Check valve airRoxy Klapa zwrotna 100 DRIM PLANET by airRoxy (model 07-200)

airRoxy Klapa zwrotna 100 DRIM PLANET by airRoxy (model 07-200) is a compact check valve engineered for Ø100 ventilation ducts. The valve is intended to prevent reverse airflow in circular duct systems, helping to maintain unidirectional ventilation and protecting fans and other equipment from backdrafts. Designed for straightforward installation in residential and light commercial ventilation lines, this one-way valve is suitable where a reliable non-return function is required.

Advantages

The check valve offers a simple mechanical design that requires no external power and provides consistent backflow prevention with low airflow resistance. Its compact circular form factor fits standard Ø100 ductwork and supports easy integration into existing ventilation systems. The valve is corrosion-resistant and designed for continuous operation in normal indoor environments, reducing maintenance needs and preserving system efficiency.

Suitable for

• Residential bathroom and kitchen exhaust ducts
• Apartment and small-office ventilation lines
• Supply and extract branches where backdraft prevention is needed
• Retrofit projects to add non-return functionality to circular ducts

Key specifications

• Nominal duct diameter: 100 mm (Ø100)
• Function: one-way (non-return) airflow control
• Design: circular inline check valve suitable for round ducts
• Material properties: corrosion-resistant construction suitable for indoor ventilation
• Operation: passive mechanical flap for low pressure-drop performance

How to use

Install the valve inline in the circular duct so the flap opens toward the intended airflow direction. Secure the valve using appropriate clamps or duct connectors and ensure airtight joints to prevent leakage. Verify correct orientation before permanent fixation and test the system at normal operating flow to confirm the flap opens and closes as expected. Periodically inspect the valve for dust buildup or obstruction and clean as needed to maintain performance.

Usage recommendations

Place the valve downstream of fans or exhaust points where backflow might occur, avoid installing in locations exposed to heavy contaminants or excessive moisture without additional protection, and follow local ventilation codes for duct sealing and mounting. Regular visual checks during scheduled maintenance will help ensure reliable operation.
