CATA B10 PLUS/C E-100 Non-Return Valve

The CATA B10 PLUS/C E-100 non-return valve is a high-quality ventilation accessory engineered to optimize the performance of your exhaust system. Designed specifically for 100mm diameter ducts, this component effectively prevents backdraft, ensuring that air flows in only one direction. By stopping external air, odors, and dust from entering your living space through the ventilation shaft, it maintains a cleaner and more comfortable indoor environment.

Advantages

This non-return valve offers a reliable solution for maintaining unidirectional airflow in residential and commercial ventilation systems. Its durable plastic construction ensures longevity and resistance to environmental factors within the ductwork. By preventing the return of air, the valve significantly improves the efficiency of your exhaust fan, allowing it to operate without fighting against incoming drafts. The simple design facilitates easy integration into existing 100mm ventilation setups, providing an immediate upgrade to your air management system.

Suitable for

• Residential bathroom ventilation systems
• Kitchen exhaust setups requiring backdraft protection
• Small office ventilation ducts
• Preventing cold air ingress in winter

When it may not be suitable

This valve is not intended for use in industrial environments with high-temperature exhaust gases or aggressive chemical vapors that could degrade the plastic material. It is also not suitable for systems requiring fire-rated dampers or those with duct diameters other than 100mm.

Key specifications

• Diameter: 100 mm
• Material: Durable plastic
• Compatibility: Standard 100mm ventilation ducts
• Function: Unidirectional airflow control

How to use

Installation of the CATA B10 PLUS/C E-100 non-return valve is straightforward and requires no specialized tools. Simply insert the valve into the 100mm ventilation duct or directly behind the exhaust fan housing. Ensure that the flap mechanism is oriented correctly to allow air to exit the room while blocking any return flow. Once positioned, verify that the flap moves freely without obstruction to ensure optimal performance.

What to consider before purchase

• Verify that your existing ventilation duct has a 100mm diameter.
• Ensure there is sufficient space within the duct or fan housing for the valve mechanism.
• Check the orientation of your current exhaust system to confirm the valve will be installed in the correct direction.

Usage recommendations

For the best results, inspect the valve periodically to ensure it remains free of dust or debris that could hinder the movement of the flap. Regular maintenance ensures the valve continues to provide an effective seal against backdrafts.
