## Long description

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.
