GANR - Non-Return Valve

GANR – Non-Return Valve for Ventilation Systems

The GANR non-return valve is specifically designed to prevent backflow of air within a ventilation or extraction system. It ensures that airflow moves in the intended direction, preventing contamination, pressure loss, and inefficiencies in industrial, commercial, and residential ventilation setups.

Key Features and Benefits:

1. Backflow Prevention for Optimal System Efficiency

The primary function of the GANR non-return valve is to stop unwanted air reversal, which can disrupt airflow balance and cause system inefficiencies. By allowing air to flow in only one direction, it helps maintain proper pressure levels and prevents the ingress of dust, fumes, or other pollutants from external sources.

2. Smart Closing Mechanism with Adjustable Counterweight

The valve is equipped with an inner closing blade that is mounted on a lever system with an adjustable counterweight. This allows for precise control of the closing force, enabling the valve to adapt to different airflow pressures and system requirements. The counterweight mechanism ensures smooth and reliable operation, even in varying ventilation conditions.

3. Foam Insert for Airtight Sealing

To enhance tightness and efficiency, the GANR non-return valve is fitted with a foam insert that provides an airtight seal when the valve is closed. This prevents even minimal amounts of air leakage, ensuring maximum energy efficiency and better system performance.

4. High-Quality, Durable Construction

The valve is manufactured from 0.9 mm galvanized sheet metal, offering high durability and corrosion resistance. This robust construction ensures long-term performance, even in demanding industrial environments with high humidity or temperature variations.

Applications:

The GANR non-return valve is suitable for a variety of ventilation and extraction systems, including:

• HVAC systems in commercial and industrial buildings
• Dust and fume extraction systems in workshops and factories
• Kitchen exhaust and air filtration systems
• Warehouse and storage area ventilation
• Residential ventilation systems where controlled airflow is required

Installation and Maintenance:

The GANR non-return valve is easy to install within round ventilation ducts and can be integrated into existing systems with minimal modifications. Regular maintenance includes checking the counterweight adjustment and ensuring the foam seal remains intact for optimal operation.

With its high-performance design, durable materials, and airtight sealing, the GANR non-return valve is an essential component for ensuring efficient and reliable airflow in any ventilation system.
