Heat recovery ventilator SpiroFlex Rekuperator poziomy VENT CLEAR HD4 HR Comfort Plus 465 m3/h

SpiroFlex Rekuperator poziomy VENT CLEAR HD4 HR Comfort Plus 465 m3/h is a horizontal heat recovery ventilator designed for controlled ventilation in residential and small commercial environments. With a nominal airflow of 465 m3/h, the unit performs balanced supply and extract ventilation through ducted installation while recovering heat from exhaust air to reduce heating demand. The compact horizontal layout allows installation in attics, ceilings or mechanical rooms where space and duct routing require a low-profile solution.

Advantages

The unit provides continuous balanced ventilation with heat recovery to improve indoor air quality and reduce energy consumption. It includes features intended for reliable year-round operation: efficient heat exchange between supply and exhaust streams, support for ducted distribution, and capacity suited to medium-sized living spaces or small commercial zones. Noise levels and airflow are engineered to maintain comfortable conditions while providing consistent air exchange.

Suitable for

• Residential apartments and houses requiring balanced mechanical ventilation
• Small offices and commercial premises with ducted ventilation systems
• Renovation projects where a horizontal, low-profile unit is needed for attic or ceiling mounting
• Spaces where heat recovery is required to lower heating costs and maintain indoor air quality

Key specifications

• Nominal airflow: 465 m3/h
• Configuration: horizontal heat recovery ventilator for ducted systems
• Function: balanced supply and extract ventilation with heat recovery
• Installation: designed for attic, ceiling void or mechanical room mounting with horizontal duct connections
• Application: residential and small commercial use

How to use

Install the ventilator in a horizontal position following local ventilation guidelines and the manufacturer’s mounting instructions. Connect supply and extract ducts to the designated horizontal inlets and outlets, ensuring airtight duct joints and appropriate insulation where needed. Integrate the unit with the building’s electrical supply and controls to enable continuous or demand-controlled operation. Verify airflow balance and adjust settings or dampers as necessary to achieve the intended supply-to-extract ratio and to optimize heat recovery performance.

Usage recommendations

For reliable performance, schedule regular inspections of filters and heat exchange surfaces and replace or clean filters according to operating conditions. Ensure ducts remain unobstructed and sealed to maintain airflow and energy efficiency. When installing in cold climates, follow guidance for condensate handling and insulation to prevent heat loss or frost in the heat exchanger.
