Air Vent Grille SCHNEIDERE NSYCAG19LP — circular inlet Ø 19 mm

SCHNEIDERE NSYCAG19LP — circular air vent grille with a 19 mm inlet diameter — is designed for controlled supply air in HVAC systems. The compact circular inlet concentrates airflow into a small-diameter opening, making the grille suitable for precision ventilation points in residential and light commercial interiors. Constructed to integrate with ducts and ventilation terminals, this grille is intended for situations where a discreet, targeted air supply outlet is required.

Advantages

The small circular inlet provides a focused airflow pattern that helps direct supply air to specific zones. Its compact size enables installation in limited spaces and close to finishes without occupying significant surface area. The product is compatible with standard ventilation ducts and terminals, offering a simple solution for supplying fresh or tempered air through a limited-diameter opening.

Suitable for

• Residential rooms requiring localized supply air, such as bathrooms, corridors, or utility rooms
• Light commercial spaces where discreet airflow outlets are needed
• Ductwork or ventilation terminals with limited space or small round connection points
• Supplementary supply points for demand-controlled ventilation systems

When it may not be suitable

The grille’s 19 mm inlet diameter limits the maximum volumetric airflow it can deliver; it is not intended as a primary supply for large open-plan areas or spaces that require high air change rates. For systems needing substantial airflow or broad distribution, larger diffusers or multiple outlets will be more appropriate. Also, if integrated noise reduction or adjustable directional louvres are required, this simple circular grille may not provide those features.

Key specifications

• Inlet shape: circular
• Inlet diameter: 19 mm
• Application: supply air for HVAC systems
• Suitable environments: residential and light commercial interiors
• Mounting: designed for integration with ducts or ventilation terminals

How to use

Install the grille into the matching circular opening or duct collar with appropriate fixings and sealing to prevent air leakage. Ensure the inlet aligns with the supply airflow direction and that the grille is secured flush with the mounting surface or terminal. After installation, verify airflow and adjust the HVAC system balancing components as required to achieve the intended supply rate and distribution.

What to consider before purchase

• Confirm the duct or terminal connection diameter matches a 19 mm circular inlet or plan an adapter if needed
• Check the required supply air volume for the target space to ensure a small-diameter outlet is adequate
• Consider placement to avoid obstruction and to provide effective airflow direction
• Verify material and finish compatibility with the installation environment and aesthetic requirements

Usage recommendations

For targeted supply air in small rooms or as a supplementary outlet, use this grille with properly balanced ventilation settings and consider pairing multiple outlets if higher flow or broader distribution is necessary.
