What Are the Benefits of Using HYDAC Filters in Industrial Systems?
If contamination gets into a hydraulic or compressed air system, performance drops fast – and the costs usually follow.
HYDAC filters are designed to protect your industrial equipment from this.
They keep the system clean by stripping out the particles that shouldn’t be in your compressed air or hydraulic fluid. Take that contamination away, and everything runs more reliably, costs stay under control, and the wider process tends to run far more smoothly.
What Is the Primary Risk to My Hydraulic or Compressed Air System?
The biggest risk is your system getting dirty.
Particles, moisture, even fine oil mist – they all try to creep into the system sooner or later.
If any of them slip through that first line of defence, trouble tends to follow. Oils lose their stability, sludge begins to settle in the wrong places, and after a while the filters are left working harder than they should. Components wear out faster, valves stick, and temperatures rise.
It’s a chain of events that sits behind many equipment failures, higher energy use, and the kind of unplanned downtime that gets expensive fast.
It’s exactly the issue HYDAC filters are built to prevent.
How Does HYDAC Filter Technology Solve Contamination?
HYDAC filters are not just simple screens. They use advanced, multi-layer technology to ensure your equipment is protected.
Here’s how their key technologies protect your system:
Optimicron®
This technology helps cut energy use in two ways. It runs with a low ΔP, so air and fluid move through it with barely any resistance – the compressor or pump doesn’t need to work as hard, and your kWh use drops straight away.
It also holds a surprisingly high amount of dirt, which means it keeps going for longer before you need to replace it.
Stat-Free®
This element stops oil breakdown at the source. It prevents static electricity from building up inside the system. This static discharge is a primary cause of sludge and varnish. Stat-Free® stops it from forming, keeping your oil and your components clean.
Aquamicron®
This element is designed to find and remove water from your hydraulic oil. Removing water is critical. It prevents rust, stops mould growth, and protects your oil’s ability to lubricate properly. This is essential for extending the life of your hydraulic hoses and pumps, as we detail in Industrial Filtration for Hydraulic Systems.
Betamicron® / Dimicron®
These are the high-reliability workhorses. They are built to provide guaranteed 99.9% filtration efficiency. More importantly, they feature “Beta Stability.” This means the filter will not collapse under high pressure, ensuring your system is always protected.
SUSTAINMICRON®
This is HYDAC’s environmentally optimised media. It uses fewer resources to produce and extends element life, all while delivering the same high-level protection.
Q1/Q2 Classification
This is your guarantee of quality. It confirms the filter is made to full OEM-grade standards and will deliver the performance it’s meant to – consistently and without fuss.
How Do HYDAC Filters Compare to OEM or Generic Filters?
Choosing a filter has a direct impact on your system’s health. While generic filters may seem cheaper, they often cost more in downtime and energy.
Here is a direct comparison:
| Feature | HYDAC Filters | Atlas Copco (OEM) | Generic Filters |
| Media | Multi-layer glass fibre | OEM coalescer | Paper or simple media |
| Differential Pressure | Very Low | Low | High |
| Efficiency (Beta Ratio) | 99.9% (Stable) | OEM-grade | Inconsistent / Varies |
| Collapse Resistance | High | High | Poor / Low |
| Oil/Water Removal | Excellent | Strong | Weak / None |
| Service Life | Long (High DHC) | OEM cycle | Short |
| Energy Impact | Lower $\Delta P$ | Low $\Delta P$ | High $\Delta P$ |
| Bypass Valve Accuracy | Precise / repeatable | OEM-calibrated | Inconsistent / risk of early bypass |
| Warranty Risk | Low | Low | High |
The takeaway is clear: A high-performance filter provides reliability. A generic filter introduces risk.
Are HYDAC Filters Compatible with Atlas Copco Compressors?
Yes. HYDAC elements work smoothly with Atlas Copco systems and are often chosen as a straight, high-performance upgrade.
They match or exceed the performance of OEM filters (like the DD+, PD+, and QD+ series) and can help you achieve the highest air quality standards, including ISO 8573-1 Class 1 and Class 0.
For VSD (Variable Speed Drive) compressors, HYDAC elements are a smart choice. Their low-pressure-drop design reduces the motor load, helping the VSD maintain its setpoint using less energy.
Many operators also use HYDAC elements to increase service intervals because their high dirt-holding capacity means they last longer.
What UK Industry Standards Do HYDAC Filters Meet?
Using genuine HYDAC filters helps you meet your UK and international compliance duties. This gives you peace of mind and ensures you are ready for any audit.
HYDAC filters are manufactured to meet key standards:
- ISO 8573-1 & ISO 12500: Together, these two standards map out what “clean” compressed air should look like – and the sort of performance a filter has to reach to meet that mark.
- PSSR 2000: The right filtration plays a central role in keeping your pressure system safe and meeting your legal duties.
- COSHH: These systems deal with the oil mist and stray contaminants that can hang in the air – making the workspace noticeably safer for the people around it.
Some filter ranges go a step further. You’ll find options cleared for ATEX use in explosive environments, and others that carry WRAS approval for drinking-water applications.
How Do I Select the Right HYDAC Filter?
Choosing the right element isn’t just a case of lining up part numbers. It starts with looking at how your system actually runs and what it needs from its filtration.
For a full breakdown, see our Expert Guide to Industrial Filtration.
Our team checks several key criteria:
- System Type: Compressed air, hydraulic, or process fluid.
- Required Cleanliness: The target particle size and efficiency.
- Media Type: Glass fibre, polymer, or stainless steel mesh.
- Flow Rate & Pressure: The filter must be rated for the system’s maximums.
- Fluid Compatibility: Ensuring seals match the oil or fluid.
- Installation: The physical size, port type, and mounting.
