Industrial compressed air filters ISO 8573.1
Effectively remove mechanical impurities, water, and oil from compressed air thanks to our extensive program of industrial filtration. Professional air treatment guarantees not only excellent medium quality for the most demanding applications, but above all multiplies the lifespan of your pneumatic tools and production technologies. In this category, you will find top-class industrial filters from proven brands such as Omega Air, Hankison, B-Air, NGF, or Mark. We naturally also supply replacement filter, catalytic, and adsorption cartridges for all types of filters. Details on filter classification and filtration principles can be found below.

Why is it essential to filter compressed air?
Air drawn in and compressed by a compressor (whether piston or screw) is not suitable for industrial and professional use without subsequent treatment. The compressor's intake, while capturing the coarsest particles, is far from being the main problem that threatens your technology.
What does untreated compressed air contain?
- Mechanical impurities: dust, fine pollen, rust, and loose scale from older pipe systems.
- Moisture: condensed water formed by physical compression and subsequent cooling of the air.
- Oil vapours and aerosols: these are present in all oil-lubricated compressors.
This harmful "triple combination" is a ticking bomb for any connected equipment. Pneumatic tools gradually lose power, their consumption increases extremely, they corrode internally, fine transfer ports become clogged, and seals are irreparably damaged. For a large automated line full of valves, sensitive cylinders, and robotic elements, the consequences are even more devastating. Unplanned production shutdowns due to a seized pneumatic system can cost a company hundreds of thousands of crowns. Proper filtration is not a luxury, but a necessity!
Air quality according to ISO 8573-1
The primary guide for every operator is the international ISO 8573-1 standard. It sets 7 classes of compressed air quality (classes 0 to 6), with each of them precisely defining how many solid particles, water, and oil the air may contain for a given application. A standard blow-off gun has different requirements than a paint shop, and a food processing operation has completely different ones. If you are unsure, we have prepared a detailed guide for you: How to properly filter compressed air.
Quick navigation – filters by quality class (solid impurities):
- Quality Class 1 (Extreme purity – microfiltration of particles down to 0.01 µm)
- Quality Class 2 (Very fine filtration down to 0.1 µm)
- Quality Class 3 (Fine dust filtration down to 1 µm)
- Quality Class 4 (Basic filtration down to 15 µm)
- Quality Class 5 (Coarse filtration down to 40 µm)
- Class 6 and Class 7 (Coarse separators and cyclones)
Industrial filters by condensate drain type:
- 💧 Automatic drain: The best and maintenance-free solution. The filter bowl empties itself as soon as the condensate level reaches a certain limit.
- 💧 Manual drain: Condensate must be regularly checked and drained by manually pressing or turning the valve at the bottom of the filter.
- 💧 No condensate drain: Standard solution for specific dust filters or activated carbon bodies where no liquid water occurs.
We provide a complete range for maintenance:
Purchasing the housing is not the end; we have consumables and service materials permanently in stock:
- Original filter cartridges (for dust, fine, and microfilters).
- Absorbent and catalytic cartridges for activated carbon filters (removal of odors and gaseous oil).
- Visual and differential pressure gauges (indicators that signal with red or needle that the cartridge is clogged and restricts airflow).
