Diaphragm Blowers EL-S single system

The operating principle of an electromagnetic oscillation is well known for its excellent efficiency! The electrical energy is not used up by mechanical friction in crank assemblies, sliding parts or bearings, but is directly utilized for pump movement via the membranes. Lubricants are not necessary and are not to be found either in the linear drive or in the pump chamber. This means absolute oil-free operation.

Integrated overload protection
The EL series are supplied with a thermal overload protection. The contact breaks when the temperature of the windings reaches hazard value of the probe at 130°C. After the coil has cooled down below 120°C, the blowers starts again automatically.

Protective switch (auto stopper)
The EL series is supplied with a protection switch, in case of a diaphragm break. It consists of a micro switch which turns off the blower. Due to the fact, the blower is protected against deviation.

Fault alarm lamp
The EL series may optional is provided with a fault alarm lamp. These air pumps will indicate any diaphragm fault of the linear motor with a signal lamp, placed on the outside cover of the air pump.

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.

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 in 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 air flow.

Pulsation-free air flow
Specially formed pump chambers and the muffler integrated in the tank base provide an air flow, which is practically pulsation-free.

Weatherproof
The SLL and EL series are rainproof and weatherproof. However, they should not be exposed to direct sunlight, rain or snow.

Universal service kits
For each model series service kits are available. They are vacuum-packed in aluminium foil for better and longer life/ storage.
