Concealed Duct FCU with Flexible Static Pressure for Commercial HVAC
241mm Slim Duct FCU with Left/Right Piping Dual Air Inlet
Product Overview
The Midea Medium Static Pressure Duct Fan Coil Unit provides concealed, ducted climate control for commercial spaces where aesthetics require hidden equipment. With a slim 241mm profile (AC) / 261mm (DC), these units install in standard ceiling cavities and distribute conditioned air through ductwork to single or multiple zones.
Available in 3-row and 4-row coil configurations for 2-pipe and 4-pipe systems respectively, the series includes standard and large-temperature-difference variants. Left and right piping connections can be changed on-site (AC MKT3-CL & MKS3-CL series), offering maximum installation flexibility. The air inlet can be positioned on the rear or underside of the unit, with an optional extended water pan for ceiling condensation protection.
