HON&GUAN Ventilation Solutions Overview

Vent Hose Series Description
PVC Dryer Vent Hose Durable, lightweight PVC hose offers a smooth interior for easy airflow with basic insulation and light‑blocking properties, ideal for short, flexible dryer‑vent runs.
Double Layer Aluminum Foil Duct Constructed from two concentric layers of aluminum foil reinforced with a steel‑wire helix, this hose delivers superior heat resistance, puncture durability, and minimal lint buildup.
Semi Rigid Vent Hose Semi‑rigid metal duct combines the airflow efficiency and lint resistance of rigid ducting with moderate flexibility, making installation simple while meeting building‑code requirements.
Air Conditioning Exhaust Hose Flexible exhaust hose with internal steel support coil for portable AC units, designed to expel heat and humidity efficiently through windows via twist‑and‑snap installation and adjustable lengths.

Product Comparison: Inline Fan vs Exhaust Fan

Feature Inline Fan Exhaust Fan
How it works Installed inside ductwork, moving air through pipes. Mounted on walls or ceilings, directly expels air from the space.
Applicable scenarios Suitable for long ducts or large spaces like grow tents and industrial environments. Best for smaller spaces, such as bathrooms or kitchens.
Airflow and efficiency Strong, steady airflow across long distances. Direct airflow but may be less efficient for longer distances.

Usage Scenarios

Application Description
Residential Laundry Rooms A dryer vent hose efficiently channels hot, moist air and lint from residential dryers to the exterior, preventing indoor humidity, mold growth, and reducing fire risk.
Portable Air Conditioner Venting Connects a portable AC unit to a window or wall kit to expel hot, humid air outside for more efficient cooling and dehumidification.
Installation for  Duct Fan Serves as the flexible link between an inline duct fan and existing ductwork, ensuring airtight airflow and easy fan placement.
