Rectorseal AH17 Air Handler Filter Cabinet 17 Inches

Product Description

The RECTORSEAL AH17 is a ready-to-assemble air handler filter cabinet designed for HVAC systems requiring flexible-height filtration solutions. Constructed from galvanized steel, this knock-down cabinet ships flat and assembles quickly in the field, reducing staging time on residential and light commercial jobs. The cabinet adjusts from 4 inches to 18 inches in height, allowing it to adapt to varying equipment configurations without custom fabrication. When installed without the filter door, the AH17 functions as a booster box, giving HVAC technicians added installation flexibility across a range of system setups.

The AH17 is suited for residential and light commercial HVAC installations where a compact, field-adjustable filter cabinet is needed. It is commonly installed as part of an air handler system in place of standard 4-inch media air cleaners. The patented knock-down design makes it practical for technicians who stock multiple units, as the flat-pack carton reduces van and warehouse space requirements. The cabinet can be used with or without a filter door depending on the application and system airflow demands.

Installation Notes

Installation is typically performed by a licensed HVAC technician. Power to the air handler must be shut off at the disconnect or breaker before beginning any cabinet installation or modification work. Follow local mechanical codes and the equipment manufacturer guidelines for filter cabinet sizing and airflow clearance. When configuring the cabinet as a booster box without the filter door, verify that the open configuration is appropriate for the system design and does not compromise filtration requirements.
