Features and Benefits:The depth style Profile A/S 1401 Series PPS filter element offers the following benefits versus commonly utilized pleated paper 1401 style filters.
|No potting agents utilized||No potting agents used to attach filter end caps as is done with 1401 style pleated paper elements||Wider temperature and chemical compatibility|
|Depth style media||Greater ability to remove soft deformable contaminants||Enhanced fluid quality|
|Fine fibers utilized||Medium void volume >80% vs <50% for paper medium||Long filter life|

4 Pressure drop in PSI per GPM water for a single element. Multiply this value by the required flow to determine the total aqueous pressure drop. Next, for fluids other than water, multiply by viscosity in centipoise. If this calculated pressure drop is excessive, then divide this value by the number of filters required to reduce this pressure drop to an acceptable level.
MCC1401 Housings - Aqueous Pressure Drop
To calculate the actual housing pressure drop, multiply this aqueous pressure drop by the fluid’s specific gravity. This value must be added to the filter pressure drop to calculate the overall pressure drop of the filter system.
A full line of standard and custom Pall MCC1401 housings, designed and built to the ASME code, are available. Refer to Table 2 for more information.
A Pall supplied retrofit tie rod assembly is required to utilize Profile A/S 1401 style elements in existing 1401 style housings. This assembly allows for use of a knife edge seal style element in a housing that normally accepts end capped filters with internal O-rings.
The retrofit assembly consists of a top and bottom seat cup and tie rod. The bottom O-ring to knife-edge seal cup is placed over the housing riser pipe. The Profile A/S 1401 Series element is placed over each tie rod. The elements are sealed in place by screwing the top metal seal nut onto the top of the tie rod. When fully engaged, the tie rod/seal nut assembly forms a knife-edge sealing surface at both the top and bottom of the element.
