Corridor and perimeter packages are won on speed: the faster each unit goes in, the more floors your crew closes out per week. The Midea One-way Cassette Fan Coil Unit is built for exactly this kind of work. A 153mm chassis slides into the narrow ceiling voids above corridors, lobbies and room entryways where standard cassettes simply do not fit, and the single-direction discharge throws conditioned air along the hallway instead of fighting the walls. With cooling capacities from 2.65 to 5.20 kW across the combined AC and DC range, one product family covers hotel corridors, office hallways, apartment foyers and retail perimeters without juggling multiple suppliers.
The built-in 750mm condensate pump is the detail your installers will thank you for. No slope calculations, no hunting for falls across long corridor runs, no call-backs for water stains on fresh ceiling tiles. Hang the unit, connect two pipes and one drain, wire it to a standard 220-240V / 1Ph / 50Hz circuit, and move on to the next one. Both motor tiers share the same body dimensions and G1/2" pipe connections, so crews swap between AC and DC models on the same floor plan without relearning anything.
Choose the DC version — a DC inverter brushless motor with seven fan speeds via the KJR-75A wired controller — and you hand the building owner a unit that draws as little as 14W, cuts fan energy by up to 30% and runs 2-5 dB(A) quieter than the AC equivalent: an easy upsell that differentiates your bid at near-zero extra labour. Power-off memory restores settings after outages, the washable filter pulls out from below in seconds, and Hongtai backs every project with OEM/ODM support — custom voltages from 180-440V at 50/60Hz, project branding, Modbus RTU and BACnet protocols — plus dependable spare-parts supply long after handover.
