Axial fans

FN SERIES

APPLICATIONS

Condensing circuits of large refrigeration units
Cooling circuits for welding machines, dryers and air compressors
Can be used to blow air into or out of industrial buildings

TECHNICAL DETAILS

7 milled blades
External-rotor motor
Wiring diagram on the back of the terminal-box cover
Operating temperature 70 °C

NOTE

see the attachments for complete data.

Where the ERP standard is not met, you will be offered a replacement fan.

DESCRIPTION

ECBlue electronically controlled axial fan from 250 to

1000 mm diameter; 100% adjustable speed that can be optimised with
a speed controller. Possible applications: air conditioning, refrigeration,
heat pumps and transformer cooling.
The advantages of the EC Blue series are high efficiency with minimal
power consumption and a very low noise level, thanks also to
the innovative blade shape and unique design.
– Complete with grille and basket
– All suction versions
– Flow rate and maximum speed
– Controller available on request

SMALL-DIAMETER AXIAL FANS

DESCRIPTION

Small-diameter axial fans for moving air in automation, servo-ventilation, electrical panels and for cooling electronic circuits.
Maximum operating temperature 60 °C.

FAN for refrigerators, without grille

LIQUID MIXER AND MOTORS FOR TANGENTIAL FANS

Single-phase external-rotor 230 V 50 Hz motors for special applications,
liquid mixers and tangential fans.
An even wider range available for pellet stoves

TECHNICAL DETAILS

External-rotor axial fans are especially suitable for moving air because they are very quiet, electrically efficient and start softly with a low peak current.

Protection class

IP44–IP54, class F

Maximum operating temperature

-20 °C / +50 °C

FIELDS OF USE

Axial fans are used in the following main areas

Condensing circuits of large refrigeration units
Spare parts for cooling circuits of welding machines and dehydrators
Spare parts for extraction and ventilation plants

OPERATING DETAILS

High-efficiency axial fans are used where large volumes of air at medium or low pressure must be handled.

More precisely, they are fitted in galvanised sheet ducts for ventilation, cooling or drying in various types of system.

NOTE

When choosing the fan and its performance curves, contact our sales department. The fan will be sized to your needs and you will be sent a customised technical data sheet.

ACCESSORIES ON REQUEST

DESIGN FEATURES
High-efficiency axial fans are used where large volumes of air at medium or low pressure must be handled.

HOUSING

The housings of the high-efficiency axial fans are made of hot-dip galvanised steel and electrostatically painted with synthetic powder resin.

FANS

The high-efficiency axial fans have aerodynamically profiled blades (sizes 200 to 300 in painted galvanised sheet steel; sizes 315 to 630-6 in plastic and 630-4 to 1000 in aluminium).

The fans or blades are mounted directly on the rotors of external-rotor motors. The motor–fan unit is balanced to grade G 2.5 according to DIN/ISO 1940.

ELECTRICAL CONNECTION

The motors have a side cable. The electrical connection is made through an IP44 terminal box supplied with the motor.

GENERAL CHARACTERISTICS

(Codes 0401076 – 0401071 – 0401072 – 0401073 – 0401074 – 040105)

Made of black cast aluminium, with non-flammable polycarbonate blades, on ball bearings.

Each fan is designed so that the windings do not burn out when the motor is blocked. The non-flammable material also gives greater safety.

APPLICATIONS

Cooling of control units, control panels, computers etc.

TECHNICAL DETAILS

Single-phase motor 220–230 V 50–60 Hz.

Operating temperature -20 °C to +80 °C.

GENERAL CHARACTERISTICS

(Codes 0401090 – 0401091 – 0401092 – 0401093)

Made of black non-flammable polycarbonate, with blades on sintered, impregnated bushes. Each fan is designed so that the windings do not burn out when the motor jams. The non-flammable material also gives greater safety.

APPLICATIONS

Cooling of control units, control panels, computers etc.

TECHNICAL DETAILS

DC motor 24 V

Operating temperature -20 °C to +80 °C.

Packaging
