Outside Air Units are designed to be mounted outdoors. The 5¼” UV-resistant plastic shield keeps the sensor out of the sunlight and allows for excellent air circulation. The Outside Air Unit comes standard in a Weather Tight (EU) UV-resistant enclosure which carries an IP 66 rating (similar to NEMA 4X) and is light in color to reflect sunlight and minimize reading error. Outside Air Units are also available in a cast aluminum Weatherproof (WP) enclosure which carries a NEMA 3R rating.

All Outside Air Units have etched Teflon leadwires and double encapsulated sensors to create a watertight package that can withstand high humidity and condensation and perform under real world conditions. This is especially important in an outside air application which can be exposed to rain, snow and large temperature swings.
