Diverse Series 27″ x 48″ Plastic Condensate Drain Pan

The DiversiTech 6-2748L drain pan is a large plastic drip tray designed to collect condensate from cooling and evaporator coils. Its seamless design reduces leakage and resists rust, making it suitable for long-term use in homes and light commercial settings. Best for homeowners or technicians working with standard residential AC condensate needs where a rust-proof, easy-to-clean plastic pan is preferred.
- Material: ABS plastic with rolled edges for added rigidity.
- Seamless construction minimizes leakage risk over time.
- Durable design suitable for continuous use.
Best for: Larger residential systems or packages where easy maintenance and corrosion resistance are priorities. Better for environments where metal pans may corrode over time; avoid if you require metal-over-metal heat resilience in extreme conditions.
Caution: Plastic pans can be less heat-tolerant in high-temperature environments; ensure compatible with your equipment’s condensate temperature range.
DiversiTech 26” x 26” Plastic Condensate Drain Pan

The 6-2626L pan offers a compact, seamless plastic tray designed to catch condensate from evaporator coils in confined spaces. Its rolled edges and ribbed bottom strengthen durability while preserving a leak-free profile. Best for smaller or tight installations where a corrosion-resistant plastic pan is advantageous.
- Plastic, seamless, with rolled edges.
- Non-toxic ABS construction supports safe, long-term use.
- Ribbed bottom adds structural rigidity.
Best for: Small apartments or retrofit projects with limited footprint. Choose this if space is tight and corrosion resistance is a priority; avoid if you need a heavy-load pan or metal durability.
Caution: Ensure the pan size matches your evaporator coil footprint to prevent overflow or misalignment.
GHTCLDF Condensate Drain Pan (Stainless Steel)

The GHTCLDF drip pan uses 0.8mm thick 304 stainless steel for durability and long service life. It features a seamless welded outlet for rapid water removal, and a raised spill-prevention edge at 1.9 inches to prevent drips from reaching walls or floors. Best for households or light commercial spaces needing durable, corrosion-resistant metal pans.
- Material: 304 stainless steel; durable under daily condensate flow.
- Seamless welded outlet ensures leak-free drainage.
- Raised edge minimizes spill risk.
Best for: Installations where long-term metal durability matters; better for heavier condensate loads than plastic pans. Choose this if corrosion resistance is a priority; avoid if you need a plastic, lighter-weight option.
Caution: Stainless steel pans can be more expensive and heavier to install in tight spaces.
Heavy-Duty Galvanized Steel Drain Pan (26″x48″x2″)

This galvanized steel drain pan offers versatile sizing with optional pre-drilled holes. It’s designed to efficiently collect condensate and channel it away to protect buildings from water damage. Best for mid-to-large HVAC installations where a robust metal pan is required and hole options simplify mounting and drainage routing.
- Available with or without pre-drilled holes.
- Rust-resistant galvanized steel construction.
- Effective condensate management for leaks prevention.
Best for: Projects needing a sturdy metal pan with customizable hole options. Better for installers who need precise drainage routing; avoid if you require plastic or lighter-weight options.
Caution: Holes should be properly sealed or matched to the drainage system to avoid leaks.
Heavy-Duty Galvanized Steel Drain Pan (30″x30″x2″)

With the same durable galvanized steel, this 30″ x 30″ pan provides a balanced option for mid-sized HVAC systems. Its hole-option capability supports easier drainage installation in diverse layouts. Best for homeowners replacing older pans or upgrading to a more rugged metal option.
- Size suits mid-sized air handlers and condensate lines.
- Pre-drilled holes available for installation flexibility.
- Durable condensation management reduces leakage risk.
Best for: Mid-sized installations needing a reliable metal pan with optional holes. Choose this if you want a robust pan without oversizing; avoid if your space requires a plastic alternative for weight considerations.
Buying Guide — Key Considerations For HVAC Drain Pans
- Material choice: Plastic pans resist rust but can deform under high heat; metal pans (galvanized steel or stainless) offer higher load capacity and longevity, but may require more mounting care.
- Size and fit: Match pan dimensions to your evaporator coil footprint and available clearance. Oversized pans can trap condensate, while undersized pans risk overflow.
- Hole options: Some pans offer pre-drilled holes for drainage routing or mounting; ensure holes align with your drain line to prevent leaks.
- Durability needs: For harsh environments or commercial settings, galvanized steel or stainless pans can provide long-term resistance to corrosion and wear.
- Installation compatibility: Consider whether existing drainage plumbing and wall clearances support the chosen pan type and height.
- Maintenance: Plastic pans are easy to clean; metal pans may require periodic inspection for rust or corrosion in certain climates.
Frequently Asked Questions
- What is the main factor to choose between plastic and metal drain pans?
Plastic pans are corrosion-resistant and lighter; metal pans offer higher strength and durability, which is important for larger or more demanding installations.
- How do I know what pan size I need?
Measure the evaporator coil footprint and available space; select a pan that fully covers the coil with some clearance for drainage routing.
- Are pre-drilled holes necessary?
They simplify mounting and drainage connections; choose holes that align with your drain line and installation layout.
- Can a drain pan prevent all leaks?
Drain pans reduce overflow risk, but proper installation and drainage routing are essential to prevent leaks.
- What maintenance is required?
Regularly inspect for cracks, rust, or debris buildup; clean pans to prevent mold and ensure unobstructed drainage.
