9. Piping Size/Diffuser
If it is expected that the secondary air flow velocity will be more than 30 m/s (100
ft/s), install a diffuser in order to keep the flow velocity below 30 m/s (100 ft/s).
If the distance between the product and the air-using equipment is great, a possible
drop in pressure should be taken into consideration when selecting the piping size. In
addition, when installing the strainer, the strainer screen should be either at the 3
o’clock or 9 o’clock position to prevent condensate accumulation.

10. Two-stage Pressure Reduction
Two-stage pressure reduction should be performed whenever the pressure
cannot be reduced to the desired level with the product due to operating range
limitations, such as when the reduction ratio is greater than 10:1.
