2. Application
WPA-P-N fans have been designed both, for air-supply ventilation and extraction ventilation of
rooms and workplaces. They can be applied for general ventilation and for local exhausts. Addi-
tionally, WPA-P-N fans can be used or drying the humid rooms by forcing the multiple air exchan-
ges.
Do not use the fan for conveying the aggressive gases or substances creating explosive atmos-
pheres with the air. In general, the fan is designed for transporting the air, of dustiness not ex-
ceeding 0,3 g/m³, without viscous impurities, aggressive contamination or compounds creating
hazard of explosion.
3. Reservations of Producer
A.
Manufacturer accepts no liability for any consequences following from the operational use
that is in contradiction to the purpose of application.
B.
It is unacceptable to install on the device structure any additional elements not belonging to
its normal construction or accessory set.
C.
Any structural changes or modification of the device, carried out by User on one’s own are
not permitted.
D.
Protect the housing from mechanical damage.
E.
The fan cannot be used for conveying the air contaminated with a mixture of flamma-
ble substances in form of gas, vapour, mist and dust that in connection with the air
create the explosive atmosphere.
F.
Do not use the fan for conveying the air containing viscous impurities that could accumulate
on the device surface, especially on the impeller.
G.
Neither use it for forwarding the air with aggressive pollutants which will destructively effect
the device structure.
H.
During operation, the maximum impeller rotations should not exceed the nominal rotations.
I.
Manufacturer is not responsible for wounds, injuries, body laceration experienced by User or
personnel during the improper operational use.

5. Structure and Function
The fan consists of a steel spiral housing and a motor and a radial impeller which is directly
mounted on the motor shaft (direct drive). The structure rests on a base frame structure. The
inlet and outlet are adapted for connection of the flexible hoses, which are clamped with hose
clamps. For safety reasons, the inlet and outlet are equipped with a protective grill. The impel-
ler with profiled radial blades provides low acoustic pressure of the fan.
As standard, the fan is equipped with a motor protective switch.Each fan is energized through
a five metre long power supply cable with a plug.
6. Assembly and Start-up
The portable WPA-P-N fans can work in closed rooms (indoor application) and outside the buil-
dings. In case of outdoor application (especially for a longer time of operation) it is important
to protect the device against atmospheric factors.

7
04.06.2019 portable radial fans WPA-P-N
The appliance does not require special preparatory activities before start-up.Depending on the
purpose of application, it is important to provide suitable hoses (see Section 7 of the present
Use and Maintenance Manual) .
The device is energised through a motor protective switch (or by a motor starter). Appropriate
Connection Diagrams are shown in Fig. No.3.
Prior to the start-up, check the connection between the motor and the PE protective cable, and
the correctness of the electrical connections (the impeller rotation sense ought to be accor-
ding to the arrow on the housing, if this is the opposite, change the phase connection
sequence).
Approaching with loose clothes or putting the hand near the open inlet
of the running fan can cause hazard of accident and disability. Absolutely, do not look
into the working fan as this could cause the face injury of the operator.
In case of any activities carried out on the fan, it is important to disconnect the device
from the power supply system.
The windings ought to be connected according to the Connection Diagram on the terminal box cover
Fig. No.3 –Connection Diagram of the fans type WPA-P-N

portable radial fans WPA-P-N04.06.2019
7. Operational Use
In case when the portable fan is applied for local exhaust (technological extraction), connect a
hose (of adequate diameter) to the suction ferrule. Additionally, the hose must be tipped with a
suitable suction nozzle. Example application with a magnetic suction hood is illustrated in the
Photo No.1a below.
Photo 1a
Photo 1b
Portable fan working with a magnetic
hood during the welding
Portable fan used for drying a humid wall
Photo 1 –Examples of application along with the hoods
When the portable fan is applied for general ventilation, it is important to introduce a hose (into
the ventilated room), whereby the hose ought to be connected to the suction ferrule or to the out-
let fitting piece of the fan.
In case of application for drying the humid walls of a room, simply put the fan into the room and
direct the air discharge onto the humid wall. The discharge hose must be conducted outside the
room.
As another option, the portable fan can be placed outside the building (the drying air has to be
forced through an air supply hose into the humid room). Here, it is important to protect the fan
from atmospheric factors by a hood / cover. In this application, the suction nozzle can be equip-
ped with a suction stand with a directing spout nozzle (see Photo No.1b).
In case when any defective function of the device occurs (e.g. improper noises or the faulty out-
look of the device) follow steps as in Section 8.

9. Maintenance and Control
In the aspect of operational use, the fan construction guarantees its efficient function without
continuous everyday technical supervision. Nevertheless, to obtain proper function of the de-
vice and to follow the safety rules, manufacturer suggests executing technical revisions
on regular basis. During the inspection check the function of the fan and the technical state
of its elements.
Any activities related to connection to the power supply system ought
to be executed by an authorized person with electrical qualifications.
The appliance should be disconnected from the power mains (exemption from this are
activities carried out on the running fan, under strict observing the Occupational and
Health Safety rules –e.g. vibration measurement).
Prior to the maintenance on the fan, necessarily disconnect it from the power supply system
and wait until the impeller stops rotating.
Within the scope of inspection execute following activities:
●
check and tighten the mechanical and electrical connections,
●
examine the mountings of the motor and the fan, important is that the clearance between
the inlet and the impeller is even within the whole circumference.
●
remove the impurities accumulated inside the fan, eventually clean it from pollutants origin-
ating from the conveyed medium.
10. Occupational Health and Safety
Start up and the operational use is only admissible exclusively after getting acquainted
with the contents of the present Use and Maintenance Manual.
Connect the fan to the electrical wiring system, strictly according to the enclosed Connection
Diagram and the guidelines shown in Section 6 of the present Use and Maintenance Manual.
This ought to be carried out exclusively by a qualified person, and in accordance with
the valid regulations.
During the operational use, check the connection between the fan and the PE protective cable.
Any activities connected with technical revisions and repair have to be
executed necessarily after the device is disconnected from the power supply system.
11. Transport and Storage
The fans shall be transported on pallets and protected with foil. During the loading and tran-
sport the package should not be thrown neither knocked down (overturned) or charged with a
load on the top.
Do not place one package on top of another (no stacking) and,during the transport protect the
device from atmospheric factors and from damage, indents. The device ought to be stored in
dry and well ventilated rooms.
12. Terms of warranty
The period of warranty for the purchased device is indicated in the “Card of Warranty”. The war-
ranty does not comprise:
●
mechanical damage and dysfunctions caused by User,
●
device failures caused during use which was in contradiction with the purpose of the opera-
tional use and the present Use and Maintenance Manual,
●
damages / malfunctions being caused during improper transport, storage or incorrect main-
tenance,
