Ubbink Air Excellent 48C Click-Seal Ring

Ubbink Air Excellent 48C Click-Seal Ring

The Air Excellent 48C Click-Seal Ring is a duct accessory designed for quickly and airtight connecting ventilation ducts and fittings. Thanks to the integrated Click-Seal principle, you create a mechanical connection without the need for tape, sealant, or loose sealing rings. This ensures a reliable joint that seals immediately and contributes to an efficiently operating ventilation system.

Advantages and Features

• Airtight Mechanical Connection: Prevents air leakage between duct sections, enabling the ventilation system to maintain its designed capacity and reducing unnecessary compensation by the fan.
• Low Pressure Loss: The effective sealing minimises additional resistance in the duct system, resulting in lower energy consumption and more stable air volumes per room.
• Quick Installation Without Tools: The Click-Seal design snaps easily into place, saving installation time and reducing the risk of installation errors.
• Lightweight Design: With a net weight of approximately 0.021 kg, it is comfortable to handle, even when installing at height or in confined spaces.
• Certified Quality: The ring is TÜV SÜD certified and classified as Euroclass E for fire reaction, aligning with safe and controlled installation standards.

Performance and Practical Application

An airtight connection directly impacts the efficiency of your ventilation system. Less leakage means the intended airflow actually reaches the room, rather than escaping into ceilings or ducts. Consequently, the fan works less hard, leading to reduced energy consumption and lower noise levels within the ductwork.

The Click-Seal Ring withstands temperatures from -20 °C to 60 °C, making it suitable for a wide range of indoor climates and plant rooms. With a diameter of approximately 103 mm and a height of 62 mm, it fits seamlessly within the 48C system, keeping the duct run compact and organised.

Installation and Maintenance

You install the ring directly into the 48C duct or fitting, after which the joint locks mechanically. Because no additional sealing materials are required, you work cleaner and faster on site. The fixed seal also minimises the risk of drying out or sealant detachment over time.

During maintenance, the connection remains reliably functional without the need for extra inspection points. This makes the system suitable for both new-build and refurbishment projects where airtightness and energy performance are priorities.

With the Air Excellent 48C Click-Seal Ring, you achieve a fast, controlled, and durable duct connection that contributes to a quiet, energy-efficient, and professionally executed ventilation system.
