Pentair DE Grid Manifold | 192193
Pentair DE Grid Manifold | 192193
Pentair DE filter grid manifold 192193 has been discontinued and is no longer available from the manufacturer.
This listing is maintained for product identification, compatibility, specifications and repair-reference purposes only. This exact manifold cannot be ordered or backordered through Aqua Terra Backyard.
No direct replacement should be selected without confirming the exact Nautilus filter model and internal grid configuration. The manifold used in newer Pentair FNS Plus filters is not automatically interchangeable with this legacy Nautilus component.
Pentair Nautilus D.E. Filter Grid Manifold with Air Relief | 192193
Pentair 192193 is the complete upper grid manifold used in compatible legacy Pentair and PacFab Nautilus vertical-grid diatomaceous earth filters. It sits above the filter grids, keeps the grid necks properly positioned and collects filtered water from the individual elements.
The integrated air-relief screen allows trapped air inside the filter to move through the internal relief system. A cracked, distorted or damaged manifold can allow D.E. powder and unfiltered water to bypass the grid assembly and return to the swimming pool.
What the Manifold Does
- Seats the upper neck of each vertical D.E. filter grid
- Maintains proper grid alignment inside the filter tank
- Collects filtered water from the individual grid elements
- Directs filtered water toward the filter outlet
- Supports the internal air-relief system
Common Signs of Manifold Damage
- D.E. powder returning through the pool inlets
- Visible cracks around grid openings or the outlet neck
- Filter grids that will not remain properly aligned
- Missing or damaged internal air-relief screen
- Debris bypass despite intact filter-grid fabric
Product Features
- Legacy Nautilus filter component: Designed for compatible Pentair and PacFab Nautilus NS and Nautilus Plus NSP vertical-grid D.E. filter systems.
- Complete upper manifold: Provides the molded upper structure that connects and supports the individual filter grids.
- Integrated air-relief screen: Helps move trapped air through the filter's internal air-relief pathway.
- Supports proper D.E. filtration: Correct grid seating helps prevent openings where D.E. powder or debris could bypass the filter elements.
- One manifold across several filter sizes: The same manifold design was used with several legacy Nautilus filter sizes while the grid length and complete grid assembly varied by square footage.
- Exact model identification required: This manifold should not be selected only by appearance because newer FNS Plus filters use a different manifold specification.

Do Not Confuse 192193 with the FNS Plus Manifold
Pentair 192193 was used in legacy Nautilus NS and Nautilus Plus NSP filters. Pentair 59023700 is identified in current documentation as the top manifold for the newer FNS Plus filter family.
Although the two components may appear similar in photographs, the outlet neck, grid spacing, center hardware and air-relief configuration may differ. Part 59023700 should not be advertised as a guaranteed replacement for 192193 without confirming the complete filter model and physical fit.
Inspection and Service Guidance
Turn off the circulation pump, disconnect power and completely relieve pressure through the manual air-relief valve before loosening the filter clamp or opening the tank.
- Confirm the complete filter model from the tank label
- Inspect the manifold for hairline cracks and warped grid openings
- Inspect every filter grid for torn or separated fabric
- Check the outlet neck and standpipe connection for damage
- Clean and inspect the internal air-relief screen
- Verify that each grid neck is fully seated in the manifold
- Inspect the lower grid locator and center hardware
- Replace damaged seals rather than relying on sealant
- Recharge the filter with the correct amount of D.E. after service
Frequently Asked Questions
Is Pentair 192193 still available?
No. Pentair 192193 has been discontinued and is no longer available through Aqua Terra Backyard. This page remains online for product identification, fitment and repair-reference purposes.
What is Pentair part 192193?
It is the complete upper grid manifold with air-relief screen used in compatible legacy Pentair and PacFab Nautilus vertical-grid D.E. filters.
Which filter models commonly use 192193?
It is primarily associated with legacy Nautilus NS and Nautilus Plus NSP filters, including several 24, 36, 48, 60 and 72-square-foot configurations. The tank model should always be confirmed before identifying an internal part.
Does this listing include the filter grids?
No. Part 192193 identifies the upper grid manifold. Individual filter grids, complete grid packs, lower grid locators, tie rods and other internal components are separate parts.
Does the original manifold include an air-relief screen?
Yes. The complete 192193 manifold is identified with an internal air-relief screen that helps vent trapped air from the grid assembly.
Can a cracked manifold cause D.E. to enter the pool?
Yes. A crack or poorly seated grid opening can allow D.E. and debris to bypass the filter grids. Torn grid fabric, a damaged outlet connection or a missing air-relief screen can produce similar symptoms.
Does Pentair 59023700 replace 192193?
It should not be treated as a universal direct replacement. Pentair identifies 59023700 as the manifold for FNS Plus filters, while 192193 is associated with legacy Nautilus NS and NSP filters. Exact model and dimensional compatibility must be confirmed.
Is 192193 compatible with every Pentair D.E. filter?
No. Pentair manufactured several generations of vertical-grid D.E. filters. Nautilus NS, Nautilus Plus NSP, FNS and FNS Plus model names should not be considered interchangeable.
Should the grids be inspected when servicing the manifold?
Yes. Inspect every grid for tears, split seams, broken necks and fabric separation. A new manifold cannot correct D.E. bypass caused by damaged filter grids.
Can the filter be operated with a cracked manifold?
Continued operation is not recommended. A damaged manifold can permit filtration bypass, allow D.E. to return to the pool and prevent the internal grid pack from remaining correctly aligned.
Need Help Identifying a Legacy Pentair D.E. Filter?
Match the tank model, square-foot rating, manifold shape, outlet neck and grid length before selecting any internal filter component.
