Trans/Air 301618 Micro-Channel Condenser Coil (3-Fan) | Fits SMC Series Skirt Mount & Roof Units | Aluminum MCHX Replacement Core | Fixes Leaking Bus A/C | School Bus & Shuttle

Restore Your High-Capacity Bus A/C.The Trans/Air 301618 is the OEM replacement coil for larger 3-Fan Condenser Units. These high-performance units are the workhorses of the school bus and transit fleet, but their location (often skirt-mounted) makes them vulnerable to damage.The "Road Hazard" Fix: If your condenser sits behind the rear wheels, it takes a beating from rocks and road salt. Once a Micro-Channel (MCHX) coil is compromised, it cannot be reliably patched. This 301618 Aluminum Core is the factory-correct replacement to stop the leaks and restore cooling efficiency.Compatible Applications: System: Trans/Air 3-Fan Condensers (SMC Series) Mounting: Skirt Mount or Rooftop Vehicles: School Buses, Motor Coaches, Large ShuttlesTechnical Specifications: Type: Micro-Channel (Brazed Aluminum) Fans: 3-Fan Configuration Manufacturer: Trans/Air (Lippert)

• FIXES LEAKING 3-FAN CONDENSERS: Genuine Trans/Air 301618. The heavy-duty Micro-Channel (MCHX) coil designed for Trans/Air **3-Fan** condenser configurations (often found in SMC Series Skirt Mount units). Replaces cores damaged by road debris or salt corrosion.
• THE "UN-REPAIRABLE" SOLUTION: Modern Micro-Channel aluminum coils provide superior cooling but are extremely difficult to braze or patch once punctured. Replacing the entire core is the industry standard to ensure the A/C system holds its charge.
• DESIGNED FOR SKIRT MOUNT ABUSE: Engineered to withstand the harsh environment of under-floor "Skirt Mount" installations where condensers are exposed to constant road spray, gravel, and de-icing chemicals.
• FITS LARGE BUS APPLICATIONS: Compatible with high-capacity A/C systems on 40-foot School Buses (IC, Thomas & various other models) and large Transit Coaches requiring maximum heat rejection.
• OEM LIPPERT / TRANS/AIR QUALITY: Direct factory replacement ensuring alignment with the 3-fan shroud and existing refrigerant plumbing. (Dimensions: Verify footprint matches your existing 3-fan block before ordering).
