CENTRALISED HEAT RECOVERY UNIT COMPACT SIZE AND SILENT FEATURES & BENEFITS Whole-house heat recovery unit, suitable for vertical installation. Can be installed in cupboard or narrow spaces thanks to its compact sizes. Ease of installation: fixing brackets supplied to hang the unit easily on the wall. • 3 speed with remote control CTRL-S and manual activation of the bypass. Simplified connection: the product is supplied pre-cabled. Outer fan casing manufactured from powder coated galvanised sheet steel providing long lasting and robust construction. The unit is finished in white RAL 9010. Removable front panel for quick access to filters and heat exchanger. Internal structure manufactured from EPP (expanded polypropylene) providing reduced sound emissions and maximised air tightness and thermal insulation. Integral manual bypass for free cooling during the summer season. EC external rotor motors fitted as standard for energy saving. Provided with integral thermal protection, mounted on sealed for life ball bearings. Backward curved centrifugal impeller dynamically balanced and directly driven by the motor to provide a smooth airflow through the unit. Highly efficient exchanger to recovery. counterflow heat maximise thermal G4 filters easy removable for cleaning. External F7 filter cassette on request. Automatic anti-frost protection to prevent frost building up on the intake side of the heat exchanger. Double drain connections holes to meet climate requirement. Tested to the latest standards: units are tested in the TÜV Rheinland recognised laboratory at Aerauliqa, meaning accurate, up to date information on electrical safety, performance and noise level that can be relied upon. Designed and manufactured in accordance with EN60335-2-80 (Low Voltage Directive) and the EMC Directive (Electromagnetic Compatibility). RESIDENTIAL VENTILATION CATALOGUE

QR280M Example of a complete ventilation system Semi-rigid circular ducting Insulated ducting Air extract QR280M Distribution plenum How it works: a continuous running heat recovery unit (QR280M) transfers heat from humid air extracted from wet rooms to warm incoming fresh air which is ducted to habitable rooms. Thanks to the easy-to-fit air distribution system each single ambient can Ø125 Ø125 be properly ventilate: the boost function enables rapid extract of increased moisture or pollutant levels. It also provides discrete installation and very quite operation. Energy saving: the...
