CROWN Ceiling Mounted Tubular Ventilating Fan APB Series 8 Inch 10 Inch 12 Inch 24W-36W Excellent Low Noise for Residential Application and Efficient Used
The CROWN Ceiling Mounted Tubular Ventilating Fan APB Series provides an energy-efficient, low-noise air turnover and extraction solution designed for ducted ceiling installations in residential, commercial, and light utility environments.
Manufactured by Crown, a trusted brand in electrical equipment and ventilation systems, this ducted ceiling fan series features an integrated side tubular outlet spigot that allows seamless connection to exhaust ducting pipes to effectively route stale air, moisture, steam, and odor out of enclosed spaces.
The APB series offers three versatile sizes to accommodate various room requirements: the 8-inch APB 15, the 10-inch APB 20, and the 12-inch APB 25.
Operating on a standard single-phase 240V 50Hz AC electrical supply, all models run at a consistent 1250 RPM speed while consuming low power 24W (APB 15), 30W (APB 20), and 36W (APB 25).
Air delivery capacities span from 480 m³/min for the 8-inch model, 600 m³/min for the 10-inch model, up to 720 m³/min for the 12-inch variant, ensuring effective ventilation performance across targeted areas.
Engineered with quiet operation in mind, sound levels range between a low 38 dB[A] and 42 dB[A], minimizing acoustic disruption in residential and office settings.
The clean white square front grille integrates smoothly into plasterboard, gypsum, or modular false ceiling layouts.
Recommended for function areas covering 7–15 m³ (APB 15), 15–20 m³ (APB 20), and 20–25 m³ (APB 25), the Crown APB series is an ideal choice for bathrooms, residential kitchens, restrooms, office conference rooms, and store areas.
Delivering reliable daily performance, low-wattage economy, and simplified duct connection, this series offers practical ventilation efficiency for modern interior construction.
