The fan casing is made of an aluminium frame fastened with aluminium corners and removable heat- and sound-insulated double-layer
panels made of aluzinc.
Thanks to its corrosion-resistant aluzinc casing and heat-insulation material, the fan is suitable for outdoor installation.
The VSK fan is equipped with an asynchronous motor with an external rotor and a centrifugal impeller with backward curved blades.
The fan has a special design that allows you to change the position of the side panels for air supply in directions at an angle of 90°.

When connecting the fan to the air duct system, it is recommended to use the accessories specified in the User’s manual.
Connecting spigots, which also serve as vibration damping inserts, can be of square or round cross-section.
Spigots of round cross-section are equipped with rubber seals.
Connecting spigots are not included in the delivery set, they are ordered separately.
DESIGN AND OPERATING PRINCIPLE

VSK

Before installing the fan, make sure that there is no visible damage to the impeller and check the integrity of the insulation of the power
supply wires.
The impeller must rotate freely without touching the flange and casing.
The fan must be installed in an air duct of similar diameter.
The fan must be mounted in such a way that the direction of the air flow arrow on the fan casing coincides with the direction of air in the
system. The fans are installed between the air ducts.
The connection to the air ducts is carried out using an appropriately sized flexible adapter.
In case of mounting the fan on flexible joints, attach the fan to a structural unit by means of brackets.
The fan can be mounted in any position according to the direction of air flow (indicated by the arrow on the fan casing).
To attain the best performance of the fan and to minimize turbulence-induced air pressure losses while mounting, connect the straight
air duct section to the fan spigots on both sides of the fan. The minimum straight air duct length is equal to 1 air duct diameter on the
intake side and 3 air duct diameters on the exhaust side.
No filters or other devices must be installed in these sections.
The fan is not a ready to use unit and requires connection to the air ducts.
Install the fan securely while ensuring free access for maintenance operations, the required distance to the walls of the room is at
least 1 m.
The VSK fan is equipped with a drain fitting for connection to the drainage system.
Fan installation sequence:
• Before installation, route the wires and cables necessary to connect the fan to the mains.
• Make sure that the motor is not energized.
• Fasten the MK VSK brackets in accordance with the supporting plane (structure).
• Fix the fan to the MK VSK mounting brackets using suitable fasteners (e.g. dowels).
• Connect the air ducts to the fan.
Mounting of MK VSK brackets The fan can be mounted on a
horizontal plane
If installed outdoors, the
fan can be equipped with a
protective hood - VPR VSK
Installation of the drain fitting
The MK VSK brackets and the VPR VSK protective hood are not included in the delivery set and must be ordered separately.
WHILE INSTALLING THE UNIT ENSURE CONVENIENT ACCESS FOR SUBSEQUENT
MAINTENANCE AND REPAIR.
BEFORE MOUNTING MAKE SURE THE CASING DOES NOT CONTAIN ANY FOREIGN
OBJECTS E.G. FOIL, PAPER.
