•MERV 14, 90-95 percent, high temperature rated, cartridge, final filter option—Available on gas and electric heat units with eight foot blank section unit casing option only.
Twelve-inch deep cartridge filters are U.L. Class 1 and are mounted in a galvanized steel casing with a 7/8” nominal thickness header frame. These cartridge filters have an efficiency rating of MERV 14 per ASHRAE 52.2. To ensure maximum cartridge final filter life, high temperature rated two-inch prefilters are included with the cartridge filters. Filters are mounted in a galvanized steel filter frame bank.
•MERV 17, 99.97 percent, standard temperature rated, HEPA, final filter option—Available on cooling only units with four or eight-foot blank section, as well as steam and hot water units with eight-foot blank section, unit casing only.
Twelve-inch deep HEPA filters are U.L. Class 1 and are mounted in a galvanized steel casing. These filters have an efficiency rating of MERV 17 per ASHRAE
52.2and an efficiency of 99.97% on a 0.3 micron DOP particle size. To ensure maximum HEPA final filter life, two-inch prefilters are included with the HEPA final filters. Filters are mounted in a galvanized steel filter frame bank.

Fresh Air
•0 to 25 percent Motorized Outside Air Damper—includes only an outside air opening with moisture eliminator and motorized position damper for drawing up to 25 percent outside air. The damper position can be set at the unit mounted Human Interface panel.
•Economizer—Includes the primary temperature controls necessary to automatically use outdoor air for free cooling. Option includes modulating return and outside air dampers, high ambient temperature lockout, minimum position control and spring return motor.
Standard outside air dampers are provided with a leakage rate of 20 cfm/ft^2 at 1.0 in w.g. pressure difference. Optional Low leakage dampers are available with a leakage rate of 10 cfm/ft^2 (AMCA Class 2) at 1.0 inch w.g. pressure difference, as well as Ultra Low leakage dampers with a leakage rate of 4 cfm/ft^2 (AMCA Class 1) at 1.0 inch w.g. pressure difference.
The 0 to 100% fresh air economizer has three optional economizer controls available: comparative enthalpy, reference enthalpy, or dry bulb control.
•Fresh Air Measurement—The Trane Traq™ airflow-monitoring solution allows direct measurement and control of fresh air. The Traq damper assembly consists of butterfly- type dampers. The bellmouth inlet of each damper guides air uniformly through a flow- sensing ring that accurately measures total and static pressure from 15 to 100 percent of nominal airflow. The damper assembly ventilation control module (VCM) produces a vdc signal that is proportional to airflow, re-calibrates itself once every 60 seconds, and automatically adjusts for temperature variations. When applied as part of an Integrated Comfort™ system (ICS) with the Tracer Summit™ building automation system, ventilation
airflow can be controlled dynamically and documented to verify compliance with ASHRAE Standard 62.1.
•Demand Control Ventilation— When equipped with a CO2 sensor and the (VCM) module, the IntelliPak II controller modulates the fresh air damper position in order to minimize the unit energy consumption yet simultaneously meet the ventilation requirements of ASHRAE Std 62.1. The Traq airflow monitoring solution augments the system, allowing for measurement and control of fresh air airflow.
System Control
•Constant Volume (CV)—Provided with all the necessary controls to operate the air handler from a zone sensor, including CV microprocessor unit control module and a unit mounted Human Interface Panel.
•Variable Air Volume (VAV) Supply Air Temperature control without inlet guide vanes— Provided with all the necessary controls to operate a VAV air handler from the discharge air temperature, including discharge air microprocessor controller and discharge air sensor. The microprocessor controller coordinates the economizer control and the stages of cooling with zone or outdoor air reset capabilities and an adjustable control band to fine-tune the control to specific applications.
•VAV Supply Air Temperature control with inlet guide vanes— Provided with all the necessary controls to control/operate a VAV air handler from the discharge air temperature, including a discharge air microprocessor controller, a discharge air sensor, pressure sensor and inlet guide vanes on the supply fan. The microprocessor controller coordinates the economizer control and the stages of cooling with zone or outdoor air reset capabilities and an adjustable control band to fine-tune the control to specific applications. The inlet guide vanes are used
