Burnham Boiler 81156012 Filter

The Burnham Boiler 81156012 Filter is a critical OEM replacement air filter specifically engineered for high-output combustion systems, including the Evolution Series EV-2000 and EV-2000S. Built to handle the rigorous demands of commercial heating applications, this filter utilizes a heavy-duty paper filter core coupled with a specialized poly pre-filter to maximize particle entrapment. Proper combustion airflow is essential for maintaining a stable fuel-to-air ratio; this replacement boiler filter ensures that contaminants like dust and scale do not compromise the burner or heat exchanger. With a nominal diameter of 14-1/8 inches (including foam) and a thickness of 9-5/8 inches, it provides the precise airflow resistance required for high-efficiency operation. For technicians servicing Evolution series boilers, verifying the foam sealing ring seat is vital to prevent unfiltered air bypass, which can lead to premature component wear or ignition failure. This genuine HVAC part is the standard for maintaining system efficiency and long-term equipment reliability.

• Specifically designed for Evolution Series EV-2000, EV-2000S, and EVA-2000 models for a perfect OEM fit.
• Features dual-stage filtration with a heavy paper media and poly pre-filter to trap fine particulates.
• Maintains clean combustion air, protecting delicate burner components from fouling and scale buildup.
• Supports consistent energy efficiency by ensuring optimal airflow performance throughout the service interval.
• Durable construction with integrated foam sealing to eliminate air leaks and bypass.

Which boiler models are compatible with the 81156012 filter?
This filter is engineered for Burnham and Thermal Solutions Evolution Series units, specifically the 2000 series (EV, EVA, EVS, EVO, and EVOW variants).

How often should this HVAC air filter be replaced?
For commercial heating environments, it is recommended to inspect and replace the filter during annual maintenance or more frequently in high-debris areas to prevent airflow resistance issues.

Can I run my system without the 81156012 filter installed?
No. Operating without a functional combustion air filter can cause damage to the burner assembly and significantly reduce heating system performance.
