A high quality Japanese air pump, very quiet and has a long life!

Oil-free pump, operates on a piston instead of a rubber membrane.

This is the absolute reference to the air pumps, because there is no membrane in the pump will not fall out as with other pumps may be the case. The Nitto has his life due to the high technology. Do you want the best for your pond filter and fish do not skimp and buy this topper.

Max 120 liters / minute at 0.18 bar
Power consumption: 130 W
Suitable for continuous load

General guidelines for air pumps:
The location of the air pump may be both above and below the water level are. If the pump is below the water level
is placed, a non-return valve should be used. This is to "full" to prevent the pump from running.
Place the pump never in a hot environment. This in order to prevent drying out of the membranes. If the
pump in a room is too warm, the engine can not be sufficiently cooled so that the pump before
needs to be replaced.

The pump will run hot if it is not enough pressure can be lost, this can have various causes. inter alia
air stones placed too deep, too small or too little air stones. Warming up of the pump can result in
that the membranes rupture or the electrical part burned.

We recommend the following minimum number of stones to use:

Pump 20ltr. / Min 6 stones Ø 5cm.
Pump 40ltr. / Min 10 stones Ø 5cm.
Pump 60ltr. / Min 15 stones Ø 5cm.

Always try to use an air duct with the largest possible diameter. Most pumps have
18mm. connection. By 18mm. direction as far as possible and continue as late as possible
to branch to 4mm. the pressure on the hose is substantially less pump.
