Blauberg - Metal shut-off and non-return valve 150 mm

The non-return valve blocks the passage of air through the suction hoses when the vacuum cleaner is switched off

This Blauberg non-return valve is designed to automatically close air ducts and prevent backflow when the fan is switched off. Ideal for various environments, from homes to indoor cultivation, it helps to maintain optimal airflow and prevent the spread of unwanted odours or moisture.

Features:

• Automatic operation: Automatically closes the ducts when the fan stops working, preventing the re-entry of unwanted air.
• Wide compatibility: Suitable for circular air ducts with diameters from Ø 100 mm up to Ø 315 mm.
• Robust construction: Made of galvanised steel casing for durability.
• Pressure-driven opening: The two aluminium slats open due to the pressure of the incoming air and close automatically via a spring when the flow ceases.

Installation:

1. Vertical positioning: Ensure that the axis of the slats is positioned vertically.
2. Fixingto ducts: The valve is fixed to circular air ducts by means of clamps or using traditional clamps and canvas tape.
3. Direction of air flow: It is essential to install the valve respecting the direction of air flow within the ventilation system. An arrow on the valve indicates the permissible direction of air flow.

Correct positioning for optimal function:

• Locate the arrow printed on the valve that indicates the permissible direction of air flow.
• Make sure that the arrow points in the direction you want the air to flow.
• Install the valve inside the duct taking into account the direction of air flow indicated by the arrow.

Advantages:

• Preventsair backflow: Keeps air moving in the desired direction, preventing unwanted odours and moisture from returning.
• Improves ventilation efficiency: Prevents already extracted air from re-entering the system, ensuring optimal air flow.
• Easy installation: Quick attachment to ducts with clamps.
• Durable construction: Durable materials for long-term reliable operation.

With the Blauberg non-return valve, you can optimise your ventilation system and enjoy a cleaner, more comfortable environment.
