The AUGUST S-T (variable frequency) Variable Speed
Drive VSD Series is designed as a total concept, rather
than by adding a frequency converter to an existing
machine, it is tightly integrated and mechanically tested
and has low vibration at high performance.
Main benefits are a highly stable air net pressure, low
starting currents, a total absence of peaks and a high
power factor.

By varying the speed of the drive motor, the AUGUST S-T (variable frequency) Variable Speed Drive VSD Series compressor
output closely follows the air demand by covering
Shaft power(%)
a wide range, without load-unload switching. The
result is a constant pressure, without fluctuations,
Standard Screw Air Compressor
which greatly benefits to your overall process stability.
Furthermore, a great energy saving between 20%
and 35% is achieved during partial load. The reduction
in energy cost over a typical life cycle might even
surpass the initial investment cost of the screw air
compressor. In other words, the savings realized
by VSD can pay for the entire machine.

The AUGUST S-T (variable frequency) Variable Speed Drive VSD Series comes in a ready-to-use package with many included
standard features. The highly silencing canopy reduces the noise level to a mere 69-77db (A).
The compressor is delivered with an IP54 water and dust protected motor. (IP55 available upon request) The unit and the
integrated frequency converter are controlled by microprocessor control and monitoring system.
This is enabling the Network buil ding for an ev en more efficient use of the AUGUST brand compressor, by combing a regular
drive AUGUST screw air compressor with the AUGUST S-T series AUGUST VSD compressor. As a result of the networking
you get the fully automatic function , that the AUGUST S-T VSD compressor is only filling up the current demand of the
air, while the standard AUGUST screw air compressor is doing the base load of the air tank whenever required by the work
load. This is the most efficient way of use of VSD.

VSD provides a soft start similar to a Y- transformation or electronic starter. This is extending the all over life time of the
compressor unit and reducing costs for mainte nance. Also the down-time can be reduced significantly and no or low
vibration can extend the product life cycle too.
In the low speed period, the AUGUST VSD compressor is convincing by a comfortable noise level but will still only be between
69-77db (A) (depending on model) at full load, which will have a positive influence on the working environment and might
even increase the productivity of nearby workstations.
Further advantage of the VSD AUGUST S-T series is the application in countries with 50Hz as well as 60HZ electric frequency.
A selected variation of voltages can als o be supplied u pon y our r eques t.A ll models o f the series co mpl y wit h the C E certificat ion
and when required have the ASME approved oil-air separator.
Energy efficiency
Independent studies have shown that energy can mount up to over 70% of a compressor's lif ecy cle costs. In some cases
the generating of compressed air can account for more than 40% of a plant's total electricity bill. Most production environments
have a fluctuating air demand depending on the time of day, week, or even months of the year from 35 to 78%.

b. Investment
c. Maintenance
d. Average 36% Energy Savings
Because there is no unnecessary power generated, the VSD can reduce energy costs by 36% or more. Cost
reductions can average 22% over the entire lifecycle of the compressor. In general, the extra cost of a VSD
compressor compared to a fixed speed one is earned back after just about two to three years.
AUGUST VSD reduces energy costs by
* Avoiding electricity surges by Increasing flexibility with soft starting gradual motor up.
* Avoiding operation at no load power compared with conventional compressors at light load. Eliminating the inefficient
transition period from full to no load power.
* Maintaining the net pressure band to within 0.10 bar, 0.01 Mpa
* Reducing overall average working pressure.
* Minimizing system leakage due to a lower system pressure.
* Preventing components from early aging cause by prolonged full load operation urrents, a total absence of peaks and a
high power factor.
