HDF Mist Eliminators

HDF Mist Eliminators

Oil-lubricated air compressors can generate oil and water mist that can contaminate a compressed air system. With capacities of 125 to 8,000 SCFM, HDF Mist Eliminators remove oil and water mist from the air to optimize downstream processes and protect compressed air tools and equipment. Conventional filtration typically has much higher pressure drop and much shorter element service life than a Mist Eliminator, which can result in significantly greater air system operating cost. HDF Mist Eliminators also provide protection of downstream air treatment and process equipment in the event of catastrophic failure of the air compressor oil separator.

Effective Deep-Bed Filtration: At the heart of the HDF Mist Eliminator is a robust element of deep filtration media. As compressed air that’s contaminated with oil and water mist flows through the element, aerosol particles are collected in three ways:

1. Direct Interception - results when particles 3 microns or greater collide with media fibers. They then coalesce to form droplets that migrate downward.
2. Inertial Impaction - occurs when particles 1–3 microns collide with fibers as the airstream passes through the random media network. The droplets that form then migrate downward.
3. Brownian Movement - causes interception of extremely fine particles within the media. These particles have a random side-to-side motion—'Brownian Movement'—that’s triggered by collision with air molecules.

High coalescing efficiency results from long compressed air residence time through the filter media. Low internal velocity prevents oil re-entrainment while generous surface area keeps pressure drop ultra-low over the life of the element.
