Field Controls Combustion Air Systems
Field Controls Combustion Air Systems (CAS) are an integral component in ensuring the safe and efficient operation of combustion-based appliances in homes and businesses. These combustion blower systems play a critical role in supplying a consistent and controlled flow of fresh air to furnaces, boilers, water heaters, and other fuel-burning devices. By drawing air from the outside, our CAS systems prevent these appliances from depleting indoor air, which could lead to issues like back drafting or simply inadequate combustion. Over nearly a century of innovation and expertise is wrapped into our specialized combustion blowers which have redefined industry standards. Our combustion blowers are engineered to elevate both system efficiency and safety measures due to our unrelenting focus on building the best combustion blowers on the market.

We offer multiple models of the CAS combustion blowers, also known as “Fan in a Can” system, to cater to different heating system sizes and requirements. These models vary in terms of their airflow capacity, dimensions, and other technical specifications.

Discover Field Controls' Draft Inducing Blowers
Field Draft Inducers offer a solution to resolve issues with inadequate drafting due to short chimneys, undersized vent pipes, and negative building pressures. A draft inducer is a fan that is located inside of the furnace near the heat exchanger. Prior to the furnace beginning a heating cycle, the draft inducer will turn on up 30 to 60 seconds before the burners are lit. The draft inducer will continues to run throughout each heating cycle. Because it turns on before the furnace ignites its burners, the draft inducer is able to clear out any combustion gases that might be lingering in the heat exchanger from the previous heating cycle. The remaining gases are pushed into the system flue pipes and vented out of the home. After the burners ignite, the draft inducer continues to run in order to provide the burners with a constant source of oxygen.
Our Draft Inducers are engineered for straightforward installation in a wide array of applications, including oil or gas-fired furnaces to water heaters and boilers. If you need to vent single or multiple appliances, consider employing a control kit for enhanced efficiency.
