Product Overview

Improve the ventilation of your portable air conditioner with the insulated, foldable exhaust hose extension from Kalsten. This flexible extension features a durable insulated jacket and a secure snap-clip attachment system designed to enhance airflow, reduce heat transfer, and protect the hose from dust and wear. Ideal for apartments, RVs, offices, and seasonal use, this extension ensures cleaner, quieter, and more efficient ventilation.

Main Features

  • Insulated Folding Design: The multi-layer construction reduces heat loss and prevents condensation build-up on the outside of the hose while maintaining flexible, stretchable movement for tight spaces.
  • Sturdy Outer Jacket: Durable polyester fabric withstands punctures, tears, and UV exposure for long-lasting protection around the moving ducts.
  • Thermal Inner Lining: Reflective and heat-resistant inner layer improves cooling performance by minimizing heat transfer through the hose.
  • Universal Compatibility: Designed to fit most portable air conditioners and dehumidifiers with standard round hose connections and common adapter types.
  • Secure Snap-Clip Attachment: Included clips secure the jacket to the hose or window adapter, reducing rattling and preventing accidental disconnection.
  • Noise Reduction: Insulation and fabric jacket dampen vibrations from the exhaust hose for quieter operation.
  • Easy Storage and Transport: Collapsible accordion body compresses flat for compact storage when not in use.

Compatibility & Fit

This extension is designed to work with exhaust ducts for portable air conditioners, dehumidifiers, and removable window adapter kits. The flexible accordion shape adapts to slanted ventilation paths and stretches to cover typical diameters of portable air conditioner hoses. Check the hose diameter and adapter style of your unit to confirm compatibility before installation.

Easy Installation

  • Slide the insulated jacket over the existing exhaust hose or align it between the unit and the window adapter.
  • Secure both ends with the included snap clips to prevent slipping and maintain a tight connection.
  • Adjust the length and angle of the accordion to avoid kinks and ensure smooth airflow.
  • No tools required for most installations; can be used as a quick replacement or seasonal upgrade.

Care and Maintenance

Clean the outer jacket with a mild detergent and a damp cloth. Allow the jacket to air dry completely before reattaching. Regularly check the snap clips and seams and replace them if excessive wear is noticed to maintain a tight, efficient seal.
