Inlet Fans

Positive Pressure Fan (PPF): Belt Drive

Designed to inject fresh air into barns

Product Overview

VES-Artex Positive Pressure (PPF): Belt Drive fans are designed to inject fresh air into barns, parlors, or holding areas. They are also great additions to facilities where negative inlets are not enough. PPF fans help reduce static pressure by forcing air into the barn, providing more air to circulate directly to the herd. Fans feature quick-change belts that are built to last and provide consistent, reliable power.
