HITEK supply a range of military specification vents. These include Cho-Cell™ and Omni Cell™ honeycomb vents and VIP™ vents.
The Cho-cell™ vents offer high levels of airflow combined with high levels of shielding due to the large open area of the honeycomb and the combination of the honeycomb size, aspect ratio and the plating of the honeycomb.
The Omni Cell™ vent offers a slightly different construction with two layers of honeycomb placed at right angles to one another to eliminate the polarisation effects of the honeycomb. The construction is chromate converted. It offers a cost effect alternative to the Cho-Cell™ construction as it eliminates the plating of the frame and honeycomb. It results in a vent that is thicker for a given shielding performance and also has a slightly higher resistance to airflow.
Finally there is the VIP™ range of vents. These are designed to provide a level of dust protection while also providing a level of shielding. They can be used with or without the viscous oil coating.
