1. How are Pall’s Ultipleat SRT Filters different from other filters?
Pall’s Ultipleat SRT filters have a unique wave-shaped pleat geometry that:
These filters deliver improved filtration efficiency and longer filter service life.
2. What is the performance rating of Ultipleat SRT Filters against other similar filters?
Tested via the Cyclic Stabilization Test against similar filters rated at 5 micron per ISO 16889, Ultipleat SRT filters provided far superior particulate removal under the cyclic and dirt loading conditions.
At 80% net terminal pressure drop, filter A is passing over 1200 times more 6 micron(c) and larger particles than the Ultipleat SRT filter, filter B 675 times more (see the image below).
3. How does the element removal mechanism in Ultipleat SRT Filters work?
A unique feature in Pall’s Ultipleat SRT Filters is the Auto-Pull filter element, allowing hassle-free element removal from the filter housing. When the cover or tube (depending on the assembly design) is unscrewed from the housing, tabs on the filter element endcaps fit into hooks in the housing.
Thus, as the cover or tube is unscrewed, the filter element is automatically pulled from the tube. This eliminates the need to reach into the tube to grab an endcap or handle and manually pull out the element.
4. How effective is a smaller filter compared to a larger fan-pleat filter in service?
The combination of maximized filter area, optimized pleat geometry, and uniform flow distribution in a stable, wave-shaped pleat geometry provides significantly more filtration area, compared to a traditional fan-pleat element of the same envelope size.
Of equal importance, these design features allow users to choose a smaller filter for an application and still obtain comparable filter element service life.
The above figure illustrates how a smaller Ultipleat SRT filter element can be used in place of a larger fan-pleat element. The smaller Ultipleat SRT filter element has a slightly higher clean pressure drop, but the overall service life of the two different size filters is equivalent.
5. Do Pall’s Ultipleat filters reduce electrostatic charging?
Electrostatic charge is generated by the flow of hydrocarbon fluids through porous media contained in a filter element. With low fluid electrical conductivity, this static charge can accumulate on the filter element and later discharge, causing noise and potential damage to the filter element, filter housing, or fluid.
Pall Ultipleat SRT filter elements incorporate anti-static materials to reduce charge generation and virtually eliminate static discharges.
