Multi Venturi Design:
Some of HyVac's’ vacuum venturis incorporate a series of nozzles.
Each nozzle has a progressively larger orifice selected to extract the
maximum amount of energy from the compressed air flowing through it.
This optimizes the levels of vacuum generated.
Normally, no special pre filters are required because the venturi
nozzles are aligned to allow "straight through" air flow. Thus
any air line contaminants or condensable easily clear the generator
without clogging or building up.
Air Driven: Venturis’
are easy to install. They operate efficiently on shop air (20-90 PSI) and
are well suited for explosion-proof applications. There is no RF noise
generated to effect electrical or electronic systems. These units
can be arranged together in a manifold to increase flow if needed.
Size: Allows the pump as the
vacuum source to be placement closer to the point of use. Shorter air
lines cost less and quicken the response time.
Weight Construction: Most
models weigh less then two pounds providing maximum flexibility and
Control: Vacuum levels are
controlled by adjusting inlet pressure. Pumps can be cycled on and off by
controlling inlet pressure rather then the vacuum line. Thus, there is no
wasted energy. Control may be
manual or automated. Vacuum
pressure may also be adjusted on the vacuum side by using ¼ turn ball
valves or introducing another form of leak.
Parts: Expect extra long pump
life with no lubrication required.
Operation: All multi-venturi
pumps come equipped with the HyVac straight through air flow silencers.
The silencers muffle exhausted air resulting in low noise levels in the
60-65db range, without creating back pressure on the pump or air pressure
construction. Pumps are
standard in aluminum but can be manufactured in other materials such as
stainless steel for corrosive applications.
