Koch Filter 76B0005N19 Pleated Air Filter 30x32x2 Geothermal

Product Description

The KOCH FILTER 76B0005N19 is a pleated air filter engineered for geothermal HVAC systems that require oversized filtration media. The pleated construction increases usable surface area compared to flat-panel media, allowing the filter to capture more airborne particulates while sustaining adequate airflow through geothermal air handlers and ducted equipment. At 30 inches by 32 inches by 2 inches, this filter addresses the non-standard filter bays common in geothermal unit configurations. Licensed HVAC technicians and geothermal system installers are the primary audience for this part.

This filter is intended for geothermal heating and cooling systems that use oversized filter housings not accommodated by standard residential filter sizes. Geothermal air handlers often specify larger-format filters to match their higher airflow capacity and to extend service intervals between filter changes. The 2-inch depth provides additional media volume over 1-inch alternatives, supporting longer maintenance cycles in occupied residential and light commercial installations.

Key Features

• Pleated media design increases surface area for improved particle capture versus flat-panel filters
• Oversized 30 x 32 x 2 inch format fits geothermal air handler filter bays
• 2-inch media depth supports extended service intervals compared to 1-inch filters
• Maintains proper airflow through geothermal HVAC equipment
• Designed as a direct-fit replacement for systems specifying part 76B0005N19

Compatibility

Designed as an OEM-style replacement pleated air filter for geothermal HVAC systems requiring a 30-inch by 32-inch by 2-inch filter format.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with geothermal system service procedures. Power down the air handler at the disconnect or breaker before removing the old filter and installing the replacement. Confirm airflow direction markings on the filter frame align with the direction of airflow in the housing before securing the access panel. Follow local mechanical codes and the equipment manufacturer's maintenance schedule for filter replacement intervals.
