Description

Airflow Airflex ISO 200mm 45° Insulated Duct Bend with Male Connector

The Airflow Airflex ISO 200mm 45° Insulated Duct Bend (90001277) is a durable, pre-insulated ducting component designed for mechanical ventilation systems, including Mechanical Ventilation with Heat Recovery (MVHR).

Designed to provide a smooth 45-degree change in ductwork direction, this insulated elbow allows ventilation pipework to navigate around obstacles while maintaining effective thermal insulation and efficient airflow.

Manufactured from lightweight, durable insulating foam with anti-static properties, the Airflex ISO bend helps minimise heat loss and reduce the risk of condensation forming within ventilation ductwork.

Ideal for installations in unheated areas such as lofts, roof spaces and service voids, the bend is supplied with one internal plastic male connector, allowing straightforward installation with compatible Airflow Airflex ISO components.

Key Features

  • 200mm Diameter: Designed for compatible Airflow Airflex ISO 200mm insulated ducting systems.

  • 45° Bend: Allows ductwork to change direction around corners and obstacles.

  • Pre-Insulated Construction: Helps minimise heat loss and reduce condensation risk.

  • Male Connector Included: Supplied with one internal plastic connector for convenient installation.

  • Lightweight & Durable: Tough, anti-static construction for reliable performance.

  • Smooth Internal Surface: Helps minimise airflow resistance and supports efficient ventilation.

  • Sound-Absorbing Properties: Helps reduce noise transmission through ventilation ductwork.

  • Quick Installation: Designed for straightforward assembly with compatible Airflex ISO components.

  • Versatile Application: Suitable for MVHR and mechanical ventilation installations.

Frequently Asked Questions

  • What’s the difference between thermal ducting and insulated standard ductwork?

    Thermal ductwork has insulation incorporated into the duct system, while standard ductwork can be insulated separately after installation. Both approaches can reduce heat transfer and condensation risk when correctly specified.

  • Does thermal ducting come pre-insulated?

    Many thermal duct systems are supplied with insulation already incorporated into the product. Always check the individual specification because construction and insulation performance vary.

  • Do I need thermal ducting if my loft is already insulated?

    Potentially, ducts outside the heated building envelope can still experience significant temperature differences, so suitable duct insulation may still be required.
