<\/span><\/div>When a workshop or food business considers vacuum packing, the same doubt almost always comes up: chamber or tabletop? tabletop or floor-standing? And behind that doubt there’s usually a misunderstanding that costs money.<\/p>\n
Let’s clear it up from the start, because choosing for the wrong reason leads either to falling short on capacity or to paying for a bigger machine than you need. You can see the full range on our vacuum sealers page<\/a>.<\/p>\nThe myth worth clearing up: the tabletop is also a chamber machine<\/h2>\n<\/div><\/lite-youtube><\/div><\/div>There’s an idea that a “tabletop” sealer is a different, lower-quality machine than a “chamber” one. In Tecnotrip’s case, that’s not true.<\/p>\n<\/div>

<\/span><\/div>Our entire vacuum range is chamber-based: the product goes inside a chamber that closes, and the vacuum is created throughout it. A tabletop sealer like the EVT-7 has a real chamber (430\u00d7440\u00d7205 mm), a double sealing bar and even a gas-injection version. It’s a chamber machine; the only thing that changes versus a floor unit is format and size, not the system.<\/p>\n
What does that mean in practice?<\/h3>\n\n- The vacuum level a tabletop chamber reaches is the same type as a big one’s. It doesn’t pull “less vacuum” for being small.<\/li>\n
- It works with the same flat bags, which are cheaper.<\/li>\n
- It can pack liquids and wet products, because the vacuum is created in the chamber, not by suction from the bag.<\/li>\n
- Many models support gas injection (modified atmosphere).<\/li>\n<\/ul>\n
That said, not every chamber machine suits every job. What really makes the difference is something else.<\/p>\n
So what actually changes between formats?<\/h2>\n
If the system is the same, the choice comes down to four concrete, measurable variables:<\/p>\n
\n- Chamber size.<\/strong> It determines which pieces and how many bags fit per cycle. It ranges from 300\u00d7320 mm on a compact unit to over 1,180 mm long on floor units, or even 916 mm on a tabletop built for long pieces.<\/li>\n
- Vacuum pump capacity (m\u00b3\/h).<\/strong> It doesn’t change the final vacuum or the number of cycles: the pump is sized to the chamber volume. A larger chamber needs more capacity to pull the vacuum in that bigger space within a reasonable time. That’s why the capacity grows with chamber size: from 8 m\u00b3\/h on the most compact unit to 250-300 m\u00b3\/h on those with the largest chamber.<\/li>\n
- Format: tabletop or floor.<\/strong> A matter of space and ergonomics. The tabletop fits on a countertop; the floor unit is a fixed machine with a larger chamber and pump.<\/li>\n
- Cadence: single chamber or double chamber.<\/strong> The double chamber seals one batch while the other is loaded, so the operator doesn’t wait for the cycle. That’s what multiplies packs per shift.<\/li>\n<\/ul>\n
With these four variables, the conversation stops being “chamber or tabletop?” and becomes “which chamber, which pump and which cadence do I need?”.<\/p>\n
The tabletop chamber: when it’s the right choice<\/h2>\n
The tabletop vacuum sealer is the option for workshops, butcher’s shops, producers and low-to-medium volumes with limited space. It fits on a countertop, installs easily and pulls a genuine chamber vacuum.<\/p>\n
Some real examples from the Tecnotrip range:<\/p>\n
\n- EVT-14<\/strong> \u2014 chamber 300\u00d7320\u00d7120 mm, 8 m\u00b3\/h pump. The compact entry unit.<\/li>\n
- EVT-7-C \/ TD<\/strong> \u2014 chamber 430\u00d7440\u00d7205 mm, 20\/21 m\u00b3\/h pump, double sealing bar, TD version with gas injection.<\/li>\n
- EVT-10-C \/ TD<\/strong> \u2014 chamber 530\u00d7432\u00d7205 mm, 20\/21 m\u00b3\/h pump, with 1 or 2 sealing bars.<\/li>\n
- EVT-28<\/strong> \u2014 chamber 916\u00d7432\u00d7180 mm, two 20\/21 m\u00b3\/h pumps and a double bar: a tabletop built for long pieces.<\/li>\n<\/ul>\n
Note the EVT-28 detail: it shows that “tabletop” doesn’t mean “for small pieces”. You choose the format by space; the chamber, by what you pack.<\/p>\n
The floor unit (single chamber): more chamber and more pump<\/h2>\n
When volume rises or pieces are large, you move to the floor-standing single chamber. Same chamber principle, but with more capacity and larger pumps, sized to pull the vacuum in that bigger chamber. See the detail on the chamber range product sheet<\/a>.<\/p>\nReal examples from the range:<\/p>\n
\n- EV-15<\/strong> \u2014 chamber 530\u00d7432\u00d7205 mm, 20\/40 m\u00b3\/h pump. Compact, but already a floor unit.<\/li>\n
- EV-13<\/strong> \u2014 chamber 795\u00d7535\u00d7200 mm, 63\/100 m\u00b3\/h pump, with gas as standard.<\/li>\n
- EV-25<\/strong> \u2014 chamber 1118\u00d7715\u00d7218 mm, 100\/150 m\u00b3\/h pump. Large format.<\/li>\n
- EV-29<\/strong> \u2014 chamber 1180\u00d7725\u00d7220 mm, 100\/150 m\u00b3\/h pump. The maximum single-chamber capacity.<\/li>\n<\/ul>\n
Here we’re no longer talking about a jump in “vacuum quality”, but about how much you pack per cycle.<\/p>\n
The double chamber: when the bottleneck is time<\/h2>\n<\/div>![\"Tecnotrip](\"https:\/\/www.tecnotrip.com\/wp-content\/uploads\/2026\/10\/envasadora-vacio-doble-campana-1.webp\" "\\"envasadora-vacio-doble-campana\\"")
<\/span><\/div>The double chamber is the next step when the problem stops being the chamber and becomes the clock. It has two chambers: while one draws vacuum and seals, the operator is already loading the other. The result is a much higher cadence with nobody waiting for the cycle.<\/p>\n
Examples from the range:<\/p>\n
\n- EVD-22<\/strong> \u2014 2\u00d7 chamber 640\u00d7615\u00d7195 mm, 100 m\u00b3\/h pump. The entry to double chamber.<\/li>\n
- EVD-16<\/strong> \u2014 2\u00d7 chamber 820\u00d7825\u00d7225 mm, 150\/250 m\u00b3\/h pump. High cadence.<\/li>\n
- EVD-19<\/strong> \u2014 2\u00d7 chamber 955\u00d7895\u00d7250 mm, 250 m\u00b3\/h pump, with optional automatic lid.<\/li>\n
- EVD-19-11<\/strong> \u2014 2\u00d7 chamber 1255\u00d7925\u00d7245 mm, 300 m\u00b3\/h pump. Large format.<\/li>\n<\/ul>\n
It’s the natural option for meat, fish or ready-meal industries with sustained volume. And above it, the automatic range (loading and unloading without an operator at the chamber) for continuous production.<\/p>\n

What changes is chamber size and cadence.<\/p>\n
So which one do I need?<\/h2>\n
Five questions and the decision clears up on its own:<\/p>\n
\n- What pieces do you pack, and how big?<\/strong> This sets the minimum chamber you need.<\/li>\n
- How many packs per day, and at peak?<\/strong> Low \u2192 tabletop; medium-high \u2192 floor; high cadence \u2192 double chamber.<\/li>\n
- Do you have fixed space or need a countertop machine?<\/strong> This decides between tabletop and floor.<\/li>\n
- Do you need gas injection (modified atmosphere)?<\/strong> Available on several models; confirmed by reference.<\/li>\n
- Do you expect to grow?<\/strong> If you’re scaling up, it’s worth sizing the pump and cadence with some margin.<\/li>\n<\/ul>\n
None of these questions is about “vacuum quality”, because that’s the same across the range. They’re about capacity. Which is exactly why it’s best to check them with technical advice.<\/p>\n
The factor that isn’t on the spec sheet: reliability and service<\/h2>\n
Choosing a format is the first step. The second, just as important, is who you buy the machine from. A stopped machine isn’t a technical problem: it’s a day you can’t pack and product that deteriorates.<\/p>\n
So, beyond the format, it’s worth looking at robust build and longevity \u2014machines that withstand daily use for years\u2014, after-sales service and factory-direct spare parts, and a manufacturer that knows the product and helps you size it right first time. That’s the approach Tecnotrip builds its sealers with in Terrassa: mechanical and electrical reliability, simple maintenance and direct spares, with machines still in service after more than 25 years.<\/p>\n
Summary<\/h2>\n
The right question isn’t “chamber or tabletop?”, because at Tecnotrip the whole vacuum range is chamber-based. The tabletop pulls the same vacuum as the floor unit: what changes is format and capacity. Choose by the size of your pieces, your volume, your space and your cadence \u2014not by a supposed jump in vacuum quality that doesn’t exist\u2014 and validate the figures with data.<\/p>\n
Frequently asked questions<\/h2>\nDoes a tabletop vacuum sealer pull less vacuum than a big one?<\/h3>\n
No. At Tecnotrip the tabletop is a chamber machine, just like the floor unit, and reaches the same type of vacuum. What changes is the chamber size \u2014and the pump, which is sized to that volume\u2014, not the vacuum quality.<\/p>\n
Can I pack liquids with a tabletop sealer?<\/h3>\n
Yes, as long as it’s a chamber machine (like the Tecnotrip range), because the vacuum is created in the chamber and not by suction from the bag. The difference versus a floor unit is capacity, not suitability for liquids.<\/p>\n
When do I move up to the double chamber?<\/h3>\n
When the bottleneck is time, not chamber size. If you need more packs per shift and the operator waits for the cycle, the double chamber loads one chamber while the other seals.<\/p>\n
