Ultipor Filter Elements - A History of Filtration Technology Innovation

Pall introduces Ultipor® Filters

	ß = 75 removal efficiency
	Glass fiber media 1^st in industry
	Fixed pore media and wire mesh up and downstream support

Pall Ultipor II Filters introduced

	ß = 200 removal efficiency 1^st in industry
	Tapered pore media 1^st in industry
	Polyester upstream support and wire mesh downstream support 1^st in industry

Pall Ultipor III filters introduced

	ß > 200 removal efficiency 1^st in industry
	Nylon support mesh up & down 1^st in industry
	Patented outer helical wrap 1^st in industry

Pall Coreless Ultipor III filters introduced
1^st in industry

	Same performance as Ultipor III filters
	No metal parts (plastic end caps and core is part of housing)

Pall Introduces Ultipor SRT stress-resistant filters
1^st in industry

Resistant to stresses caused by:

-	Cyclic Flow

-	High pressure drop (due to cold start and filter loading)

Vibration

Higher flow capacity (low clean pressure drop)

Smaller and lower cost assemblies for new installations

Performance rated as ISO Code achieved at worst operating condition (80% pressure drop) per the Stress-Resistance Test
