Propeller fan RLBF03-4.9-5

ceiling-mountedfor air circulationventilation

Overview
Industrial HVLS (High Volume Low Speed) ceiling fan with PMSM permanent magnet synchronous motor delivering low-speed, high-volume airflow for large-space ventilation, cooling and dehumidification. Designed for workshops, warehouses, farms and gymnasiums. Multiple built-in safety measures and VFD speed control with wireless remote.

Features

• PMSM permanent magnet synchronous motor: efficient, low-noise, low-maintenance
• 6063 aluminum blades (5 or 6 blades option) provide wide-area, soft airflow
• Comprehensive safety: anti-fall steel cable system, blade anti-drop structure, overload protection
• VFD (frequency conversion) drive with wireless remote for stepless speed adjustment
• Knock-down split packaging for reduced sea freight and easy on-site assembly
• Suitable for warehouses, factories, breeding farms, gymnasiums and high-ceiling commercial spaces

Product Description
HVLS fan produces a wide, gentle airflow to improve air circulation, reduce temperature stratification and assist dehumidification in large indoor spaces. Motorized by a PMSM permanent magnet synchronous motor for high efficiency and low noise. Vector VFD drive provides stable control and stepless speed adjustment via wireless remote. Safety features include anti-fall steel cable, blade anti-drop structure and overload protection. Blades are surface-treated (anti-corrosion and oxidation) and powder-coated at high temperature (film thickness ≈ 70 ± 5 µm); blade color and specifications can be customized to project requirements.
