Air connection
Screw the air hose into the air intake on the booster. For best efficiency, use the same hose
diameter as the internal diameter of the connection on the air intake.
1.8.1.
Air treatment system
The air valve is constructed for oil-free air. Lubrication of the air is not allowed. However, if the
air is very dry (laboratory air), the air may be lubricated with water. As prevention purpose, a
filtration of the air by means of a 5 micron filter or finer is recommended. Recommended air
quality according to PN-ISO8573-1:2010 is particles class 6, water class 4 and oil class 4. Dirt in
the air can under unfortunate circumstances be the cause of a breakdown. If a compressor used
to generate compressed air is not fitted with an air dryer it is recommended to use a water
separator to remove the extent of water from the prepared air.
To facilitate the operation of the pump we recommend an air treatment system connected to
the air supply. These components should be included:
1) Regulator to adjust the air pressure;
2) Manometer to read the actual pressure;
3) Needle valve to adjust the air flow (especially when operating the pump in the lower range
of performance); It is recommended to install the needle valve between the booster and pump
4) Filter.
These components are included in Tapflo’s Air treatment system which can be ordered from
us.
1.8.2.
Pressure ratio 2:1
The pressure booster has the function to transmit the primary pressure (from air supply) to an
output pressure of up to twice as much. The pressure ratio between the input and output side
is, by default, set to 2:1.

Example of installation
NOTE! Do not exceed 0,7 bar suction pressure! Higher pressure may cause premature
diaphragm failure and irregular pump operation.
