HSM SECURIO P36i 3/16 x 1 1/8 Cross Cut Document Shredder - HSM1853

The HSM SECURIO P36i HSM1853 is a floor-standing cross-cut shredder that cuts paper into 3/16 x 1 1/8 in (4.5 x 30 mm) particles, security level P-4, and accepts 27-29 sheets per pass. It pairs a 1,000 W motor with an integrated automatic oiler and a 38.3-gallon (145-liter) bin. For a department that handles personnel, customer or financial paperwork every day, it is the default choice in the P36i family.

What P-4 means for the paper you feed it

DIN 66399 sets a maximum particle area for each class. At P-4 that ceiling is 160 mm², and the HSM1853 cuts 135 mm², so it sits inside the class with margin. In practice P-4 is what most privacy programs and audit checklists name for documents carrying names, addresses, salaries or account numbers. Its complete rating is E-3, F-1, O-3, P-4, T-4. Classified material and contracts that call for P-5 or above need a finer machine.

The oiler and other details that keep the HSM1853 running

A cross-cut head has far more cutting edges than a strip-cut one, and those edges lose capacity if they run dry. The P36i HSM1853 lubricates itself through its integrated oiler, which strip-cut versions of the cabinet do not have. HSM rates the motor for continuous operation and publishes no cool-down period, so a long clear-out does not have to be broken into sessions.

Feeding is hands-off: the rollers start when paper arrives and stop when it clears, an overfed stack is detected and reversed before it jams, and a safety element across the 12.99 in (330 mm) opening stops the intake under light pressure. Tabloid, legal and A3 sheets fit without folding. Waste collects in a reusable corrugated insert rather than plastic sacks; order HSM1850BOX when it needs replacing. Idle noise is about 55 dB(A), and standby draw drops to 0.1 W.

HSM1853 versus its closest siblings

• P40i 4.5 x 30 mm (HSM1883): the identical P-4 particle with a 1,300 W motor and 34-36 sheets per pass, for floors where several departments share one machine.
• P36i 4.5 x 30 mm with CD unit (1853121C): adds a separate 4 x 7 mm cutter for discs and cards, raising the media rating to O-4 and T-5.
• P36i 1.9 x 15 mm (HSM1852): steps up to P-5 at 16-18 sheets when a policy names that class.

Is the HSM1853 the right fit?

Yes, if you are replacing a small deskside shredder that an audit flagged, or a team of colleagues needs one dependable P-4 machine that will not overheat on a busy afternoon. Look elsewhere if CDs and DVDs are a regular part of the job, since HSM rates this head for paper and credit cards only, or if your paper falls under a P-5, P-6 or P-7 requirement. At 150 lb (68 kg) it ships on a pallet, so arrange two people for the move into place.
