PreciseLine Air Handlers
PreciseLine® Air Handlers


No two buildings are created equal. Loads, fresh air, delivery requirements, and other design obstacles are clever problems that call for clever solutions. For a definitive solution to your space’s air handling needs, use Daikin PreciseLine Air Handlers, available in both vertical and horizontal configurations, to condition air at precise levels up to 10,000 cfm. PreciseLine’s compact footprint gives system designers and contractors unmatched design capability when faced with tight space restrictions. It differentiates itself by utilizing a series of smaller units to efficiently deliver fresh, conditioned air to dedicated spaces within a building ⁠— all at a very attractive price point.

thermally insulated Panels

All units utilize a galvanized double wall, 1-inch foam injected, thermally isolated panel to raise the cabinet’s thermal resistance to R-6.5. This thermal resistance is more effective at keeping air cold when in cooling mode and hot when in heating mode. It also provides a cleanable surface and increases panel rigidity for longer unit life.

PreciseLine controller


Intuitive, factory-integrated controls provide for standalone operation or BAS integration, effectively reducing installation time, costs and complexity, while also ensuring the most efficient and reliable operation from your air handler.


factory-installed valve packages

Available for both two-pipe and four-pipe systems (006-020), all packages are leak tested and assembled inside the cabinet. Water connections terminate outside the cabinet for quick field hookup and all valve piping is easily accessible through a single panel for easy service.
