MBM provides a one year warranty on this product

One of MBM's top paper folders is the 352S
Professional Series Air Suction Paper Folder. This is one of the best
devices for speed and precision performance. The all steel construction
is robust enough to stand up to the heavy duty use needed in quick
print shops, copy shops, and digital printing environments. The
following is a closer look at the 352S.

Strengths:

• An air suction feed system differs from the standard
  friction feed found on most paper folders. Polyurethane foam rollers
  eradicate the need for roller pressure settings and automatically
  compensate for changes in paper thickness. An anti-static strip smooths
  the way for use in high static environments as well as allowing
  carbonless paper through the machine. The low-maintenance turbine
  blower is completely enclosed for quieter operation and doesn't require
  filter changes.
• The fold plates automatically adjust within
  seconds for both standard and customized folds. Dual fold plates are
  pre-programmed to create double parallel, letter, "Z", single, foldout,
  and right angle folds. You can also setup a wide variety of custom
  folds depending on your needs.
• A unique feed system allows
  continuous reloading as well as reliable sheet separation. Paper is
  inserted on the top of the tray while the rollers pull from the bottom.
  Up to 450 sheets can sit in the hopper at once and fold as fast as
  30,000 sheets per hour! Variable speed control allows you to select a
  faster or slower speed if needed. Folded documents exit via powered
  conveyor belt.
• Paper is accepted in a broad spectrum of sizes
  and weights. Items as small as 3-3/8" x 4-3/4" can fold as well as
  12-5/8" x 17-3/4" and everything in between. Weights ranging from 13lb
  to 110lb bond are also able to be folded. The air feed system allows
  both glossy and coated stocks to go through the fold plates.
• MBM provides a one year warranty on this product, excluding wearables.

Weaknesses

• Weighing 312 pounds, this is a hefty piece of office
  equipment. However, it comes with a stand mounted on casters for easy
  mobility. We think most users won't have an issue with this.
• One
  thing this folder is lacking is a counter. Counters provide the
  benefit of keeping track of folded items as well as offering batch
  folding. Depending on your needs, this may or may not be a problem.
  The Formax FD390 is a comparable machine that includes a counter.
• Another
  feature that would be nice is the option for multi-sheet combined
  folding. Again, many users don't need this option. But if your company
  often folds multi-page newsletters or invoices, you may want to
  consider a machine with this capability, such as the Martin Yale 2501
  Smartfold.

As evidenced by the many strengths, the 352S
is ideal for a wide variety of businesses. Professional print and copy
shops will especially appreciate the ability to fold coated and glossy
materials. Simple use, functional design, and high speeds contribute to
the convenience and efficiency of this device. We highly recommend
this excellent machine for your next high volume paper folder.
