Direct Drainage Reviews

 The JDK-250C comes with pressure relief valve and a 1m alarm cable, power cable length 1.5m.

The JDK models are a direct replacement of the EL series and feature less energy consumption (up to 30% - depending on the application) and less overall dimensions (also by about 30%) compared to the SLL- and EL-series. This makes the class not only more compactly, but also lighter.

 Secoh Air Blower Service Check List


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.

The SLL, EL and JDK 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.
