Product Overview
1.1 The RTC series all-aluminum centrifugal rooftop fan adopts a centrifugal impeller, making it suitable for places that require small air volume but relatively high pressure. It is equipped with a single-layer wind cap.
1.2 Classified by impeller diameter, the fan is available in 8 specifications, ranging from 300mm to 1000mm. The air volume range of the series is 900-49,000 m³/h, and the static pressure range is 50-460 Pa.
1.3 To meet different environmental requirements, the fan can be manufactured into an explosion-proof type or an anti-corrosion type. The explosion-proof type is applicable to non-corrosive places containing flammable and explosive gases, while the anti-corrosion type is suitable for environments with corrosive gases.
1.4 To satisfy users' needs for performance adjustment under different working conditions, the fan can be equipped with a two-speed motor to achieve two-level speed regulation. It can also be matched with a variable-frequency motor and a variable-frequency controller for frequency conversion adjustment. It is recommended that the adjustment frequency be locked between 25Hz and 50Hz (to be specified when placing an order).
1.5 According to user requirements, the fan can be equipped with manual or electric adjusting dampers, self-closing shutters, etc. (to be specified when placing an order).
