MVAC/MVACH - VAV Linear Diffusers

The Metalaire MVAC/MVACH series of VAV linear diffusers offer precise variable air volume control for optimal comfort and energy efficiency in HVAC systems. These diffusers utilize a unique wax-type actuator and an induction slot that samples room air temperature to modulate airflow. The MVAC provides cooling-only functionality, seamlessly transitioning from a fully open two-slot horizontal pattern to fully closed based on temperature differentials. The MVACH model expands upon this by incorporating automatic pattern changeover for enhanced heating performance.

A key feature of the MVAC/MVACH series is its ability to automatically adjust airflow based on room temperature. The precisely calibrated thermostatic actuator and room air sampling induction slot ensure accurate temperature control without the need for external power. This intelligent design allows for customized comfort by enabling temperature and volume adjustments directly from the face of the unit. Available in various lengths (24", 36", 48", and 60"), these diffusers can be tailored to suit a wide range of interior spaces. The MVAC is ideal for applications requiring cooling-only VAV control, while the MVACH excels in spaces needing both heating and cooling with optimized airflow patterns.

The MVAC/MVACH series is especially well-suited for perimeter applications in commercial buildings, offices, and other spaces where precise temperature control and adaptable airflow are crucial. During cooling seasons, the two-slot horizontal pattern ensures efficient air distribution, while the one-slot vertical pattern in heating mode provides a comfortable "warm air" wash. The combination of energy efficiency, precise control, and ease of installation makes the MVAC/MVACH series a compelling choice for modern HVAC projects.
