Parker Chomerics family of honeycomb vents are utilized in electronics enclosures where EMI shielding and heat dissipation are required for long-term performance. Specific design considerations for honeycomb vents include overall size, EMI attenuation values, airflow rates, corrosion prevention, durability, and flame resistance. Parker Chomerics has a variety of vents that each serve specific applications or meet industry design needs.
Parker Chomerics Foam Filter Vents primarily provide filtration of moving air within and through electronic enclosure housings while also providing the opportunity for EMI shielding. EMI shielding is accomplished though the addition of honeycomb sheets, identical to those used in SHIELD-CELL™ and OMNI-CELL™ designs.
Features and Benefits:
• Additional shielding is possible with double layered OMNI-CELL™ honeycomb sheets incorporated in the panel
• Filter consists of a polyurethane foam with 20 or 40 pores per inch
