About ETRI

ETRI is a compact centrifugal blower product line from Rosenberg Ventilatoren GmbH, specifically designed for applications demanding high airflow performance from minimal installation space. ETRI blowers feature EC (Electronically Commutated) technology for maximum energy efficiency and variable speed control, with backward curved impeller design for aerodynamic performance. The ETRI series is particularly well-suited for air curtain systems, refrigeration evaporator and condenser cooling, compact air handling units, and other HVAC applications where space is constrained but airflow cannot be compromised. Frame sizes range from 133mm to 400mm, covering airflow ranges from 200 to 12,000 m3/h with static pressures from 50 to 500 Pa. ETRI blowers operate directly on 220V/50Hz AC power and are available with 0-10V or PWM speed control inputs. Hengrui is an authorized Rosenberg distributor, supplying genuine ETRI blowers with factory-direct pricing, original spare parts inventory, and engineering consultation for application-specific selection.

Bag

Bag packaging indicates that a specified quantity of product is packaged by the manufacturer in a bag, sealed pouch, or similar container and sold as a unit without repackaging. It is also used to describe kits/assortments where components are packaged in separate bags according to part number or parametric value, rather than in a compartmentalized box or similar rigid container.
