Detailed Safety Instructions
Warning
1.Perform regular maintenance and inspection of the hollow fiber membrane of MFU filter. Clogging of the hollow fibre membrane may result in poor performance or trouble. Replace the product with a new one after one year of use or when the pressure loss becomes 0.1MPa or more.
2.Do not use or store it outdoors or in direct sunlight. Direct sunlight and ultraviolet rays may deteriorate the hollow fiber membrane and potting agent, which may significantly reduce the filter performance.
3.The explosion-proof function of this product is to prevent splashing when the filter case is damaged, not to prevent the filter case from being damaged itself.
4.Do not use in the following fluids or operating atmospheres Corrosive gases, organic solvents, chemicals, water (steam), excessive humidity, dust, air or nitrogen containing oil mist, etc.
Caution
1.Be sure to flush the inside of the pipe with clean air before piping. Dust, rust, sealing tape, etc. in the piping may cause clogging. Also, when connecting pipes, etc., be sure to flush from the air inflow direction with clean air in order to reduce the effect of dust emission from the connection.
2.The filter element of this product cannot be replaced.
3.Depending on the usage conditions, the hollow fibers may be disordered, but this will not affect the performance.
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.
