  • Hydrophobic, oleophobic, and acoustic materials are available
  • Thickness: < 0.3 mm / < 0.012 in
  • Continuous Operating Temperature Range: -40° to 149° C / -40° to 300° F
  • Minimum efficiency of 99.97% on 0.1 µm particles
  • Material data sheets available upon request
  • Accurate placement of the vents can be improved by using markings, a recessed area, or a target area in which the vent is centered over the vent hole in the device or housing
  • Apply light finger pressure to the adhesive ring to seal the vent to the device or housing
  • Do not attempt to reposition the vent after installation. This can cause damage to the vents
  • Allow at least 24 hours dwell time before using or testing the vent
  • Manufactured, inspected and packaged in clean room environment
  • Supplied on continuous release liner: 2000 - 5000 parts per polyethylene cores
  • Roll sealed in cleanroom bag unless otherwise specified
  • Wear gloves or use rounded tweezers when handling the vents
  • Mounting surfaces should be clean and free of oils, particles, and other contaminants
  • Vents should be mounted on flat, vertical surfaces where liquids or other contaminants will not pool
  • Follow dispenser instructions when using an automated vent dispenser
  • For manual vent dispensing, roll the liner under the vent until the vent extends beyond the liner and 
  • becomes easily accessible
  • Do not pry the vent from the liner or fold the vent, as this could damage the vent
