Subject to EAR. ECCN EAR99 and related export control restrictions.
Actual air throughput = 75 x 1.07 x 0.93 x 0.65 x 1.25 = 61 scfm (104 m³/h)
61 scfm (104 m³/h) is the maximum flow rate of the dryer under the aforementioned operating conditions.
Selection of the best suitable model in accordance with the operating conditions:
Air throughput acc. to planning =
Requ. air throughput
Factor (F1) x Factor (F2) x Factor (F3) x Factor (F4)
Example:
The following operating parameters are known:
 Required air mass = 100 scfm (170 m
3
/h)
 Air inlet pressure = 120 psig (8 barg)
 Ambient temperature = 105°F (40°C)
 Air inlet temperature = 122°F (50°C)
 Pressure dew point = 50°F (10°C)

  Factor (F1) = 1.07
  Factor (F2) = 0.93
  Factor (F3) = 0.65
  Factor (F4) = 1.25
To find out the correct dryer version, the required air mass must be divided by the correction factors of the parameters
indicated above:
Air throughput acc. to planning =
100
= 124 scfm (211 m³/h)
1.07 x 0.93 x 0.65 x 1.25
The suitable model for these requirements is SR 125 (with a spec. nominal capacity of
125 scfm [212 m³/h]).
8.5 Connection to the compressed-air system
Danger!
Compressed air!
All works must only be carried out by qualified skilled personnel.
Never work on compressed-air systems which are under pressure.
The operator or the user must ensure that the dryer is never operated with a pressure exceeding the
maximum pressure value indicated on the name plate.
Exceeding the maximum operating pressure can be dangerous for the operator but also for the device.
The air temperature and the air flow at the inlet of the dryer must lie within the limit values indicated on the name
plate. The connecting lines must be free from dust, iron rust, shards and other contaminations and correspond to the
flow rate of the dryer. Should air with a very high temperature be treated, the installation of an aftercooler may be
necessary. For the implementation of maintenance works, the installation of a bypass system is recommended.
The dryer was designed in such a manner that vibrations that may occur during operation are limited. Therefore, it is
advisable to employ connecting lines (flexible hoses, vibration-inhibiting fittings etc.) which protect the dryer against
possible vibrations in the pipework.
