Product Overview

High-performance ventilation units efficiently extract moisture-saturated air from high-humidity zones, including bathrooms, laundry rooms, restrooms, and indoor swimming pools. Engineered with scalable airflow capacities, these systems adapt seamlessly to spaces of all sizes—from compact residential washrooms to expansive commercial pool enclosures.

Available in versatile configurations such as direct-mounted exhaust fans and duct-integrated in-line models, all variants prioritize a singular objective: redirecting excess humidity outdoors via ductwork to maintain balanced indoor air quality.

Key Advantages

• Premium Construction: Full-metal housing ensures durability and simplifies integration with air outlets.
• Reliable Performance: Capacitor-driven motor guarantees extended operational lifespan with minimal maintenance.
• Safety Assurance: Built-in thermal overload protector prevents overheating, enhancing user safety.
• Adaptive Design: Compatible with ceiling-mounted installations and duct/pipe connectivity, enabling streamlined installation and maintenance.
• User-Centric Features: Pre-adjusted mounting brackets and tool-free access panels simplify cleaning and servicing.

Product Installation Method

Step 1: Construct a rigid ceiling-mounted frame using corrosion-resistant materials, ensuring structural stability.

Step 2: Attach the fan enclosure or housing unit to the pre-assembled frame, securing it with vibration-dampening fasteners.

Step 3: Align the duct connector with the directional arrow (indicating airflow path) and lock it onto the cabinet’s exhaust port using a twist-to-lock system for airtight sealing.
