The new high-efficiency air conditioning and refrigeration systems are more subject to damage due to contaminants. The new oils used to require a stronger vacuum to remove moisture from the circuits.

A vacuum of 25µ microns is optimal for eliminating humidity which can cause failure and unpaid warranty interventions. The choice of a vacuum pump is determined by the ability to quickly evacuate a circuit, as the humidity contained in the air reduces the efficiency of the system, creating serious problems such as compressor failures.

Our vacuum pumps are designed to remove as much moisture as possible by reducing the pressure inside the cooling circuit. This drop in pressure boils and evaporates the moisture which will then be expelled outside.

Here we have listed the Best Car Vacuums. These vacuums will be great for a person who wants his car clean.

Decisive Factors for The Choice of The Car Vacuum 

1. Pump

When choosing the vacuum machine, the work done by the pump of the machine itself is important. The pump is the mechanism that allows the machine to suck the air from the bag or container where you will insert the food to be stored, thus creating a vacuum. Specifically, for vacuum machines we speak of membrane pumps.

The Void

The greater the value of the vacuum, the lesser the quantity of air that remains in contact with the vacuum-packed food, and consequently the greater its ability to conserve over time.

You can find the vacuum value expressed in different ways: suction power, maximum depression, vacuum value. This value is expressed in mbar, and is expressed both with a positive sign and with a negative sign.

For example, a machine that aspires at -800 mbar (or 800), compared to 1000 mbar (approximate value of the atmospheric pressure at sea level) leaves 200 mbar in the bag. If it aspires to -900 mbar it will leave 100 mbar inside the bag.

If you are looking for a model that will keep you for a long time the food you will have to opt for a vacuum machine that has a good suction power (or vacuum value).

The models with low vacuum values ​​are around 500/600/700 mbar.

To date, many vacuum machines have a suction power of around 800 mbar. We specify that this is usually a nominal, i.e. theoretical, data given by the manufacturers of the diaphragm pumps: in reality, there are many variables that influence the level of vacuum that will be created inside the bag (actually measurable with a special vacuum gauge, if not provided on the machine itself).

The best values ​​are those values ​​(inside the bag) that approach the absolute vacuum value: 0. Vacuum values ​​that approach this value can only be obtained with highly professional machines (usually bell-shaped vacuum machines) and not with domestic use.

To keep in mind: since we talked about atmospheric pressure, remember that not all vacuum machines operate at high altitudes (above 1000 m).

When Evaluating the Pump of A Vacuum Machine, These Aspects Must Also Be Taken Into Consideration :

  1. Double Pump: some machines are equipped with two pumps; these have the advantage of distributing the workload to carry out the vacuum going to stress less a single pump; this means greater durability of the machine over time
  2. Flow Rate: this is expressed in l / min or dm3 / min. The value expresses the speed with which the air is sucked from the bag/container. The higher the flow rate, the higher the pump performance and the speed with which the machine will vacuum, but not always a high flow rate value is what
  3. You Need: a low flow rate will make the machine suck the air more slowly from the bag, and this could help you in case you intend to store fragile or very juicy foods as the liquid that will come out of the food will rise along with the bag (bag) much more slowly than a machine with a greater capacity vacuum machine suction power Example of a vacuum machine with double pump and flow rate of 20 liters per minute

2. Power

Power is expressed in Watts (W). The data shown in the datasheet of the vacuum machines are a total calculation of the electrical energy that is used by the pump motor (membrane) of the vacuum machine and to heat the sealing bar (or sealant).

The higher the value expressed in Watts, the greater the performance over time of the machine as a more powerful motor will be able to withstand a greater workload vacuum machine power

Example of A Vacuum Machine with 100 Watts of Power

The power that will then be used by the sealing bar of the machine, the maximum value indicated in the technical data sheet, is important to ensure good sealing and therefore to seal the bag in which the vacuum is made and the heating speed of the sealing bar itself.

All this also, therefore, affects the tightness of the vacuum over time: a machine that has a high power will weld the bag in a short time and will be able to have less problems if there is liquid between the two edges of the bag (derived from the conservation of more juicy foods).

Machines with longer sealing bars (over 30 cm standard) usually exploit higher powers.

3. Functions

Another important factor to evaluate in vacuum machines is the presence of different functions. The functions vary according to the machine and are characterized by a) vacuum levels, b) flow rates and c) different welding times to store different types of food.

The greater the number of functions, the more versatile the machine will be vacuum machine functions menu

The menu of a vacuum machine with many functions, including manual welding . Below we list the most interesting functions of vacuum machines.

Manual Welding

Allows you to weld without vacuuming. This function is useful if you buy a roll and want to weld one of its ends to make a bag or to simply close the food without storing it under vacuum.

There are vacuum machines in which it is possible to adjust the welding times and others in which these vary according to the selected function.

In machines where you can choose to weld only and where you can choose the welding times (in machines for domestic use, with large consumption, they are preset) you can:

Work on Bags of Different Thickness

Lower Welding Times: you think you have made many consecutive welds and that the bar has overheated you can go to lower welding times in order to prevent the bag from “melting”

Increase the Welding Time: to increase the probability of sealing the welding in the event of more humid foods being stored

Usually machines, where it is possible to switch to manual welding, allow you to do this by interrupting the automatic cycle, in particular, the suction phase and going to weld.

This means that, even without the special function for more “humid” or “fragile” foods, you can decide how to use the machine, when to stop the suction phase and go directly to the welding, precisely, of the bag. In terms of vacuum you will have lower values ​​inside the bag.

4. Accessories

Vacuum Machines Are Not Supplied with Many Accessories. Almost All of Them Are Supplied with Pre-Cut Bags, Usually of Different Sizes. However, They Are Not so Numerous, so You Should Immediately Buy Some of Them Together with Those Supplied with The Machine Vacuum Machine Accessory Kit

The Accessory Kit of A Vacuum Machine that Includes Two Types of Bags Based on The Price, Important Discriminant, You Can Also Find Other Accessories :

  1. Roll: To Create Your Bags for Packaging
  2. Cutter: If Not Integrated in The Machine to Cut the Roll
  3. Accessory Containers
  4. Tube to Create the Vacuum in Separate Containers Liquid Vacuum Tube
  5. Adapters: One Part Will Go to The Tube, the Other to The Container Lid
  6. Caps: For The Vacuum in The Bottles
  7. Valves: Here We Are Talking About a Particular Brand that Sells Valves to Make the Vacuum in The Classic Preserving Jars (eg Bormioli)
  8. Accessories for Glass Containers: Using Special Universal Lids, Adapters, Lids, and Rings (in Metal Such as The Caps of The Cans) You Can Create the Vacuum in The Glass Jars

Pay attention to the quality of the accessories supplied. For example, the embossed bags are better than the smooth ones because they guarantee better performance by facilitating the exit of the air vacuum bag machine

Example of An Embossed Bag Supplied with A Vacuum Machine

If you intend to cook at low temperatures, check that the bags are suitable for boiling, for use in the microwave and in the oven at low temperatures. Also check that the bags are free of Bpa, i.e. Bisphenol a potentially harmful substance.

Finally, for those who do not like waste, it can be a good idea to check that the bags are reusable and/or dishwasher safe.

5. Dimensions

Vacuum machines are usually used in the kitchen (some are suitable for packing clothes and other objects, even archaeological finds).

This implies that they will occupy space on the work surface. In this regard, there are machines that are designed precisely to reduce this size, being able to be arranged both horizontally and vertically.

However, the dimensions of a vacuum machine also depend on whether they have internally integrated the space for the accessory roll and the associated cutter (which on the one hand avoids having to find the place in the drawers right on the roll).

Then there are machines that develop only vertically and they also have space for the accessory roll.

In Summary, with The Same Features, a Smaller Footprint on The Kitchen Top Is Certainly an Advantage.Sealing Bar Dimensions Evaluate There Is Also the Weight of The Machine, Influenced by The Construction Materials:

The greater the weight the greater the stability during the work of the machine. It should be considered, however, if you intend to store it in a place other than the work surface: in that case, a heavy machine could be uncomfortable.

Since we are talking about dimensions, there is another parameter to evaluate: the dimensions of the sealing bar (or sealing bar). Household models have a bar with standard dimensions:30 cm. this size goes hand in hand with the size of the bags and the food to be packed.

More professional models allow you to choose the length of the sealing bar: 30, 33, 35, 40, 50, 60, 80 cm (for example the Elegen or the Orved).

It is also important to evaluate the thickness of the sealing bar: if it is true that a good power and related production materials allow a homogeneous sealing section with a good seal, it is also true that having a thicker or even double bar allows for greater security on the vacuum seal inside the bag.double sealing bar vacuum machine

Example of A Vacuum Machine with Double Sealing Bar

Having a greater thickness implies that over a long stretch the chances are increased that there are no “defects” in the weld. Two sealing bars in series, on the other hand, make it possible to have a better seal and also guarantees at least the functioning of one bar in case the other has problems of operation.
