Donaldson products enhance operational safety and increase product and process integrity as well as energy savings for all types of compressed air, liquids and breathing air systems.
With an all-embraced service concept, a close support network, qualified service engineers and individual service offerings we are the perfect partner throughout the entire product life cycle of your system.
Donaldson provides services for all components of compressed air and breathing air systems as well as for air, gas, steam and liquid filtration solutions. Service agreements comprising different maintenance offerings are tailored to fit your needs and requirements.
Donaldson Filtration Services provide you with the assurance that we are with you throughout your filtration system’s life cycle, combining global expertise with a strong local presence.
Preventative maintenance avoids production downtime and reduces high operating costs. Our Donaldson service network is always nearby.
To ensure the perfect match between on-site operating conditions and system settings, professional commissioning is a must. Only when on-site operating conditions and system settings are perfectly matched will your system deliver the performance and reliability at the lowest operating costs.
To enhance and complement our field services, we provide highly sophisticated in-house laboratory services to validate oil aerosols, oil mist, particle size or concentrations.
The Bubble Point Test is a commonly used, non-destructive integrity test for membrane filters. Based on the filter type, materials used, wetting agent and the membrane design, the filter supplier defines a bubble point. Applying an increasing gas pressure from outside the water film covering the majority of pores breaks at a certain pressure (Bubble Point Pressure). If the pore structure of the membrane is defective, this breakthrough pressure lies below the value given by the supplier. Donaldson offers this measurement as a service for customers to detect leakages in membrane filter elements and to avoid potential contaminations in the filled beverages.
This test is commonly used to decide on the integrity of a depth filter element according to EN ISO 1822. The filter element gets challenged with a cloud of submicronic oil particles at the most penetrating pore size (0.2 micron – 0.3 micron). The number of penetrating particles defined by a laser scanner decides on the integrity of the filter element. Donaldson offers this measurement as a service for customers to detect leakages in filter elements and to avoid potential unsterilities in the filled or packaged goods.
The differential pressure is defined as the pressure difference between the filter inlet and the filter outlet. This test checks the efficiency of a cleaning process of the elements.
The particle content of liquids to be purified is crucial for the needed filtration stages. Donaldson’s measurement of the particulate is based on a light scattering analysis of the particle size distribution in water-based liquids in the range of 0.8 micron and 138 micron. This service will become the basis for our recommendation what filter types to use and how many filtration stages are actually needed . The particle analysis prior to any decision on the filters helps to set up filter lines with a maximum service life time and to minimize total cost of ownership.
Legal requirements call for the disposal of oil/water mixtures. With the condensate filtration test you can measure the condensate content and the degree of the compressor oil in the water. Donaldson provides a portfolio for the removal and treatment of condensate.
