Customers Benefit from Technical Progress

The Delta Blower Generation 5 is the synthesis of the successful characteristics developed in previous generations combined with new technical innovations that already meet the market requirements of the future.

Why Generation 5?

Aerzener Maschinenfabrik was the first blower manufacturer to design a compact unit in 1960 and has developed this machine type continuously ever since.

Delta Blower Generation 5 is therefore the fifth generation of Aerzen blower units and represents the successful combination of tradition and innovation. However compared to other blower models this new series offers 5 main advantages for the customers. 5 main advantages which led to the name "Generation 5".

Lower Sound Levels

Compared with the previous generation the sound levels of the Delta Blower Generation 5 series have been reduced by an average of 6 - 8 dB(A), in some single cases even lower sound levels have been achieved. The silencing system within the units is totally reactive; therefore the danger of contamination from absorption material is
eliminated. Due to these considerable sound reductions, expensive measures, such as special acoustic hoods are no longer required.

Simple Operation and Easy Maintenance

During development, special consideration was given to the ease of handling of the new units. The first consideration was easy positioning and installation:

The units can be transported at site, by means of a suitable fork or pallet truck. They are delivered with a service pack that includes a lifting jack, oil funnel and an initial fill of oil, which also makes commissioning very easy. All service tasks and components that require maintenance are accessible from the front of the unit.

However, the important advantage is the new oil system. The oil level can be viewed and checked from the outside with the blower fully operational, this is possible without any problems. Therefore, blower shutdowns, process and production interruptions belong to the past.

Mechanical Fan

A mechanical fan mounted on the blower drive shaft is used to ventilate the acoustic hood. Without the need for an electric fan additional electrical installation and energy costs are saved.

An additional advantage for this system is that it fully complies with all ATEX requirements. Expensive ex-proof fan motors are not required - a considerable cost saving.

Absorption Material Eliminated

Delta Blower Gen5 Überdruck - Verschleiß

The base for the Generation 5 blower is also the discharge silencer in which the sound level is reduced by diverting the air flow. Absorption material which is subject to degradation has not been used in any part of the unit.

The downstream system cannot become contaminated when it is used for pneumatic conveying of bulk food materials and the integrity of the foodstuff is guaranteed. In the sewage industry, the blockage of an aeration system can be avoided; costly maintenance expenditure is minimized and production losses are eliminated.

Space Saving Design

Especially with the smaller size units the dimensions have been reduced, linked with the facility to install the units "side by side", the required floor space has also been considerably reduced. Providing further cost savings in designing the size of the blower room. Due to the changed dimensions and type of design there is a better possibility of replacement regarding the previous Aerzen generations KI, KII and KIII.

9 sizes in 5 nominal widths:

Less room needed due to compact design and installation variant "Side-by-Side".
