HC9404FKN13H replacement filter – high flow, β≥1000, 1:1 fit.

1. Product Overview

Aite HC9404FKN13H High-Flow Replacement Filter Element is a

 high-performance filtration component designed for high-flow hydraulic and 

lubrication systems – featuring a unique shell design with multiple filter

 elements, backwash mechanism, and differential pressure controller. 

The diaphragm inside the housing divides the inner cavity into upper and lower

 chambers. The upper chamber accommodates multiple filter elements,

 making full use of filtration space and significantly reducing the overall filter 

volume, while the lower chamber is equipped with a backwash suction device.

Aite HC9404FKN13H High-Flow Replacement Filter Element operates on a 

proven filtration principle – during normal operation, turbid liquid enters the 

lower cavity of the filter through the inlet, passes through the partition hole into

 the inner cavity of the filter element, where impurities are intercepted by the 

filter media. The clean liquid then reaches the upper chamber through the filter 

element gaps and is discharged from the outlet. This outside-in flow design 

ensures efficient contaminant capture and easy maintenance.

As a professional manufacturer specializing in import substitution filter 

consumables (not an authorized Pall distributor), we deliver Aite HC9404FKN13H

 High-Flow Replacement Filter Element with stable performance, significantly 

shorter delivery cycles, and substantially lower procurement costs for industrial 

facilities worldwide.

2. Product Design & Filtration Principle

Aite HC9404FKN13H High-Flow Replacement Filter Element features an 

advanced design that maximizes filtration efficiency and minimizes footprint:

Compact Multi-Element Design – The upper chamber accommodates multiple

 filter elements, making full use of filtration space and significantly reducing

 overall filter volume compared to conventional single-element designs.

Outside-In Flow Direction – Aite HC9404FKN13H High-Flow Replacement Filter

 Element adopts an outside-in flow pattern, allowing contaminants to be

 intercepted on the outer surface of the filter element for cleaner handling and 

easier replacement.

Built-in Backwash Suction Device – The lower chamber is equipped with a

 backwash suction device, enabling cleaning of filter elements without complete 

disassembly, extending service intervals and reducing maintenance downtime.

Differential Pressure Monitoring – A differential pressure controller continuously 

monitors filter condition, providing real-time indication of contamination levels 

and signaling when cleaning or replacement is required.

Aite HC9404FKN13H High-Flow Replacement Filter Element captures various

 forms of pollutants from fluid media, including solid particles, metal wear debris,

 and colloidal contaminants. The filter element composition and its functions

 extend beyond standard filtration, encompassing magnetic filtration, 

electrostatic filtration, and separation filtration for specialized applications.
