380 and 480V.

The maximum fluid temperature is +120°C.

Note

When installing EC motors, ensure that RCDs of type class: B or B+ are present in the circuit.

5.2. GB, GBG and GBV with AC motor

Speed control options:

• 400V IE2/3 motors with frequency inverter with built-in sine filter control

5.7. Fan and Motor Data

• Max. Temperature of transported air, Max. Ambient temperature, Sound pressure level -> See data sheet, available in

our online catalogue.

• Voltage, amperage, protection class, weight -> See type plate

• The motor data can be found on the type plate of the motor or in the technical documentation of the motor

manufacturer.

• The data on the type plate of the fan apply to "normal air" according to ISO 5801.

5.8. Intended use

• The fans are intended for installation in ventilation systems. The fans can be installed both in a duct system and free-

intake via inlet connection pieces and a contact guard grille on the intake side. Free blowing via contact protection

grille is also possible.

• The fan is suitable for conveying clean air.

• The maximum permissible operating data on the type plate apply to an air density of 1.2 kg/m³ (NN) and a maximum

humidity of 80%.

Improper use is mainly when the fan is used in a way other than described. The following examples are contrary to the

intended use and dangerous:

• Conveying explosive and

flammable media

• Conveying aggressive media

• Conveying extremely contami-

nated air without pre-filtering

• Operation in potentially

explosive atmospheres

• Operation without a duct

system or guard grille

• Operation with sealed air

connections Air connections

• Outdoor installation without

weather protection

Note

We generally recommend pre-filtering the extract or supply air before the fan

For example, with a filter box or an activated carbon module, see WALPOL-Product range

6. Type plate and type code

Every fan has a type plate.

Please compare the fan type/data with the version you ordered to avoid misunderstandings or wrong deliveries.

7. Accessories

We recommend original accessories from Walpol. For information, please contact Walpol.

8. Installation

Warning: Risk of impact from falling fan or fan parts.

• Check the surface for load-bearing capacity before installation.

• Take all static and dynamic loads into account when selecting lifting equipment and mounting parts.

General safety instructions

• Installation may only be carried out by appropriately qualified persons, for details, see Table 1 Qualification.

• Take into account the system-relevant conditions and requirements of the system manufacturer or system builder.

• Safety devices must not be dismantled, bypassed or rendered inoperative.

• Move the impeller of the fan by hand before installing it in order to check its free running.

• Provide contact protection, suction protection and safety distances in accordance with DIN EN ISO13857 and DIN

24167-1.

• Prevent foreign particles from being sucked in.

• Aswith a vibration transmission to the duct system is avoided, we recommend the use of the flexible connectors from

our accessories, see chapter Accessories.

Prerequisites

• Make sure that the fan and all its components are

undamaged.

• Make sure that the information on the type plate

(fan and motor) corresponds to the operating

conditions.

• Make sure that there is sufficient space for

mounting the fan.

• Mount the fans so that there is sufficient access for

troubleshooting, maintenance and repair work.

• Protect the unit from dust and moisture during

mounting.

Important

Overheating of the motor

• The installation distance must correspond to the picture below when the motor is aligned as specified. If the

motor protrudes from the enclosure, the distance between other motors or a wall must be  X A.Check that the

motor bearing is working correctly before installation.

• In addition to observing the maximum ambient temperature (see fan data sheet), make sure that the ventilation of

the motors is sufficient. Accumulated heat must be avoided at all costs.

Distance to a wall Distance to an air box

Important

There is a risk of damage to the bearings or fan parts.

• A duct bend must not be placed directly before or after the fan

• Ensure an even and constant air flow to the unit. A free exhaust air must be ensured.

8.1. Mounting positions

GBG and GBV

Important

There is a risk of damage to the fan if the condensation water cannot drain off.

• Make sure that the drain socket is always at the lowest point of the fan so that the condensation water can drain

off.
