Smog-Hog SG-4S is a single-pass electrostatic air cleaner. 4,000 – 5,000 Nominal CFM Capacity, includes inlet plenum with plenum filter. They are good for a free air system or ducted light smoke or oil mist application. For a heavy smoke application, a double-pass system is recommended. Two of these can be joined together by removing the blower section to make a double pass SG-4S-M.

These air cleaners are in good working condition.
They will be checked out before shipping, which includes:

  • New belt
