Product Overview

Advanced humidity control systems effectively expel moisture-laden air from high-humidity environments such as bathrooms, laundry rooms, restrooms, and indoor pool facilities. Designed with scalable airflow outputs, these units cater to spatial demands ranging from confined washrooms to large-scale commercial humid zones.

Available in two primary configurations—wall/ceiling-mounted exhaust systems and duct-integrated in-line modules—all variants share a unified purpose: extracting excess airborne moisture and channeling it outdoors via corrosion-resistant duct networks.

Core Benefits

• Industrial-Grade Durability: Full-metal casing ensures robust performance and simplified air outlet integration.
• Extended Operational Life: Precision-engineered capacitor-driven motors deliver silent, energy-efficient operation with minimal wear.
• Proactive Safety Measures: Integrated thermal cut-off system automatically disengages the unit during overheating risks.
• Modular Installation: Pre-configured ceiling mounts and universal duct/piping compatibility enable rapid deployment and hassle-free maintenance.
• Ergonomic Design: Tool-free access panels and snap-fit duct connectors reduce installation time by up to 40%.

General assembly Drawing

Product Installation Method

Phase 1: Structural Preparation
Assemble a reinforced aluminum or galvanized steel frame, anchoring it securely to ceiling joists or beams to ensure load-bearing compliance.

Phase 2: Unit Integration
Mount the fan enclosure onto the pre-fixed frame using anti-vibration brackets, minimizing noise transmission during operation.

Phase 3: Ductwork Alignment
Orient the duct connector according to the embossed airflow directional guide (→), then engage the twist-lock mechanism onto the cabinet’s exhaust port to achieve a hermetic seal.
