Low rate intermittent slurry aeration is considered to be one of the best ways of keeping slurry in an optimum condition for spreading without the need for extensive mixing with traditional over-the-top mixers and side stirrers which can be very costly in man-hours and diesel.

Low-rate intermittent aeration enables nitrogen to be retained in soluble form within the slurry thus reducing loss of nitrogen as ammonia emissions. If spread correctly this may help to reduce the requirement for bought-in fertilizers – which is not only good for the environment but also for your pocket!

As the nutrients within aerated slurry are uniformly distributed it is much easier to calculate application rates accurately as each load spread is the same.

Many farmers have reported quicker re-growth of grass and increased palatability after spreading with slurry which has been conditioned by using Ameram Aeromixer. It is also kinder to beneficial soil life such as earthworms.

We know that slurry mixing is a difficult process; however, using the Ameram Aeromixer makes it an easier job!

The compressor is activated by the digital clock within the control panel. Air is fed into the primary rotary valve which feeds the 12, 16 or 20 port rotary distribution valves, which are fixed to the top of the tank or to the walls above a cellar.

The rotary distribution valves are connected by polyethylene pipe to the 2 or 4 outlet manifolds which are securely fixed to the floor with stainless steel fixings. Only 1 port, in the whole system is “live” at any time, causing air to be jetted out at 2 or 4 specific points. The pneumatic rotary distribution valve then revolves to open the next port.

The system operates during the night for the amount of time required dependent upon the size of tank to be mixed.


Our design is the result of experience.

Hook & Claw Compressor

The Ameram Hook & Claw Compressor is the driving force behind the system. Hook & Claw compressors are ‘non-contact’ compressors – that means that the moving parts do not rub on each other and wear out and need no lubrication. Vane compressors and piston compressors are ‘contact’ compressors – there is rubbing and wear, possibly a need for lubrication.

‘Compressors’ are different from ‘blowers’. A compressor captures air and squeezes it before expelling it to the outlet piping. This ensures that the volume of air ejected remains reasonably constant whatever the outlet pressure is. The simplest form of blower is a fan. Fans move a great deal of air but the volume of air shifted is directly related to the pressure in the outlet piping. As the pressure goes up the volume shifted goes down.

Root blowers are fans of improved design which generate considerable pressure but do not compress air within the machine. Because back-flow within the fan increases as back-pressure goes up the output of a Roots blower falls. The selection of the Hook & Claw design offer the most efficient of air compressors with the lowest wear, the lowest maintenance requirement and precise delivery of air volume – whatever the depth of slurry in store.

Ameram Hook & Claw compressors can operate on 3-phase electricity (380/450VAC 50 or 60 Hz) or, at a slight increase in price, single phase (230VAC). For shallow cellars 3KW 1 or 3-phase (20! 230VAC supply required). For silos above 3m deep but less than 6m deep – 4KW – 1 or 3-phase. For silos and lagoons 6m to 10m deep – 5.5KW – 3-phase only.

Ameram Aeromix Systems require regular but little maintenance. Typically the maintenance requirement is an annual 1 litre change of gear oil and a change of inlet air filter. Less than €20 per year. The distribution valves require no maintenance.
