Everything a professional piston compressor should be

You might think that all a compressor has to do is to supply quality air every time it is switched on. A great compressor does more. That is why we built the belt-driven aluminium pistons to deliver on safety, reliability, ease of use and flexibility. The models in our range of aluminium piston compressors are all designed with mobility and user-friendliness in mind. Thanks to its all-in-one build, these series offer a compact footprint and outstanding set-up flexibility. Lightweight and compact, the smaller models have a full handle grip so you can effortlessly move your Automan to where you need it. The belt-driven aluminium range contains AC and AB series, from 2 up to 20 HP. On the larger models, we also supply aftercoolers and an automotive-derived dry paper air filter to deliver clean air according to your needs. The belt-drive range is extended with diesel and petrol versions which are designed for applications where no or not enough voltage supply is within reach. The petrol and diesel series ranges from 4 to 11 HP offering the best solution for your operations.

AC series

The AC series oil-lubricated piston compressors are designed with a slow-running compressor block for long service life. This feature also ensures a low noise level, which makes for a more pleasant working environment. Cast iron cylinders with low-speed pistons have traditionally been recognized for their durability.

You can select the compressor that best fits your air requirements. Ranging from 2 HP to 20 HP, you can choose from a selection of air receivers – 27, 50, 90, 200, 270 or 500 liters horizontal receiver and 150 or 270 liters vertical receiver as a space saving option.

AB series

The AB oil-lubricated series of belt-drive pistons is designed with high quality components to guarantee trouble-free operations. Thanks to its all-in-one build, the AB series guarantee a compact footprint and excellent set-up flexibility.The built-in, adjustable pressure differential switch allows the compressor to run automatically and maintain a minimum set pressure in the air receiver, giving peace of mind to the operator.

Ranging from 2 HP to 10 HP, its dual purpose belt guard does not only offer protection for the belt, but also directs cool air over the complete block. This means superior cooling in high ambient conditions.
