Carrier AirStream 40U Unit Ventilators

The Utmost in Product Flexibility

The overall environment in classrooms is vital to the learning process. Without the discomfort and distraction of high noise levels, damp or dry air, pollutants or temperature variations, students can learn better and faster. How do you create such an environment and at the same time, minimize your investment, energy use and operating costs? By making AirStream™ unit ventilators part of your heating and cooling system.
Carrier’s AirStream unit ventilators operate with sensitive controls, so that you can open the room to outside fresh air as needed and the controls will determine the correct blend with conditioned air to provide a safe, comfortable learning environment. In either vertical or horizontal configurations, AirStream units are cost-efficient and easy to install and maintain. AirStream units are designed to provide occupants with the ultimate in quiet and comfort.

FLEXIBILITY
AirStream unit ventilators come in both vertical and horizontal configurations to conform to a variety of room layouts, providing optimal comfort levels with flexible installation alternatives. Vertical units are typically mounted against an exterior wall or under a window, in either a classroom or a hall. The horizontal configuration models can be ceiling-mounted, either fully exposed or recessed.

EFFICIENCY
Carrier’s AirStream unit ventilators have few moving parts, which helps to lower operating costs by enhancing reliability and making service easier. Full-diameter, permanently lubricated ball bearings align the blower shaft, reducing sound, and do not require scheduled service. A one-piece outdoor/return air damper incorporates a dual-blade seal for positive control of ventilated air and better seals against cold outside air.

QUIET OPERATION
AirStream units are built to operate unobtrusively, with quiet motors and fans. A rugged, rigid construction also ensures vibration-free operation, providing leading sound levels as low as 8 dB lower than previous designs.

DURABILITY
Carrier’s AirStream unit ventilators have a modular chassis fabricated from heavy-gauge, die-formed galvanized steel, which prevents deformation and inhibits corrosion. Each unit’s sturdy frame resists vibration and ensures correct alignment of the fan shaft and bearings. All coils are constructed of copper tubing that is mechanically bonded to corrugated aluminum plate fins. For ease of maintenance, the modular design allows components to be removed without disassembling the unit.

THE RIGHT LEVEL OF CONTROL
AirStream unit ventilators achieve their full potential and capability to tie both temperature controls and CO2 air-quality sensors together when they operate as part of the Carrier i-Vu Open control system, a fully-integrated BACnet® building automation system. The unit ventilator plug-and-play controller interface provides heating, cooling, ventilation, and dehumidification functions for total environment control. It’s the Carrier’s total heating, ventilation, and air-conditioning (HVAC) air quality solution. Two efficient methods of providing air comfort, valve control or face and bypass control can be selected. Unit ventilators can be supplied with factory- mounted Carrier or third-party controls to meet any application. Controls can comply with ASHRAE® control cycle I, II, or III recommendations. Standard with Carrier unit vent open controls, electronically commutated motors (ECMs) have higher efficiency and are automatically controlled to adjust their speed to compensate for variable resistance in the air stream, such as dirty filters. Thus, the unit ventilator will reliably deliver its nominal airflow rate (±5%) at each defined speed. For all your comfort needs, Carrier has the right level of control.
