have higher physical strength and better shielding effect than most of aluminum honeycomb ventilation panels, and are generally used in applications where SUPER high EMI/RF SHIELDED EFFECT is required.
We have a comprehensive range of steel Shielding Ventilation Panels and filters available to allow unrestricted air-flow whilst preventing the transmission of electromagnetic interference , RF. Hengshi can provide you best shielded honeycomb vent solution on professional aspect. Double layer honeycomb screens and slant honeycomb screens are optional.
Application:
computer chassis/rack, communication shelters, EAP enhancement, TEMPEST (Transient Electromagnetic Pulse Emanation Surveillance Technology) equipment , etc.
Heating ventilation and air conditioning systems,Cooling high power systems/circuits e.g. radar, RF comms, power supplies, etc
Generators
Welding unit
Engines
Test Rigs
