Description

Product Part Number

BSK-Zephyr-Plus

Product Overview

The BSK Zephyr Plus is a high-performance decentralized heat recovery ventilation unit designed to provide continuous fresh air to individual rooms without the need for a traditional centralised ducted ventilation system.

Ideal for residential properties, renovations, apartments and light commercial applications, the Zephyr Plus combines heat recovery, low-energy EC fan operation and intelligent humidity and temperature sensing within a compact through-wall unit.

During operation, stale indoor air is extracted through the unit while the ceramic heat exchanger captures and stores thermal energy from the outgoing air. The airflow then reverses, drawing fresh outdoor air back through the ceramic core where the stored heat is transferred to the incoming air. This alternating process helps maintain a comfortable indoor temperature while reducing the heat losses associated with conventional extract ventilation.

With airflow rates of up to 100 m³/h, thermal efficiency of up to 90%, four fan speed settings and very low power consumption, the Zephyr Plus provides an energy-efficient solution for improving indoor air quality and controlling excess moisture.

How the Zephyr Plus Works

The Zephyr Plus operates using an alternating airflow cycle. During the extract cycle, warm stale air from inside the room passes through the ceramic heat exchanger, transferring heat energy into the ceramic core.

The fan then reverses direction and draws fresh outdoor air through the same heat exchanger. The stored thermal energy is transferred to the incoming fresh air before it enters the room.

This regenerative heat recovery process allows the Zephyr Plus to continuously refresh indoor air while recovering up to 90% of the heat that would otherwise be lost through conventional ventilation.
