the RCC-1504 features a high-capacity air flow of 1728 scim at 20 PSI

Zonefirst IOBD-12X6 Damper R-410A and 277VAC circuitsThe Zonefirst IOBD 12X6 is a professional grade 12" H x 6" W Opposed Blade Damper engineered for high performance HVAC zone control applications. Built for technicians who prioritize precision airflow, this unit utilizes an opposed blade configuration to minimize turbulence and provide a more linear flow characteristic than standard parallel blade dampers. The assembly features an internally mounted motor, which protects the 24Vac actuator from
