About this product

For a Superior Level of Particle Removal Efficiency, Choose the Model HFA Electrostatic Air Filter

The Model HFA Electrostatic HVAC Air Filter is an excellent choice for hospitals, laboratories, computer rooms, food packaging plants, and pharmaceutical plants.
Accumulator Chamber provides triple-action filtration

The Model HFA washable electrostatic air filter for commercial HVAC air handling systems contains multiple layers of custom woven electrostatic polypropylene media, plus non-woven polyester. The result is superior dust holding capabilities.

In addition, the 1-inch and 2-inch models feature the exclusive Accumulator Chamber. By using a unitized filter bank design, multiple layers of media assembled in a steel frame provide a distinct separation to create a triple-action filtration system. The pre-filter/after-filter assembly promotes free airflow while resisting face loading. Excess particles sweep through the pre-filter. Cross-currents within the chamber cause further agglomeration and settlement until the filter is rinsed clean. The outer frame contains strategically placed drain holes for thorough cleaning.

HFA Electrostatic Air Filter Features

  • The standard frame is available in galvanized steel. Stainless steel or aluminum frames are also available for an upcharge.
  • Combination electrostatic polypropylene and non-woven polyester media with wire reinforcement.
  • Exclusive ACCUMULATOR CHAMBER® design for maximum performance.
  • Drain holes positioned for easy cleaning
  • No system modifications or electrical hook-ups are needed.
