Marking of Products
The noise from an air motor consists of both mechanical noise and a
pulsating noise from the air flowing out of the outlet. The installation
of the motor has a considerable effect on mechanical noise. It should
be installed so that no mechanical resonance effects occur. The
outlet air creates a noise level which can amount to 108 dB(A) if the
air is allowed to exhaust freely into the atmosphere. To reduce noise
levels, various types of outlet silencer are used. The most common
type screws directly into the outlet port of the motor. A wide range of
silencers are available. Many are made of sintered brass or sintered
plastic. Since the motor function causes the exhaust air to pulsate, it
is a good idea to allow the air to exhaust into some kind of chamber
first, which reduces the pulsations before they reach the silencer. The
best silencing method is to connect a soft hose to a central silencer
allowing the speed of the air to reduce as much as possible.
NOTE! Remember that if a silencer is too small or is blocked, back
pressure is generated on the outlet side of the motor, which in turn
reduces the motor power.
Sound Levels
Sound levels are measured at free speed with the measuring
instrument positioned 1 m away from the air motor, see the table
below.

Compressed Air Quality
Oil and oil mist are avoided whenever possible to ensure a clean work
environment. In addition, purchasing, installation and maintenance of
oil mist equipment can be expensive. All users in all industries now try
to avoid using components which have to be lubricated.
The P1V-S motor is equipped with vanes for intermittent lubrication
free operation as standard, which is the most common application of
air motors. The motor is also available with optional hard vanes for
continuous lubrication-free operation (option “C”).
The P1V-S motor is equipped as standard with food grade grease in
the planetary gearbox. An oil which is approved by the food industry is
also available if supplementary lubrication is required.

Dry Unlubricated Compressed Air
If unlubricated compressed air is used, the compressed air should
comply with the purity standards below in order to guarantee the
longest possible overall service life. If the unlubricated compressed
air has a high water content, condensation forms inside the motor,
causing corrosion in all internal components. A ballbearing can be
destroyed in a remarkably short time if it comes into contact with a
single water droplet.
For indoor use, we recommend ISO8573-1 purity class 3.4.1. To
achieve this, compressors must be fitted with aftercoolers, oil filters,
refrigerant air dryers and air filters.
For indoor / outdoor use, we recommend ISO8573-1 purity class
1.2.1. To achieve this, compressors must be fitted with aftercoolers,
oil filters, adsorption dryers and dust filters.
Oil Mist
If oil mist is used (approx. 1 drop of oil per m³ of compressed air), the
oil not only acts as a lubricant but also protects against corrosion.
This means that compressed air with a certain water content may be
used without causing corrosion problems inside the motor.
ISO8573-1 purity class 3.-.5 may be used without difficulty.
The following oils are recommended for use in the foodstuffs
industry: Shell Cassida Fluid HF 32 or Klüberoil 4 UH 1-32

For example: compressed air to purity class 3.4.3
This means a 5 µm filter (standard filter), dew point +3 ºC (refrigerant
cooled) and an oil concentration of 1,0 mg oil/m³ (as supplied by a
standard compressor with a standard filter).
