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. |
