Product Overview
Engineered to combat excess humidity, our extraction fans proactively manage moisture in high-humidity zones such as bathrooms, laundry rooms, restrooms, and enclosed pool areas. Designed with scalable capacities, these units adapt to spaces ranging from compact washrooms to large-scale indoor aquatic facilities. Available in both exhaust and inline configurations, their primary objective is to channel moisture-laden air outdoors via duct systems, ensuring balanced indoor air quality and structural integrity.

Key Advantages

1. Durable Construction & Simplified Setup
   A corrosion-resistant all-metal housing streamlines air outlet installation while ensuring long-term resilience. Pre-assembled mounting brackets enable seamless ceiling integration and alignment with existing ductwork.

2. High-Efficiency Capacitor Motor
   Built with a capacitor-enhanced motor, the fan delivers consistent performance, extended operational lifespan, and reduced energy consumption.

3. Advanced Safety Mechanisms
   Integrated overheat protection automatically shuts down the unit during thermal anomalies, prioritizing user safety and equipment longevity.

4. Maintenance-Optimized Design
   Tool-free twist-lock duct connectors and modular components simplify upkeep, allowing quick access for cleaning or part replacements.

General assembly Drawing

Installation Procedure
Step 1: Structural Frame Preparation
Construct a reinforced rectangular frame using load-bearing anchors, ensuring rigid fixation to ceiling joists for maximum stability.

Step 2: Enclosure Mounting
Secure the fan housing to the pre-installed frame using anti-vibration fasteners, minimizing operational noise and enhancing durability.

Step 3: Duct Connectivity
Align the ventilation duct collar’s directional indicator with airflow requirements. Engage the bayonet-style locking mechanism to the cabinet’s outlet port, ensuring airtight sealing and optimal airflow efficiency.
