Product Details
Coalescing (Pre-Filter) Filters Often called the pre-filter since itis placed on the air line just prior to the air dryer, a coalescingfilter removes oil, particles and moisture before it can come incontact with the desiccant in the dryer and ruin it.
DD(+)/PD(+) SERIES
High performance oil coalescing filters
DD(+) and PD(+) filters efficiently reduce oil aerosol,wet dust and water drops in your compressed airstream. These could come from the lubrication of the compressor element, the intake air, and the compressor installation itself. These innovative filtration solutions are engineered to cost-effectively provide the best air purity and meet today's increasing quality demands.
TEST STANDARD:
Our filter elements are tested according to ISO 2943
