Purge flow rates for these products are determined by sample gas inlet pressure, as shown in the table above.
(Purge flow rates may vary according to sample gas inlet temperature and ambient temperature around the dryer.)
Please contact us for more information about purge flow rates when pressure isn't specified.
We can adjust the circuit to enable you to obtain the desired purge flow rate at your specified pressure. Please contact us for more information.

Operating instructions

  • The product is designed for indoor use. Please install the product at a place where the product is not subjected to direct sunlight, rainwater, high temperature radiation heat.
  • Excessive pressure should not be applied to the purge gas inlet and outlet (max. 0.05 MPa (Gauge)) (max.7.1 psig).
  • To remove drainage, dust, etc., we recommend installing a filter (pore size 5 μm) and an automatic drain system at the supply gas inlet. Dehumidification efficiency may decrease if drainage is mixed into the supply gas.
  • When using a lubricated compressor , we recommend installing an automatic oil mist separator at the supply gas inlet side with filtration of <0.3 μm, 95% particle size collection rate, and oil-mist concentration of <1 mgf/Nm3.
  • The supply gas should be clean and free of dust, corrosive gases, organic solvents, chemicals, and similar substances.
  • For operation with a small amount of purge gas, (less than 10 / min(ANR) (0.35 scfm)), we recommend installing a small-aperture fixed orifice rather than a needle valve.
    “ANR” refers to air with a temperature of 20°C, an absolute pressure of 101.3 kPa (760mmHg), and a relative humidity of 65%.
  • When installing a pressure-reducing valve, we recommend installing the valve at the outlet side of the dryer to improve dehumidification efficiency.
  • The dry air dew point varies according to the supply air flow rate, pressure, temperature, moisture content, purge air (gas) ratio, ambient temperature, and other operating conditions. In particular, if the supply air (gas) temperature is high, the dew point of the dry air will rise. We recommend to set the supply air (gas) temperature as low as possible.
