proSELECTA II is a technical selection program that allows you to
configure your own individually designed fan. It provides you with
the opportunity to choose from the entire range of fan types and
their associated options.
Simple and reliable fan selection
Simple and reliable selection
The result from proSELECTA II is the provision of all the technical
data for your fan, including sound level data, dimension
specifications and accessories. Apart from that, as a registered
user, your purchase prices are provided. Additionally fully
dimensioned drawings in dxf format are available, which can be
downloaded and transferred straight into your CAD system.
So that you can be sure. Models and options that are technically
not permissible, are automatically excluded in proSELECTA II. So
there is no chance that you will configure a “wrong” device option.
During the fan selection process, you can choose any of the
standardised ATEX options.
Free registration and many advantages
You can register as a proSELECTA II user with us, which enables us
to offer you faster order processing. What this means for you is:
? The complete configuration of your fan with its associated system
accessories and belt drive layout.意大利MOTOVARIO    TS71B4 0,37 230/400-50 B14 MV    電機
? The possibility to produce fans that operate via a frequency
inverter.
? The option of saving your own fan configuration on our server.
? The opportunity to modify your saved configuration, even over the
phone to your Nicotra Gebhardt representative.

The genovent? in every respect is a premium product:
It’s convincing by its powerful design, its corrosion resistant aluminium casing and multiple other technical
refinements, and what is more, the price of this high
performance fan is astonishing.
The excellent price – quality ratio of the genovent?
The genovent? is saving cash at all levels:
Save money when buying it
J because of extremely high value specification without extra cost
Save money when running it
J because of reducing heat losses.
J because of long lasting maintenance free operation.
Save money when installing and servicing it
J because of easy fitting without special tools.
J by simple screwing down of the casing.

RDA
The technological quality of the genovent?
The research and development department at Nicotra Gebhardt is known for their
sophisticated ideas. A good example is the genovent?, which is full of extraordinary solutions – without asking for extra cost.
J The genovent? can be fitted as easy as plug&play - even when exchanging an
existing unit.
J The inligent design of the genovent? makes it possible to open the fan in a
most simple and cost saving manner: unscrew and ready!
J The back draught dampers protect the fan from intruding snow or rain, and
prevents unnecessary heat losses of the duct system. This is built in, no extra
backdraught damper need be provided.
J A considerable throw of the vertically discharging genovent? is preventing the
roof from dirt deposits and air flow short circuits.
J The integrated sound absorbing lining for RDA 32 and RDM 32 is reducing the
sound level by about 7 dB(A).
J A flexible and precise targeting of the required duty point reduces energy
consumption. As an option we offer energy efficient solutions through voltage
controlled or multi speed motors, through additional frequency inverters or even
through energy saving brushless DC motors.
J genovent? roof fans are also available in ATEX execution acc. to
category 3G.
J RDA genovent? also with integrated pressure regulation or Time control module for applications according to DIN 18017-3 and DIN 1946-6 – for more see
