VAV Units Oman

Variable Air Volume Unit

A distinguished name in the acoustics ecosphere, Galloway Acoustics is the leading provider of pressure-independent and bypass VAV & CAV units in Oman. Powered by an entirely solar-powered, state-of-the-art manufacturing facility at Leminar Industries, the 325,000 square feet premises boasts world-class equipment that ensures each Galloway terminal unit is engineered to perfection as per stringent international industry standards.



Meticulously designed with the highest precision and latest manufacturing techniques, the VAV units include features such as an acoustically lined sheet metal box, a round inlet damper with a neoprene gasket, an airflow flow sensor, and a rectangular outlet, delivering optimal cool air to your space. 



For VAV applications, Galloway’s units precisely control the air volume in each room, adapting to the required cooling load. Whether it’s for supply or return air applications, the VAV or CAV terminals are the perfect choice for new projects or retrofitting existing ones. In CAV applications, the terminals maintain a constant airflow independently of the inlet static pressure. 


Galloway’s VAV units are rigorously tested and certified to meet the most stringent industry standards, including the AHRI 880 standard for unparalleled quality and performance. Additionally, our product line adheres to the AHRI 885 standard for NC noise levels that ensure a comfortable and quiet environment for your building occupants.


Renowned for their efficiency, Galloway’s products offer increased energy savings to building owners while reducing energy costs. Each Galloway terminal unit is equipped with the best-in-class, high-precision air flow sensors sourced from Europe with 98% accuracy. Our units are also tested with fibre-free insulation, making them ideal for critical applications in industries such as healthcare and food.


Backed by cutting-edge technology, superior craftsmanship, and a perennial commitment to quality, Galloway Acoustics is your go-to partner for all your VAV needs.
