Unrivaled high performance. Donaldson was developed on the basis of worldwide experiences and innovative design resulting in a highly efficient and economic filtration concept.
• A flow-optimized filter design provides minimum pressure loss.
• The innovative filtration technology ensures high separation efficiency.
• A total filter design concept delivers unrivaled efficiency.
Computer-aided simulation was the basis for the turbulence-free design with optimized airflow through the filter housing and into the element. This ensures low pressure losses. The core of each filtration system is the filter element. Careful selection of filtration media, optimized pleating, and advanced production technology, produce a reduction of pressure loss by 50% while concurrently increasing separation efficiency. The element coalescing drainage layer is fixed in place by the outer support sleeve ensuring a constant cross-section between the element and housing at all times.
The economic efficiency is clearly indicated by the reduction in differential pressure. A 3.0 PSI lower differential pressure over 8000 operating hours at 600 scfm saves $1,452 per year (based on 100 psig operating pressure, 120 kW installed power and $0.08/kWh.) This practical example shows that the investment in optimizing the compressed air system rapidly pays for itself.
Unrivaled Energy Savings
Further energy savings are achieved by the timely replacement of used filter elements. The most economic time for filter changeout is determined by the Economizer that continuously measures the differential pressure. An integrated microprocessor evaluates the measurement data and compares the higher energy costs caused by pressure loss with the costs of a new filter element. The most cost-effective element replacement time is calculated and LEDs then signal that filter changeout is necessary.
Unrivaled Ease of Use
The new Donaldson Ultra-Filter is unrivaled in its ease of use both during installation and filter element
replacement. The filter bowl is rotated slightly via a bayonet lock and can be removed together with the filter element requiring only an inch of ground clearance. The integrated condensate drain allows new element changeout without disconnecting power and condensate drains. The cover with integrated differential pressure displays can be rotated so that the display stays visible from the selected side.
All filters can be used either as coalescing filters (flow through the element from the inside to the outside) or as particulate filters (outside to inside flow). If the requirements change, the filter head does not need to be rotated. Changing the coding clip inside the filter bowl allows the filter element to be rotated and changes the flow direction. The coalescing filter becomes a particulate filter in seconds - and vice versa. Optional wall supports are available on request for flexible wall mounting. The telescopic design of the support provides broad adjustability. A series of filters with different element types maybe installed with connection adapters. The Ultra-Filter is simple to mount and fits into the smallest space.
