Adhesive Type Vent Membrane

This series of membranes could be used in Automotive Lamps, Automotive Sensitive Electronics, Outdoor Lighting, Outdoor Electronic Devices, Household Electrical and Electronics etc.

The membrane can balance inside/outside pressure differentials of sealed enclosures while blocking contaminants, which could increase components’ reliability and extend their service life.

Shelf Life：

Handling Guidelines 

1) Operators should wear latex and powder-free gloves or fingercots when handling adhesive vents. 

2) Avoid direct contact with the active venting area. 

3) Keep all sharp or jagged items away from the ePTFE membrane. 

Dispensing Guidelines 

1) To prevent damage to the product, do not pry the diaphragm directly from the release film

2) For manual dispensing, roll the liner under the vent, slowly over an edge, until the vent extends beyond the liner and becomes accessible. Blunt-edged tweezers may be used to remove the vent gently from the liner. 

Installation Guidelines

1. Preparation 

a) Ensure that the enclosure’s mounting surfaces are smooth, clean and free from oils, particles or other contaminants; free from jagged or rough edges that could damage the vent.

b) Isopropyl alcohol can be used to clean the enclosure’s mounting surface. 

c) Ensure that the enclosure’s mounting surface is dry prior to vent installation. 

2. Positioning 

a) The product should be mounted only on interior housing surfaces，ensuring the e-PTFE membrane side facing the external environment. 

b) In order to achieve the best performance, the film should be installed on a flat, vertical surface to avoid liquid or other contaminants on the surface of the film. 

3. Installation

a) Apply firm finger force at least twice in a circular motion directly to the adhesive ring area to seal the vent to the housing, being careful not to touch center of the vent area.

b) Ensure the entire adhesive ring is pressed against the surface. 

c) Allow 24 hours cure time before using or testing. 

4. Note 

a) Once installed, vents should not be repositioned. 

b) Vents will be damaged when they are removed from the mounting surface.
