Fujitsu General America introduces the AIRSTAGE J-7S line of VRF heat pumps. Utilizing the low GWP (Low Warming Potential) R-32 refrigerant, the new models offer greater installation flexibility, improved efficiency, and more compact cabinets than Fujitsu’s previous single-phase offerings.
The J-7S line includes two-, three- and four-ton models designed for commercial and light commercial applications. Certified energy efficiency ratings reach up to 15.7 for EER2, 22.2 for SEER2, 11.3 for HSPF2, and 4.64 for COP2.
Optimized for a wide range of climates, AIRSTAGE J-7S systems operate reliably in outdoor temperatures from -15°F to 70°F in heating mode, and 23°F to 122°F in cooling mode. A built-in base pan heater ensures reliable winter performance. Most models are ENERGY STAR® and ENERGY STAR® Cold Climate certified.
Installation flexibility was a central design goal. The new heat pumps feature a 16 percent smaller footprint than earlier models, reducing mechanical space constraints. A single outdoor unit supports up to 12 indoor units for versatile zoning.
To support an extensive variety of system designs, the four-ton unit allows a maximum total equivalent pipe length of 393 feet. A 50 percent to 130 percent system connection ratio on three- and four-ton models enhances load matching for varying project needs.
Factory refrigerant charge is limited to 5.95 pounds across all models, simplifying regulatory compliance. Despite an impressive outdoor fan static pressure capability of 0.12” W.C., sound levels remain as low as 52 dB(A).
