Hydraulic oil filters protect machines and units for smooth performance

MANN+HUMMEL has been working on a wide variety of filtration solutions for over 80 years and sets standards in separating the useful from the harmful. We work in a solution-oriented way and meet current global challenges such as delivery performance and customer proximity. MANN+HUMMEL's proven reliability and quality as well as our regional and global production capacities make us a strong and reliable partner even in times of crisis. We make targeted use of our technical know-how to ensure effective protection of hydraulic components with high-performance filters.

Our highly effective hydraulic oil filter elements remove harmful particles from hydraulic oil thanks to their strong separation performance – with the aim of reducing machine and equipment wear and downtime, and also extending their service life. In this way, hydraulic oil components such as pumps, valves and cylinders are effectively protected over the long term – for high-performance and clean hydraulic oil systems. Various integrated functions enable versatile use in a wide range of positions in the hydraulic oil circuit and can be combined as required.

• Reliable protective filter of a wide variety of hydraulic systems
• Best filtration efficiency thanks to multilayer glass fiber media at the heart of the filter
• High dirt-holding capacity with minimal pressure drop
• Fast, easy and clean service
• Minimizes downtime and ensures long service life of hydraulic components and machines
• Additional components such as diffusers maximize hydraulic oil return to the tank
• Standardized interfaces on filters for different sensors as a basis for intelligent filter monitoring

The motto "time is money" has never been more relevant in industry and trade as it is today. Working under time pressure is standard, and the reliability of machines, systems and their hydraulic components is essential for economic success. The problem: Heavy dust loads can stress and damage hydraulic components. The consequence: Accelerated component wear, resulting in long maintenance times or even total failure of machines and systems.

Some causes of debris ingress into hydraulic systems:

• Poor component cleanliness in newly installed components, new connections or replacement components can lead to particle ingress
• Contamination from the working environment and also the ingress of dirt particles into the cylinders via the tank supply and exhaust
• Dirt can also enter during maintenance, for example, when opening the system to refill with new oil or when changing the hydraulic filters

Contamination can quickly lead to abrasive wear and the formation of secondary particles. In addition, contamination accelerates the aging process of hydraulic fluids.

Only optimum hydraulic filtration can counteract downtime. With its hydraulic oil filter portfolio, MANN+HUMMEL offers efficient, effective and long-term solutions for clean, functioning systems, machines and their hydraulic components.

MANN+HUMMEL fights against dirt particles in hydraulic oil systems. Our mission is to protect systems, machines and their performance in the long term with highly efficient hydraulic oil filters. The filters can be used in various positions in the hydraulic oil circuit and can be used in combination with each other at the same time to prevent hydraulic machine wear and downtime. Here are some examples of their application:

• Commercial vehicles
• Construction and agricultural machinery, e.g. hydraulic oil systems of tractors and excavators
• Forklift trucks
• Other mobile machinery, such as lifting platforms

You can rely on MANN+HUMMEL – everywhere and at all times. We focus on your requirements and specific needs. Even in challenging times, we stand for leadership in filtration. This is ensured by our comprehensive portfolio with various types of hydraulic filters: 

We understand our customers. To best serve them we rise to every challenge and find sustainable, economical solutions that are designed for the long term. Different areas of application require different hydraulic oil filters and, precisely fitting filter media:

• For fully synthetic media (MULTIGRADE O-S), a drainage grid keeps the pleats in an ideal position and ensures maximum stability and low differential pressure
• Glass fiber media (MULTIGRADE O-G) offer the highest collection efficiencies in the range of 3 to 20 micrometers (Beta = 200 according to DIN ISO 16 889) and so increase the dust holding capacity through an intelligent combination of pre-filter and fine filter layers
• A polyester or metal support grid helps stabilize the pleats on the pressure side of the hydraulic oil filtration system, even at high viscosity and high operating or differential pressures
