RadiFit EC centrifugal fans.Compact, efficient, easily upgraded.

Fits, saves and makes sense!
Our RadiFit range of centrifugal fans with scroll housing and backward curved blades is the new system solution for many applications in industry and ventilation technology. Thanks to the highly efficient GreenTech EC motors, it offers high efficiency at high pressures. They are also extremely compact, robust and light. Best of all, RadiFit fans match the standard installation dimensions for fans. This makes installing and replacing them child’s play.
Typical applications in air conditioning
Example: Low profile air conditioning unit
with RadiFit ø 250 mm
In air-conditioned buildings, the warm air is used to adjust the
temperature of the incoming air. In this process, fans convey the air
through the heat exchanger and then through the intake and exhaust
air ducts. Due to strict energy conservation regulations, the fans
must not only be compact and flexibly controllable, but also highly
efficient. Just like our new RadiFit.
Example: Central air handling unit with RadiFit ø 400 mm
Central air handling units use a variety of components such as filters,
heat exchangers, humidifiers and de-humidifiers. The fans have to
convey the air through all these components as well as through a
branched system of ducts, whilst compensating for the high losses of
pressure. At the same time, the system needs to use less space and
allow many rooms to be ventilated according to demand. The solution
comes in the form of our new EC centrifugal fans, which are flexible,
robust and easy to install.
Typical industrial implementation
Example: Generator cooling with RadiFit ø 310 mm
A fan pushes the ambient air through narrow ducts on the generator
in order to cool it. In this application, too, our centrifugal fans show
off all their strengths. The integrated speed control allows the cooling
to be adjusted to the load or heat generation of the generator at any
time. The fan requires very little installation space, however, as
it needs no separate control unit. It also requires no maintenance.

RadiFit GreenTech EC centrifugal fan
In comparison, the RadiFit GreenTech EC centrifugal fan shows
impressive efficiency and compactness. Thanks to the simple
Plug & Play exchange system, running costs and maintenance
work can be greatly reduced.
RadiFit GreenTech EC centrifugal fan
The RadiFit impresses with its compactness and the efficient control
technology of the GreenTech EC motor. With the innovative
Plug & Play solution, operators can easily modernise their system
and save costs over the long term.
Retrofit: replace with highly efficient technology.
Energy efficiency means lower operating costs. Our centrifugal fans
with GreenTech EC technology are so much more advanced than
normal fans, that even retrofitting existing units quickly pays for
itself. Furthermore, our new range has a particularly long service life
and requires no maintenance at all, which results in further cuts
to operating and life cycle costs. Finally, we deliver the fans complete
with housing and installed controlled electronics (VSD). This also
reduces your installation costs to a minimum.
Comparing this to an obsolete belt drive and a flange-mounted motor
makes the difference clear to see. Instead of connecting multiple
components to each other at great effort and expense, RadiFit has
everything integrated already, combined with minimal size and
maximum energy efficiency.

Centrifugal fans with belt drive
and external control electronics need a lot of space and have
high maintenance costs related to wear-and-tear parts. Often,
cheap and inefficient forward curved blowers are used here.
Centrifugal fans with standard AC motor
are complex systems which require a lot of space for drive
and control.

With the GreenTech EC solution from ebm-papst, you get a complete
system, consisting of a motor, impeller and integrated variable speed
drive. All from one source and ready configured. That means no extra
components and simple commissioning.
Fans are often assembled from various different components,
mostly from different manufacturers. The user then has to ensure
that these components fit together. This costs time and money,
as well as being very stressful.

The system solution for every power range.
The performance measurements for all fans are conducted on
cutting edge chamber test rigs as per ISO 5801. The entire fan unit,
consisting of the motor, the control electronics, the impeller and
the housing, is measured at different load levels. This provides us
with reliable data, meaning that when you are choosing your fans,
you can count on these values being met. This rules out any nasty
surprises when commissioning the fans. The measurement data
form the basis for the design program available on request. Use this
software to calculate expected operating costs or conduct a cost
analysis for the life cycle.

The RadiFit with mounting bracket is supplied with a connection flange on the outlet side and fastening feet mounted in the 90° housing position.
The feet can be easily moved according to the housing positions at 0° and 270°. At 180°, the flange is preferred for mounting.
The RadiFit is also delivered with mounting frame and discharge side connection flange for sizes 310 and above.
RadiFit with frame and flange
Two dimension systems have become established in recent years for housing fans. Imperial measurements in inches and metric measurements
in line with DIN 323, norm series R20. The RadiFit fan housing sizes use metric dimensions and are therefore also suitable for 1:1 replacement in
existing systems. Simple, fast, efficient.
