About this file
This document is a detailed technical submittal for an Air Handling Unit (AHU) for the Southeastern Prison AHU project, specifically Unit Tag AHU 1 ECM. The submittal includes comprehensive engineering specifications for a 39MN Size 17W Aero Indoor Air Handler with multiple technical components including a filter mixing box, hot water coil, draw-thru supply fan, and ECM fan system. The unit is designed with R-13 double wall sealed panels, galvanized exterior and interior finishes, and includes specific configuration details such as a 12-inch plenum, hot water coil with 13.54 sq.ft coverage, and a 2-row 8 FPI full circuit design. The system is configured with six 20in. x 20in. filters (2-inch flat and pleated MERV 8), and is engineered for an actual airflow of 10,700 CFM with a total operating weight of 1,969 pounds.
The technical documentation provides extensive details on the unit's electrical and control systems, including power and controls wiring diagrams for three-phase ECM fans with optional BACnet module capabilities. The air filter submittal highlights a DFpro MERV 8 pleated filter with 100% synthetic graduated density media, featuring a 30-gauge galvanized expanded metal support grid and 96% effective open area. The filter is designed to resist moisture, prevent microbial growth, and maximize dust holding capacity. The system is dated for implementation on 2025-06-30, with all technical specifications subject to change without notice, indicating this is a forward-looking engineering design for a correctional facility's HVAC infrastructure.

Test Port is located Upstream to the Filter. If you would like to add a test port downstream to the filter, add a Downstream Plenum with Test Port.
Discharge duct(s) must be gasketed and screwed directly to the discharge panel of the unit.
** Weights and Dimensions are approximate. Weights include base unit weight, coils (wet & dry), fans and fan motors, and other components, but does not include filters, drives and skids. Approximate dimensions are provided primarily for shipping purposes, for exact dimensions, refer to submittal drawings. Shipping skids are not included.
All filter media efficiency ratings are for the filter media only.

DFpro MERV 8 Pleated Filter
The 100% synthetic graduated density media is continuously bonded to a 30 gauge galvanized, corrosion resistant, expanded metal support grid with an effective open area of 96%. The media is resistant to a wide range of chemicals, does not absorb moisture and will not support microbial growth.
The controlled pleat spacing maximizes surface area and dust holding capacity and is bonded to the enclosure frame to prevent dust bypass. The enclosure frame is constructed of high wet strength moisture resistant beverage board. The diagonal support members of the frame are bonded to the entering and exiting apexes of each pleat to prevent pleat collapse and filter bowing.
