When an air handler is laid on its side, the drain pan geometry changes to keep condensate flowing toward the drain outlet — this pan is shaped specifically for that horizontal coil position so water never pools or backs up into the cabinet.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOrientation: Horizontal air handler configuration\u003c\/li\u003e\n\u003cli\u003eMaterial: Corrosion-resistant molded composite\u003c\/li\u003e\n\u003cli\u003eSloped base for positive condensate drainage\u003c\/li\u003e\n\u003cli\u003eFits: Goodman WAHMS3642P4ABA air handlers\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1756028L\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eHorizontal pans are far less forgiving than universal pans because the slope and outlet position must match the coil exactly.
