Duct supply and exhaust unit OSTBERG HERU 160 S EC-y2 (air flow 720 m³/h)

The ventilation unit with an aluminum rotary heat exchanger is designed for both heated and unheated spaces. It is ideal for installation in homes, offices, and other spaces where strict indoor climate requirements are met. The device's versatility allows it to be installed in both heated and unheated spaces, such as unused attics, thereby saving additional space even in small buildings.

Design

Östberg ventilation units guarantee silent operation due to precision manufacturing, modern technologies, and the highest quality components. Östberg heat exchangers are among the quietest on the market, providing maximum comfort for residents.

Rotary heat exchanger

The ventilation units are equipped with a rotary heat exchanger that provides a high level of both heat and moisture recovery. The advantage of the rotary heat exchanger is its cellular structure, which ensures high heat recovery efficiency—up to 86%. The aluminum rotating drum continuously rotates, extracting accumulated heat from the exhaust air and transferring it to the fresh air drawn in from outside. Thanks to its operating principle, the rotary heat exchanger never freezes, giving it an edge over competing types of heat exchangers.

Advanced filters

Precise F7 class filters capture all pollutants in the air. The efficient F7 class filters used in Östberg ventilation units trap dust, pollen, plant spores, and even smog. Thanks to the use of heat exchangers, the necessary air exchange always occurs, ensuring that the air in the house is always clean and healthy. Fine filtration heat exchangers are especially recommended for allergy sufferers.

Installation

The ventilation unit is equipped with a rotary heat exchanger that provides 86% heat recovery and moisture recovery, preventing the discomfort of the so-called cold winter "dry air." The advantage of this type of heat exchanger is that, due to its construction and operating principle, it does not freeze even in harsh winters.
