a-series configurations: equipment resistance 1800 Pa; screen pitch 5–9°. Match aspiration to the selected model and grain duty.
Shared values: equipment resistance 1800 Pa; amplitude 3–5 mm; vibration speed 15.65 s⁻¹.
Select the model by material, throughput and installation requirements.
Start with the duty in your flow sheet
Compare capacity and aspiration volume together. A model choice also needs the available fan duty, duct layout and grain condition.

Questions about the TQSF
What warranty do I get?
1 year on the machine. Wear parts, including roll surfaces, belts, scrapers, brushes, screens and filter bags, are excluded.
What information is needed to choose a model?
Compare capacity and aspiration volume together. A model choice also needs the available fan duty, duct layout and grain condition.
Can it replace my existing machine?
Send the nameplate, photographs and layout.
Where do the specifications come from?

Screen access and installation connections
Aspiration and installation
The installed configuration shows the flexible aspiration connection above the screen hood and the vibration drive below. These connections need clearance when planning access and duct routing.
Observe the screening area
The transparent hood panels provide a view of the screen surface without opening the enclosure. The close view shows the screen and feed distribution area behind the windows.
Separate discharge connections
Separate chutes and a divided collecting box keep the discharge paths apart. Match the downstream pipe positions to the selected configuration.
