DESTINATION
The in-line mixed flow fans with channels' diameters ranging from 100 to 150 mm are
designed for installation in the ventilating systems that require high pressure, powerful
air flow.
The pumped air should not contain dust and other solid admixtures, as well as sticky
substances and fibrous materials, the temperature of the transferred air must not exceed
+45°C. Fans are installed horizontally vertically and can be used both for exhaust and for
blowing ventilation. The fans are manufactured as two-speed ones and are designed for
long-term operation without switching off mains.
By the type of protection against electrical shock the fans belong to Class II.
The degree of protection against access to the hazardous parts and water intrusions
is IPX4.
Design of the fans is being constantly perfected, so some models could differ from other ones ‘
described in this certificate
THE BASIC TECHNICAL DATA
The fans' designations, their parameters, connective and mounting dimensions are
provided in fig 2-3. Fans are intended for connection to 230V AC, 50 Hz. An external 3A
fuse is required for each fan unit. It is permitted to use the fan under ambient air temperature
from +5oC to +40oC

The fans of the AV-series have two working speeds, that is shown in the tab.1with record
through a fraction: in the numerator the minimum velocity, in the denominator the maximal
velocity.

MAINTENANCE
Maintenance of the fan is carried out only after switching it off the mains. Maintenance
consists of periodical cleaning of the surfaces from dust and dirt, when the fan is switched
off the mains. To remove the dust, use a soft dry brush or compressed air. Blades of the
impeller require careful cleaning every 6 months. To do this, dismantle the fan from the
channel, take off the clamps 6 and remove the body 1. Using the water solution and
detergent, wash the blades of the turbine, avoiding fluid intrusion onto the electric motor.
STORAGE RULES
Store the fan in the manufacturer's packaging in an aerated premise at the temperature
from +5°C to + 40°C and relative humidity of the air of not more than 80 % (at T = 25°C).

SAFETY REQUIREMENTS
By the type of protection against electrical shock the fans belong to the Class II. The
degree of protection against access to the hazardous parts and water penetration is
IPX4. All actions, related to connection of fans to the mains and adjustment of
the timer turn-off delay time are to be carried only if the mains voltage is
switched off.
RECOMMENDATIONS
For horizontal installation of the fan, place an air duct with the length of not less than 1m
on the suction side; for vertical installation of the fan, it is necessary to place a valve/ grille
at the suction duct end. Connection of the fans is carried out by a specialist electrician
who has a special access to the operations performed. Operation of the fans outside the
working temperature range is forbidden, as well as exploitation in premises with
aggressive impurities in the air. Before connection of the fan to the mains it is necessary
to ensure that there are no visible damages of impeller, body, lattice, as well as
extraneous objects in the blowing part of the body, which can damage runner vanes.
Maintenance and repair of the fan should be carried out only after its switching off the
mains.
ATTENTION!
Operation of the fan with extraneous subjects in the blowing part of the body, which can
damage or jam the runner vanes, is forbidden. Precautions must be taken to avoid the
black-flow of gases into the room from the open flue of gas or other fuel-burnin
appliances.

INSTALLATION AND CONNECTION OF THE FAN TO THE MAINS
The fan (fig.1) consists of the body 1 with fixed electric motor and impeller 4. Terminal box
cover 3, pipes 5 (pipe diameter corresponds to the diameter of the air duct); quick-
detachable clamps 6.
Air moving direction of the air should coincide with the direction of the arrow on the fan
body.
For the installation of the fan it is necessary to carry out following operations: 1) Remove
two clamps 6 and to take out the body 1. 2) Drill holes for dowels, according to the
coupling sizes and fix the pipes by means of 4 screws. 3) Insert the body 1 and fix it with
clamps 6. 4) Connect air ducts of the relevant diameter.
Connection of the fan to the single-phase circuit should be carried out through the switch
built-in into the stationary wiring. The gap between contacts of switch at all poles should
be not less than 3 mm.
Connection layouts of the fan to the stationary wiring are shown on figs. (2-3). In case of
one-speed operation at one speed, it is necessary to connect the wire L of the mains to
one of the terminals, corresponding to the s elected rotation speed:
LHmaximum speed
LLminimum speed
Speed of the fan is switched using external switch S1. Fan with timer T (fig 3) ensures
automatic turning off the fan after certain time from 2 to 30 minutes, set up by the timer.
Turn-off delay time is adjusted, using the handle of potentiometer, rotating it clockwise to
increase the delay time and anticlockwise to decrease it.
To connect the fan to the mains, it is necessary to:
-remove the cover from terminal box,
-extend electric wires through the gasket ring, located on the terminal box,
-remove insulation from the ends of wires by 5-6mm, insert them into appropriate
terminals until insulation is rested against the metal part of the terminals, and fix them
with screws,
-place back the terminal box cover.
ATTENTION!
Launching the fan, equipped with timer, occurs within approximately 5 s after turning on
external switch S2.
