GENERAL: FDP polyester disposable filters are heat resistant when used in air conditioners, they are also recommended for industrial, residential and commercial use.

MANUFACTURING: Vermont FDP polyester filters are designed with sturdy cardboard frame, with progressive density filter fabric, standard measurements are 1″ nominal thickness (7/8″ accurate measurement), 2″ nominal thickness (1-3/4″ accurate measurement) and 4″ rated thickness. Each 1″ thick square foot weighs approximately 26 gr. And the 2″ thick weight is approximately 35 gr. This weight can include a colorless, adhesive oil-inodore layer, which helps to stop dirt particles in the filter surface, providing high performance filtration. Perforated sheet support grilles are corrosion resistant and are placed on both sides of the filter both the mats and the support grilles are continuously glued around the perimeter of the frame, thus obtaining excellent results in terms of filter stiffness and firmness. This design eliminates the possibility of the filter fabric sinking into the frame.


FABRIC: Thickness in inches .0.150(3.8), weight per square foot in grams, Initial efficiency in % of particles 50-60, flammability s class 2, Air permeability in inches of water 0.18″.
SUPPORT: Corrosion-resistant perforated sheet metal on both sides of the filter.
ADHESIVE: Mixture of hot resin or glue.
FRAME: Made of sturdy cardboard.
