Unicel 48 Sq Ft Partial DE Filter Grid Replacement
When a DE filter starts losing efficiency, the problem is often not the entire grid assembly—it’s a single damaged partial grid allowing debris and DE powder to bypass the filtration system. The Unicel 48 Sq Ft Partial DE Filter Grid Replacement is designed to restore proper filtration performance without the unnecessary cost of replacing a full grid set.
Manufactured with genuine Reemay® filtration fabric, this partial grid delivers consistent DE coating, high dirt-holding capacity, and long-term durability. It is built to OEM specifications, ensuring proper fit, correct spacing, and reliable sealing inside compatible 48 square foot DE filter systems.
This is the correct solution when your filter needs targeted repair rather than a complete rebuild.
Why Replacing a Partial Grid Matters
A single failed partial grid can compromise the entire filtration system. Common issues caused by a damaged grid include:
-
DE powder returning to the pool
-
Cloudy water even with balanced chemistry
-
Higher operating pressure and reduced circulation
-
Accelerated wear on the remaining grids
Replacing the damaged partial grid restores balanced filtration, protects the rest of the grid assembly, and helps extend the overall life of your DE filter.
OEM Fit with Reemay® Filtration Fabric
Unicel partial grids are engineered to match original manufacturer dimensions and tolerances. This ensures the grid installs correctly within the manifold, maintains proper spacing, and allows even DE distribution across the entire grid assembly.
The Reemay® fabric used in this grid is known for its strength, chemical resistance, and ability to hold DE evenly across the surface. This results in improved filtration efficiency and consistent water clarity throughout the cleaning cycle.
This is not a generic substitute—it is a professional-grade OEM replacement trusted by pool technicians.
Designed for 48 Sq Ft DE Filter Systems
This partial grid is intended for DE filters rated at 48 square feet that use a combination of full and partial grids. Using the correct partial grid is critical, as incorrect sizing or poor fit can cause internal bypass, uneven pressure, and damage to the filter manifold.
Replacing only the damaged grid allows you to maintain factory performance without the expense of a full grid replacement when the remaining grids are still in good condition.
When to Replace a Partial DE Filter Grid
You should replace a partial grid if you notice persistent cloudiness, visible fabric damage, DE returning to the pool, or uneven pressure readings after cleaning and recharging. Addressing the issue early prevents additional wear on the remaining grids and helps avoid more costly repairs later.
Installation Overview
Installing a partial DE grid is straightforward for anyone familiar with basic DE filter maintenance. The filter tank is opened, the grid assembly is removed, the damaged partial grid is replaced, and the system is reassembled and recharged with fresh DE. During installation, it’s recommended to inspect the remaining grids and manifold to ensure no secondary damage is present.
