A Guide For Enhancing Hydraulic System Performance in Demanding Industries
THE IMPORTANCE OF INLINE FILTERS
Hengst Filtration (Formerly Rexroth) are hydraulic filtration leaders and have a focus on innovation and
quality. Hengst proudly designs and manufacturers
filtraton solutions that deliver maximum
performance, productivity improvements and ease of
servicing.
Inline filters are critical components in hydraulic systems, they ensure the cleanliness of fluids by removing solid contaminants.
Hydraulic systems are require increasing demands
for reliability and efficiency, especially in critical
industries. Hengst range of Inline Filters solves this
problem by offering innovative solutions tailored for
modern and demanding applications.
This guide explains how vital it is to select high quality Inline Filters to improve machine performance, and for minimising downtime and operational maintenance costs.
COMMON RISK IN HYDRAULIC FILTRATION:
How to Overcome Challenges in Hydraulic Filtration?
Hydraulic systems face significant challenges that can lead to inefficiencies, downtime, and increased maintenance costs if not addressed correctly. Some of the comon challanges and warning signs are:
- Contamination Risk: Particles and water entering hydraulic fluids can cause wear, corrosion and reduced system performance.
- Pressure Loss: Inefficient filtration leads to clogged filters, resulting in pressure drops and disrupted operations.
- Frequent Maintenance: Low quality filters may require frequent replacements, this increases operational costs and downtime.
- Reduced Equipment Lifespan: Accelerated wear on pumps, valves, and other critical components and this may shorten your machine or equipment life.
To address these issues, a reliable filtration solution is essential, one that minimises contamination, ensures consistent system performance and ensures reliability between maintenance intervals.
THE SOLUTION:
How Hengst Inline Filters Are Engineered to Deliver Unparalleled Performance
- Proven Efficiency: The Cyclone Effect and PURE
POWER elements work together to maintain optimal
fluid cleanliness, improving system performance and reducing wear on components. - Built for Durability: Hengst filters feature durable
construction and advanced designs to withstand
high pressures, extreme conditions, and demanding
workloads. - Simplified Maintenance: Tool-free filter element
changes, optical maintenance indicators, and split
filter bowls minimise downtime and streamline
servicing - Customisation and flexibility: With features like
UNF threads, vent valves, and optional mounting
configurations, Hengst filters adapt to a wide variety
of hydraulic systems and industrial requirements. - Long-Term Cost Savings: By reducing contamination-related failures, this optimises your equipment performance, and helps to lower operational costs over time.

INLINE FILTER INDUSTRY APPLICATIONS
Mining and Heavy Equipment
In harsh mining environments, hydraulic systems endure extreme conditions such as high dust levels, extreme
temperature and heavy loads. The benefits of Hengst Inline Filters include:
– Prevent contamination-related failures in plant equipment and heavy machinery.
– Prolong component life by maintaining fluid cleanliness, reducing unplanned downtime.
– Support efficiency in equipment that operates continuously under challenging conditions.
Manufacturing
Precision manufacturing relies on the reliability of hydraulic systems to ensure smooth and accurate operations.
– Protect critical components in CNC machines, assembly lines, and hydraulic presses.
– Maintain consistent fluid cleanliness, minimising wear and extending service intervals.
– Prevent interruptions caused by contamination, ensuring higher productivity and operational efficiency.
Industrial and Steel
Industrial facilities depend on durable hydraulic systems for seamless operations, with Hengst you can:
– Optimise performance in demanding environments such as steel, chemical and power plants and facilities.
– Reduce the risk of failures caused by contaminated fluids, lowering maintenance costs.
– Enhance system durability to support long-term, uninterrupted operations.
TECHNOLOGY INNOVATIONS
Cyclone Effect & PWR Power Filter Elements
Hengst’s Cyclone Effect technology revolutionises filtration efficiency as fluid enters tangentially, creating a helical flow around the filter element. This unique flow pattern directs heavier particles to the filter bowl bottom, reducing clogging and extending maintenance intervals by up to 7–10%.
The PURE POWER filter element integrates a six- layer material composition, including asymmetrical micro-glass fibers and electrically conductive layers, ensuring:
- High Dirt Holding Capacity: Captures 50% more
contaminants while maintaining low pressure
drops. - Extended Service Life: Reduces replacement frequency, improving system uptime.
