Fluoroflow-SELECT

The Fluoroflow-SELECT™ is Comparison of Ni Plating Filters
an all-fluoropolymer cartridge
that is compatible with the
most aggressive Nitric acid Fluoroflow
flushes. Unique SELECT pleating PES PS SELECT
technology increases filtration
area and flow rate by over 70% Membrane PES PS PTFE
versus standard filters. This Hardware PP PP PFA
has enabled dramatic success
in Nickel plating applications Diameter 2.75” 2.75” 2.75”

price of the individual cartridge Flow (gpm/psid) 1.8 3.0 4.6
was higher, overall filter costs Lifetime 1 1 12
were reduced by 16%. Fewer

biggest bonus, however, was
the yield improvements that Cost/filter/mo $80 $80 $67
were seen. Higher flow rate
of the Fluoroflow-SELECT
increased bath turnover, which
reduced particle levels. This
was confirmed by inline particle
testers. The inherent cleanliness Summary:
of the PTFE/PFA materials may
also have contributed to lower Industry Microelectronics - Nickel plating for hard disk drives
