Spare Parts Kit: Replacing the Friction Pair – Quick and Easy

Extend the service life of your compressor with a new cylinder head

Compressors from Dürr Technik are fitted with a high-quality cylinder head (Head Kit) featuring a particularly durable friction pairing.

To ensure your compressor performs at its best, the cylinder head should be replaced at regular intervals.

The use of compressors is so specific that we cannot specify fixed replacement intervals for the friction pair spare parts set. However, we have compiled some guidelines and recommendations for replacing the cylinder head for you below. You can also see in an example video just how quick and easy the replacement process is.

If you have any questions, our service department will be happy to offer advice and assistance.

Which user group do you belong to?

The interplay of various factors and the nature of use can help determine when you should consider replacing the spare parts set for the friction pair.

Low usage

e.g. in the medical sector, e.g. a clean laboratory:
Replace after 6 years.

Medium wear and tear

e.g. in single-shift industrial operation, depending on environmental factors:
Replacement after 2.5–5 years.

Maximum usage

10 hours a day with a 70% duty cycle, as in fast-food chains:
Replacement after 1.5–3 years.

These factors influence the service life of the friction pair:

Various factors determine the service life of the friction pair. A particularly decisive factor in wear is the number of operating hours, which depends heavily on the specific application.

Operating hours

Temperature

Particle

Humidity

Cost-effective replacement rather than an expensive new purchase

Good to know: Depending on the model, the price of a head kit is only 10–15% of the compressor’s original price. Naturally, each spare parts kit comes with the relevant instructions for the replacement.

Changing the filter – quick and easy

Once serviced with a suitable replacement filter, your compressor will perform just as well as a brand-new unit. The filter should therefore be changed annually.

Watch the video to see how quick and easy it is to change the filter.

Questions and Answers

Analytical instruments require oil-free, dry and particle-free compressed air. These requirements usually correspond to the compressed air classes set out in ISO 8573-1, typically Class 1:3:1, in order to prevent measurement errors and contamination.

Rheometers often use compressed air for air bearings. Oil or moisture can impair the bearing’s function and adversely affect measurement accuracy.

Yes, if designed appropriately, a central compressed air station can supply several analysers. Alternatively, decentralised solutions such as the SICOLAB mini are a sensible option for individual devices.

The SICOLAB is designed for higher flow rates and centralised applications, whilst the SICOLAB mini offers a compact solution for individual workstations and smaller analytical instruments.

Oil-free laboratory compressors significantly reduce maintenance requirements, as no oil changes are required and the risk of contamination is minimised.
