Spiral Duct Connection Angle Rings
GFI HVAC's Spiral Duct Angle Rings are precision-formed flanges designed for round ductwork connections in spiral duct systems. Made from high-quality galvanized steel, these angle rings ensure strong, leak-resistant joints and are ideal for medium to high-pressure HVAC applications.
Available in various diameters, including standard and custom sizes, they feature punched holes for TEK screw or bolt connection, reducing field labor and installation time. Commonly used in ventilation, air conditioning, and exhaust systems, angle rings provide a durable and economical solution for round duct joining.
The spiral structure promotes smooth airflow with minimal pressure loss, making them ideal for both residential and commercial ventilation applications. Round Spiral Ducts, commonly used in air conditioning and ventilation systems, are valued for their high structural strength and rigidity.
GFI HVAC ensures each duct is precisely formed and tightly sealed to minimize air leakage and maximize system efficiency.
