Double Deflection Curved Grille

Double Deflection Curved Grille Manufacturer in India – Aluminium HVAC Grille for Round Duct Systems

Our Double Deflection Curved Grille is a specially engineered air distribution component designed for mounting on round and elliptical duct systems used in modern HVAC installations. As a reliable Double Deflection Curved Grille manufacturer in India, we provide high-quality aluminium air grilles that ensure efficient airflow control, durability, and superior performance in commercial, industrial, and residential ventilation systems across India.

Manufactured using premium grade extruded aluminium profiles, this curved HVAC grille in India offers excellent corrosion resistance, structural rigidity, and long service life. The curved design allows it to perfectly fit on rigid round or elliptical ducts, making it an ideal solution for exposed duct HVAC systems commonly used in commercial buildings and industrial facilities.

Designed for Round and Elliptical Duct Applications

Unlike standard flat air grilles, the Double Deflection Curved Grille is specially designed to match the curvature of circular or elliptical ducts. The grille curvature is formed using precision tools that ensure accurate alignment with the duct diameter. Standard diameters range from 200 mm to 600 mm, while non-standard diameters can also be manufactured based on project requirements across India.

This design ensures a secure and seamless fit on round duct systems, providing both functional efficiency and aesthetic appeal in modern HVAC installations.

Dual Blade System for Precise Airflow Control

The Double Deflection Curved Air Grille features two sets of parallel aerofoil blades designed for flexible air distribution. The front set of blades is mounted horizontally, while the rear set is positioned vertically. This dual blade configuration allows airflow to be adjusted in both horizontal and vertical directions.

Each blade can be manually adjusted and individually positioned, allowing HVAC engineers to control air throw and distribution based on room layout and ventilation needs. This feature ensures uniform air circulation and improved indoor comfort in air-conditioned environments.

Because of this advanced design, the Double Deflection Curved Grille in India is widely used in supply air and return air applications within centralized HVAC systems.

Quiet and Smooth Operation

The frame is separated from the aerofoil deflection blades using durable nylon bushings. This assembly technique ensures smooth blade movement and eliminates vibration or rattling noise during operation. As a result, the grille provides silent performance even at higher air velocities.

This makes the Curved HVAC Grille suitable for installations in offices, hospitals, hotels, conference rooms, educational institutions, and other environments where quiet operation is important.

Integrated Opposed Blade Damper for Airflow Control

The grille is equipped with an opposed blade damper rigidly fixed using rivets. The damper blades can be gear operated from the face opening of the grille, allowing easy adjustment of airflow volume. This feature helps HVAC technicians perform air balancing efficiently without removing the grille.

The damper system ensures precise control over the air stream, improving the performance and energy efficiency of HVAC systems across India.

Durable Aluminium Construction

Our Aluminium Double Deflection Curved Grille in India is built with corrosion-resistant extruded aluminium that ensures long-term durability even in humid and coastal environments. The frame is constructed with 45° mitered corners and reinforced corner cleats, providing both structural strength and a clean architectural finish.

The robust yet lightweight aluminium construction also ensures easy installation and minimal maintenance.
