Pumping speed
Air pumping speed provided by the vacuum sealer.
The
higher the speed, the less time it will take to operate the device. In addition, "faster" models tend to be more powerful and can deliver deeper vacuums. On the other hand, in normal household use, these points are not critical, and when choosing a "home" sealer, you can not pay much attention to the pumping speed — unless you have to regularly pack large volumes of products, or storage time is crucial.
Suction power
Suction power provided by the vacuum sealer.
This parameter directly characterizes the capabilities of the device to create a vacuum. Suction power is the difference between normal atmospheric pressure (1 bar) and the lowest pressure that this model can create inside the package. For example, a figure of 0.8 bar means that the packer can create a pressure of 1 – 0.8 = 0.2 bar. Accordingly, the higher the number in this point, the more powerful the sealer, the deeper the vacuum it creates.
In general, if the products are packed at home for relatively short storage (or vacuuming is combined with freezing), this indicator can be ignored. But for professional use, high suction power is fundamental.
Power consumption
Rated power consumption of the device. Usually, the characteristics indicate the average power in normal operation; peak values can be much higher, but this mode does not last long.
On the one hand, the efficiency and speed of vacuuming directly depend on the power consumption, on the other hand, the consumption of electricity. And heavy high consumption industrial-grade devices may require a three-phase connection (see "Power supply").
Power supply
The power supply used in the vacuum sealer.
- Power supply (230 W). Powered by an ordinary 230 W household outlet. This is a convenient and practical option, and therefore it is found in almost all types of sealers. The only exceptions are heavy powerful units rated for 400 W, as well as some manual models, where a battery is used for added convenience (see below).
- Power supply (380 W). Powered by 380 W three-phase mains. Used exclusively in high-performance industrial-grade devices for which single-phase power is not enough.
- Accumulator. Power supply from the built-in battery is found in manual sealers (see "Purpose"). This option is convenient in that the power cord does not stretch behind the device during operation. On the other hand, rechargeable models are heavier and more expensive than similar devices powered by the mains, and they have a limited life, when the charge is exhausted, you will inevitably have to pause to recharge the battery.
