<strong>Single</strong>-<strong>Duct</strong>, <strong>VAV</strong> <strong>Terminals</strong> CATALOG: ET<strong>130.13</strong>-<strong>EG1</strong> (1212)GUIDE SPECIFICATIONSPneumatic ControlsUnits shall be controlled by a pneumatic differentialpressure reset volume controller. Controller shall becapable of pressure independent operation down to0.03 inches W.G. differential pressure and shall befactory set to the specified airflow (CFM). Controllershall not exceed 11.5 scim (Standard Cubic Inches perMinute) air consumption @ 20 PSIG.Unit primary air valve shall modulate in response to theroom mounted thermostat and shall maintain airflow inrelation to thermostat pressure regardless of systemstatic pressure changes. An airflow (CFM) curve shallbe affixed to the terminal unit expressing differentialpressure vs. CFM. Pressure taps shall be provided forfield use and ease of balancing.Terminal unit manufacturer shall supply and manufacturea 5 to 10 PSIG pneumatic actuator capable of aminimum of 45 in. lbs. of torque.Actual sequence of operation is shown on the contractdrawings. Terminal unit manufacturer shall coordinate,where necessary, with the Temperature ControlContractor.28 ENVIRO-TEC
