Expanded Product Description
This VF-M series fan focuses on three real-world needs: effective moisture removal, easy installation, and long-term reliability in humid indoor spaces. The front shutter panel design provides a tidy, modern appearance, making it suitable for apartment bathrooms, hotel washrooms, and retrofit upgrades where aesthetics matter.
The housing uses LG ABS plastic, a practical material choice for indoor ventilation products because it is lightweight, durable, and well-suited to everyday humidity exposure. A press-circle design supports safer and more convenient handling during installation and maintenance. For airflow control and comfort, the fan includes a back damper that helps reduce backflow when the unit is off—and can assist in limiting insect intrusion along the duct path (often described as “anti-mosquito”).
Depending on the project specification, configurations may include an Italian hot switch option and a synchronous motor option, helping contractors match local requirements and user preferences.
What Is a Front Shutter Panel Bathroom Ventilating Fan?
A front shutter panel bathroom ventilating fan is a mechanical exhaust device designed to remove humid air and odors from bathrooms. The “front shutter panel” style emphasizes a clean front face while covering the exhaust opening, supporting a neat finish for ceilings or walls. Compared with passive ventilation, a powered fan delivers predictable airflow, which is especially important in windowless bathrooms or high-use washrooms.
Key Features and Benefits
LG ABS Plastic Housing for Practical Durability
The fan uses LG ABS plastic for the housing, helping keep the unit lightweight and durable. ABS is widely used for indoor electrical housings and ventilation products due to its balance of strength and form stability.
Back Damper: Helps Reduce Backflow and Supports Cleaner Airflow
The integrated back damper helps reduce reverse airflow through the duct when the fan is not running. This supports better comfort and airflow behavior, and may help reduce insect intrusion along the duct path in certain environments.
Press-Circle Design for Safer, More Convenient Handling
The press-circle design is intended to improve convenience during installation and servicing—especially helpful for contractors working in tight ceiling spaces.
Motor Options for Different Project Requirements
The series highlights a professional motor design for stable operation. For certain configurations, an Italian hot switch and a synchronous motor option are available, providing flexibility for different markets and project specifications.
Technical Specifications
Choose the model based on airflow requirement, energy preference, and installation cutout size. All listed models share 220–240V rated voltage and 50–60Hz frequency.
| Model | Rated Voltage (V) | Frequency (Hz) | Power (W) | Air Delivery (m³/h) | Hole Size / Cutout (mm) |
|---|---|---|---|---|---|
| VF-M4 | 220–240 | 50–60 | 12 | 80 | Ø105 |
| VF-M5 | 220–240 | 50–60 | 15 | 150 | Ø125 |
| VF-M6 / VF-M6S | 220–240 | 50–60 | 20 | 250 | Ø155 |
| VF-M6M / VF-M6T / VF-M6I | 220–240 | 50–60 | 28 | 250 | Ø155 |
Selection tip: for larger bathrooms, higher humidity loads, or frequent use, choose higher airflow models (e.g., VF-M6 series). Always match the cutout size (Ø105 / Ø125 / Ø155) to your ceiling/wall plan and ducting layout.
Usage Scenarios
The front shutter panel VF-M series is designed for everyday bathroom exhaust needs across multiple building types:
- Residential bathrooms: apartments, condos, and homes needing consistent humidity and odor exhaust.
- Hotels and hospitality: guest washrooms where appearance and reliability are both important.
- Office washrooms: staff restrooms requiring dependable ventilation to improve user comfort.
- Renovations and retrofits: replacing older fans while keeping cutout sizes aligned to the existing ceiling plan.
- High-rise buildings: enclosed bathrooms without windows requiring stable mechanical ventilation.
Who Should Buy This Product?
This product is ideal for B2B procurement and project supply channels:
- HVAC and ventilation contractors: selecting reliable exhaust solutions with clear performance tiers.
- Builders and project contractors: specifying bathroom ventilation for new developments and fit-outs.
- Distributors and wholesalers: sourcing multi-model fan series (VF-M4/M5/M6) for broad market coverage.
- Facility and property managers: upgrading ventilation to reduce humidity complaints and maintenance costs.
- Importers and retail channel operators: looking for modern design, stable specs, and consistent supply.
Comparison: Mechanical Exhaust Fan vs. Passive Ventilation
Passive ventilation methods (windows or passive vents) depend heavily on outdoor conditions and may not remove moisture fast enough after showers. A mechanical bathroom ventilating fan provides predictable airflow, improving moisture control and reducing lingering odors. The VF-M series adds a clean front shutter panel look while still delivering practical airflow for daily bathroom use.
