Applicable to split-system air handlers up to 30 tons, 3/4" or 1" Drain sizes and pressures to -2.5"w.g.
This kit is designed for ducted fan coil air handlers typically located inside commercial buildings.
Applicable to unitary and split-system air handlers up to 100+ tons, 1", 1-1/4", 1-1/2", or 2" drain sizes and pressures to -5.0"w.g.
Each kit is custom-built to operate at the rated pressures inside any unitary or fan coil air handler. The static pressures can be calculated or taken in the field. The designing MEP engineer has the data needed to calculate static pressures and size the CostGard™ Condensate Drain Seal.
Applicable to split-system air handlers, e.g., heat pumps with electric heat, up to 5 ton, 3/4" drain size, and pressures to -1.0"w.g.
This kit is for fan coil air handlers typically located in attics, closets, basements of private homes, and small businesses.
