Installation method when the shell wall thickness is less than 3mm
Installation method when the shell wall thickness is greater than 3mm
Clean the mounting surface and the area where the snap-on vent will be installed to remove any contamination and allow the surface to dry after cleaning;
Chamfer recommended for optimum O-ring seal when wall thickness is appropriate;
Install the vent between 150 N and 300 N until an audible “click” is heard ensuring seal integrity.
Clean the surface on which the adhesive-backed vent is installed to remove any contamination and allow the surface to dry after cleaning;
Housings for vents, accurate placement of vents can be improved through the use of markings, recessed areas, or targeted areas;
Apply slight finger pressure (recommended 15PSI) on the rubber ring of the adhesive-backed venting membrane to ensure that the venting product can be firmly bonded to the shell;
Do not attempt to reposition the vents after installation, as this will cause the membrane to deform and fail;
A dwell time of at least 24 hours is required before use or testing of finished components.
The welded assembly consists of a SST Porous membrane with or without support material, which can be attached to the plastic shell by heat fusion, ultrasonic welding, bonding or overmolding to form a waterproof and breathable assembly.
Typical welded vents include:
Plastic housing – can be integrated with the filter media, can be easily installed into the housing, and can be selected from various thermoplastics (PBT, PA, ABS, PPS, etc.), elastomers (TPE) and other materials.
