Single responsibility
- Integrated and modular design: the entire blower package is designed,
built, supplied and supported by the blower manufacturer: Aerzen.
Safety and reliability
- Safety and Reliability by design: from the casing to the rotors
and shafts, from helical gears and bearing selection to internal seals.
Precision machining and assembling, and a full-load performance test
of each machine prior to shipment ensure quality. The blower is then
combined with accessories specifically designed by Aerzen to match the
quality
built
into the machine: low vibrations, low pulsation levels, no contamination
of the air or gas stream, low pressure losses, great accessibility
and ease of maintenance. Instrumentation is offered to protect the
machine against
overloads and the vibration level can be monitored as an option.
- The internal seals on the Aerzen rotary lobe blowers and oil-free
screw compressors are in use in thousands of food, milling, and pharmaceutical
applications worldwide. Like
the bearings, the internal seals are designed for a minimum of 5 years
of continuous operation at full load.
Clean on the outside and also on the inside
- The internal seals on the Aerzen rotary lobe blowers and oil-free
screw compressors are in use in thousands of foods, milling and pharmaceutical
applications worldwide. They most reliably keep the air clean free
from the lubricating oil. As non-friction seals, and like the bearings,
they
are designed for a minimum of 5 years of continuous operation.
- Aerzen solid or dust-tight capped rotors will stay internally
clean and free of dust.
- The inlet filter is the last item the air touches before entering
the rotor chamber of the blower. This is important because....
- The discharge silencer does not contain absorption materials.
Quiet operation
- Completely integrated acoustic treatment solution beginning with
the heart of the package: Aerzen positive displacement blower that
all but eliminates already on formation the air stream pulsations inherent
to PD
blowers in its patented wave-interference channels.
- Acoustic hood with quick-release panels that give easy access
to all components of the package to fulfill the already minimized
maintenance tasks. And, as our customers expect from an environmentally
conscious supplier, the entire package with hood is mounted on a permanent
steel skid that also forms an oil-drip pan and reduces installation
time to a minimum.
Little, easy maintenance
- On the AERZEN belt-driven blower packages,
the belt tension is automatically maintained, therefore avoiding belt
slippage or over-tensioning. There are no springs and no tension rails
that would require attention and periodic adjustments. This not only
reduces maintenance to a minimum: it contributes to reliability, efficiency
and durability.
- Filters with high dust retention capability extend the cleaning
or replacement intervals
- Oil changes typically yearly
- Typically mean time between overhauls (MTBO) at full load:
5 years
- Changes of belts : typically every 2 years
If your current blower is unreliable, we offer retrofit engineering
services. Contact our sales engineers for an objective and thorough payback
analysis and/or discussion on this subject. Case studies and extensive
references available.
