J Series Airstage VRF – Fujitsu General
Fujitsu General has added to its “J-Series” Airstage VRF line with introduction of the smaller J-IIS series. The J-IIS avails variable refrigerant flow technology for smaller residential, multi-housing, and light commercial uses with equipment now available in three- and four-ton sizes.
The larger J-II VRF series — introduced earlier with three-, four- and five-ton sizes — helped to bridge the gap between its Halcyon multi-zone systems, and larger VRF technology. The J-IIS further enhances the offering with its compact size.
The J-IIS’ shorter height aims to provide easier installation in smaller spaces or when condensing units are stacked vertically. Both J-II and J-IIS equipment are single phase Airstage VRF products. Also, both are used in the same applications and with the same types of controls. The J-Series VRF systems offer up to 19.8 SEER and 11.4 HSPF.
Installers can connect up to eight indoor units to each condensing unit and choose from 11 indoor unit styles to create individually-zoned comfort for any size space. Indoor units range in size from 7 kBTU to 46 kBTU.
