Donaldson Ultrafilter DF Compressed Air Filter
The filter design combines high performance, increased efficiency, ease of use, flexibility, and safety.
High Performance – The filter design optimized for flow, paired with innovative filtration technology, reduces pressure loss by 50% compared to traditional filters.
Safety – A unique sponge lock prevents the filter from being opened under pressure, ensuring greater safety.
Energy Savings – Timely filter element replacement leads to increased energy savings. Element replacement is determined by the Economizer, which continuously measures differential pressure. An integrated microprocessor evaluates the measured data and compares the higher energy costs caused by pressure loss with the cost of a new filter element.
Ultra Filter Compressed Air Filter - Donaldson Filter
Significant performance improvement with new filtration technology. Alongside electricity, water, and gas, compressed air is one of the most commonly used energy sources. Therefore, the following factors must be considered to obtain high-quality clean compressed air:
• Economical filtration
• Performance validated according to ISO 12500-1 standards
• Filter reliability in compliance with ISO 8573-1:2010 Compressed Air Quality Standards
The most important part of any filtration system is the filter element. The new filter material, manufactured with high production technology and optimally pleated, enhances separation and purification performance while reducing pressure loss caused by resistance by approximately 50%. The filter surface area has been expanded to retain a higher amount of contaminants.
Unrivaled high performance
The new Ultra-Filter has been developed based on worldwide experience and more efficient – economical filtration technology.
• Filter design optimized according to capacity minimizes pressure loss.
• Advanced filtration technology ensures high separation efficiency.
• Complete solution for unrivaled efficiency.
With computer-aided simulation, optimum air flow rate has been calculated, and a turbulence-free design has been applied to both the filter element and housing, thereby guaranteeing low pressure losses.
Cost savings due to energy efficiency
More economical filtration is only achievable by reducing the differential pressure created by the filter. A mere 200 mbar reduction in differential pressure allows a compressor running 8,000 hours per year to save approximately €1,500 in electricity costs. (7 bar operating pressure, 120 kW screw compressor, electricity unit price €0.08/kWh). As the example shows, the filter investment pays back in under one year.
In subsequent stages, energy savings require that filter elements be replaced at the correct time. This economic interval is calculated by an electronic component called the Economizer. Differential pressure is measured continuously, and these values are evaluated by a microprocessor, which compares energy costs with the cost of new filter elements. When the most cost-effective time for filter replacement arrives, an LED signals “Filter Change.”
Using the correct materials is also important for economical filtration. Depending on the application and required air quality, one or more of six different types of filter elements may be needed. In doing so, it is essential to keep the differential pressure to a minimum. Coarse pre‑filters, micro filters, precision filters, and activated carbon filter elements are used as required for efficient purification.
• Multiple housing sizes, element types, and accessories – offering unique, customized solutions for every application.
• Optimized flow design – 50% reduced pressure drop – minimal pressure loss, resulting in lower energy consumption compared to conventional filters.
• Performance data validated in accordance with ISO 12500‑1 (oil aerosols), ISO 12500‑2 (oil vapours), and ISO 12500‑3 (particles) – ensuring reliable compressed air filtration per ISO 8573‑1:2010.
• Filter element removable together with the filter bowl – minimizes space required for filtration installation and service.
• Code clip inside the filter housing adjustable for multiple flow directions – dual-purpose housings can serve as combination filters (inside‑out flow) or particulate filters (outside‑in flow).
• Bayonet filter bowl lock – filter cannot be opened under pressure – high safety.
• Integrated differential pressure gauge – ensures the user replaces the filter element at appropriate intervals.
• Dip‑coated housing – provides long‑term corrosion protection.
