Frequently asked questions
The Air Handling Unit
It maintains temperature, humidity, differential pressure, and particle concentration levels. This type of installation must comply with applicable regulatory requirements. An efficient air handling unit is essential to meet air contamination control standards across various industries, including:
- Healthcare,
- Pharmaceutical industry,
- Biotechnology,
- Microelectronics,
- Precision industrial processes.
From a construction standpoint, the mechanical performance of units is evaluated according to the EN 1886 standard (casing deflection, leakage, thermal transmittance, and thermal bridging).
In public-access buildings (ERP environments), energy performance requirements must also be carefully assessed, taking into account the specific constraints of cleanrooms, particularly the prevention of cross-contamination between fresh and exhaust airflows.
On the intake side, G4 to F9 filters provide pre-filtration. On the supply air side, F7 to H14 filters achieve performance levels compatible with ISO 5 to ISO 8 classes, depending on the room requirements. The choice of filters is determined based on risk analysis, regulatory requirements, and the specific process involved. Our team of specialists can advise you in selecting the most suitable solution.
In a double-flow configuration, the AHU manages both air supply and extraction. This setup enables precise control of differential pressures and improved energy efficiency.
The choice depends on the project constraints, the required containment level, and the overall air handling strategy.
- The use of high-efficiency EC motors,
- Precise airflow control,
- Reduced-mode operation based on time schedules,
- Free cooling in the neutral zone,
- Absolute humidity control.
Together, these features deliver full regulatory compliance without compromising on energy efficiency.
- Targeted ISO class or health risk level,
- Required air change rate (volumes/hour),
- Differential pressures to maintain,
- Internal thermal loads,
- Architectural and operational constraints.
A precise aerodynamic and thermal study carried out beforehand guarantees the achievement of the expected performance levels and compliance with current standards.
Similarly to our VAHUs, the air handling units can be equipped with direct expansion coils. Cooling is achieved through heat transfer between the refrigeration circuit and the treated air. In compliance with current regulations, the refrigerant used has no harmful effect on the ozone layer.
Energy recovery systems can also be integrated:
Plate heat exchangers — thermal energy transfer occurs across the entire plate surface for maximum efficiency
Double glycol-water heat exchanger recovery systems — this solution ensures perfect separation between the two air circuits.
Smooth interior surfaces with no grooves or recesses provide long-term protection against micro-organism growth throughout the entire unit. Stainless steel base panels and condensate drip trays effectively prevent moisture retention, while the panel coating ensures flawless hygiene at all times.

High-Performance Air Management
Our AHUs handle fresh air supply, air recirculation, exhaust, and precise control of temperature, humidity, room pressure and filtration — all tailored to the specific requirements of each installation.
Unlike conventional AHUs, our units deliver significant savings in installation time, project cost and floor space — eliminating the need to dedicate technical rooms to air treatment equipment.
Our AHUs are fully suited for outdoor installation thanks to their robust construction, climate-adapted enclosures and compliance with current standards (thermal classifications T2 and TB2). A2i air handling units serve a wide range of critical applications including full surgical suites, healthcare facilities, pharmaceutical and cosmetic industries, microelectronics and high-precision manufacturing.
Like our VAHUs,these systems are designed as Plug & Play solutions. They do not require any additional configuration. Each unit integrates the electrical module, automation system, pipework, regulation components, PLC, display and sensors into a single ready-to-use package.
Available in multiple configurations to suit your specific needs, our AHUs are highly adaptable by design. Low noise levels — thanks to silent EC fans — make them particularly well suited for installation in close proximity to cleanroom environments. clean room.
