If there is possibility of freezing at the air exhaust, it is good to pre-heat the air before it
reaches the air intake in order to raise the dew point of the air.
NOTE! Make sure that the air temperature does not exceed 50°C (122°F).
If icing / freezing is still a problem with the standard muffler, we recommend using our
heavy duty metal muffler. Contact us for more information.

Booster operation conditions
In principal the booster is designed for intermittent operation. It cannot be used as a
replacement for a compressor. During continuous work the lifetime is significantly
decreased due to overheating of the device and increased wear of the seals.
In order to obtain optimal lifetime it is advised that the discharging frequency be
not higher than 0,33 Hz (once pressure discharge per 3 seconds). The exact rest
periods cannot be determined generally because they depend on the discharge
frequency and heat removal conditions.
It is recommended that for every hour of booster operation at least a 5 minute rest
period is foreseen. If these conditions are difficult or impossible to fulfil, it is
recommended to use an air reservoir in the installation.
To increase the booster lifetime a bypass installation can be used in order to relieve
the booster at lower pressures when the filter press is not yet filled.
Maximum temperature of air supplier to the booster cannot be higher than 25
º
C.
Recommend air quality is 6:4:4 according to PN-ISO8573-1:2010.

Pump stopping
The pump can be stopped in two ways:
1)
By closing of the discharge valve. The pressure from the system will stop the pump
automatically. The pump restarts easily when the valve is opened again.
NOTE! When using this method keep in mind that air must be supplied to the pump.
This is essential to keep the diaphragms in balance what protects them from premature
failure.
2)
By cutting off the air supply.
NOTE! When using this method make sure that the discharge valve is opened to relief
the pumps pressure.
