HYDAC alternative filter elements – 1:1 fit, six-part structure.

Product Update: Aite Alternative HYDAC Filter Elements

1. Introduction

Aite Alternative HYDAC Filter Elements are core components widely applied in hydraulic, lubrication, and fluid purification 

systems across industrial machinery, metallurgy, wind power, mining, and injection molding industries. With the continuous 

development of domestic fluid filtration technology, Aite Alternative HYDAC Filter Elements have achieved full dimensional 

interchangeability, equivalent performance, and standardized production. These replacement products not only break the 

monopoly of imported original parts but also optimize procurement costs and supply chain efficiency for end users.

This article comprehensively elaborates the overall structure, internal working mechanism, complete technical parameters,

 mainstream material configuration, model coding rules, and performance standards of Aite Alternative HYDAC Filter Elements. 

All technical indicators are strictly designed and tested in accordance with international industrial standards – keeping consistent 

with genuine HYDAC filter elements in practical application, installation, and service life.

As a professional manufacturer specializing in import substitution filter consumables (not an authorized HYDAC distributor), 

we deliver Aite Alternative HYDAC Filter Elements with stable filtration performance, significantly shorter delivery cycles, 

and substantially lower procurement costs for industrial facilities worldwide.

2. Overall Structure

Aite Alternative HYDAC Filter Elements adopt a cylindrical folded structure – the classic design of original HYDAC products.

 The complete structure can be divided into six core parts: upper end cap, lower end cap, sealing ring, filter medium assembly,

 inner support frame, and outer protective net. Some special models are also equipped with built-in bypass valves to ensure system 

safety under extreme working conditions.

2.1 Upper and Lower End Caps

The upper and lower end caps of Aite Alternative HYDAC Filter Elements are located at both ends, serving as the positioning and

 connecting base. High-strength cold-rolled steel plate or reinforced engineering plastic is selected as raw material. For medium 

and high-pressure filter elements used in hydraulic systems, metal end caps are the mainstream choice due to excellent

 compression resistance and structural stability. The surface is treated with electrophoresis or spray coating to achieve rust

 prevention and corrosion resistance.

2.2 Sealing Ring

The sealing ring of Aite Alternative HYDAC Filter Elements is a key component to prevent fluid leakage between the filter

 element and the housing. Different rubber materials are configured according to operating temperature, fluid medium, 

and working pressure – including NBR, FKM, and EPDM. The sealing rings adopt integral molding technology with uniform 

hardness and good compression resilience.

2.3 Filter Medium Assembly

As the core functional part of Aite Alternative HYDAC Filter Elements, the filter medium assembly determines filtration efficiency,

 dirt holding capacity, and service life. The filter medium is folded into continuous corrugated shapes to expand the effective

 filtration area. Most high-performance alternative elements adopt multi-layer gradient composite filter media – with fiber

 density gradually increasing from outer to inner layer, forming a stepped filtration structure that balances filtration precision 

and dirt holding capacity.

2.4 Inner Support Frame

The inner support frame of Aite Alternative HYDAC Filter Elements is a spiral welded metal mesh cylinder installed on the inner

 side of the folded filter medium. Its main function is to resist the pressure difference formed by fluid flow. The rigid support

 frame prevents the soft filter medium from being squeezed, deformed, torn, or collapsed under medium and high pressure. 

The thickness of the support mesh and aperture are designed according to the pressure grade.
