Product catalog summary
Introduction
Ventilation is essential for maintaining indoor air quality by removing pollutants and replacing stale air with fresh air. Effective systems are crucial for energy efficiency and cost-effectiveness, particularly in residential and small commercial buildings.
Importance of Good Ventilation
Poor indoor air quality can lead to health issues such as asthma and allergies, and decreased performance. Studies from Harvard University and Sweden show that higher airflow rates can reduce absenteeism and improve health outcomes.
Pollution Sources
Indoor air pollution can come from outdoor sources like car exhaust and pollen, as well as indoor sources such as furniture and pets. Well-insulated homes can trap pollutants, worsening air quality.
Product Specifications
  • VR 300 TK/B: Designed for wall or ceiling installation, featuring a rotating heat exchanger, reversible design, and automatic operation modes. Includes centrifugal fans, filters, and a thermostat-operated reheater.
  • VR 250 EH/B: Suitable for smaller apartments, offering flexible installation and automatic operation modes. Includes a rotating heat exchanger, reheater battery, and filters, with easy control via a remote panel.
  • VR 400 EV/B and VR 700 EV: Designed for homes and small commercial spaces, featuring rotating heat exchangers, automatic operation modes, and maintenance-free motors. Includes a by-pass function for cooker hoods.
  • VR 400 E and VR 700 E: Similar to the EV/B models, offering automatic operation modes and suitable for installation in cold places due to their insulation.
Performance and Efficiency
All units are designed to maximize thermal efficiency and minimize energy consumption. They feature sound data specifications to ensure quiet operation and are equipped with control panels for easy operation and monitoring.
Conclusion
Systemair's heat recovery units improve indoor air quality while being energy-efficient and cost-effective, suitable for various residential and small commercial applications, offering flexibility in installation and operation.
Overview
The document provides technical specifications and operational details for ventilation units, specifically the VX 400 EV, VX 700 EV, and VX 250 TV/P models, designed for homes, offices, and smaller commercial buildings, offering features such as heat recovery, user-friendly controls, and flexible installation options.
Specifications
  • Voltage and Frequency: All units operate at 230/240 V and 50 Hz.
  • Power Consumption: VX 400 EV and VX 700 EV have motor powers of 2x138 W and 2x315 W respectively, with pre-heater and re-heater powers of 1670 W and 2670 W. VX 250 TV/P has motor power of 2x115 W and heating battery power of 1000 W.
  • Weight: VX 400 EV weighs 50 kg, VX 700 EV weighs 72 kg, and VX 250 TV/P weighs 30 kg.
  • Filters: Supply filters are EU7 for VX 400 EV and VX 700 EV, and EU5 for VX 250 TV/P. Extract filters are aluminum for all models.
Sound Levels
The document provides detailed sound power levels (LwA) across various octave bands for different operational settings (max, normal high, normal low) for both supply and extract air. These levels are measured in dB(A) and vary depending on the voltage setting and operational mode.
Thermal Efficiency
The units are designed to operate with an air ratio of 1:1 and air humidity of 30%, ensuring efficient heat recovery and air flow management.
Features
  • Double skin sheet metal casing with intermediate insulation for durability and noise reduction.
  • Centrifugal extract and supply fans with maintenance-free external rotor motors.
  • Control system with cross flow heat exchanger and thermostat-operated pre-and re-heater battery.
  • Automatic defrost function to maintain proper air flow.
  • Integrated or remote control panel with lamp indicators for settings and maintenance alerts.
  • Summer block accessory available for when heat recovery is not needed.
Installation and Maintenance
The units are designed for wall installation in areas like laundry rooms or closets. They offer easy maintenance with user-friendly control panels and built-in filter guards. Electrical connections are made via a 1 m cable and plug for earthed connection, with options for remote control panel signals and timer integration.
Applications
These ventilation units are suitable for residential and small commercial applications, providing efficient air management and heat recovery solutions.

Ventilation has a main task. It must take away all pollution produced in a building and take away the dirty air and replace it with clean air. The demand we make upon the ventilation is that it must work in the whole dwelling irrespective of wind and weather, without using more energy than necessary.Ventilation must be economical with energy I n recent years research shows that I we have less strength and perform poorer when we breath bad indoor air. We spent in average 70% - in cold- - of our time indoors. It goes with- out saying that the I 5 000 liters of indoor air we breathe throughout the...
