Buying a used vacmaster chamber vacuum sealer is probably the smartest move you can make if you're tired of those flimsy suction-style kitchen sealers that struggle with a single drop of moisture. If you've spent any time looking at new ones, you know the price tag can be a bit of a gut punch. They are heavy, professional-grade machines that usually cost anywhere from six hundred to over a thousand dollars. But because they are built like absolute tanks, picking one up second-hand is often a fantastic way to get a "buy it for life" tool without the "buy it for life" price.
I've spent a lot of time around these machines, and honestly, once you go chamber, you never go back. But there are a few things you really need to look out for when you're browsing Facebook Marketplace or eBay for a used unit. It's not quite the same as buying a used toaster; there are pumps, gaskets, and oil levels to consider.
Why Everyone Wants a Chamber Sealer
If you're currently using a suction sealer—the kind where the bag stays outside the machine—you know the struggle. You try to seal a bag of marinated chicken, and the machine sucks the liquid right into the motor, ruining the seal and potentially the machine.
A chamber sealer works differently. You put the whole bag inside the machine and close the lid. The machine removes the air from the entire chamber, so the pressure inside and outside the bag remains equal. This means you can vacuum seal a bag of pure water if you want to. For anyone who likes sous vide cooking, bulk meat processing, or just wants to save leftovers without freezer burn, it's the gold standard.
Finding the Right Model: VP215 vs. VP210
When you're looking for a used vacmaster chamber vacuum sealer, you'll likely see two main models popping up: the VP210 and the VP215. At first glance, they look identical, but the internals are very different.
The VP210 uses a "dry" pump. This means it's maintenance-free because there's no oil to change. It's a great machine for a home cook who doesn't want to mess around with mechanics. However, these pumps can run a bit hotter and might not be quite as durable over 20 years as their oil-based cousins.
The VP215, on the other hand, is the one most pros and serious enthusiasts hunt for. It has a rotary oil pump. This thing is a workhorse. It runs quieter and can handle back-to-back sealing all day long without breaking a sweat. If you find a used VP215, you're getting a professional piece of equipment. The only catch is that you have to change the oil every now and then, but that's a small price to pay for a machine that will likely outlive you.
What to Inspect Before Handing Over Your Cash
If you find a local listing for a used vacmaster chamber vacuum sealer, don't just grab it and go. You want to test it out. These machines are heavy—usually around 60 to 80 pounds—so you don't want to get it home only to realize it has a leak.
First, check the lid gasket. Look at the rubber seal that goes around the rim of the lid. It should be soft and pliable, not cracked or brittle. If it's damaged, it won't hold a vacuum. Luckily, these are cheap and easy to replace, but you can use it as a bargaining chip.
Next, look at the seal bar. This is the element that actually melts the bag shut. Peel back the brown Teflon tape slightly if the owner lets you. The heating wire underneath should be straight and clean. If the tape is burnt or the wire looks fried, it's been used heavily. Again, these are replaceable parts, but they give you a clue about how the machine was treated.
The most important thing to check on an oil-pump model is the oil level and clarity. There's a little sight glass on the back or side. If the oil is milky or dark brown, it hasn't been changed in a long time. Clear or light yellow oil is a sign of a well-maintained machine.
The Secret Benefit: Drastically Cheaper Bags
One of the biggest reasons to hunt down a used vacmaster chamber vacuum sealer is the long-term savings on bags. If you use a FoodSaver, you know those textured bags are expensive—sometimes 50 cents to a dollar per bag.
Chamber sealers use "barrier bags," which are smooth and incredibly cheap. You can usually get them for about 5 to 7 cents each. If you seal a lot of food, the machine literally pays for itself within a year or two just in bag savings. I've found that even if I paid a bit more for a used unit, I'm still saving money every time I seal a steak or a batch of soup.
Common Issues You Might Encounter
It's rare for a Vacmaster to just "die," but they can have hiccups. Sometimes a used machine won't pull a full vacuum. Usually, this isn't a broken motor; it's a simple air leak. It could be the gasket, or it could be that the lid needs a slight adjustment.
Another common thing is the "piston" that raises the seal bar. If it feels sluggish, it might just need a bit of cleaning. These machines are surprisingly "analog" in a way—they are mechanical and logical. If you're even a little bit handy, you can fix almost anything on them using parts ordered directly from the manufacturer's website.
Where to Look for the Best Deals
Don't just stick to the obvious places. Sure, check the local classifieds, but also keep an eye on restaurant liquidation auctions. Restaurants close down all the time, and they often have a used vacmaster chamber vacuum sealer sitting in the prep area. You can sometimes snag these for a fraction of their retail value because the auction bidders are focused on the big ovens and refrigerators.
Also, check hunting and fishing forums. Hunters are big fans of these machines for processing venison or elk, and sometimes they upgrade to even larger industrial units and sell their older Vacmasters for a decent price.
Maintenance Tips for Longevity
Once you get your machine home, give it some love. If it's an oil pump model, change the oil immediately. You don't know how long it's been sitting there. Vacmaster sells specific oil for this, and the process is as simple as draining a lawnmower.
Keep the chamber clean. If you spill some soup or juice inside, wipe it up right away. Moisture is the enemy of the pump, so if you're sealing something particularly wet, it's a good idea to run a "warm-up" cycle afterwards to help evaporate any moisture that might have been sucked into the oil.
Is It Really Worth the Hassle?
You might be wondering if it's just easier to buy a cheap $100 suction sealer from a big-box store. If you only seal one bag of frozen peas every three months, then yes, stay with the cheap one. But if you're someone who buys meat in bulk, meal preps for the week, or enjoys the precision of sous vide cooking, a used vacmaster chamber vacuum sealer is a total life-changer.
The quality of the seal is just better. You get a much higher vacuum pressure, which means the food stays fresh significantly longer. No more freezer burn ruining an expensive ribeye. Plus, there is something deeply satisfying about watching the machine work through that heavy acrylic lid. It feels like a piece of industrial equipment because it is.
In the end, these machines are built for the long haul. Buying used isn't just a way to save money; it's a way to get professional-level technology into your home kitchen. Just do your homework, check the gaskets, and make sure the pump sounds smooth. You'll likely be using that machine for the next decade or two.
