EZ-Bio 20 Pre Filter Double Core

Product details

EZ-Bio 20 Pre Filter Double Core is a simple, biomechanical pre-filter system designed to protect pumps and filtration equipment from debris-related flow reduction. It uses two filter core elements mounted over a rigid slotted pipe, helping capture suspended particles before they reach the pump. In practical setups, it’s commonly used with circulation pumps, filtration pumps, and water fountain pumps to reduce premature clogging and support smoother pump performance.

Features:

• Helps prevent flow reduction by trapping debris before it reaches the pump
• Supports pump longevity by reducing stress caused by premature clogging
• Two-stage core design with an internal Gray core plus a larger Green outer core element
• Large filter volume helps capture, store, and biologically process organic particles
• Progressive density and multiple pore sizes reduce clogging by spreading loading across the core
• Expandable design: multiple slotted pipes can be connected to increase filtration capacity
• Easy installation with universal barbed fittings that connect to common tubing sizes and adapters
• Easy cleaning by dunking the cores in pond water between maintenance intervals

Specifications:

• Core elements: 2 (internal Gray core + larger Green outer core element)
• Outer Green core size: 8 in diameter x 7.5 in long
• Replacement Gray core size: 4 in diameter x 7.5 in
• Replacement Green core size: 8 in diameter x 7.5 in
• Connection fit (tubing/adapters): Universal barbed fittings accept 1" to 1-1/2" tubing or 1-1/2" MPT
• Slotted pipe connection threads: 1.5 in male thread (one end) and 1.5 in female thread (other end)
