Description

Airflow Airflex ISO 160mm 90° Insulated Duct Bend with Male Connector

The Airflow Airflex ISO 160mm 90° Insulated Duct Bend (90000467) is a durable, pre-insulated ducting component designed for mechanical ventilation systems, including Mechanical Ventilation with Heat Recovery (MVHR).

Designed to provide a 90-degree change in ductwork direction, this insulated elbow allows ventilation systems to navigate corners and obstacles while maintaining thermal insulation and efficient airflow.

Manufactured from high-quality, vapour-tight and anti-static expanded polyethylene (EPE), the Airflex ISO bend helps minimise heat loss and reduce the risk of condensation forming within ventilation ductwork.

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

Key Features

  • 160mm Diameter: Compatible with Airflow Airflex ISO 160mm insulated ducting systems.

  • 90° 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 an internal plastic connector for easy installation.

  • Lightweight & Durable: Manufactured from tough, anti-static expanded polyethylene (EPE).

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

  • Sound-Absorbing Properties: Helps reduce noise transmission through the ducting system.

  • Flame Retardant: Classified as B1 according to Airflow's product specifications.

  • 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.
