## Summary description

Industrial ventilation check valve airRoxy model 110×550 designed to prevent backflow in duct systems. Suitable for use in HVAC and industrial exhaust installations, it provides reliable one-way airflow control, reduces contamination and drafts, and helps maintain system efficiency. Compatible with circular ducts of corresponding diameter and length specification.

## Long description

The airRoxy Check Valve 110×550 is a one-way backflow prevention device designed for industrial ventilation and HVAC exhaust systems. Built to fit circular ducts matching its diameter and length, this check valve allows airflow in the intended direction while preventing reverse flow, reducing contamination and unwanted drafts. The product is intended for installations where maintaining directional airflow and protecting system components from backflow are important for operational efficiency and air quality control.
Advantages
This check valve offers straightforward mechanical operation to ensure one-way airflow without the need for electrical power or complex controls. Its construction minimizes pressure loss while providing reliable sealing against backflow. The design is suitable for integration into ductwork installations and helps reduce the ingress of contaminants and odors, contributing to more stable ventilation performance over time.
Suitable for (tasks / use cases)
Industrial exhaust and ventilation systems requiring backflow prevention
HVAC installations with circular ductwork matching the valve dimensions
Workshops, factories, and commercial kitchens where directional airflow control is necessary
Applications aiming to reduce drafts and prevent contamination of duct networks
When it may not be suitable
This check valve is intended specifically for circular ducts that match its diameter and length; it will not be suitable for rectangular ducts or systems with different dimensional requirements. It is a passive mechanical device and does not provide active flow control, filtration, or noise attenuation; systems needing those functions will require additional components.
Key specifications
Type: Mechanical one-way check valve for ventilation
Shape: Designed for circular duct installation
Nominal dimensions: 110 mm diameter × 550 mm length
Function: Backflow prevention with minimal pressure drop
Typical applications: Industrial and commercial ventilation and exhaust
How to use
Install the valve inline within the circular duct section where backflow prevention is required, ensuring the flow arrow or orientation marking aligns with the intended airflow direction. Secure the valve to adjacent ducting according to standard ductwork fastening methods and verify that seals and joints are tight to prevent leakage. After installation, test the system to confirm that air moves freely in the forward direction and that no reverse flow occurs under expected operating conditions. Perform routine inspections to check for mechanical wear or obstruction that may affect sealing.
What to consider before purchase
Confirm duct internal diameter and available insertion length match 110 mm × 550 mm dimensions
Ensure the valve material and construction are compatible with the operating environment (temperature, humidity, particulate load)
Consider whether additional components (filters, dampers, silencers) are needed for your system
Verify that a passive mechanical check valve satisfies regulatory and performance requirements for your installation
Usage recommendations
Position the valve so its moving elements can operate freely and avoid installing near inline fans or turbulent fittings that may cause premature wear. Schedule periodic visual checks and remove any accumulated debris; replace the unit if mechanical performance degrades to maintain reliable backflow prevention.
