Ordering Absolent replacement filters
When it’s time to replace filter cassettes, choosing original Absolent filters is the only way to maintain the unit’s original performance. Each cassette is built and quality-tested to match the exact specifications of your filtration unit.
Ordering is straightforward. Provide the serial number of your Absolent unit or the Art. No. of the filter cassette, and we ensure you receive the correct cassettes for your application. The serial number can be found on the machine plate of your Absolent unit and the Art No. on the filter cassette label located on your old filters.
Looks can be copied. Filtration performance cannot.
At the core of every Absolent unit are the filter cassettes, and their design is what enables the long-term performance we guarantee. Generic filters can match the shape, but not the engineered fiber structure that makes an Absolent filter.
Absolent filter cassettes are developed with unique fiber materials, controlled porosity, and glass chemistry designed for optimal oil drainage. A minor deviation in fiber quality can drastically affect efficiency and lifespan.
Choosing the correct filter cassette keeps operating costs low. Stable pressure drop reduces energy use, and long service intervals minimise downtime. Over the full life of the unit, this consistency has a measurable impact on running costs and air quality.
Filter types for every application
Absolent filtration solutions are used in a wide range of industries, from machining, grinding and die casting to forming, heat treatment, rubber and plastics, textiles, food production and other dry applications. Each process releases its own type of airborne contamination, and every application requires the correct filter cassette to manage its particle load and operating conditions.
- Mist filter cassettes – Captures the wet oil mist particles generated during high-speed machining and cooling operations.
- Oil smoke filter cassette – Designed for even smaller particles than mist filters, oil smoke filters stop even sub-micron particles.
- Dust filter cartridge – Used in dry machining, welding, and finishing operations to capture fine dust and fume.
Each filter type is part of a coordinated multi-stage system. Larger particles are captured and drained in the early stages, while finer aerosols are trapped in later layers and the HEPA stage. Absolent filter units can operate around the clock while keeping outlet air free from oil and harmful particles.
When operating conditions change
Changes in machining parameters, materials, or coolant can affect filter cassette lifespan. If operating conditions change, our engineers support you in optimising the filtration setup. This can include recommending alternative filter cassettes or adjusting the filter unit control settings. The goal is always to maintain stable performance, low operating costs, and long service intervals over time.
The core of clean air performance
Behind every Absolent filter cassette is a precise balance of materials and airflow engineering:
- Optimised fiber structure: The unique combination of fiber diameter, thickness, and density ensures high capture efficiency and effective drainage.
- Controlled airflow: Lower airspeed through the cassette gives particles time to separate without causing pressure loss.
- Engineered drainage:Oil collected in the fiber bed drains continuously, preventing re-entrainment and extending service life.
- High capacity: Each cassette is dimensioned for heavy particle loads, allowing stable operation even under continuous production.
Every component in the filter cassette contributes to the overall unit’s performance. The results are the values that define Absolent filtration — minimal maintenance, low operating costs and clean air always.
Filtration for sustainable operation
Longer service intervals and lower energy demand directly translate to reduced environmental impact. An Absolent unit running 24 hours a day can capture thousands of kilograms of oil annually while releasing less than 0.05 kg back into the air. The drained oil can often be reused, reducing waste, and supporting circular production goals. For manufacturers facing stricter regulations and higher standards, the proven filtration technology by Absolent is a reliable tool for more sustainable production.
Your partner in clean air
Every Absolent solution is built for long-term use, and the same applies to its filter cassettes. Using original components maintains warranty conditions, ensures consistent air quality, and keeps total cost of ownership under control.
If you are unsure which cassettes your unit requires, our team can assist with identification and ordering. Genuine Absolent filter cassettes guarantee the same performance and reliability you rely on every day.
