Daikin Outdoor-air processing unit (FXMQ-MF Series) introduces outdoor air and pre-condition the outside air via a fixed discharge temperature control to suit your needs, thereby reducing the indoor air conditioning load. VRV indoor units for air conditioning and an outdoor-air processing unit can be connected to the same refrigerant line. This results in enhanced design flexibility.

OAPU – How It Works (with VRV Indoors)
The fresh air is introduced to OAPU and treated before going into the office, also will then go into the VRV Indoor units.

PM2.5 Filtration Unit (Option)
Removes PM2.5 particulate matter present in the outdoor air, as well as sulfur oxides and nitrogen oxides, providing clean fresh air to the indoor ambient.
• PM2.5 filter: Removes 99% or more of 2.5 μm particulate matter.
• Activated Carbon filter: Removes sulfur oxides and nitrogen oxides




Electrostatic Dust Collection Filter: More Efficient and Longer Lasting Effect
The PM2.5 filter layer contains a large amount of static electricity to capture particulate matter effectively, including those smaller than the grid mesh.
The filter is difficult to be blocked by particles and has good ventilation and long life span.
