Reticulated Fan Filter Foam Media

GardTec’s complete family of reticulated, fully open-pore, flexible polyurethane foam filters are designed for environmental applications where dust and various other airborne particulate and contaminants are present. The foam is characterized by a patented three-dimensional skeletal structure of strands which provide a constant 97 percent of void space and a high degree of permeability.

Pore sizes of 30 PPI and 45 PPI are controlled with a ±5 PPI. Flow and filtering characteristics have an extremely low resistance to airflow. The higher the PPI number, the greater the density, allowing for higher particle collecting capacity. Standard temperature ranges are -40°F to +225°F. Filters are not affected adversely by water, soap, detergents, oils, cleaning solvents, or greases.

Electronics systems are protected from airborne contamination by foam filter pads installed in the plastic fan filter assemblies. The absence of metallic particles in foam material precludes interference with equipment operation, helping prevent contaminant loading on circuit elements, which can cause electric leakage, faulty signals, and static.

All GardTec foam filter is UL rated as UL94HF-1 for smoke generation.
