volume flows from approximately 30 m³/h to 15.000 m³/h and overpressures up to 1000 mbar. The Delta Blower series is designed for oil-free conveyance of air and neutral gases.

Special advantages speak for the use of Aerzen DELTA BLOWER Generation 5

• Low noice levels due to considerable sound reductions
• Operation-friendly & low maintenance design
• Mechanical fan
• No absorption material
• Space-saving side-by-side setup

The new generation Delta Blower G5plus is on the market!

AERZEN has developed the successful concept with the new Delta Blower G5plus and raised it to the next technological level. Apart from the known advantages of the series, it is the new compact design that attracts attention. It allows a space saving side-by-side installation and requires less space in the machine room.  All blowers achieve oil-free operation class 0 as per ISO 8573-1 according to the AERZEN Environmental Concept. They are free of absorption material up to 100 % and require oil change only after 16,000 operating hours.  Energy-efficient motors class IE3 are used as standard and suction is still at the cold side of the assembly.

What is absolutely new with the Delta Blower G5plus is up to five per cent energy saving by means of an optimised intake filter silencer with lowest flow losses, high-efficient electrically driven fans and an optimised standard base support which makes reduced pressure losses possible. The warm exhaust air is routed over the roof of the acoustic hood to connect a separate channel for optional heat recovery. But the “plus” also refers to the additional comfort of Delta Blower G5plus: The new acoustic hood concept reduces the installation surface area by up to 10 % depending on the size and the acoustic hood door makes easier and faster access possible to facilitate the maintenance of the assembly. The multifunctional, extended base support creates a plus of flexibility by an integrated spark arrester (ATEX), the preparation for installation of a start unloading device, components for installation of third-party motors and a patented reactive silencer.

AERZEN supplies the technically optimised and conceptionally enhanced Delta Blower G5plus positive displacement blower in four sizes for volume flows of 440 m³/h up to maximum 3,600 m3/h.

Rotary lobe compressor packages Delta Hybrid

The rotary lobe compressor is one of the most innovative solutions in compressor technology, and one of the most efficient machines by far in the vast 25 to 100 per cent control range. Delta Hybrid has long been the only packaged unit in the world to bring together the benefits of blower and compressor technology in one single unit. For completely new possibilities in creating positive and negative pressure. And for savings of up to 15 per cent.

The successful AERZEN Rotary Lobe Compressor packages have been designed for oil free compression of air and neutral gases. The Delta Hybrid is currently available for positive pressure and vacuum applications in the range of nominal nozzle sizes DN 100 to DN 300 (4 in. to 12 in.). A flexible modular concept enables the combination of multiple machine and motor sizes within a nominal package size. When equipped with the most suitable belt drive, the current performance requirement can be met most closely while enabling possible later easy adjustments.

The new and successful Delta Hybrid series covers a flow range of 110 m³/h to 9.000 m³/h (65 to 5300 cfm) with 16 machine sizes and for positive pressures (depending on the size) up to 1500 mbar g. (22 psig) and vacuum to -700 mbar (-21"Hg). Beside the former sizes S and L as well as H for higher pressures, the varied rotary lobe compressor kit is now also available as E option for special negative pressure applications.

Rotary lobe compressor stage Delta Hybrid D 98 V

AERZEN Delta Hybrid D 98 V, the innovative rotary lobe compressor stage with pre-inlet channel for pressure ranges from -950 to 1,500 mbar

With -950 mbar very close to the vacuum. For a decisive plus of efficiency.

Delta Hybrid is one of the most innovative and most successful series of compressor technology. The symbiosis of positive displacement blowers and screw compressors does not only provide increased energy efficiency by up to 20% but also exceeds the limits of the usual range of application. The new D 98 V achieves an overpressure of 1,500 mbar and a negative pressure of -950 mbar at full capacity. Consequently, you will reach the vacuum range with the innovative AERZEN compressor stage.

Minus 950 mbar - the new performance category for negative pressure.

The further development of D 98 V is based on a technical innovation. The newly designed and optimised pre-inlet channels provide a targeted cooling in the range of the compression process which is mostly temperature intense. The negative pressure of -700 mbar, which is already high at standard, can even be increased up to -950 mbar. This new performance class surpasses the possibilities of conventional positive displacement blowers and screw compressors by a multiple.

6% lower energy usage compared to conventional compressors – the AERZEN E-class (VML 60 G5-E, VML 95 G5-E, VM 45 G5-E, VM 75 G5-E) is making a significant contribution to the realisation of legal and company energy savings programs. And with almost 90% of total costs taken up by energy, this means releasing serious potential that can be devoted to environmental protection, improved company liquidity, and reduced life-cycle costs.

Screw compressor units Delta Screw with belt drive

For compressing air, nitrogen and other neutral gases.

The single-stage, oil-free screw compressors in the Delta Screw Generation 5 plus series are universal tools. They bundle all the know-how of a world market leader in compressor technology to offer you ‘the user’ maximum efficiency. These innovative machines are belt-driven to provide air and nitrogen applications at positive pressure, negative pressure, and in a range of nominal sizes. The flexible modular system allows for almost any combination of compressors and accessory components. The belt drive allows for optimal adaptation of the system to the job at hand, as well as for any changes that may become necessary later. In addition, the belt drive allows for precise configuration – an important feature given that the greatest savings come from saving energy. This means, for example, that a 5% deviation in the volume stream means a 5% increase in energy consumption.
