Laars Heating Systems R2004500 Filter
Professional-grade combustion performance begins with high-quality air filtration. The Laars Heating Systems R2004500 Filter is a critical OEM replacement part engineered specifically for high-efficiency boilers and volume water heaters. This washable air inlet filter is constructed from durable open-cell polyurethane foam, designed to capture airborne particulates and debris before they enter the combustion chamber. By maintaining a clean combustion air intake, this component protects the blower motor and burner tray assemblies from premature wear and fouling, ensuring consistent manifold pressure and optimal fuel-to-air ratios.
Sized at approximately 17.2" x 10.65" x 2.95", the R2004500 inlet filter provides a precise fit for the Laars Rheos (models 1200-2400) and Laars Pennant series. It also serves as the direct replacement for part A2108300. For technicians servicing commercial hydronic systems, regular inspection of the intake media is vital to prevent vacuum switch errors and "soft" lockouts caused by restricted airflow. This heavy-duty filter is built to withstand the high-demand environments of mechanical rooms while supporting the four-stage firing sequences of modern Laars heating systems.
Key Benefits:
- Optimized Airflow: High-porosity open-cell foam ensures maximum CFM delivery to the blower without overworking the motor.
- Broad Compatibility: Direct fit for Laars Pennant and Rheos boilers, ensuring seamless HVAC part replacement.
- Washable Media: Environmentally friendly and cost-effective design allows for cleaning and re-installation during routine maintenance.
- Component Protection: Shields sensitive internal combustion components from dust, dirt, and construction debris.
- OEM Reliability: Ensures the unit maintains its original AHRI efficiency ratings and emission standards.
Common Questions:
Is the R2004500 filter interchangeable with previous Laars part numbers?
Yes, the R2004500 is the current manufacturer-specified replacement for the older part number A2108300.
How often should I clean or replace the air inlet filter on a Pennant boiler?
While service intervals depend on the site environment, technicians should inspect the filter during every annual preventive maintenance check. If the foam appears brittle or if the boiler airflow is restricted, immediate replacement is necessary.
What happens if the boiler is operated without this air filter?
Operating without the R2004500 allows debris to accumulate on the burner ports and blower wheels, which can lead to inefficient combustion, increased carbon monoxide production, and mechanical failure.
