SoffitFlow 4" Soffit Exhaust Vent

Introducing SoffitFlow^TM, a smart venting solution designed to expel hot, humid bathroom fan exhaust in an outwards direction, beyond the fascia. Warm air naturally rises and SoffitFlow channels the humid exhaust away from the home, reducing the danger of mold and moisture buildup in the attic space — the leading cause of wood rot and structural damage.

Quality constructed in the USA, this patented innovation (USPTO Patent # US-D918374-S) is engineered from injection-molded high-density polyethylene (HDPE), a tough weather-resistant material valued for its thermal stability, UV protection and low moisture absorption properties. SoffitFlow is the perfect soffit vent for humid or coastal areas to aid in safeguarding the home against soffit moisture-related issues.

Advanced design features make SoffitFlow the choice for efficient soffit venting:

4-Inch Diameter Collar: The well-thought-out position of the 4-inch diameter collar is strategically placed towards the back of the SoffitFlow housing, and coupled with the precise engineering of a tapered bottom panel, the two work together harmoniously to maximize the airflow and keep it moving in one direction.

Weep Hole: A weep hole is in place to remove any water accumulation that forms as a result of condensation. It exits in the form of a drip.

Angled Damper: The integrated gravity-assisted damper is angled for optimal airflow. Minimum bathroom fan exhaust requirements to open the damper is 50 CFM. Common bathroom fans on the market vary between 50-110 CFM. The angled damper closes in the absence of airflow from the fan. This aids in preventing backdrafting into the ductwork.

Nose: It’s important to note that SoffitFlow’s nose extends beyond the roofline's fascia. The purpose of this design is to expel the exhaust in an outward direction, helping to prevent the deflection of moisture back into the attic space.

Hinged Grill: The front hinged grill, also removable, is designed to keep wildlife and pests out of the ductwork. The hinged grill easily opens to make cleaning and maintenance a breeze.

HDPE Construction: SoffitFlow’s high-density polyethylene (HDPE) material is durable, standing up to prolonged exposure to sunlight without becoming brittle. This UV resistance ensures that the material retains its strength and appearance over time, making it an ideal choice for both residential and commercial applications.

Durable Finish: SoffitFlow’s durable finish is easy to clean and is unaffected by most industrial chemicals. Its finish is resistant to strong oxidants, acid, alkaline salts and organic solvents.

To simplify installation, SoffitFlow’s packaging doubles as a template. SoffitFlow is compatible with standard 4-inch ducting, making it a versatile solution for both new construction and retrofit projects. SoffitFlow maintains the home's exterior aesthetics with a low-profile design and clean lines.
