The air supply unit Vents MPA 1800 E3 in compact dimensions 800x649x480 mm is used to supply fresh air in the supply ventilation system. The ventilation unit is delivered ready for operation; the air in the unit is filtered and, if necessary, heated by a built-in electric heater. The ventilation unit can provide a maximum capacity of 2000 m3/h, a heater with a power consumption of 18 kW is used for heating.
The unit is intended for installation in a closed room with positive temperature. This model comes with a built-in automatic control system for operating modes.
House
The body of the Vents MPA 1800 E3 unit is made of aluminum-zinc steel, which is more durable compared to conventional galvanized steel. To prevent heat loss and reduce noise levels, the unit body is insulated with 25 mm thick mineral wool. To allow for service maintenance, one of the walls of the unit can be opened.
Filter
To prevent pollutants in the outside air from entering the ventilation system, the unit is equipped with a filter with a replaceable cassette. Filtration class G4.
Heater
Heating of the supply air during the cold season is carried out using a built-in electric heater. To increase the area of contact of air with the heater, additional fins are provided on the heater.
Fan
The installation uses a centrifugal fan with forward-curved blades. To protect the fan motor, thermal protection with automatic restart is provided. Electric motors use ball bearings. Sealed rolling bearings require virtually no maintenance. Their service life is up to 40,000 hours.
Installation control
The installation is equipped with a built-in automation system based on a controller and is ready for operation.
Functions of the built-in automation system for the air supply unit< /h3> - turning the unit on and off
- protecting the air heater from overheating
- alarm about the need to clean filters or replace them
- possibility of adjusting the performance of the supply air installations. Adjustment is stepwise - 3 speeds are possible.
- unit operation by timer
Installation
The air handling unit can be placed in utility rooms (balcony, loggia, dressing room ) or in the main ones under the ceiling or in a niche.
The installation can be mounted on the floor, to the ceiling or on the wall using brackets. During installation, it must be taken into account that access to the installation is required for servicing, i.e. it is necessary to provide an inspection hatch or another method.
Using the installation using the example of office ventilation
An MPA air supply unit is installed in the ceiling space. For air intake and exhaust, holes are made in the outer walls. Fresh air passes through the external grille, enters the unit, where it is filtered, if necessary, heated to the required temperature and from the unit is supplied through a network of air ducts through grilles to the offices. Air is removed using an exhaust fan through a network of air ducts. Thus, with the help of an air supply unit and an exhaust fan, the required calculated air exchange is carried out to ensure comfortable ventilation in office premises.
