US Draft Co. is a leading manufacturer of engineered draft control solutions designed to support safe, efficient, and code-compliant venting in modern heating systems.
As boiler and appliance technologies evolve (especially with high-efficiency and multi-unit systems) the complexity of venting has increased. US Draft Co. addresses these challenges with integrated systems that actively manage airflow, pressure, and exhaust behavior.
US Draft Co. Product Line
US Draft Co. offers a complete ecosystem of draft control solutions that work together:
1. Mechanical Draft Inducers (Fans)
These are used to create or stabilize draft when natural draft alone is not sufficient. Products like inline and termination fans actively move exhaust gases through the venting system, ensuring proper flow even in complex or long vent runs.
2. Dampers (Draft Regulation Devices)
Dampers modulate airflow and pressure within the vent system. By adjusting how much air moves through the system, they help maintain consistent draft and prevent issues like overdraft or backdrafting.
3. Controls (System Intelligence)
US Draft Co.’s control systems act as the “brain” of the operation. Using pressure sensors and responsive control logic, they continuously monitor and adjust system performance to maintain target draft conditions, even as loads or environmental factors change.
4. Integrated Draft Control Systems
These components come together in engineered systems designed for specific applications, including:
- Vent Control Systems (VCS): Maintain constant pressure in a chimney or common manifold
- Overdraft Control Systems (ODCS): Prevent excessive draft that can reduce efficiency
- Pressure Air Systems (PAS): Ensure proper combustion air supply in mechanical rooms
- Connector Draft Systems (CDS): Control draft at the individual appliance level
Each system is designed to maintain consistent pressure and respond dynamically to real-world operating conditions.
Why Draft Control Systems Are Important
Draft control is not just a technical detail, but something that directly impacts how a boiler system performs.
Without proper draft control, systems can experience:
- Fluctuating combustion performance
- Reduced efficiency and higher fuel consumption
- Equipment strain and shortened lifespan
- Safety risks from improper exhaust flow
US Draft Co.’s systems are designed to maintain stable, consistent pressure throughout the venting system, even as conditions change. This is especially critical in:
- Multi-boiler or common vent systems
- High-efficiency condensing applications
- Buildings with variable load conditions
- Retrofits where existing venting may be inconsistent
By actively managing draft instead of relying on passive venting alone, these systems help ensure that appliances operate as intended.
Designed for Modern Heating Systems
Today’s heating systems are more efficient, but also more sensitive to venting conditions. Lower flue gas temperatures, tighter building envelopes, and shared venting configurations all introduce new challenges.
US Draft Co. addresses these with technologies that:
- Continuously monitor system pressure
- Adjust airflow in real time
- Interlock directly with heating appliances
- Maintain code-compliant operation across varying conditions
The result is a venting system that adapts, rather than one that relies on ideal conditions to perform.
