Replacement Filter Elements

Yes, STAUFF replacement filter elements are identical in installation, function and performance to standard original products.
They fit into existing filter housings from many international manufacturers without any design changes and comply with all relevant standards such as ISO 16889, ISO 2941, ISO 2942 and ISO 3968.
This makes them ideal as a reliable, high-quality replacement for OEM filters - worldwide.

There are three precise, quick options:

• STAUFF.com filter search - ideal for identification by manufacturer or type number
• Online filter search at www.filtersuche.de - large, cross-manufacturer comparison database
• Direct support from STAUFF experts - particularly helpful for special types, older systems or exotic OEM numbers

STAUFF has over 65,000+ comparison data records, which means that almost every common filter element from international brands can be mapped.

The required filter rating depends on the most sensitive machine or hydraulic component in the system - e.g. servo valves, pumps or proportional technology.
The STAUFF filter guide, which contains guide values for different applications and cleanliness classes (e.g. based on ISO 4406), provides assistance.

Basic rule:

• Finer filtration (3-10 µm) for highly sensitive systems
• Medium filtration (10-25 µm) for standard hydraulics
• Coarse filtration (40-1000 µm) for suction and protection filters

STAUFF offers filter elements with a filtration grade of 3 to 1000 µm.

Yes, in addition to classic hydraulic oils, STAUFF offers media-specific versions for:

• Water and water-glycol media
• Cooling lubricants and emulsions
• Chemicals and process fluids
• Diesel, heating oil and other fuels

The wide variety of materials - glass fibre nonwoven, polyester nonwoven, stainless steel nonwoven, wire mesh or cellulose - enables use in many industries worldwide.

Yes, STAUFF offers extensive engineering and manufacturing options for special types:

• Deviating dimensions
• Special sealing materials (e.g. EPDM, FKM)
• Special filter media or finenesses
• High-pressure or high-temperature versions
• Elements for chemical or marine applications

Ideal for international industrial plants, spare part adaptations or modernisation projects (MRO).

Yes, STAUFF covers almost all well-known OEM brands, including for:
Hydac, Hengst, Argo-Hytos, MP Filtri, Donaldson, Filtrec, Mahle, Parker, Pall, Internormen and many more.
The fully compatible elements make it much easier to obtain spare parts worldwide.

STAUFF elements are available for almost every operating mode:

• Return line filter: 10-25 bar
• Pressure filter: up to 210 bar
• Suction filter: up to 10 bar
• Temperature and chemically resistant variants are also available.

This makes them suitable for hydraulic systems in all climate zones and branches of industry.

Thanks to state-of-the-art filter technologies such as 4PRO glass fibre fleece, they offer:

• high dirt-holding capacity (DHC)
• Low differential pressures
• Long service life
• Stable β values (βx ≥ 200 - ≥ 1000)
• energy-efficient system operation

This reduces maintenance intervals and operating costs - important for globally distributed industrial plants and fleets.

They are used worldwide in demanding applications, including

• Industrial hydraulics & mobile hydraulics
• Marine & offshore
• Energy and environmental technology
• Chemistry, petrochemistry & process engineering
• Machine tools and production systems
• Coolant, lubricant and fuel systems
• Gearbox & unit construction

This makes them ideal for global supply chains and international plant operators.
