Round Dampers

Say goodbye to inconsistent airflow in your multi-zone space with round dampers for VAV and VVT zoning systems. Prolon's PL-AV series offers precise airflow control with its durable galvanized steel construction, single blade design, and Polyolefin insulation seal. Opt for the PL-FSD flow sensor for pressure-independent efficiency, keeping your comfort constant and energy bills low.

Prolon's PL-AV series is agalvanized steel housing, boasting a sleek satin finish and durable 22-gauge construction. A single blade, equipped with a dual-density control damper and Polyolefin insulation seal, ensures smooth, airtight operation. Plus, the 12.5mm shaft seamlessly integrates with most actuators, making installation a breeze.
