Long life expectancy
Motor and pump parts are combined in one single construction. The compact and light construction form and the simple mechanism guarantee a long and reliable period of operation.
The high degree of efficiency
The principle of electromagnetic oscillation, which practically has no mechanical friction, minimises power consumption and provides a high degree of efficiency.
Low noise level
The soundproof casing and the muffler integrated into the tank base reduce operating noise.
Low vibration
Motor and pump parts are separated by a vibration-isolating rubber, so only low vibration consists.
Completely oil-free
The oil-free operation guarantees a dry and unadulterated airflow.
Pulsation-free airflow
Specially formed pump chambers and the muffler integrated into the tank base provide an airflow, which is practically pulsation-free.
Weatherproof
The JDK series are rainproof and weatherproof. However, they should not be exposed to direct sunlight, rain, or snow.

Installation Tips
- Ensure that the air pump is receiving a clean, fresh air supply.
- If you have recently had a pump fail check the back pressure on the pump. We can supply pressure gauges so you can do this.
- Ensure your pump is not liable for flooding. It is an electrical device and whilst rainproof, is not waterproof
- Ensure that the tubing pipe diameter is kept as close to the pump outlet as possible. This will reduce any artificial pressure, which may reduce the lifetime between diaphragm changes.
- If using for an aquatic application with small-bore manifolds leave at least one tap fully open, venting into the water, this will help any pressure known to be created by aquatic air stones.
- Clean the filter regularly. Annually as a minimum, more frequent if you suspect ingress of dirt
