Variable Air Volume- Aircoustics
Engineered For Silence — Precision Air Control for Maximum Comfort.
The Aircoustics Variable Air Volume (VAV) systems—engineered by Aircoustics FZE—deliver quiet, precise climate control for commercial and residential zones. Available in both pressure-dependent by-pass (ABV) and pressure-independent (APIV) models, these units feature low pressure drops, low sound levels, and energy-efficient operation designed to meet the rigorous demands of modern HVAC applications.
1. Model ABV (By-Pass Type)Zone Air Volume Control:
Provides pressure-dependent variable air volume to individual zones while by-passing unneeded air to the ceiling plenum for re-circulation.Constant CFM Supply: Allows zone variable air volumes while letting the supply fan deliver a constant CFM without costly fan controls.Flexible Control Options: Available with pneumatic, electric, or manual damper controls, including compatibility with reverse or direct-acting electric thermostats.Acoustic Performance: Built with thermally and acoustically insulated casings, low-leakage damper designs, and low pressure-drop characteristics.Easy Installation: Features open-end discharge with slip and drive connections, with optional multi-discharge adapters, hanger brackets, and internal foil-coated insulation (ideal for hospitals and laboratories).
2. Model APIV / CAVs (Pressure Independent Type)Precision Airflow Regulation:
Measures cross-sectional velocity and thermostat temperature signals via a microprocessor-based actuator to maintain strict minimum and maximum room airflow.Advanced ISO-Compliant Sensor: Equipped with an accurate velocity sensor designed in accordance with ISO 10780 to measure across the entire VAV inlet cross-section.DDC & Network Compatibility: Utilizes a modulating signal actuator (0-10V / 2-10V) compatible with Lon, MP-Bus, and BACnet systems.Robust Construction: Manufactured with 22 ga GI sheet casing and a leak-proof 24 ga blade, lined internally with 32 kg/m³ density acoustic insulation.Custom Options: Available with extended casing options up to 1.0 m for enhanced noise reduction, alongside integrated electric or water battery heaters.
Why Choose ABV By-Pass VAV?
The Aircoustics Model ABV by-pass unit provides pressure-dependent variable air volume to individual zones while allowing the supply fan to deliver a constant CFM.
The ABV by-pass unit is designed to regulate airflow to individual zones by bypassing unneeded air to the ceiling plenum for re-circulation. This provides a practical solution for buildings where zone airflow requirements vary while maintaining a constant supply fan airflow.
The ABV can be configured with reverse or direct-acting electric thermostats. The by-pass damper control ensures that only the required amount of air is delivered to each zone.

Frequently Asked Questions
The ABV model is a by-pass type unit that provides pressure-dependent VAV by diverting unneeded air to the ceiling plenum, keeping the supply fan operating at a constant CFM. The APIV model is a pressure-independent unit that utilizes velocity and temperature sensors with a microprocessor actuator to actively control minimum/maximum room airflow and vary fan RPM for energy conservation.
The ABV units can be ordered with pneumatic, electric, or manual damper controls, and are fully compatible with direct or reverse-acting electric zone thermostats.
Yes. The ABV model offers optional internal foil-coated insulation specifically designed for sensitive applications such as hospitals, laboratories, and schools. Similarly, the APIV series features high-density acoustic lining (32 kg/m³) and optional extended casings up to 1.0 m for ultra-low noise levels.
The APIV pressure-independent units use modulating signals (0-10V / 2-10V) and are compatible with Lon, MP-Bus, and BACnet building automation systems.
The ABV series supports air-flow capacities ranging from full zone shut-off up to 3,200 CFM (across sizes 02 to 32). The APIV series covers nominal airflows ($\text{Q}_{\text{nom}}$) up to 3,840 m³/h (Size 16).
