FFU fan filter

Mounted on top of the machine. A motor turns the air through a filter, and positive pressure keeps dust out.

How it works

The FFU sits on top of the machine. A motor wheel turns the air, the filter cleans it, and positive pressure keeps outside dust out.

Dust count, cumulative over 1 minute

After installation, dust fell sharply.

Particle size	Without FFU	With FFU
0.3 μm	466,984	51,377
0.5 μm	35,695	2,975

Dust figures are before-and-after test results, not a guarantee.

Setup

Only a power supply is needed: single-phase AC 220 V / 50 Hz / 100 W. Other power specs can be matched when noted. The machine maker, model, and details are checked first, then the mounting plate is designed, made, and fitted. Installation is about 20 minutes per unit.
