Are you looking for a particular spare part or air end? Simply contact us by phone or email.

Prolong the lifetime of your current rotary screw compressor by consistently performing oil changes and regular maintenance. While these practices can extend the overall durability, it’s crucial to acknowledge that, over time, the air-end and motor bearings of your compressor will inevitably need replacement. Don’t risk the failure of your air-end, as the expenses associated with renewing it far surpass the cost of re-bearing.

Our service offers a re-bearing solution for your air end. This option ensures longevity comparable to that of a brand-new air end, providing you with a cost-effective and efficient alternative.

In many cases only the main component of the compressor – the screw element – needs replacing. In our spare parts depot we stock a huge selection of quality used air ends. These air ends have been checked and are sold in a good working condition. Tell us the make and type of your compressor for which you require an air end. You can contact us by phone or email or complete our enquiry form.

Used elements

These air ends from the compressed air brands like Atlas Copco, Kaeser, CompAir and Boge have been checked and inspected by our well-trained technicians and are sold in working condition.

Refurbished elements

These compressor elements from the compressed air brands like Atlas Copco, Kaeser, CompAir and Boge are refurbished here in our in-house workshop by our well-trained technicians. All refurbished air ends are sold with a comprehensive guarantee.

Which procedure we have by refurbished stages

The rebuilding procedure initiates with a thorough disassembly and examination of the air end. Every element, including bearings, journals, gear fits, and bearing bores, undergoes visual scrutiny and precise measurements. Housings and rotor sets are meticulously inspected for any signs of damage. Our standard work scope encompasses the fitting of new premium-quality components such as bearings, seals, gaskets and O-rings. Any necessary metal repairs are carried out, and rotor sets undergo dynamic balancing for optimal performance. The air end will be painted and carefully palletized with a wooden box for shipment.
