AirFixture air handling units deliver engineered air distribution for commercial spaces, combining filtration, heating, cooling, and humidity control in a single modular package. These units integrate with building management systems to balance indoor air quality, thermal comfort, and energy efficiency across zones.
This quick introduction outlines core functionalities, typical configurations, and decision points for facility managers evaluating AirFixture AHUs for new builds or retrofits.
| Model | Air Volume (m³/h) | Heating Range (kW) | Cooling Range (kW) | Control Type |

| AF-500 | 500 | 12 | 15 | Modbus |
| AF-1000 | 1000 | 24 | 30 | BACnet |
| AF-1500 | 1500 | 35 | 45 | Modbus |
Air Handling Unit Core Components
An AirFixture air handling unit organizes airflow through fans, filters, coils, and dampers housed in a insulated metal shell. Each path is designed to minimize pressure drop while maintaining thermal performance and sound attenuation.
Unit Selection and Application Scenarios
Selecting the right AirFixture AHU depends on space load, airflow pattern, and control granularity. Units serve offices, schools, light industrial zones, and healthcare settings where consistent air change rates and precise temperature bands are required.
Integration with HVAC Controls
AirFixture units interface directly with building automation systems via BACnet or Modbus, enabling setpoint adjustments, damper sequencing, and demand-controlled ventilation. This integration supports part-load efficiency and real-time fault detection.
Energy Performance and Air Quality Features
High-efficiency filters, rotary heat exchangers, and variable-speed fans help AirFixture AHUs reduce energy use while sustaining target IAQ. Demand-controlled ventilation adjusts outside air intake based on occupancy sensors to limit over-ventilation.
Installation and Commissioning Steps
Proper site assembly, duct coordination, and control wiring streamline AirFixture AHU commissioning. Factory-tested modules reduce on-site adjustments and shorten project timelines.
Operational Best Practices and Maintenance
- Schedule quarterly filter checks and replacement to sustain designed airflow and efficiency.
- Verify damper positions and actuator calibration during seasonal commissioning.
- Monitor coil performance and drainage paths to prevent moisture carryover.
- Use trend logs from the BMS to track fan energy and temperature setpoint adherence.
FAQ
Reader questions
What typical air volume ranges do AirFixture units support?
AirFixture AHUs are available from 250 m³/h to 1500 m³/h, allowing coverage from small conference rooms to large open-plan zones.
How do AirFixture units maintain humidity control during cooling?
Reheat coils and integrated dehumidification paths prevent overcooling and control relative humidity within specified comfort bands.</
Can AirFixture AHUs integrate with existing BMS platforms?
Yes, units natively support BACnet and Modbus, enabling seamless integration with most modern building management systems.
What noise levels should I expect from an AirFixture AHU?
Factory-mounted silencers and insulated liners keep sound pressure levels low, typically meeting workplace acoustic requirements for occupied spaces.
