- fresh air from the central ventilation unit - air inlet from the box into the ventilated space
- exhaust air from ventilated space - waste air from the box to the central vent. unit
Combined inlet and outlet ventilation VBM-V box is designed to be used in the DCV (demand controlled ventilation) air-
conditioning systems with the possibility of regulation of the inlet and outlet air volume on the basis of actual need of ventilation in
a ventilated space of industrial or residential buildings.
This VBM-V box may be used for flats, hotel apartments, offices, etc. In the box, there are integrated air flow controls, which are
equipped with noise attenuators on the inlet and outlet side. Box is designed to be mounted into the wall or ceiling. On the box
shell, there are integrated rails mounted. The entire box is electrically connected and pre-set in the factory. This ventilation box
may be placed into a furniture case of 600mm size. Each ventilation box may be controlled by a separate remote control. In the
box, there is a power supply and control unit installed for the air flow control with a flexible connection with euro type plug designed
for the sockets of general electric circuits, 1x230V/50Hz.
External remote control for a concealed assembly is led through bushing in the outer box shell into the control unit.
Boxes are designed for the environment protected against climate effects within the air temperatures range from -15°C to +45°C
and within the relative air humidity range max. up to 95% (condensation on the box top or in the internal box components has to
be avoided). Air driven by exhaust has to be free of any abrasive, chemical and sticky additives.
Unless states otherwise, all the sizes are in mm and weights in kg.
Box construction differs according to the order specification.
Ventilation box construction differs according to the side, air inlet part on the neck for SUP fresh ventilation air inlet into the box -
LEFT ("L" code) or RIGHT ("P" code). Another element making difference is the flow rate size of the unit and control unit type.

Box is designed for its installation into the wall or ceiling. On its shell, there are supporting rails mounted. Box is fixed to the wall by
using 4 oval openings in the bearing rails. It is necessary to use appropriate type of fixing screws (recommended M8 screw size) and
anchors with load corresponding to the box weight.
Ceiling installation should be always performed by a removable lid in a downward direction, i.e. to the floor. Vertical wall fixing is possible
in the direction of air inlet flow (SUP) from the bottom to the top or in the direction of air inlet flow (SUP) for the top to the bottom.

Shell of the VBM-V ventilation box is made of steel zinc plates. Box is equipped by flanged with edge rubber sealing. Flow rate
controllers’ shells and valve dampers are made of zinc plates. Pins of the dampers are made of galvanized steel. Controller
damper is equipped by a silicone sealing. Bearing pipe of the noise attenuator is made of a perforated aluminium plate and
insulation material of the attenuator is made of rock wool and shell from a polyester foil.
After the final assembly is complete, an output quality control of the ventilation box will be executed, where the final conformity is
tested with the requirements in the order.
