2. Installation and Handling

2-1. Air supply

① The air supplied to the lock unit should be filtered by SMC AF series air filter and regulated to the specified
set pressure by SMC AR series regulator.

・Type of fluids
Please contact SMC when using the product in applications other than with compressed air.
・When there is a large amount of condensate
Compressed air containing a large amount of condensate can cause the malfunction of pneumatic
equipment. An air dryer or water droplet separator should be installed upstream from the filters.
・Drain flushing
If condensate in the drain bowl is not emptied on a regular basis, the bowl will overflow and this may cause
the 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.
・Use clean air.
Do not use compressed air which contains chemicals, synthetic oils containing organic solvents, salts or
corrosive gases, etc., as this can cause damage or a malfunction.

・When extremely dry air is used as the fluid, degradation of the lubrication properties inside the
equipment may occur, resulting in reduced reliability (or reduced service life) of the equipment.
Please consult with SMC.
・Install an air filter.
Install an air filter upstream near the valve. Select an air filter with a filtration size of 5μm or smaller.
・Therefore, take appropriate measures to ensure air quality, by providing an after cooler, or water
separator, if needed.
Compressed air that contains excessive foreign material may cause malfunction of valves and other
pneumatic equipment. Therefore, take appropriate measures to ensure air quality, such as by providing an
after cooler, air dryer, or water separator.
・Ensure that the fluid temperature and ambient temperature are within the specified range.
When operating at temperatures below 5
seals or a malfunction. Corrective measures should be taken to prevent freezing.
② Lubrication of lock unit
The product has been lubricated during manufacturing, so it does not require lubrication in service.
Regular or continuous application of oil to the lock unit may reduce locking force.
For detailed information regarding the quality of the compressed air described above, refer to SMC's
"Air Cleaning Systems".
