RETROTEC FlowBox: Extraction Flow Meter and Pressure Pan
RETROTEC FlowBox is a passive exhaust airflow meter designed to work with a digital manometer and measure the airflow of bathroom exhaust fans, range hoods, return air ducts, and residential ventilation systems.
It uses the same range of plugs as the DucTester and the Model 5000/6000 Blower Door units. With all the plugs installed, the FlowBox becomes a pressure pan that does not require tape to locate leaks when used with a Blower Door.
Its 16.5″ × 16.5″ opening allows it to cover large range hoods, even those with built-in lighting, and its reinforced plastic body is designed for daily use on construction sites.
Key Features of the RETROTEC FlowBox
- Dual function: Extraction flow meter and beltless pressure pan in a single unit.
- Large capture area: Dimensions of 16.5″ × 16.5″ × 8″ to cover large range hoods, even those with a light fixture.
- RETROTEC Series Plugs: Same plug system as the DucTester and Blower Door 5000/6000.
- Five measurement ranges: Range 74 and 1, 2, 3, or 4 open orifices, with a flow rate table from 1 to 10 Pa.
- Sturdy construction: Extra-durable plastic for everyday use.

- Flow Measurement for Bathroom Exhaust Fans and Range Hoods
- Verification of Return Air and Mechanical Ventilation in Homes
