What to know before you buy

Largest pouch: The maker's own page disagrees with itself on the largest pouch: one place gives 10 x 13 in, while the pouches in the box are 11 x 10 in outside with a 10.5 in opening. We do not pick one. Until the maker settles it, a pouch that fits within both figures is the safe choice.
Chamber: The usable chamber is 12 in × 11 in × 8.5 in: tall enough for bone-in cuts and jars that have to clear a closed lid.
Upkeep: The maker publishes a dry pump: there is no pump oil to buy, check or change.
Where it lives: At 26.3 lb it can come out of a cupboard and back again.
Pouches that fit: These chamber pouches in the catalogue fit its sealing width and are no longer than the 10 in maximum pouch length its maker states:
Breville Commercial PSC-VBF-0610 Chamber Vacuum Bags, 6 × 10 in, 250-count
Avid Armor ACPAX1 Chamber Pouches, 300-count assorted
LEM MaxVac Pro Chamber Pouches, 6 × 9 in, 250-count
