You may think you know pretty much everything there is to know about vacuums. You push one around your house to pick up dust on the floor
and that’s about all there is to it.
Far from it.
Vacuums are used in so many places, and for so many purposes, that it’s almost mind-boggling. Think of the package of yogurt you sometimes
have in the morning. A vacuum was used to make that packaging and keep the yogurt fresh. You’ve had a soda before, right? Vacuum pumps are
used to make those cans!
When paper is manufactured, the heavier loads are lifted and forwarded using vacuum pumps. In hospital rooms, there are bound to be vacuum
pumps for various applications such as using suction during surgery.
And it is unfathomable for virtually any segment of the computer industry not to use a vacuum pump.
You would be hard-pressed to find an industry that doesn’t use vacuum pumps. They keep our food fresh and enhance our lives. They simplify,
accelerate, and lower
costs of manufacturing
Let's learn about the difference types of Vacuum Pumps
Vacuum Pump Technologies
Rotary Vane Vacuum Pump: A rotary vane pump consists of sliding vanes mounted in a spinning rotor within a pump
housing. This rotor is offset, resulting in varying pockets sizes between the rotor and housing. These pockets reduce in size
traveling from the inlet side of the pump to the discharge side; this creates suction of the gas from the connected process or
chamber.
Screw Vacuum Pump: Screw technology utilizes two mating screw rotors rotating in opposite directions. A volume
of gas is trapped between the screws and the housing at one end. As the gas travels the length of the screws it is compressed and
discharged on the opposite end. Some advantages of this technology are reduced heat load, smoother operation, greater efficiency, and
more turn-down capability.
Liquid Ring Vacuum Pump: Liquid ring vacuum pumps require a seal liquid to function; the most common liquid is
water. An eccentrically installed impeller rotates in the casing partly filled with liquid. By the rotational movement of the
impeller, centrifugal force throws the liquid outward. Gas is trapped in the spaces between the impeller vanes and the liquid ring. Due
to the eccentric installation of the impeller, the spaces enlarge, and the process gas is sucked in through the inlet port. As the
impeller further rotates, the spaces shrink so the gas gets compressed and discharged through the discharge port.
Claw Vacuum Pump: This type consists of two claw-shaped rotors turned in opposite directions inside a housing. The
interlocking shape of the rotors makes it possible for the air or gas to be drawn in at a large volume, compressed, and then discharged. Due
to the tight clearances, these pumps do not require liquid to seal and lubricate the vacuum pump. This makes the claw vacuum extremely
robust and able to withstand harsh operating conditions.
The Ash Air range of rotary claw vacuum pumps is the best alternative to rotary vane pumps. A vacuum claw pump is virtually zero maintenance and compared to rotary vane pumps can work at vacuum levels of 400 to 1000 mbar without overheating. Rotary claw vacuum pumps are the best choice for CNC guided wood routers.
The Ash Air range of humble liquid ring pumps is still the most reliable form of large volume vacuum generation available today. These liquid ring pumps are simple to use and very reliable, and the best option when sucked air contains a large amount of saturated gas.
Dry and oil-sealed vane vacuum pumps are robust, affordable and easy in maintenance. You can use DVP vane pumps for wide range of application, for skin packaging, holding, lifting, thermoforming.

A common questions asked is why do I need an air dryer for my compressor? Typically, air compressors produce water, and although the
water can be drained, there can still be aerosol and vapour droplets that are present. This is because water cannoet be compressed. Water
can damage your compressor by corroding the valves, pipes and machinery controls, which will cost you time and money to resolve. In
the long run, the cost of a new compressor is a small price to pay compared to the loss of production that could potentially arise due
to water damage in your compressor.
Air compressors can fail for an assortment of different reasons: Normal wear and tear, lifespan and age of the unit, poor maintenance, power surge, install issues are just a few the come to mind. Check out this blog to find out our top 7 tips to ensure your compressor is looked
after!

We Kiwi's love our Coffee! Coffee, like all other food & beverage products, must go through a preservation process to keep the
beans fresh during storage and packaging before they reach the consumer. Coffee that is not properly stored after it is roasted will lose a
large amount of carbon dioxide, which lessens its' flavor and speeds up the staling process. One of the most common ways to preserve the
freshness of coffee is the use of nitrogen gas. Learn more here:

system which should be located away from heat sources such as the compressed air outlet, refrigeration or air conditioning plant and
equipment.
