nnnnConstruction and working characteristics
nnnnThe modular air service units groups size 2, as the ones of size 1, allow a wide selection of
nnnncombinations.
nnnnThe threaded connections are machined directly on the valve body made with light alloy, so that
nnnneach components can be used individually.
nnnnThey can be wall mounted with head-guard screws masked by covers.
nnnnThe bowls are made of transparent technopolymer, always supplied with shock resistant
nnnntechnopolymer protection, allowing the moisture and oil level control from any angle.
nnnnThe filter can be equipped with manual or semiautomatic water drain valve; furthermore it's
nnnnpossible to install the automatic draining device inside the bowl.
nnnnThe pressure regulator handle is lockable in the desired position.
nnnnThe lubricator oil flow is adjustable with proper handle and it is visibly checked through the sight
nnnndome.
nnnnThe shut-off valve can be equipped with pad-lock to prevent accidents or damages due to
nnnnunauthorized operation.
nnnnThe progressive start-up valve, pneumatically or electropneumatically controlled, allows air
nnnnsupply to the circuit progressively and with adjustable time.
nnnnSome accessories like the wall fixing bracket, pressure gauges with different scales and
nnnndiameters, air intake block that assembled between the elements allows to get in the system
nnnnfiltered or filtered non-lubricated air, are completing the range.
nnnnInstruction for installation and operation
nnnnPay attention to install a group or a single component with air flow direction according to the
nnnnarrows and to the following sequence: filter, pressure regulator, lubricator and with bowls
nnnndownwards. It's possible to fix the group to the wall by removing the covers, which can be installed
nnnnagain for covering the screw after fixing.
nnnnDo not exceed the recommended torque while assembling the connectors.
nnnnDo not exceed the recommended air pressure and temperature limits.
nnnnThe moisture should not exceed the level marked on the bowl and it can be drawn off and carried
nnnnaway by a flexible tube of 0 6/4 directly connected to the discharge valve handle.
nnnnThe pressure should be set from minimum to maximum, rotating the adjusting handle clockwise.
nnnnAs lubricant, we suggest to use oil class FD22 or HG32. Verify that the lubricator is not fed with a
nnnnflow lower than the minimum operational.
nnnnTo set the oil flow rotate the proper adjusting handle in order to get one drop of oil every 300-600
nnnnliters of air.
nnnnThe oil flow will be kept automatically and proportionally to the air flow.
nnnnThe oil can be refilled by mean of proper plug or directly into the bowl after having de-pressurized
nnnnthe system. Do not exceed the maximum level indicated on the bowl.
nnnnFor opening the shut-off valve push and rotate clockwise the operating handle. For closing it and
nnnnconsequently discharging the down stream line, rotate the handle counter-clockwise.
