AL-KO Power Units 250-350+

Delivering clean air in the workshop

The largest of the AL-KO Power Unit® range, the 250, 300, 350 and 350+ are ideally suited to a heavy workload, with long filter life and powerful but compact units for maximum air flows between 3,500 and 10,000 m3/h, suitable for single or multiple machines.

With a large range of control and waste disposal options, including energy saving frequency-controlled motors, briquette presses, automatic start and shut-off gates, the Power Unit 250 – 350+ can be tailored to meet you exact requirements.

Antistatic polyester needle felt class M filters are kept at maximum efficiency by the  AL-KO OPTI-JET® reverse air jet filter cleaning system.  The large integral air surge tank ensures maximum filter cleaning with a low demand on your compressed air supply.

Like all the AL-KO power unit range, the 250, 300, 350 and 350+ have been fully tested and boast both the GS and H3 marks and are ATEX-certified for use inside the workshop.

High efficiency

In these pure-air industrial extraction systems, the impeller fan is located behind the filter. Extracted air with its dust and chippings is taken through the filter and cleaned before it passes the fan. As the fan only comes into contact with clean air, it can be designed as a high-performance impeller. The fan casing can then operate with very small air slots which, in conjunction with the closed impeller, help the pure-air system to achieve a far higher efficiency than a raw-air system.
