Application
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 is two years from the date of receipt for this product as long as this product is stored in its original packaging in an environment below 80° F (27° C) and 60% RH.
Handling and Installation Guidelines
(Note: The following content is only applicable to manual installation plan, if you need to know automatic installation plan, please contact ZZPIP sales staff.)
- Operators should wear latex and powder-free gloves or fingercots when handling adhesive vents.
- Avoid direct contact with the active venting area.
- Keep all sharp or jagged items away from the ePTFE membrane.
- To prevent damage to the product, do not pry the diaphragm directly from the release film.
- 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.
-
1. Preparation
- 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.
- Isopropyl alcohol can be used to clean the enclosure’s mounting surface.
- Ensure that the enclosure’s mounting surface is dry prior to vent installation.
-
2. Positioning
- The product should be mounted only on interior housing surfaces, ensuring the e-PTFE membrane side facing the external environment.
- 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
- 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.
- Ensure the entire adhesive ring is pressed against the surface.
- Allow 24 hours cure time before using or testing.
-
4. Note
- Once installed, vents should not be repositioned.
- Vents will be damaged when they are removed from the mounting surface.

Frequently Asked Questions
The typical air flow rate is 2300 ml/min @ 7Kpa, with a guaranteed minimum air flow rate of >1500 ml/min @ 7Kpa.
This vent membrane features an IP68 protection rating according to IEC 60529, with a water entry pressure of >10 KPa for 30 seconds (tested under ASTM.D751).
It is widely used in Automotive Lamps, Automotive Sensitive Electronics, Outdoor Lighting, Outdoor Electronic Devices, and Household Electrical and Electronics to balance pressure differentials and block environmental contaminants.
The product has a shelf life of two years from the date of receipt, provided it is stored in its original packaging in a controlled environment below 80° F (27° C) and 60% relative humidity (RH).
No, vents should not be repositioned once installed. Attempting to remove the vent from the mounting surface will cause physical damage to the membrane structure.
The mounting surface must be completely smooth, dry, and clean of oils, particles, or contaminants. You can clean the surface using Isopropyl alcohol and let it dry fully before applying the vent.
