Hayward Pro-Grid 48 sq. ft. DE Pool Filter - W3DE4820

The Hayward Pro-Grid 48 sq. ft. Vertical Grid DE Filter (W3DE4820) provides high-capacity filtration and superior water clarity for residential pools and spas of all sizes. By utilizing vertical grid technology and Diatomaceous Earth (DE), this filter removes the smallest impurities to leave your water sparkling and "polished."

• Service-Ease Design: Features a heavy-duty, one-piece flange clamp that securely fastens the tank while allowing quick, tool-free access to internal components.
• Rapid Air Relief: A high-capacity manual air relief valve allows for quick air bleeding with a simple quarter-turn of the lever.
