AC drain pan

Product Overview

Every air conditioner that cools also dehumidifies, and that moisture has to go somewhere. The AC drain pan collects condensate from the evaporator coil and guides it to the drain line, protecting the unit, the ceiling and the room. When a pan is poorly made, corrosion, cracks or an incorrect slope can lead to dripping and complaints, which is why brands and service suppliers look for a manufacturer who treats this part as more than a simple tray. Cixi Chenfeng Electric produces AC drain pans with the same attention to forming, welding and coating that we apply to other air conditioning accessories.

Where AC Drain Pans Are Used

• Ceiling cassette units with square or rectangular pans
• Wall-mounted split units with narrow trays beneath the coil
• Ducted and concealed units with pans matched to the coil size
• Floor standing and console units with integrated collection trays
• Auxiliary pans placed under equipment to catch overflow

Materials and Corrosion Control

Condensate is a mild but constant source of corrosion. Galvanized steel provides an economical barrier for standard applications, while 304 stainless steel or coated aluminum is available for units expected to run in humid, coastal or high-usage settings. Surface coatings can be added to protect edges and welds, and insulation can be attached to prevent water forming on the outside of the pan.

Forming Quality and Fit

We use CNC bending, spot welding, TIG welding or deep drawing depending on the pan shape. Corners are sealed, edges are smoothed and drain fittings are placed according to your drawing. Correct slope and depth are held so water flows to the drain without stagnating, which also limits odor and biological growth. Mounting tabs and flanges are designed for accurate seating against coils and casings, reducing assembly effort.

Support for OEM and Service Buyers

OEM customers usually need pans that are consistent across large batches, while service suppliers need parts that match older models. We handle both by working from drawings or samples, producing sample pans for approval and then running batch production with recorded dimensions. Small and medium orders are welcome, and part numbers can be labeled to align with your catalog.

Inspection and Packaging

Each batch is checked for dimensions, seam quality and surface condition, and pans can be leak tested at agreed sampling levels. Packing uses film, paper or foam to avoid scratches, and cartons are marked with part numbers and quantities.

Supply Options for Different Buyer Types

A brand producing thousands of units per month needs a different supply arrangement from a parts distributor handling occasional replacements. For volume buyers we schedule regular production runs, keep tooling in good condition and provide batch records. For distributors and service companies we accept smaller quantities, help identify compatible models from samples and label cartons for easy shelving. In both cases our team keeps communication clear, so you know the status of your order and can plan deliveries to customers with confidence.

Small design details make a large difference in this part. Rounded internal corners reduce dirt buildup, a slightly raised outlet zone helps avoid leftover water, and reinforced rims stop the pan from bending during handling. We are happy to discuss these options with your engineers and apply them to new or existing designs, keeping the pan easy to clean and dependable throughout the lifetime of the air conditioner.
