1. Description of models K3G450, R3G450, R4D450, R4E450
RadiCal and AC fans K3G450, R3G450, R4D450, R4E450 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
