Matsui – DMD4


DMD4 is a dehumidifying dryer and a suction loader that supplies stable dew point dry air for optical moulding combined in a single unit. As it is unnecessary to replace the absorbent material, performance is being maintained like that of first usage.

1. Reliable

Uses a heat-resistance drying filter (0.3μm/99.97%) to clean the heated air just before it’s delivered into the hopper. Matsui’s original push gate prevents contamination that occurs due to friction of the gate.

2.Removes dust residue

Matsui’s original Aero Power Hopper conveys the material while at the same time removing any material dust, greatly reducing problems such as “black spots”.

3.Easy Maintenance

The need for maintenance of filter is greatly reduced as dust is removed in the cyclone separator. The manual butterfly valve allows maintenance to be carried out even during the drying process.


Heater control circuits are equipped with SSR (non-contact relay), which is safer and reduces the need for maintenance.
