Product Information

Full details

The Dryzone Telescopic Passive Vent is designed for homeowners seeking a simple, maintenance-free method to improve indoor air quality. Its primary benefit is reducing condensation and mould by continuously circulating fresh air. A potential caveat is its passive nature, meaning it relies on natural air pressure differences for ventilation. This unit provides silent, power-free air exchange, features adjustable ventilation control via an iris shutter, and installs easily through walls up to 500 mm thick.

FAQs

How does a passive vent work?

A passive vent works by utilizing natural air pressure differences and convection to circulate air. It allows stale, moist air to escape and fresh air to enter without the need for fans or electricity.

What is the maximum wall thickness this vent can accommodate?

The telescopic ducting allows for installation in walls up to 500 mm thick.

Does it require electricity?

No, the Dryzone Telescopic Passive Vent operates entirely without electricity or any moving parts.

How often should I clean the filter?

It is recommended to check and clean the washable filter at least every 3-6 months, or more frequently if you live in a dusty environment or notice reduced airflow.

Can I close the vent completely?

Yes, the adjustable iris shutter allows you to close the vent completely when maximum airflow is not needed, such as during very cold periods.

What is included in the kit?

Each kit includes an internal grille with a washable filter, telescopic ducting, an exterior hood, a pull cord, screws, wall plugs, and all necessary installation components.

What warranty does this product have?

The Dryzone Telescopic Passive Vent comes with a five-year warranty for long-term assurance.

Troubleshooting

Little to no airflow detected

Ensure the iris shutter is fully or partially open. Check that the interior grille and filter are clean and not blocked. Verify the exterior hood is not obstructed.

Condensation still present

While the vent reduces humidity, other factors like high internal moisture production or poor insulation can contribute. Ensure the vent is correctly sized for the room and that the filter is clean. Consider opening the shutter further or using multiple vents if necessary.

Difficult to adjust shutter

Gently try to move the shutter mechanism. If it feels stuck, check for any obstructions or debris around the shutter area.

Pros and Cons

Pros

  • Requires no electricity or batteries, leading to zero running costs.
  • Silent operation ensures no disruption to living spaces.
  • Helps prevent condensation and mould, improving home health.
  • Adjustable airflow provides flexibility based on weather conditions.
  • Easy to install on external walls with telescopic ducting.

Cons

  • Effectiveness depends on natural air pressure, potentially less powerful than active systems.
  • Requires an external wall for installation.
  • May not be suitable for very large or complex ventilation needs.
  • Requires periodic cleaning of the filter to maintain performance.

Setup, Compatibility & Care

Setup

  1. Determine the optimal location, ideally high on an external wall.
  2. Mark the required hole size on the wall.
  3. Drill the hole through the wall, ensuring it is slightly angled downwards towards the outside.
  4. Insert the telescopic duct into the wall cavity, adjusting its length to fit the wall thickness.
  5. Attach the internal grille (with washable filter) to the duct inside the room and the exterior hood to the duct on the outside wall.
  6. Secure both the internal and external components using the provided screws and wall plugs.
  7. Attach the pull cord to the internal grille if desired for manual adjustment.

Compatibility

This vent is designed for installation in external walls with thicknesses ranging from the minimum internal duct length to 500 mm.

Care

  • The internal grille features a washable filter. Periodically remove the grille and wash the filter with mild soap and water. Allow it to dry completely before reinserting.
  • Ensure the exterior hood remains clear of obstructions like leaves or debris.
  • No electrical connection or mechanical maintenance is required.
