Please consult with SMC if you use a fluid other than compressed air.
3.Installation and Handling
3-1.Air source
The compressed air supplied for the cylinder shall be filtered by air filter, SMC’s AF series and
decreased to given set pressure by regulator, SMC’s AR series for use.
Warning
1) 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 malfunction.
Caution
2) Install air filters.
Install air filters close to valves at their upstream side. A filtration degree of 5μm or less should be
selected.
3) Install an aftercooler, air dryer, or water separator (Drain Catch).
Air that includes excessive drainage may cause malfunction of valves and other pneumatic equipment. To
prevent this, install an air dryer, aftercooler or water separator,etc.
4) Use the product within the specified range of fluid and ambient temperature.
Take measures to prevent freezing when below 5℃, since moisture in circuits can freeze and cause
damage to seals and lead to malfunctions.
The allowable operating range for this product is between :
Without auto switch 0 to 70℃
With auto switch 0 to 60℃
If the cylinder is used at temp out of this range, the packing hardens, the grease is lost and the packing is
worn, finally air leaks can result.
For compressed air quality, refer to "Air Preparation Equipment” catalog.
5) Lubrication of cylinder
【Grease for standard(for non-food)】
The cylinder has been lubricated for life at the factory and can be used without any further lubrication.
However, in the event that it is lubricated additionally, be sure to use Class 1 turbine oil (with no additive)
ISO VG32.
Stopping lubrication later may lead to malfunctions because the new lubricant will cancel out the original
lubricant. Therefore, lubrication must be continued once it has been started.
【Grease for food】
The cylinder has been lubricated for life at the factory and can be used without any further lubrication.
If the cylinder is supplied with lubrication, it may fail in operation..
