G2E160-AY47-01: High-Performance Single Inlet Blower
The G2E160-AY47-01 is a robust centrifugal blower from ebm-papst, featuring a single-inlet scroll housing. This 160mm unit is designed with forward-curved blades (often referred to as a Sirocco impeller), which allows it to generate a substantial volume of air relative to its compact physical size. The galvanized sheet steel housing (scroll) efficiently converts the dynamic velocity of the air into static pressure, directing the airflow out through a flanged outlet. This specific model is powered by a 2-pole single-phase AC external rotor motor, ensuring high-speed operation and reliable performance in industrial environments.

Lifecycle & Maintenance Diagnosis
Lifecycle State: Active. This blower is a critical component in many industrial burners, localized cooling systems, and air curtains. Diagnosis: A common issue with forward-curved blowers is current overload if operated without backpressure («free blowing»). If the motor runs hot and trips the thermal protection, check that the ductwork is connected; these fans need resistance to operate within their curve. Also, verify the capacitor condition annually, as high-torque starts can degrade it over time. Installation Tips: Ensure the outlet flange is sealed correctly to prevent pressure loss. The motor is mounted on vibration-damping grommets; check these for dry rot in older units to prevent noise transfer to the machine chassis. Compatibility: Compatible with Siemens LOGO! relay outputs for burner control sequences. It can also be speed-controlled via voltage reduction (transformer) to adjust air/fuel ratios in combustion applications.
