Bonded vents are laminated with membrane and double-sided tape. Adhesive vents are sold in rolls or sheets. Packaging can also be customized according to customer requirements. Bonded vents are thin, lightweight, and easy to design and install. Bonded vents are the ideal solution for small spaces, thin-walled enclosures and applications requiring automated installation. We can select membrane type, shape and size based on the customer's IP rating, ventilation or cooling requirements. We can also help choose the right adhesive based on the different contact surfaces.  DCCK can provide more than 50 standard sizes, and the size and shape can also be customized.
