Measure the vacuum at the 1/4" barb using a manometer while the inducer is running

the AX72 maintains structural integrity and resists elongation under heavy loads

this industrial HVAC actuator delivers consistent force to manage moderate mechanical loads even in space-constrained installations

Key Benefits Tool-less Actuator Removal: The iconic PopTop design allows you to snap the actuator on or off for quick maintenance without breaking the line

Optimized for R-410A: Engineered for the higher pressure requirements of R-410A refrigerant to ensure peak thermodynamic performance

Siemens Building Technology GQD156.1P Acutator 323613-751 Measure the vacuum at theThe Siemens OpenAir GQD156. 1P is a high performance, spring return rotary electronic damper actuator engineered for precise control in critical HVAC applications. Delivering a 20 lb in torque (2 Nm) rating, this unit is purpose built for modulating control of small dampers, economizers, and residential zone systems. Operating on a universal 24 VAC DC power supply, the GQD156. 1P utilizes a 2 to 10 VDC modulating control signal with integrated
