Description
Donaldson compressed air filter elements
Donaldson compressed air filter elements are designed to prolong the life of your equipment and ensure a clean, stable airflow. Each element features high contaminant retention, low pressure drop and system flexibility – whether you need a coalescing filter, a particle filter or both in one.
We are the official representatives of Donaldson in Lithuania.
The filter elements use an advanced UltraPleat™ pleated media made of coated high-tech fibres – providing exceptional fine particle filtration, oil mist removal and liquid/gas coalescence. We supply elements compatible with Donaldson DF, SG, HD, EG, P-EG and PG-EG housings. Many series are available in HTNX (high temperature) and HTCR (corrosion resistant) versions for harsh operating conditions.
Donaldson filtration solutions comply with ISO 8573-1:2010 compressed air purity classes from Class 1 to Class 5 in terms of particulate matter, water dew point and oil concentration.
