Viessmann 7831028 Radial Fan
The Viessmann 7831028 Radial Fan is a critical combustion air blower component designed for high-efficiency boiler systems, specifically the Vitodens 200 and Vitodens 300 series. As an RLS154 radial fan, this unit is engineered to manage precise air-fuel ratios required for condensing boiler modulation. This specific SKU is provided without electrics, meaning the housing and impeller assembly are intended for field-integration with your existing Viessmann fan motor and control module. When troubleshooting a Viessmann burner fault or ventilation failure, verifying the mechanical integrity of the centrifugal impeller is vital. This OEM Viessmann replacement part ensures exact structural compatibility with the combustion chamber manifold, maintaining factory-spec static pressure and airflow velocity. Utilizing genuine HVAC blower components prevents the common resonance and vibration issues associated with aftermarket radial fans in residential and commercial thermal applications.
Technical Benefits for Contractors:- Direct OEM Fit: Engineered specifically for the Viessmann 7831028 specification, ensuring zero-gap seating against the air intake housing.
- Variable Speed Compatibility: Optimized for modulating boiler systems that utilize pulse width modulation (PWM) signals for airflow control.
- High-Efficiency Impeller: The RLS154 wheel design reduces mechanical drag, optimizing the electrical load on the existing fan motor.
- Flexible Integration: The "without electrics" configuration allows technicians to replace failed mechanical bearings or warped impellers while retaining functional electronic control boards.
Does this unit include the fan motor or PCB?
No, the Viessmann 7831028 (RLS154) is the mechanical fan assembly only. You must transfer your existing electrical components or source them separately.
Which boiler models are compatible with this radial fan?
This part is commonly found in Viessmann Vitodens condensing units. Technicians should verify the part number against the boiler’s data plate and the specific RLS154 model number on the existing fan housing.
What are the signs of a failing radial fan in a boiler?
Common indicators include loud bearing noise, "Air Pressure Switch" fault codes, or the boiler failing to initiate the pre-purge cycle during the ignition sequence.
