Product Name: Blauberg Fresher 50 PIV - Filtered Air Condensation Control Ventilator Fan

Product Description:

The Blauberg Fresher Positive Input Ventilation Supply Air Fan is an exceptional solution for maintaining a fresh and healthy indoor environment. This self-contained, low-energy ventilator fan is equipped with an F8 pollen and allergy filter cartridge, ensuring maximum air purification. With a quiet operation, it silently delivers up to 50 m³/h (14 l/s) of filtered air into your home. The fan boasts a German Blauberg low-energy EC motor, earning an A+ energy rating and backed by a reassuring 5-year Blauberg Warranty.

Key Features:

  • Efficient, low-noise, and energy-saving positive supply air ventilation for flats, houses, apartments, social, and commercial spaces.
  • Equipped with a G4 high-grade synthetic air pre-filter for PM10 (Particulate Matter), general dust, and airborne pollutants.
  • Additional filtration with an F8 high-grade synthetic air filter for PM2.5 (Particulate Matter), pollen, mold spores, fungi, bacteria, and viruses.
  • Speed controllable, remote control, and optional extras like CO2, temperature, or humidity input.
  • Link multiple units to create a whole-house positive pressure system.
  • Acoustic filter media ensures silent operation, as quiet as 13 dB(A) @ 3m.
  • Low-energy EC motor with an A+ energy rating and a specific fan power (SFP) as low as 0.48 w/l/s.


The Blauberg Fresher 50 PIV features a thoughtful design, consisting of a cartridge with filters, an air duct with sound-absorbing material, an indoor unit with a decorative front panel, and an outer ventilation hood. The cartridge includes an energy-efficient EC fan and filters for comprehensive air filtration. In its basic version, the indoor unit comes with automatic shutters that close during ventilator standstill to prevent backdraft. The outer ventilation hood safeguards against water ingress and foreign objects. Optional accessories include a remote control, an extended air duct (700 mm), and various external grilles.

Easy Maintenance:

  • The indoor unit can be easily opened with a gentle press from both sides.
  • Built-in automatic air shutters prevent backdraft.
  • High air cleaning efficiency achieved through a modern filter system.
  • Specially designed front panel ensures 100% tightness and wind protection.


The ventilator can be operated using the sensor control panel on the unit casing or with the included remote control. Additionally, it can be connected to external controls such as a humidity sensor, an external CO₂ sensor, or a switch. Connecting multiple ventilators in series offers effective and optimal ventilation, with the first unit in the series becoming the master unit. Ventilation mode is controlled via the master unit's control panel, and the signal from the remote control is received by the master unit only.


This unit is designed for through-the-wall mounting in a round hole on the outer wall. The installation process in new-construction buildings involves two phases:

  1. Preassembly during the interior and exterior finishing of walls (installation of the air duct, outer ventilation hood, and electrical cable laying).
  2. Final assembly before commissioning the house, including the installation of the cartridge with the fan and filters, as well as the installation and connection of the indoor unit with the controller and air shutters.

Reducing Mold and Condensation with A Blauberg Fresher Wall-Mounted Positive Input Unit

1. Improved Ventilation:

  • Wall-mounted positive input units are designed to bring fresh, filtered outdoor air into the indoor environment.
  • This continuous inflow of fresh air helps dilute and replace the stagnant, moisture-laden indoor air.
  • Improved ventilation ensures that moisture levels are kept in check, reducing the conditions conducive to mold growth and condensation.

2. Controlled Air Exchange:

  • Positive input units operate by pressurizing the indoor space with clean, dry air from outside.
  • This positive pressure helps prevent humid outdoor air from infiltrating the building, which can lead to moisture-related problems.
  • By controlling the air exchange process, these units ensure that indoor humidity remains at an optimal level.

3. Moisture Removal:

  • As fresh outdoor air enters the indoor environment, it carries away excess moisture vapor.
  • This process effectively reduces indoor humidity levels, making it less likely for moisture to condense on walls, windows, or other surfaces.
  • Lower humidity also discourages mold spores from finding suitable conditions to grow.

4. Prevention of Stagnant Air Pockets:

  • Stagnant air pockets in corners or confined spaces can be breeding grounds for mold and condensation.
  • Positive input units distribute fresh air evenly throughout the room, minimizing these stagnant areas.
  • This helps ensure that all areas of the room benefit from improved ventilation and reduced humidity.

5. Filtration and Purification:

  • Many wall-mounted positive input units come equipped with filters that capture allergens, dust, and pollutants.
  • These filters contribute to cleaner indoor air, promoting a healthier and less conducive environment for mold and condensation.
  • Removing airborne particles also reduces the potential for these particles to settle on surfaces and create conditions for mold growth.

6. Humidity Control:

  • Some advanced positive input units can be equipped with sensors that monitor indoor humidity levels.
  • These units can automatically adjust their operation to maintain optimal humidity, further reducing the risk of condensation and mold.
  • When indoor humidity rises, the unit can increase ventilation to expel excess moisture.

In summary, a wall-mounted positive input unit serves as an effective solution to combat mold, condensation, and humidity issues by providing consistent ventilation, controlled air exchange, and moisture removal. These units create a healthier indoor environment with reduced humidity levels, helping to prevent the conditions that promote mold growth and condensation-related problems.
