World Pressure Filters
The Standard in 7,000 psi Pressure Filters
138
WPF Series
Applications
Parker engineers have developed
what soon will be the industry
standard in high pressure
hydraulic ltration. e new
7,000 psi WPF series incorporates
many advanced features designed
for one reason: to improve your
bottom line.
ere is no better high pressure
lter available today for durability
and performance. e reduction
of your operating costs is our
primary concern, and we are
committed to contributing
towards your success.
Typical Applications
• Aircraft Ground Support
• Injection Molding
• Mining
• Mobile Ag
• Mobile Construction
• Oil & Gas Exploration
• Power Generation
• Primary Metals
• Refuse Trucks
