Data coverage
Brochures linked from the product pages (pages via Firecrawl; brochures direct from the platform's asset host): multistage centrifugal frames (maximum flow, pressure and vacuum, each kept in m³/h, bar and mmHg only where the cfm / psig / inHg twin agrees), REVOLUTIONPLUS turbo (air flow per outlet pressure, weight), HRA air suspension turbo (motor power, airflow per discharge pressure) and Defender Plus rotary lobe packages (capacity, motor and noise at maximum pressure and vacuum)
– Multistage minimum flows and stage counts not read; maxima whose two units disagree are left out (e.g. Lamson 2000 flow, 950 frame pressure)
– Defender Plus: DF LOBE+ 86 is printed twice with different figures; left out
– Defender lobe and screw packages (2021 brochures) list rows by frame size without model names; not read
– TurboTron regenerative, MultiFlow, T-Series and TS/PS exhausters publish only maxima ("to 400 CFM"); performance grids per speed not read
– Legacy central vacuum systems (T-Vac, portable) give horsepower and dimensions only
