Ventilation Units - Vari-Airbox

Product catalog summary

General Description
A comprehensive range of ventilation units with variable air-flow volume, featuring centrifugal fans with external rotor motors. These units are designed for modern installations, offering silent operation, durability, versatility, and ease of installation. Airflow control is integrated with both manual and centralized digital device regulation options.

Characteristics
The units feature centrifugal double inlet fans with external rotor motors protected by thermal contact. Speed control is achieved through an electronic selector and a 5-stage converter integrated within the box. The radial impellers are high-performance, balanced both statically and dynamically, ensuring silent and vibration-free operation. The casing is made from extrusion aluminum profiles with high-impact resistant plastic corners. Panels are interchangeable, and a variety of accessories are available to facilitate installation.

Construction and Materials
The standard series includes galvanized steel panels with 25 mm fiberglass insulation for sound absorption. Optional sandwich panels and acoustic panels with 50 mm insulation are available upon request. The use of metallic metric thread screws allows for quick and professional servicing.

Technical Specifications
Various models are available with different power, speed, and temperature specifications. All models operate at 230V and 50Hz frequency, with motor protection rated at IP 44 or IP 54 depending on the model. The units are designed to handle maximum temperatures ranging from 50ºC to 70ºC.

Operating Control and Regulation
The units come with a 5-speed standard controller that provides interference-free speed regulation. Connections are external, using RJ45 connectors for easy installation. The controller supports digital communication, allowing for long-distance operation and control of up to 12 units in series. Additional features include external ON/OFF control, memory function, and manual/automatic operation options. An electrical heating controller is available, allowing for 3-stage heating regulation.

Interface and Centralized Control
An interface box is available for connecting the digital controller to centralized digital management systems like DDC, PLC, or BMS, enabling comprehensive control of all equipment functions.

Operating control and regulation 5 speed Standard controller. This controller provides a 5-stage speed regulation by voltage modulation totally interference free, motor noises and vibrations free. All connections, both the input and the control, are placed outside the equipment. For a simple connection free of errors, between the controller and the equipment there is used a telephonic type cable with connectors RJ45, what reduces sensibly the installation time. The digital communication with the controller increases the protection against interferences and allows long distances (till 300m) between...
