15 LINN The vacuumchamber is alsomade of grey cast iron. The propeller has been specially developed by us for „dirty water“ applica- tions. The material used is a particularly hard bronze alloy (tungsten carbide bron- ze). This ensures long operating times. Wear and tear on the propeller is hardly noticeable even after several years of ope- ration. The propeller shape was developed in such a way that no blockages or deposits are possible. The free passage in the pro- peller core ensures the addition of air. The dimensioning ensures trouble-free conti- nuous operation. The easiest way to use our ventilation sys- tem is in a floating version. We supply this waste water aerator completely ready for operation. Aeration aggregate and float form a compact, firmly connected unit. Practical carrying handles on the float allow two people to carry and insert the unit without lifting gear or the like. The devices are relatively light and easy to handle. The float is made of PE plastic as a hollowbody and is very robust. The foaming of the cavities known from GFK floats is not necessary with our high-quality floats! TURBO-JET floating can be optimally used for expansion or retrofitting - but also for original equipment. The floating unit only has to be placed on the waste water, pulled to the desired position with the aid of stainless steel wire ropes and at- tached to the edge. Then all you need is a connection to the power supply! It couldn‘t be simpler - or faster or cheaper. Consider the cost sa- vings by omitting the installation (electri- city connection excluded). Turbo-Jet 1.1kW - three aerators working in an oxidation pond TURBO-JET in floating design is particu- larly suitable for pools with fluctuating water levels, as the propeller immersion depth of floating units is always constant and therefore always optimal, while per- manently installed units have problems here. The TURBO-JET floating aerator is also available in some special versions. For example, we manufacture a variant with two floats. This device is designed in such a way that it can be inserted into a pool through a 60 cm man hole. Only the two floats (approx. 20 x 20 x 100 cm) still have to be fixed in the tank! In tanks, this unit can easily be locked in place with two ver- tical guide tubes (mounted on the pool floor and guided by the handles on the floats). The aerator can float up and down according to the water level on these special version - to use in closed tanks with manhole ADVANTAGES: l flexible and versatile l minimumenergy consumption l good oxygen input l large circulation l low acquisition costs – fast amortisation l lowmaintenance costs l no installation l no laying of air ducts l no constructionwork l absolutely winterproof l immediately usable l almost noiseless guide pipes. An additionally mounted stand protects the propeller from dama- ge when the tank is completely emptied. Here, too, you can see how versatile our system is!
