- Air pumps must always be protected from the weather.
- It is also important that they are not exposed to excessively high (+40°C) or low (below 5°C) temperatures, as well as humidity (filter shaft/chamber). This leads to rapid wear and tear and even defects
- They should also not be too far away (we recommend max. 2 to 4 metres) from the pond
- Please note that they take in air from the surrounding area and feed it into the pond. In winter, this could mean that you cool down your pond without meaning to.
- If possible, they should also be positioned above the waterline. If this is not the case, please use non-return valves. If water enters the pump, this is not covered by the warranty.
- The label normally indicates the litres of air per minute that the pump discharges. Sufficient and/or suitable air diffusers must also be used in this regard.
- We recommend 9 mm or 16 mm air hose to ensure that the pump works efficiently (from 80 litres/minute, 16 mm air hose can already be used).

A Dong Yang 120 generates 120 litres of air per minute. Diffusers that also allow 120 litres of air per minute to escape should be selected.
Air that does not escape has a wearing effect on the membranes.
Wear occurs, for example
- if the wrong diffusers are selected,
- if the diffusers are not cleaned and become clogged over time,
- air regulation by means of an air tap,
- air hoses that are too small,
- dirty air filters,
- normal wear and tear, etc.
With this air pump, the aerators can be suspended at a water depth of 2 metres.
We recommend the following diffusers:
- 1 x aeration ring Ø60cm (16mm air hose) - approx. 80-92 l/min output per diffuser
- 2 x professional membrane aerator 27 cm connection 16 mm (16 mm air hose) - approx. 10-80 l/min output per aerator
