Within the compressor body
there are two screws with matting profile: a female and
a male screw, female having concave inlets and the male
with convex helical inlets. The screws rotate in
opposite directions with the female screw receiving the
driving power and transmitting this power to the male
screw through a set of synchronization gears.
As the screws rotate, the
air is drawn into the inlet port and fills up the space
between the screws. This phase is the Admission. The key
phase is the Compression. It starts when the end of a
male thread blocks the end of a female thread. The
volume available between the compressor body and these
two threads then progressively decreased during
rotation. When this volume merges into the delivery
outlet of the compressor, the third phase takes place,
hence the Exhaust.
Throughout this process,
there is no contact between the screws. This means no
wear, total reliability, and non-pulsating air delivery.
These compressor/blowers can be used in either a Mobile
or stationary application and can be driven by a PTO,
electric motor, or hydraulic power system. A complete
range of dedicated ancillary product is available to
support this product line.
