Gree duct type R410a is the epitomy of utility in professional requirements, such as office and commercial areas. They are durable big capacity units combined by versatile fan systems, allowing both high pressure output, together with low noise, air filtration, and flexible control.

Static pressure can reach 150 Pa, and filters include standard dust filters, as well as NM photocatalyst and silver Ion. Moreover, a built in water pump and 2 remote controllers provide for a flexible installation. The wired controller is equipped with IR receiver, room sensor, for fresh air installations, and outdoor temperature for convenience to use.

Finally the unit is backed by a durable R410a scroll compressor allowing a reliable life span, together with big capacity and low noise operation.
