AIR VOLUME CONTROL WITH 1/4" GAUGE
Air volume control with a 1/4" gauge and bayonet coupling. This air volume control is an economical way to set your desired velocity to be achieved by your ventilator fan. Also known as an air-admittance valve (AAV), this valving controls the number of air changes per hour in commercial and industrial HVAC systems.
Manual air volume controls with 1/4" gauge are designed for Johnson Controls EB20 and EB30 Electric Blowers.
This air volume control has a 1/4-inch-inside-diameter gauge and comes with fittings.
The Johnson Controls air volume control is designed for easy application in forced air furnaces for reburners, condensing units and packaged terminal units. The control has a 1/4" NPT port that uses a factory specified adapter to connect to control the combustion air flow of a gas or oil boiler.
The 7882 Series Air Volume Control is a high resistance, pneumatic, diaphragm, air flow control valve. It is typically installed downstream of an air source in order to regulate the air flow through the system. The user is provided with an adjustable level of control that allows them to determine the precise amount of airflow needed for their specific application.
An air volume control for air conditioning, heating, and ventilating systems allows the technician to adjust the volume of blower output. This control typically has a coil spring mechanism and is mounted on the wall or in the ceiling of a conditioned space.
A spring tensioned tool that is intended for use with most popular brands of air compressors. This tool will only increase the volume of compressed air and must be turned to zero before the compressor is started or damage to the gauge could occur.
