Ultraflex AT444 adapter T 100 mm (4") wlot, | Ultraflex 62419R

Ultraflex AT444 is a T-shaped duct adapter designed to split the airflow in ventilation and extraction systems using ducts with a nominal diameter of 100 mm (4"). Its design features one 100 mm inlet and two 100 mm outlets, allowing parallel supply or extraction of two branches from one main duct of the same diameter. This type of element is installed inline in a round duct—typically by inserting the socket ends into flexible or rigid ducts and securing them with clamps, aluminum tape, and/or a gasket to ensure airtight connections. The T adapter 100/100/100 is suitable for local exhaust systems, dust/light chip extraction, workshop and hobby installations (e.g., woodworking), and small supply-exhaust ventilation systems, wherever there is a need to branch a 100 mm duct without diameter reduction. Because the diameter remains the same on all three spigots, flow division and possible balancing of hydraulic resistances in the branches (dampers, different duct lengths) should be considered to avoid uneven flows. The T adapter can be installed in any position, maintaining the flow direction from the inlet spigot to the two outlets. Properly routed straight sections before and after the tee reduce turbulence and pressure drops. The product is identified as AT444, with the Ultraflex catalog number 62419R.

SKU (catalog number): 62419R

Model/designation: AT444

Product advantages:

- Flow division without reduction—all spigots with 100 mm diameter ensure system consistency of 4". - Easy installation on standard Ø100 mm ducts thanks to socket spigots. - Universal use in ventilation and local exhaust in small and medium installations. - Enables easy parallel supply of two points from one main duct. - Maintaining the 4" standard facilitates accessory selection (clamps, dampers, connectors). - Can operate in any mounting position, easing duct routing in limited spaces. - Easy integration with 100 mm dampers for flow balancing in both branches. - Reduces local losses compared to branches requiring diameter reduction.
