Expanded Product Description
This ultra-thin panel bathroom fan is built to balance effective exhaust with a clean interior finish. The front panel sits flush and modern, while the internal airflow path is optimized to move humid air out efficiently. In humid rooms, stable ventilation performance is essential—not only for comfort, but also for protecting walls, ceilings, paint, mirrors, and fixtures from long-term moisture exposure.
The fan’s design highlights three practical advantages for real installations: (1) moisture-ready structure (IPX4) for typical bathroom conditions, (2) back damper to help reduce backflow when the fan is off, and (3) professional motor to support consistent operation. For projects needing control flexibility, versions with time delay and an indicator are available to match different user habits and building standards.
What Is an Ultra-Thin Panel Bathroom Ventilating Fan?
A bathroom ventilating fan is a mechanical exhaust device that removes humid, stale air from bathrooms and sends it outdoors through ducting. Compared to relying on windows or passive vents, a powered exhaust fan provides more predictable moisture removal, which is important in high-use bathrooms and enclosed spaces. A panel-style, ultra-thin model offers a sleek appearance and helps match contemporary interior designs while maintaining essential ventilation performance.
Key Features and Benefits
IPX4 Structure for Humid Environments
Bathrooms require components that handle moisture reliably. The IPX4 structure indicates a design intended for wet-room conditions where splashes and humidity are common. This supports long-term stability in everyday bathroom use.
Back Damper: Reduced Backflow and Added Practical Protection
When an exhaust fan is off, air can sometimes flow backward through the duct due to pressure differences. The built-in back damper helps reduce unwanted backflow and can also assist in reducing insect intrusion along the duct path (often referred to as “anti-mosquito” protection in product configurations).
Professional Motor for Stable Performance
A durable motor is the heart of a ventilation fan. A “professional motor” configuration supports stable running, consistent airflow, and reliable daily operation—important for homes, hotels, and commercial washrooms where fans may run frequently.
Control Options for Different Project Requirements
Different buildings require different control methods. This series supports common options including: Standard (basic on/off), Time delay (continues running after switching off to remove remaining humidity), and Indicator (status light for user clarity).
Technical Specifications
Below is the performance table for the VF-G series. Choose the model based on required airflow, power preference, and ceiling/wall cutout size.
| Model | Rated Voltage (V) | Frequency (Hz) | Power (W) | Air Delivery (m³/h) | Hole Size / Cutout (mm) |
|---|---|---|---|---|---|
| VF-G4 / VF-G4T / VF-G4A | 220–240 | 50–60 | 12 | 80 | Ø105 |
| VF-G5 / VF-G5T / VF-G5A | 220–240 | 50–60 | 15 | 150 | Ø125 |
| VF-G6 / VF-G6T / VF-G6A | 220–240 | 50–60 | 20 | 250 | Ø155 |
Model naming note: “T” commonly indicates time delay, and “A” may indicate an indicator version, depending on configuration and order. For project procurement, confirm the exact control option and packaging requirements with our team.
Usage Scenarios
This ultra-thin panel bathroom ventilating fan series is suitable for a wide range of indoor exhaust applications where moisture and odors must be controlled:
- Residential bathrooms: apartments, villas, condos, and family homes where daily showers create recurring humidity.
- Hotels and hospitality: guest bathrooms requiring consistent exhaust performance and a clean, modern appearance.
- Office washrooms: restrooms and staff wash areas where odor removal and air freshness matter for user comfort.
- Renovation projects: replacing older fans with a modern ultra-thin panel design while matching existing duct layouts and cutouts.
- High-rise buildings: where bathrooms often lack windows and need reliable mechanical ventilation for moisture control.
Practical selection tip: choose higher airflow models (e.g., VF-G6 series) for larger bathrooms, higher humidity load, or frequent use, and choose cutout sizes that match your ceiling/wall design and duct plan.
Who Should Buy This Product?
This product is engineered for professional, B2B-driven procurement needs. Typical buyers include:
- HVAC and ventilation contractors: looking for reliable fan options across multiple airflow levels and standard power specs.
- Builders and project contractors: selecting ventilation products for new residential developments and hospitality projects.
- Distributors and wholesalers: sourcing ventilation fan series with multiple variants (standard / delay / indicator) for market coverage.
- Property and facility managers: upgrading bathroom ventilation to reduce moisture complaints and improve tenant satisfaction.
- Importers and e-commerce operators: needing modern panel aesthetics, clear performance specs, and consistent supply.
Comparison: Ultra-Thin Panel Exhaust Fan vs. Passive Ventilation
Passive ventilation (such as leaving a door open or relying on a small vent) often cannot remove humidity fast enough—especially after showers. A powered bathroom ventilating fan actively exhausts moist air, helping reduce condensation and supporting better long-term bathroom maintenance. Compared to older bulky fan designs, an ultra-thin panel style offers a cleaner appearance while still delivering practical airflow performance.

FAQ
Which model should I choose for my bathroom size?
Select based on airflow requirement and cutout size. Smaller bathrooms often work well with VF-G4 (80 m³/h), while medium to larger bathrooms or high-use washrooms may benefit from VF-G5 (150 m³/h) or VF-G6 (250 m³/h). Always align the hole size (Ø105 / Ø125 / Ø155) with your installation plan.
What is the benefit of a back damper?
A back damper helps reduce backflow through the duct when the fan is off. This can improve comfort and support cleaner airflow behavior, and it may also help reduce insect intrusion along the duct path (depending on installation and building conditions).
What does IPX4 mean for bathroom use?
IPX4 indicates the structure is designed to handle typical bathroom moisture conditions where splashes and humidity are present. It helps improve suitability for humid indoor environments compared to non-rated designs.
Do you offer time delay and indicator versions?
Yes. This series includes configurations labeled with different variants (such as time delay and indicator). For procurement, confirm the exact version you need (standard / delay / indicator) with our sales team.
Can this fan be used for hotel or commercial washrooms?
Yes. The series is well-suited for hospitality and light commercial washrooms where consistent exhaust and a clean panel appearance are preferred. Choose airflow and cutout size based on room usage frequency and project specifications.
