상품 소개

This self-contained tester connects to an isolated duct section, raises or lowers it to a defined pressure and measures the airflow required to hold that condition. A variable-speed blower, calibrated inlet and dual pressure channels allow the controller to calculate leakage rate during positive or negative tests. The wheeled enclosure and flexible test hose support field commissioning across large installations.

주요 기능

Reversible blower supports positive and negative duct tests.

Closed-loop control maintains the selected test pressure.

Calibrated inlet measurement quantifies stabilizing leakage airflow.

Dual pressure channels monitor duct pressure and flow element.

Guided controller calculates leakage rate and test duration.

Wheeled field enclosure organizes hose, cables and adapters.

고객 제품 관심사

Duct leakage must be quantified at a stable specified pressure even though the system response changes with seal quality, section size and test direction.

Test pressure drifts as leakage changes during the run.Closed-loop blower control continuously adjusts flow to maintain the selected pressure.

One-direction equipment cannot assess both supply and extract ductwork.A reversible flow arrangement supports positive and negative pressure tests.

Leakage calculations vary when technicians use separate instruments.Integrated pressure and calibrated-flow channels calculate leakage within one guided workflow.

Large test equipment is difficult to move through an active site.A compact wheeled enclosure and stored flexible hose simplify relocation between duct sections.
