Product Sections
DiversiTech 27″ x 48″ Plastic Condensate Drain Pan
The DiversiTech 6-2748L is a large, black plastic drain pan designed to collect condensate from cooling and evaporator coils. Its seamless ABS construction reduces leakage and rust risk over prolonged use. The rolled edges and reinforced corners deliver durability for steady, long-term performance. Best for fixed installations where a robust, seam-free collection pan is needed. Caution: ensure the dimensions fit your unit; overlarge pans can require additional mounting or clearance.
DiversiTech 26” x 26” Plastic Drain Pan, Large
This 6-2626L model offers a compact, square footprint with the same seamless, rust-resistant ABS construction and ribbed bottom for stability. It’s well-suited for mid-size evaporator coils and installations where space is limited. Choose this if you need a dependable, low-profile containment solution. Limitation: not as large as the 27″ x 48″ option, so it may require more frequent monitoring for higher condensate output.
HFYZZ Foldable Drip Pan With Drain Pipe
The HFYZZ model provides a foldable, portable solution with a drain pipe, designed to catch condensate from portable AC units. Made from premium PVC, it’s lightweight, waterproof, and easy to store when not in use. Best for renters or spaces where a removable drip tray is preferred. Caution: foldable design may require careful storage to prevent creases or bending over time.
AMULOKRU Portable Silicone Drip Mat
The AMULOKRU mat uses high-quality silicone to provide a waterproof barrier for portable AC units. Its 23.6″ x 19.7″ size with a 0.78-inch raised edge helps manage condensate and prevent spills. Best for flexible protection across different appliances and easy storage. Limitation: silicone mats can slide on slick floors if not complemented with a non-slip base.
ANLEBUY Silicone Mat With Raised Edge
The ANLEBUY mat is high-grade silicone, designed to be foldable and heat resistant. It features a raised edge to contain condensation. Best for users who want a flexible, no-hole mat that can be bumped or folded without damage. Caution: check dimensions to ensure a snug fit for your unit; oversized mats may impede placement.
BOUTICOL Silicone Drip Pan With Raised Edge
The BOUTICOL portable drip pan provides a large silicone tray with raised edges and non-slip properties. It’s ideal for catching condensate from portable units while protecting floors. Best for broad coverage and ease of cleaning. Limitation: silicone mats may retain odors if not cleaned promptly after use.
