination or highly aggressive chemistries may reduce the MTBF due to
condensation on moving parts and/or O-ring degradation.
* Warranty 1 year
*Not applicable to UVD-series products
