Radial fans Ebmpapst K3G280, R3G280, R2E280, R4E280

size 280 mm AC, RadiCal and RadiPac

1. Description of models K3G280, R3G280, R2E280, R4E280

RadiCal and AC fans K3G280, R3G280, R2E280, R4E280 impellers 133 - 630 mm, made of high-tech composite material with efficient GreenTech EC motors that allows you to create high fan speed at high pressure.Fans have impellers with backward curved blades for working without housing, which gives - optimal flow with low air loss through the impeller.The new engine in GreenTech EC technology with integrated control electronics designed for installation in a variety of sizes - from 190-250 mm the same mounting dimensions as the wheels with an induction motor, EC fan but reaches much higher air performance than an identical version of AC.New features for use in ventilation and air-conditioning, AC models can be replaced with GreenTech EC without increasing the cost of the equipment, but at the same time to achieve high productivity, reduced noise and lower power consumption.

2. When selecting a fan for a specific application, these parameters play an important role:

Air flow with given back pressure Voltage supply, divided into DC and AC voltage (1~, 3~) Noise generation Efficiency Available mounting space Checklist Part designation / type Quantity needed Field of application Ambient conditions (humidity, temperature, climate) Impeller diameter Air flow Back pressure Voltage supply
