General

NAUTILUS SILENCE series fans offer high performance as well as providing
energy savings with their backward curved blade structure and direct coupled
motor assembly. These fans, which have a very wide usage area, increase the
air quality in areas where fresh air and exhaust are needed. Stone wool, which
provides sound insulation between the double-walled body, is used in the fans,
which are easily mounted to ventilation systems and operate very quietly.

Body

The body is manufactured with electrostatic powder paint for corrosion
resistance. It provides regular flow with its snail design. It provides convenient
and easy installation with its compact design.

Impeller

The fan blades are backward curved and sparsely designed, aerodynamically
curved and provide regular flow.

Motor

All models are equipped with an external rotor motor with a closed structure
and are suitable for operation up to a maximum of 40°C.

Control

Fans with single-phase motors can be operated with the on/off switch, while
fans with three-phase motors can be operated directly with the help of the MCC
panel. The speed adjustment of the models with single-phase motors is made by
the speed switch, and the speed of the models with three-phase motors is made
by the frequency inverter

as NOVVES, we offer solutions with our wide range of products for comfortable ventilation, which can be defined as the continuous supply of fresh air to indoor environments, and we create livable spaces for you by providing the necessary air quality. All products are also manufactured to comply with environmental requirements.

General

Roof and duct type fans in the Hummingbird series, in which EC Motors are
used, provide high performance as well as providing energy savings.
It is used to provide air quality and air conditioning control in areas where
exhaust and fresh air are required. Blade and motor maintenance is
facilitated by the maintenance cover on EC Rectangular duct fans. With the
help of a differential pressure sensor with a PI unit, the fans in the series
operate automatically (optionally) according to the need.

Body

The body is made of galvanized sheet. Coating options with epoxy paint
or electrostatic powder paint are also available. The suction and discharge
ports of the EC rectangular duct fan are flanged.

Motor

High efficiency EC single-phase and three-phase external rotor motors are
used.

Impeller

The fan blades are backward curved and sparsely designed,
aerodynamically curved and provide regular flow.

IP Class

All products of this series have IP 54 class protection and F class
insulation
