The Honeywell F52F1048 is a complete system that includes the chassis with the power box, grille door, one electronic cell, one pre-filter. Ready to install in the duct and connect the 120v to run.

The Honeywell F52F maintains peak air cleaner efficiency over a wide range of cell dirt loading conditions through the use of a self regulating dual voltage high frequency power supply. The dual voltage increases particle charging efficiency with a high 8150v ionizing wire voltage and increases collection surface area through a reduced 4280v plate voltage. The dual voltage is a feature exclusive to Honeywell.

Also exclusive to the F52F is a very sensitive

differential pressure sensor making the Honeywell compatible
with slow variable speed air handlers. Galvanized cabinet recesses into duct opening on wall or ceiling. On wall
installation, mount with hinge on bottom or either side.
Two year warranty.

We recommend soaking the collector cells. Soaking cleans better than the dishwasher and cleans better than a pressure washer. The cells typically do not need to be cleaned as often as the prefilters.

After cleaning, inspect the cell plates for dirt, hold the cell up to light. View the plates through the ionizing section to see the dirtiest side. Note that only every other plate captures dirt.

The plates are either charged or grounded. The charged particles are attracted to the grounded plates and repelled by the charged plates. Closely check the grounded plates, where as the charged plates will clean easily.
