VSD VACUUM PUMPS Requirements: • Complete table H1 (for variable torque) or table I1 (for constant torque) of the “Process Systems Incentive Catalog Supplemental Data Sheet” for this measure. • For the “VFD Application” column, enter “Vacuum Pump.” • For the “Controls Before VFD” column, enter “Inlet Control Valve,” “On/Off,” or “Other” and then describe. • For “Controls After” (Constant Torque vacuum pumps only), enter “Automatic” or “Manual.” • VSD vacuum pumps are limited to ≤ 30 HP. Custom incentives may be available for VSD vacuum pumps > 30 HP. • Vacuum pumps must operate a minimum of 2,000 hours annually to be eligible. • Variable torque vacuum pumps are non-positive displacement pumps, including centrifugal blowers and regenerative blowers. • Constant torque vacuum pumps are positive displacement pumps, including reciprocating piston, diaphragm, rocking piston, rotary vane, liquid ring, rotary screw, and lobed rotor pumps.
• Submit manufacturer specification sheet showing the type of vacuum pump that was installed. • Vacuum pumps purchased or installed for backup or redundant systems do not qualify. EQUIPMENT UPGRADES AND RETROFITS Measure Description Code

PRO TIP Dry air is important for your compressed air system to operate smoothly. However, drying air below the dew point required for the specific operation will cause the dryer to work harder, increasing your operating cost.
