Product Overview

Transform your indoor environments with precision-engineered ventilation systems, designed to combat humidity in high-moisture zones like bathrooms, laundry rooms, and indoor aquatic facilities. Our range offers adaptable solutions for spaces of all scales—from compact powder rooms to large-scale leisure complexes. Featuring both direct-mount and in-line configurations, these units deliver unmatched efficiency in capturing airborne moisture and odors, redirecting them outdoors via low-profile duct networks to preserve indoor air purity and comfort.

Key Innovations

1. Whisper-Smart Acoustics
   Advanced noise-dampening technology reduces operational sound to <25 dB, enabling near-silent air exchange without compromising airflow rates (up to 150 CFM).

2. Intelligent Humidity Management
   AI-optimized airflow algorithms dynamically adjust ventilation intensity based on real-time moisture detection, balancing energy efficiency with rapid dehumidification.

3. Industrial-Grade Construction

   • Corrosion-Resistant Housing: 304-grade stainless steel casing with powder-coated finish ensures longevity in high-humidity environments.
   • Self-Maintaining Motor: Permanently lubricated, thermally protected dual-ball bearing motor supports 24/7 operation with a 50,000-hour lifespan.

4. Modular Installation System

   • Pre-engineered mounting brackets (adjustable 18–24” span) simplify ceiling integration.
   • Tool-free duct connectors with gasket-sealed twist locks eliminate air leakage risks.

General assembly Drawing

Product Installation Method

Stage 1: Structural Reinforcement
Construct a load-rated aluminum alloy frame, anchored to ceiling support beams using galvanized steel fasteners (shear strength ≥800 lbs).

Stage 2: Unit Assembly
Secure the fan enclosure to the frame via anti-vibration isolators, ensuring ≤0.5 mm alignment tolerance for noise-free performance.

Stage 3: Duct Integration
Align the duct adapter with the embossed airflow vector (→), then engage the dual-stage twist-lock mechanism to achieve an IPX4-rated seal at the cabinet’s exhaust interface.
