1. Establish the required airflow
Use the aeration process design to identify the air volume needed at the operating point. State whether the figure is per blower or for the complete system, and include the planned operating schedule.

Prepare the duty point and site details before comparing blower models. This guide explains the information needed for a useful technical inquiry.
2. Confirm the required discharge pressure
Provide the water depth, diffuser requirements and estimated piping losses from the process design. A blower should be checked against the total required pressure at the specified flow.
3. Describe site and installation conditions
Share inlet air temperature, altitude, power supply, available space, inlet filtration and noise requirements. These details can affect the final configuration.
4. Compare catalog series
The HTSR and HTSR-Z series list 0.50–226 m³/min and 9.8–98 kPa. The HTSR-S two-stage series lists 6.25–207 m³/min and 98–196 kPa. These are catalog ranges, not guaranteed performance at every combination of flow and pressure.
