Dayton Downflow Diffuser

The Dayton 5PV75 is a downflow radial discharge diffuser built for unit heaters. It attaches to compatible heaters to spread warm air across the space. The steel construction and gray finish suit commercial and industrial installations. Buyers who need a different airflow pattern or a non-steel housing should look elsewhere.

Capacity and coverage

The diffuser measures 21 1/16 in overall height, 16 3/4 in width and 9 3/4 in depth. It handles the airflow delivered by matching unit heaters without added restriction. Larger areas requiring wider throw or higher volume will exceed what this single diffuser can supply.

Compatible heater models

This diffuser is confirmed for Grainger part numbers 5PV54 and 5PV55 and manufacturer model numbers 54 and 55. A hardware kit is included for installation. Heaters with different model numbers or mounting patterns are not supported by this part.

Questions about this item

Will this 21 1/16-inch tall diffuser fit my existing Dayton unit heater that uses part numbers 5PV54 or 5PV55?

Yes, the specifications list compatible manufacturer model numbers 5PV54 and 5PV55, and the compatible Grainger part numbers are the same 5PV54 and 5PV55.

How can I verify the closed-base steel diffuser is directing air radially across the room after I mount it?

Stand to the side of the unit heater and confirm air moves horizontally away from the grey steel grille at the 16 3/4-inch width rather than dropping straight down.

Does the box include the mounting hardware kit mentioned in the description, or do I need to order brackets separately?

The product details state the package includes a hardware kit, so no separate brackets or fasteners are required for installation.
