Mistral 300
membrane air pump
aquarium membrane air pump with a maximum capacity of 380 l/h(95 gph) (Mistral
300) or 300 l (80 gph), (Mistral 200)
In purchasing this unit you have selected a top quality product. It has been specifically
designed for aquarium use and has been tested by experts. This unit will efficiently meet the
air supply requirements of most types of aquarium.

1. Features
The Mistral membrane air pumps are designed for universal use. At the Mistral 300, the air
delivery capacity can be adjusted over a wide range so it meets the exact requirements of the
equipment being supplied. This is undertaken with a slide control, which adjusts the magnetic
circuit and not the air pressure. The Mistral 200 has a fix output. The housing is made from
cast aluminium and this, combined with the magnetic control system and the vibration
reducing rubber feet, results in exceptionally quiet operation.
IMPORTANT NOTE:
The pump must only be operated at the correct voltage (see type label)

3.Connections
The pump is connected to the equipment it supplies with aquarium air line (1/4”, 4/6 mm). If
ozone is to be used, ozone resistant tubing (e.g. silicone) must be used after the ozoniser.
4. Installation
The pump should be positioned in a dry place. Care should be taken to ensure that water
cannot enter the pump when, for instance, it is switched off for aquarium maintenance or
during a power failure. There are two methods of installation:
-above the water level – see fig. A below
-below the water level. In this case a reliable non-return valve must be fitted in the air line.
– see fig. B below
Ensure that the power plug can be easily reached at all times.

Security advise:
The pump is constructed for indoor use only. Before working at the pump, the power plus
has to be removed. The connection cable and the power plug may not be changed. If the
p
ower cable is damaged, the pump may not be used any more.

5. Maintenance/Cleaning
The pump is constructed for long-term low maintenance operation. The only item requiring
regular attention is the air filter. The air filter is positioned at the top of the pump. This cotton
filter has to be changed at regular intervals dependant on the quality of the ambient air. To
change the filter, undo the securing screw, remove the plastic cap, remove the contaminated
filter pad, fit a genuine replacement and replace the cap, finally
replacing the securing screw.
In case of a decrease in air capacity that is not remedied by replacing the air filter it will be
necessary to replace the membrane and the steel spring inside the pump. These spares are
available from your approved GmbH retailer.
