Required inlet air flow rate = required outlet air flow rate + purge air flow rate
The air supply capacity must be at least equal to the required inlet air flow rate or required outlet air flow rate and dehumidification capacity cannot be obtained.
The air used to discharge moisture from the inside of the hollow fiber membrane is called purge air.
			

For the following conditions in accordance with [Test condition: ISO 12500-4:2009 compliant] in addition to the conditions above.
・Water droplet on the filter inlet side=33g/m³
（Water droplet indicates condensed moisture. Water vapor which is not condensed is not included.）
・Inlet temperature=25℃
・When the air flow capacity, inlet pressure, and the amount of water droplets on the filter inlet side are stable.
・When a new element is used.
			

For the following conditions in accordance with [Measurement: ISO 8573-4:2001, Test method ISO 12500-3:2009 compliant] in addition to the conditions above.
・When the air flow capacity, inlet pressure, and the amount of solid or liquid particles on the filter inlet side are stable.
・When a new element is used.
			

For the following conditions in accordance with [Measurement: ISO 8573-4:2001, Test method ISO 12500-3:2009 compliant] in addition to the conditions above.
・Oil mist concentration on the filter inlet side = 10 mg/m³.
・When the air flow capacity, inlet pressure, and the oil mist concentration on the filter inlet side are stable.
・When a new element is used.

The bowl seal and other O-rings are slightly lubricated.

The odor derived from oil vapor contained in compressed air. The activated carbon filter adsorbs and removes , but it does not remove all odor.
			

The length between the connection ports of the system refers to the length between the connection ports of the modular connection.

The ratio of the outlet air flow rate to the maximum flow capacity.

If it is less than 100%, it can be used, so please use this as a reference to determine how much margin to leave.

Required inlet air flow rate = required outlet air flow rate + purge air flow rate
The air supply capacity must be at least equal to the required inlet air flow rate or required outlet air flow rate and dehumidification capacity cannot be obtained.
The air used to discharge moisture from the inside of the hollow fiber membrane is called purge air.
			

This is the corrected flow rate when the inlet air pressure and temperature have a significant effect on the outlet dry air flow rate, which differs from the conditions in the Standard Performance column.
The higher the inlet air pressure and the lower the inlet air pressure dew point, the lower the corrected outlet air flow and outlet air pressure dew point.


Corrected outlet air flow rate Q‘=Outlet air flow rate Q÷(Correction factorⒶ×Ⓑ)

The atmospheric pressure dew point is the temperature at which condensation begins to occur when air is cooled under atmospheric pressure.
The outlet air pressure dew point obtained depends on the inlet air pressure, inlet air dew point, and outlet air flow rate.
			

The pressure dew point is the temperature at which condensation starts to occur when compressed air is cooled under a certain pressure.
The outlet air pressure dew point obtained depends on the inlet air pressure,   inlet air dew point, and outlet air flow rate.
			

Indicates purity class of inlet compressed air.
Be sure to supply compressed air that meets the selected purity class.
If the product is supplied with compressed air that does not meet the selected inlet side purity class, the performance of the product will be compromised, and the outlet side compressed air will not meet the selected purity class.

The compressed air purity class is indicated based on ISO 8573-1:2010(JIS B 8392-1:2012)
Designation example[6:8:4]
　6: Particle class  Mass concentration  Cp 0<Cp≦5　[mg/m³] 
　8: Humidity and liquid water class  Concentration of liquid water Cw  0.5<Cw≦5　[g/m&³] 
　4: Oil class  Concentration of total oil  ≦5　[mg/m³] 

Indicates purity class of outlet compressed air.
Select the required outlet side compressed air purity class.

The compressed air purity class is indicated based on ISO 8573-1:2010(JIS B 8392-1:2012)
Designation example[1:5:1]
　1: Particles class  Maximum number of particles per cubic meter as a function of particle size d [μm]
　　・0.1<d≦0.5　　　　　≦20000 
　　・0.5<d≦1.0　　　　　≦400 
　　・1.0<d≦5.0　　　　　≦10
