Industrial Strength Electrostatic Filters … Still Going Strong 47Years Later

From the paper mills on the west coast to the textile mills on the east coast, Permatron Corporation still manufactures the original industrial workhorses of permanent, washable electrostatic air filtration.  Utilizing the principle of a unitized filter bank, their Model IN and HFA have outperformed and outlasted metal mesh filters in many heavy-duty industrial applications.  The benefits of cleanability and long-term durability in high velocity systems or caustic environments gives customers the least cost over useful life, energy efficiency and an environmentally friendly solution to their air filtration needs.

Manufactured the same way since being introduced in 1957, Permatron’s unique filter construction features an exclusive Accumulator Chamber® design.  Engineered with a three-stage filtration process, the air filter maintains a high dirt holding capacity without face loading or restricting airflow.  Multiple filtration panels are encased within an outer steel frame, building the multi-stage filter bank.  The first panel acts as a prefilter.  When particulates build-up on the prefilter, airflow causes them to break off and be swept into the Accumulator Chamber, where turbulence and electrostatic forces cause agglomeration into even larger particulates.  These particulates are too large to pass through the second panel.  The afterfilter attracts and holds the smaller particulates that may have escaped the prefilter, or did not respond to an electrostatic charge.  The filter design is easy to clean thoroughly, and usually outlasts the system that it’s been installed in.  No system modifications or electrical connections are needed.
