Based on years of operational experience, we are launching an innovated range of WK piston aggregates. These new aggregates have successfully passed rigorous testing since the beginning of 2024 and are now ready for practical deployment. In terms of technical parameters, they remain fully compatible with the previous generation, while simultaneously introducing a whole range of improvements. Below, we present the main technical innovations of the new WK series and explain the benefits they bring to various industrial applications.
Technical Innovations of the New WK Series
The new WK generation includes several design changes and improvements that increase both the performance and the service life of the aggregates:
-
Precision Craftsmanship and Durable Parts: The new WK aggregates are manufactured with higher machining precision and fitted with more durable pistons and piston rings. The higher quality interaction of parts extends the life of the entire aggregate while reducing the amount of oil penetrating the compressed air. Furthermore, valve plates, reeds, and seals have been reinforced and made from premium materials from world-class suppliers (e.g., from Sweden and the USA), further increasing the reliability of these components.
-
Improved Filtration and Cleaner Air: Filter elements in the new aggregates are now manufactured using steel components and protected by a durable mesh. As a result, the filters have higher impurity-trapping efficiency and help maintain optimal compressor operating conditions. Additionally, steel air filter covers are now used across all models, offering better resistance to high temperatures and mechanical damage during transport and operation.
-
Bleeder Valve for Heavy-Duty Operation (WK 430): The WK 430 model is equipped with newly designed bleeder valves that prevent oil mist leakage even in extreme operating conditions. This minimizes oil loss and ensures the compressed air remains significantly cleaner.
-
Easy Startup After Downtime (WK 1500): For the largest model, the WK 1500, innovated piston pin bearings have been deployed for more reliable ignition after extended downtime. The compressor can start without difficulty even after a long period of inactivity, reducing the risk of the aggregate seizing upon restarting.

Customer Benefits
The mentioned technical innovations translate into a wide range of specific advantages for compressor users and operators:
-
Higher Operational Reliability: More robust construction and high-quality materials reduce the risk of malfunctions and unplanned downtime. Compressors with WK aggregates thus run more reliably, improving production continuity.
-
Lower Operating and Maintenance Costs: Longer service intervals, lower oil consumption, and slower wear of parts mean fewer expenses for maintenance and operation. Investing in the new WK series thus pays back in the form of savings throughout the equipment's life cycle.
-
Longer Equipment Service Life: Durable components and precision processing extend the overall lifespan of the aggregate and the entire compressor. The customer receives a device that will serve them reliably for a significantly longer time.
-
Cleaner Compressed Air: More effective filtration and limited oil leakage ensure higher quality of the supplied air. This is particularly appreciated by applications sensitive to air purity, where the risk of contamination by oil particles is minimized.
-
Easier Operation: Innovations such as better piston bearings facilitate compressor startup after downtime and reduce operational demands. Steel filter covers increase the equipment's durability during handling, making it easier to work with and less prone to damage.
-
Compatibility with the Previous Range: The new WK aggregates can be fully deployed in place of older types due to the preservation of identical basic parameters and dimensions. Modernization or replacement of the aggregate therefore does not require major interventions into existing systems.

Use in Industrial Applications
Thanks to the mentioned improvements, the new WK aggregates find application across a wide spectrum of sectors. Some examples where these features bring the greatest value:
-
Continuous Operations and Manufacturing: Facilities with 24/7 operation (multi-shift production lines in mechanical engineering, automotive, or other industries) will appreciate the high reliability of WK aggregates and the minimization of unplanned downtime risk.
-
Demanding and Dusty Environments: Construction, heavy industry, or mining operations require exceptionally durable machines. The robust construction and improved filters predetermine the WK series for deployment even in environments with high dust levels, vibrations, or significant temperature fluctuations.
-
Applications Requiring Clean Air: Food and pharmaceutical facilities, paint shops, or other applications sensitive to air quality demand minimum oil and impurity content. The new WK aggregates, thanks to effective filtration and oil mist reduction, ensure the necessary compressed air purity for these purposes.
-
Service Centers and Workshops: Auto repair shops, tire shops, and other workshops utilizing pneumatic tools will appreciate compressors with WK aggregates for their reliable operation and low maintenance requirements. Longer service life and lower part wear minimize downtime during service interventions.
-
Backup and Seasonal Equipment: Compressors serving as a backup source or used seasonally (e.g., in agriculture or for grounds maintenance) benefit from the easier startup after downtime featured in the WK 1500 model. Even after prolonged inactivity, the compressor can be easily put into operation without the risk of seizing, which is ideal for occasional use.
The new WK range of piston aggregates pushes the reliability and efficiency of piston compressors to a higher level. Users thus obtain a more reliable and economical source of compressed air for their business that can withstand even harsh operating conditions.
