EUROPLAST AV100 Plastic Non-Return Valve for 100mm Ventilation Ducts

The EUROPLAST AV100 is a reliable non-return valve engineered specifically for 100mm diameter ventilation ducts. This component is designed to maintain unidirectional airflow within your ventilation system, effectively blocking the entry of unwanted odors, dust, or cold air from the outside environment when the ventilation fan is not in operation. Constructed from high-quality, durable plastic, it provides a long-lasting solution for both residential and commercial air exchange systems.

Advantages

The primary benefit of the EUROPLAST AV100 is its ability to prevent backdrafts, which significantly improves the efficiency of your ventilation setup. By ensuring that air only moves in the intended direction, it helps maintain a comfortable indoor climate and prevents external pollutants from entering your living or working space. The lightweight plastic construction ensures easy handling and installation, while the robust design guarantees consistent performance over time without the risk of corrosion.

Suitable for

• Residential bathroom and kitchen ventilation systems
• Commercial office air exchange setups
• Preventing cold air ingress in ventilation ducts
• Blocking external odors from entering through ventilation shafts

When it may not be suitable

This valve is designed exclusively for 100mm diameter round ducts and will not fit systems with different dimensions or non-circular profiles. It is intended for standard air ventilation and is not suitable for high-temperature industrial exhaust systems or ducts carrying corrosive gases.

Key specifications

• Compatible duct diameter: 100 mm
• Material: Durable plastic
• Function: Non-return airflow control
• Installation type: In-duct mounting

How to use

To install the EUROPLAST AV100, simply insert the valve into the 100mm ventilation duct. Ensure that the valve is oriented correctly so that the flaps open in the direction of the desired airflow. It can be secured within the ducting using standard ventilation tape or by friction fit, depending on the specific duct material. Once installed, the valve operates automatically based on air pressure, opening when the fan is active and closing when the fan is turned off.

What to consider before purchase

• Verify that your existing ventilation duct has a 100mm internal diameter.
• Ensure there is sufficient space within the duct for the valve flaps to open fully.
• Check if your ventilation system requires a vertical or horizontal orientation for the valve.

Usage recommendations

For optimal performance, inspect the valve periodically to ensure that the flaps remain free of dust or debris that could hinder their movement. Regular cleaning will maintain the efficiency of your ventilation system and ensure the valve continues to seal effectively.
