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

Notes.

The diameter of the air duct should match with the diameter of fan delivery pipe

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.
