Airstage VRF


Airstage VRF

Fujitsu General America’s Airstage VRF system wall-mount, floor-mount, compact cassette, and slim duct evaporators are now available in 4,000-Btu capacities.

The new indoor units are compatible with Fujitsu’s Airstage VRF V-Series (three-phase) and J-Series (single-phase) heating and cooling systems. The smaller capacity offered by these units creates more flexibility in the growing residential VRF market and in commercial applications with tighter building envelopes or smaller zones.

Although inverter technology allows for VRF systems to adapt to the needs of the space, smaller zones in new construction may only need 1,500-2,000 Btu. If a designer is given this type load and is forced to use 7,000- to 9,000-Btu indoor units, the comfort of the space will be compromised. In addition, the overall size of the outdoor units will need to be larger to accommodate the larger indoor products.

“With the expansion of green building practices, Fujitsu is introducing 4,000-Btu indoor units to provide just the right amount of load, eliminating oversizing and creating an energy-efficient solution ideal for high-performance buildings”, said Kal Osman, director of product management, Fujitsu. “Because these indoor models are compatible with the full Airstage line of VRF products, they are the perfect solution for low-load applications in both residential and commercial sectors.”

With four indoor unit styles to choose from, the new units are applicable for nearly any indoor space, requiring minimal heating and cooling loads, according to the company. For more information, visit
