Detailed Safety Instructions
Caution
1.Be sure to adjust the regulator in the direction of increasing pressure, and be sure to push the handle to lock it after adjusting the pressure.
2.Until the supply pressure rises to 0.05MPa for manual drain type and 0.15MPa for auto drain type, air will be discharged from the drain outlet, but this is not a malfunction.. At this timing, turning the drain knob will not stop the air flow. (If it takes a long time for the supply pressure to rise to 0.15MPa, please consult with PISCO.)
3.The drainage knob must be operated with the fingertips.
4.Use nylon tubing with an internal diameter of ø6 mm when piping tubing to the joint of the manual drain cock. The tube should not be bent immediately after the fitting.
5.The joint of the manual drain cock rotates freely and there is no need to remove the tube when draining manually.
6.Refer to the corresponding pages of precautions related to the dual-display digital pressure sensor and digital pressure gauge in the digital catalog.
Frequently Asked Questions for Air Preparation Series
Fiber Dryer can dehumidify inert gases such as oxygen except for pure oxygen, nitrogen, helium, and argon.
However, since our Fiber Dryer release a part of the fluid medium to the atmosphere as purge air, the discharged gas fills the space surrounding the dryer and at worst, it can cause an accident. To prevent the risk, straight type dryer (DMB type) or flexible type dryer (DMF type) shall be used, and supply compressed air to the purge air port from a different circuit.
Besides, the push-in fitting connected to Fiber Dryer may leak gas depending on circumstances. Taking these points into consideration, decide to use or not to use the product by user's responsibility.
The dehumidification principle by hollow fiber film of Fiber Dry is like this; when flowing compressed air in the filter, only moisture go through the membrane to outside, then dry air comes out from the exit.
Some part of the dry air is diverted as purge air. The purge air removes
water-vapor inside the hollow fiber filter and inner casing by sweeping
over the outer surface of the filter and carrying vapor to the outside.
Thus hollow fiber filter is kept at low steam concentration which allows it
to dehumidify continuously.
Fiber Dryer has the function of purge air flow-control, and it can control
the dryness of available dry air.
The much the purge flow is (=The higher the percentage of purge is),
the higher the dryness.
▼【Video】 The dehumidification principle of Fiber Dryer
The dew point means the temperature which the moisture in gas (air, gas) becomes water drops. We can call it "dew-point temperature" as well. It is used to indicate the amount of moisture in gas because dew-point temperature changes according to the amount of moisture in gas.
The lower the dew-point temperature is, the less the moisture is (= it means dry), and the higher the dew-point temperature is, the more the moisture is (it means humid).
Besides, the higher the gas pressure is, the higher the dew-point temperature becomes. Compressed air contains much amount of moisture (drain). If it is used as it is, it causes corrosion of pneumatic equipment such as cylinders or solenoid valves. Therefore, drying compressed air is necessary.
