Permanently clean hydraulic fluids are the basis for the performance and longevity of machines. Off-line filters from ARGO-HYTOS take on the task of permanently removing unwanted particles from the fluids used.

Off-line filters are independent systems that are used outside the main circuit of the hydraulic system. This allows particles, water and other impurities to be removed from the oil without interrupting the operation of the machine for cleaning work. Find out in this article what off-line filters are suitable for and how they contribute to reliable fluid cleaning in hydraulic circuits.

What are off-line filters and how do they work?

An off-line filter is an independent filtration system that works in parallel with the main circuit of a hydraulic system. It only ever treats part of the oil. This is in contrast to the main flow filter, which is integrated directly into the main circuit and cleans the entire fluid flowing through it.

The main advantage of off-line filtration is its efficiency in removing fine particles and water from the oil, combined with a huge dirt holding capacity. Due to their special design, off-line filters can filter out contaminants that may not be captured by mainstream filters. This prevents significant damage to the hydraulic components used, which can be caused by even the smallest particles.

In addition, the removal of water from the system prevents oxidation and corrosion. This improves performance and significantly extends the service life of the hydraulic components.

Off-line filters are installed either during the initial assembly of the machine by the manufacturer or as a retrofit option by the user. A major advantage of retrofitting is that the installation does not require any changes to the existing hydraulic circuit.

The efficiency, high dirt holding capacity and excellent water absorption of off-line filtration are often enhanced by extra features such as oil condition monitoring. ARGO-HYTOS off-line filters can be used over long periods of time without the need for costly maintenance or regular replacement. Off-line filters are therefore a cost-effective solution that helps to extend the service life of the hydraulic oil and thus reduce operating costs.

How do stationary off-line filters work and what are their areas of application?

Stationary bypass filters, also known as off-line filters, are independent filtration systems used for the continuous cleaning of hydraulic fluids. Their main advantage lies in their ability to improve the quality of the hydraulic oil without affecting the existing hydraulic circuit or machine operation.

The filters can be installed either by the machine manufacturer during initial installation or by the end user as a retrofit.

In combination with other filter units, such as pressure filters, off-line filters ensure permanently flawless oil quality.

For example, the FNS1 040 off-line filter from ARGO-HYTOS is a high-performance stationary off-line filter with a water-absorbing element. It offers excellent water absorption capacity - regardless of the system temperature. Additionally, it enables the removal of solid particles and has an enormous dirt holding capacity, which has been confirmed by tests in accordance with ISO standards.

Specialized off-line filter units such as the FNA1HV 008 are used for filtration in hydraulic and lubrication systems with high viscosities. It offers a compact, robust and leak-free design and a large dirt-holding capacity. The filter elements can be changed without tools and during operation.

Off-line filters from ARGO-HYTOS are available for original equipment, as part of a retrofit or for retrofitting machines. The filter solutions guarantee continuous filtration of the fluids - even when the main cylinders of the machines are not in motion.

What functions and advantages do mobile oil service units from ARGO-HYTOS offer?

Mobile oil service units from ARGO-HYTOS are multifunctional devices specially designed for the location-independent maintenance and servicing of hydraulic systems. The units can be used for the following tasks:

• Transferring oil
• Pumping out used oil
• Filling machines with filtered oil
• Off-line filtration

The UMPC2 mobile oil service unit is one of the latest additions to the ARGO-HYTOS portfolio. Apart from the great performance guaranteed by the well-known UMPC 045, the UMPC2 is additionally characterized by an ergonomic touch display, optimal handling and high filter performance.

Alternatively, the economical UMPCL2 045 oil service unit also offers high filter performance and ease of use.

The most important features of all units of the UMPC family are as follows:

• Easy replacement of the filter element
• Integrated sensors for monitoring the oil condition
• Storage of data and settings in individual profiles
• Optional flexible flow regulation in the range from 20 to 70 l/min
• Ergonomic design for easy handling and clean transportation

The core element of the complete family of the UMPC units is the ultra-fine filter element, which has a high separation efficiency up to 4 kg. It therefore guarantees an outstanding level of oil cleanliness. This offers maximum protection for the components in the overall hydraulic system.

Mobile oil service units are an economical and flexible alternative to stationary off-line filters. We would be happy to advise you on the advantages of both solutions in a personal consultation. Get in touch with our team of experts now!

How do mobile dewatering systems from ARGO-HYTOS affect oil quality?

Mobile dewatering systems from ARGO-HYTOS ensure the lasting quality of hydraulic and lubricating oils. Water contamination in oils can have serious consequences, which are reliably prevented by the mobile dewatering systems. The vacuum dewatering units from ARGO-HYTOS are specially developed to remove both free and dissolved water from hydraulic and lubricating oils. This ensures the long-term performance of the oils.

Water contamination can negatively affect the efficiency of the entire hydraulic or lubrication system by

• Accelerated oil oxidation, which has a negative impact on air separation ability, anti-foaming agents and lubrication performance
• Degeneration of additives, which accelerates corrosion and wear
• Shortening the service life of the oil, which causes more frequent oil changes and therefore higher costs

The vacuum dewatering units from ARGO-HYTOS reliably remove water from hydraulic and lubricating oils. This prevents the formation of oxidation products, extends the service life of the oil and increases the overall efficiency of the hydraulic system. These units also help to reduce maintenance costs and downtime. This is because they reduce the need for frequent oil changes and extend the service life of the components.

The mobile drainage systems from ARGO-HYTOS support high-performance fluid management. This reduces operating costs and ensures the reliability of hydraulic systems.

Permanently clean oil with filtration technologies from ARGO-HYTOS

With filtration technology from ARGO-HYTOS, you can ensure the long-term cleanliness of hydraulic fluids or lubricants in your company. Our off-line filters or mobile oil cleaning devices make a significant contribution to the performance and longevity of machines. Both solutions have their own advantages.

Stationary off-line filters offer efficient and reliable cleaning and are suitable for both new machines and retrofitting.
