Non-Adhesive Vents

Donaldson Non-Adhesive Protective Vents are designed to protect enclosures and devices from particles, water, oils, and other liquids without negatively affecting their operation. They are comprised of a filtration material that can be welded to a plastic housing or directly onto the device.

  • 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

Handling Instructions

  • 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

Assembly Instructions

  • 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
