Lukjan CA50291706A Furnace Filter Cabinet 17.5x29x6

Product Description

The LUKJAN CA50291706A is a furnace filter cabinet designed for installation in residential forced-air heating and cooling systems. This sheet-metal box mounts inline with the return-air duct or air handler to house a standard deep-media or pleated filter. At 17.5 x 29 x 6 inches, it accommodates a filter of that nominal face size and 6-inch depth, which is typical of high-capacity media filters used to extend service intervals between maintenance calls. HVAC technicians and sheet-metal installers fit these cabinets during new construction and retrofit projects where a dedicated filter housing is needed outside the unit cabinet.

This filter cabinet is suited for residential forced-air systems where a remote or inline filter location is preferred over a rack inside the furnace or air handler. It is commonly installed in basement utility rooms, mechanical closets, and attic platforms. The 17.5 x 29 inch face opening fits standard nominal-sized deep media filters, and the 6-inch depth provides room for high-MERV media blocks that offer longer run times between changes compared to 1-inch or 2-inch disposable filters.

Key Features

• 17.5 x 29 x 6 inch interior dimensions sized for deep-media or high-MERV pleated filters
• Inline filter cabinet design keeps the filter accessible without opening the air-handler cabinet
• Sheet-metal construction typical of LUKJAN duct fabrication products
• Sized for residential forced-air return-air duct applications

Compatibility

Designed as an OEM-style replacement and new-installation filter cabinet for residential forced-air furnace and air-handler systems with return-air ductwork sized to accept a 17.5 x 29 x 6 inch filter box.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet-metal contractor. Shut off all power to the air handler or furnace at the disconnect and thermostat before cutting into return-air ductwork. Seal all seams with UL-listed foil tape or mastic per local mechanical code to prevent unfiltered air bypass. Ensure the cabinet is oriented so the filter slides in and out without obstruction for routine maintenance access.
