it ensures precise aerodynamic performance to prevent motor overloading and heat stagnation

the A985 offers a precise fit for specific inter-city products and OEM Lennox or Carrier configurations where a CCW rotation (lead end) is required

start relay

Precision Fit: Designed specifically for 1-inch screw-in elements to ensure a compression seal that prevents water-side bypass and external leakage

Electrical Efficiency: Optimized 208/230 Volt windings provide stable torque across the 3000 RPM range for consistent draft pressure

Siemens Building Technology QAE2020.015 Temperature Sensor L99H008 it ensures precise aerodynamic performanceThe Siemens QAE2020. 015 is a professional grade immersion temperature sensor built for high accuracy fluid monitoring in hydronic HVAC systems. Engineered with a precision 1k ohm Nickel RTD (LG Ni1000) sensing element, this unit delivers a stable output at 32F, ensuring reliable communication with Siemens Desigo, Talis, or any third party Building Automation System (BAS) that accepts an LG Ni input.
