Seal-tite WKF36 Support Box Filter Drawer 36 Inches

Product Description

The SEAL-TITE WKF36 is a 36-inch support box designed for air handling systems that require integrated filtration at the unit base. It includes a filter drawer and a side filter rack, giving installers two filtration access points in a single assembly. The support box elevates the air handler to a working height while housing the filter components directly in the support structure. Licensed HVAC technicians and sheet metal installers typically specify this component during new construction or equipment changeout where both unit support and filter access are required in a compact footprint.

The WKF36 is suited for residential and light commercial HVAC installations where a 36-inch support box footprint matches the air handler cabinet width. The integrated filter drawer allows filter changes from the front without moving the unit, and the side filter rack provides an additional filter position for applications that call for multi-stage filtration staging. This unit is commonly installed in closet, utility room, and mechanical room configurations where space efficiency and serviceability are priorities.

Key Features

• 36-inch width matches standard residential air handler cabinet sizes
• Integrated filter drawer allows front-access filter replacement without disturbing the installed unit
• Side filter rack provides an additional filtration stage within the same support structure
• Single assembly combines unit support and filtration housing to reduce installation components
• Designed for closet, utility room, and mechanical room air handler installations

Compatibility

Designed as an OEM-style replacement or new-installation support box for residential and light commercial air handlers requiring a 36-inch base support with built-in filter drawer and side filter rack.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal installer. Power to the air handler must be shut off at the disconnect before setting the unit on the support box and making any electrical or duct connections. Verify that the support box is level before securing the air handler to ensure proper condensate drainage and unit operation. Follow local mechanical codes and manufacturer installation guidelines for load ratings and clearance requirements.
