- 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 these take in air from the surrounding area and direct it into the pond
In winter, this could mean that you cool down your pond without meaning to.
- They should also be positioned above the waterline if possible; if this is not the case, please use non-return valves. If water enters the pump, this is not covered by the warranty.
- The designation normally indicates the litres of air per minute that the pump displaces. In this regard, sufficient and/or suitable air diffusers must also be used .
- We recommend 9 mm or 16 mm air hose to ensure that the pump works efficiently
(from 80 litres/minute, a 16 mm air hose can already be used).

A Dong Yang 20 generates 20 litres of air per minute. Diffusers that allow 20 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 air diffusers are selected,
- if the air outlets are not cleaned and become clogged over time,
- air regulation via an air valve,
- 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:
- 2 x Angel Aqua diffusers 22 x 4 cm (9 mm air hose) - approx. 10-13 l/min output per diffuser
- 2 x aeration rod 30 cm connection 16 mm (16 mm air hose) - approx. 15 l/min outflow per diffuser
