2. Application
WPA-P-N portable radial fans have been designed for air-supply ventilation or extraction
ventilation of rooms and workplaces. They can be applied for general ventilation and for local
exhausts. Additionally, WPA-P-N fans can be used or drying the humid rooms by forcing the
multiple air exchanges.
Do not use the fan for conveying the aggressive gases or substances creating explosive
atmospheres with the air.
In general, the fan is designed for transporting the air, of dustiness not exceeding 0,3 g/m³,
without viscous impurities, aggressive contamination or compounds creating hazard of explosion.

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 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 impeller 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
buildings. In case of outdoor application (especially for a longer time of operation) it is
important to protect the device against atmospheric factors.
The appliance do not require special preparation 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 according to the arrow on the housing, if this is the opposite, change the phase
connection sequence).
own. It is important to select the right type and section of the supply cable, and choose
the appropriate short-circuit- and overload protection, according to the local conditions.
Approaching with loose clothes or putting the hand near the open inlet
of the running fan can cause hazard of accident. Do not look into the working fan as
this could cause the face injury of User.
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.

Portable radial fans WPA-P-N 27.09.2016
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 supply a hose
(into the ventilated room), whereby the hose ought to be connected to the suction ferrule or
to the outlet ferrule 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. In this application, the suction nozzle
can be equipped with a suction stand with a directing spout nozzle (see Photo No.1b).
Construction of the device guarantees a reliable function without continuous technical
supervision after the start-up.
In case when any defective function of the unit occurs (e.g. improper noises or the faulty
outlook of the device) follow steps as in Section 8.

9. Maintenance
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 device 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 maintenance activities should be executed exclusively
by an authorised person and after disconnection from the power system.
(the exemption from this are activities carried out on the running fan, under strict
observing the Occupational and Health Safety rules –e.g. vibration measure-ment).
Before 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
originating from the conveyed medium.
During the maintenance activities follow strictly the rules of Occupational Health and Safety,
in order not to cause hazard to workers.

12
Portable radial fans WPA-P-N 27.09.2016
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 technical revisions and repairs have to be executed necessarily
after disconnection from the power system.
11. Transport and Storage
The fans shall be transported on pallets and protected with foil.
During the loading and transport the package should not be thrown neither knocked down
or charged with a load on the top. Do not place one package on top of another 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 warranty does not comprise:
●
mechanical damage and dysfunctions caused by User,
●
device failures caused during use which was in contradiction with the purpose of
operational use and the present “Use and Maintenance Manual”,
●
damages being effected during improper transport, storage or incorrect maintenance.
Infringement of the Section 3 “Reservations of producer” of the User’s Manual and
especially modifications undertaken by User on one’s own shall cause the loss of
warranty validity.
