Supply air
1. For the compressed air quality, refer to 2.4.3, 2.5.3 and 2.6.3 of ISO8573-1:2001 (JIS
B8392-1:2003).
2. It is recommended that an air filter and a mist separator are connected to the upstream side of
the ejector and the pump system. (Refer to Air Preparation Equipment Selection Guide in Best
Pneumatics 5 for detail.)
3. Using compressed air which contains chemicals, synthetic oils containing organic solvents,
salts or corrosive gases, etc. can cause damage or malfunction. Do not use compressed air
containing toxic impurities.
4. If the compressed air contains excessive moisture or carbon powder, it can stick to the vacuum
parts (the nozzle diffuser), inside of the solenoid valve or the pressure switch and cause a
decrease in performance or operation failure. An air dryer, mist separator, and filter should be
installed upstream from filters.
If condensation in the drain bowl and air filter is not emptied on a regular basis, the bowl will
overflow and allow the condensation to enter the compressed air lines. This causes malfunction
of pneumatic equipment. If the drain bowl is difficult to check and remove, installation of a drain
bowl with an auto drain option is recommended.
5. Use the product within the specified supply pressure range (0.2 to 0.5 MPa). Operation over the
specified supply pressure range can cause damage to the product.
