PACi Standard and Elite: indoor units
4-Way 60x60 Cassette
Lighter and slimmer, easier installation
Lightweight and very slim which makes installation possible even in narrow ceilings.
A drain height of approx. 850 mm from the ceiling surface
The drain height can be increased by approx. 350 mm over the conventional value by using a high-lift drain pump, and long horizontal piping is possible.
Significant reduction of power consumption by using highly developed DC fan motors with variable speed, special heat exchangers, etc.
Convenient cleaning. The flap can be removed easily for washing.

Further comfort improvement
The wide air discharge opening expands the air flow to the left and the right.
The unpleasant feeling caused when the air flow directly hits the human body is prevented by the “Draft prevention position”, which changes the swing width, so that the degree of comfort is increased.

High Static Pressure Hide Away (PF Type)
The static pressure outside the unit can be increased up to 150 Pa.
Type: 60 kW Standard: 70 Pa / 71 kW Standard: 70 Pa / 100 kW Standard: 100 Pa / 125 kW Standard: 100 Pa / 140 kW Standard: 100 Pa Type: 60 kW Max. available setting: 150 Pa / 71 kW Max. available setting: 150 Pa / 100 kW Max. available setting: 150 Pa / 125 kW Max. available setting: 150 Pa / 140 kW Max. available setting: 150 Pa
More powerful drain pump
Using a high-lift drain pump, drain piping can be elevated up to 785 mm from the base of the unit.
Air inlet
The unit features air inlet on one side, air outlet on the other side. The air inlet filter can be pulled out from the side of the unit and can be folded. Easy access if through the maintenance opening.
When air inlet duct (field supplied) is connected on suction side, remove the filter, frame and insulation materials on both sides of the unit. Connect the duct on the suction side of the unit by using prepared holes on the unit.
Air outlet site
A rectangular duct flange for the air outlet is fitted as standard. Round outlet flange kits are available as an optional accessory kit.
