The Problem
Overheating or overcooling problem areas?
As heating and cooling zones grow larger budget constraints cause multiple work spaces to be controlled
by a single thermostat. This causes system efficiency to suffer and occupant complaints to increase.
“Thermostat Wars” result as occupants attempt to adjust the thermostat to their own level of comfort.
Receptionist Areas & Entry Ways
These spaces are typically exposed or open and cooling is often “dumped” in this area which causes
overcooling problems and receptionist discomfort.
Offices
Often times, people inhabiting offices in the same zone have different requirements for comfort. This can
lead to “Thermostat Wars” as well.
Conference Rooms
Peak cooling is needed for larger meetings, but not during normal use or when unoccupied. Building owners
don’t want to pay to cool during unoccupied times, nor do they want a full-blown zoning system.
East/West Exposure
East side building exposure is too hot in the morning, then cold in the afternoon. Then conversely, the West
side building exposure is cold in the morning and too hot in the afternoon. Without proper zoning, this can
lead to discomfort.
Performance Aire offers three
VAV comfort solution packages.
VAV Thermal Diffusers
While energy costs continue to rise, VAV Thermal Diffusers remain an energy free
solution to individual comfort control. No wiring, pneumatic piping, or added system
pressure is required. Our diffusers are self-contained with the thermostatic control
device and damper in each diffuser. Existing systems are easily upgraded with the
various diffusers available. Our square and linear diffusers have been providing
occupant comfort in offices, schools, hospitals and retail centers for over 25 years.
VAV Digital Electronic Diffusers
Our VAV Digital Electronic Diffusers incorporate a modulating damper that regulates
the volume of supplied air in response to a wall mounted thermostat. The diffuser
automatically senses the need for heating or cooling modes. It can be installed as
a master/drone with up to 36 drone diffusers for each master (zone). BACnet digital
thermostats are available as an option. Control of the diffuser is via a wall-mounted
thermostat, enabling users to set desired comfort control from desk top level.
VAV Air Terminal Units
Performance Aire VAV Air Terminal Units are designed to regulate the flow of
conditioned air in a distribution system. They work equally well in constant and
variable volume systems. Control is via a low leakage single blade damper seal
for use in pressure dependent and pressure independent applications.
VAV Thermal Diffusers
Square Plaque Solution
General System Applications
SC square diffusers are applied to cooling
only VAV systems requiring high
volume/short throw.
SCAH square diffusers are applied to
cooling only VAV systems with an adjustable
warm air volume control override.
SCVH square diffusers are applied to
provide cooling and heating VAV control
where the application requires a high
volume/short throw.
Features
• Control functions that automatically adjust temperatures in individual workspaces.
• No control wiring, pneumatic piping, or added system pressure required.
• Existing systems are easily upgraded with the various diffusers available.
• Separate and adjustable set points for heating and cooling.
• Easy access set point adjustment.
• Diffuser constructed of 24 gauge
sheet steel.
• Architecturally pleasing, blemish free hemmed face panel.
• Cone shaped diffusion damper.
• 10 year warranty.
Induction Path
>
Diverts a small amount of supply air causing
the induction of a sample of room air to be
drawn through the induction trough directly
across the temperature control sensors.
Easy access to set point adjustment.
Separately adjustable set-points for
VAV heating and VAV cooling control
VAV Thermal Diffusers
Linear Slot Solution
LAD
General System Applications
LAD linear diffusers are applied to provide
horizontal cool air/vertical warm air diffusion
for exterior spaces when room temperature
control is not required.
VACH
Application of LAD Diffusers
The application of the LAD diffuser over entry
doors is highly recommended. Vertical warm air
flow will greatly enhance the comfort level in the
same fashion as an air wash.
VAC linear diffusers are applied to VAV
cooling room temperature control systems.
VACH linear diffusers are applied to provide
horizontal VAV cooling/vertical VAV heating
room temperature control for exterior spaces.
Features
• Automatic change over knows when to adjust the flow from horizontal cooling
to vertical heating.
• Existing systems are easily upgraded
with the various diffusers available.
VAV Digital Electronic Diffusers
Square Plaque Solution
General System Applications
SE-HC-M
SE-HC-M
The model SE-HC-M VAV Diffuser includes a diffuser
and modulating actuator. The SE-HC-S can be used as
an auxiliary damper when wired to a SE-HC-M diffuser
actuator in applications where more than one diffuser is
required in a single zone. Up to 36 drones can be added
to one master.
The Performance Aire VAV Digital Electronic
Diffuser incorporates an internal modulating
disk that continually regulates the volume
of supply air in response to a wall-mounted
thermostat.
The Performance Aire VAV Digital Electronic
Diffuser is designed to maintain the Coanda
effect of discharging air along the ceiling,
providing draft free mixing throughout
the space.
Features
• Wall-mounted thermostatic control.
Individual zone control from a wall
mounted thermostat.
• Powerful, low voltage actuator.
Floating-point actuators are standard.
• True variable air volume in heating and
cooling modes. The diffuser effectively
regulates the amount of supply air into
the space and uses a wall mounted
thermostat to achieve true VAV control in
heating mode, as well as cooling mode.
Automatic change over from heating to
cooling is standard.

Actuator
S-T Thermostat
The Performance Aire S-T Thermostat is designed
to work with the modulating zone control system
and the stand-alone modulating zone damper
and diffuser.
S-T Thermostat
NETstat Thermostat
The Performance Aire NETstat is a BACnet enabled thermostat that
combines a controller, multiple sensor options and BACnet networking
into a single, integrated space-mounted device.
The NETstat thermostat offers a unique, cost-effective
combination of networking, application and sensor
options, along with easy, intuitive installation,
configuration and operation.

VAV Air Terminal Units
Single Duct/Round Retrofit Solution
General System Applications
Model PH Series
Model PH
Series
Single duct air terminal units, model PH are
designed to regulate the flow of conditioned
air in a distribution system.
Single duct air terminal units work equally well
in constant and variable volume systems. The
Model PH Series is recommended for use in
duct systems with static pressure up to 4” wg.
Features
• Units can be specified with hot water coils,
access panels, control enclosures and
multiple insulation choices.
• A low leakage single blade damper with
integrated blade seal for pressure
dependent or pressure independent
applications.
Ductwork
• Available in sizes 4” to 16” round and
20” x 16” rectangular inlets.
Model PT Series
The round retrofit air terminal unit model PT
is designed to regulate air flow of conditioned
air in single duct or dual duct air distribution
systems.
VAV Box
Model PT
Series
The round retrofit ATU is also used to provide
positive or negative pressures in laboratory
flow hood applications.
The Model PT is primarily used to convert
constant volume single or dual duct air
terminals to more efficient variable volume
air terminals without disrupting the total
system operation.
The round retrofit ATU is easily installed
into existing ductwork in front of the existing
air terminal.
Features
• Available in sizes 4” to 16” round.
