Flameproof Agitator Ex Series
Ex300/Ex600/Ex1200/Ex2000/Ex3000

The Three-One Motor Ex is the first motor-driven, flameproof enclosure agitator in the Three-One Motor series. Built on years of usability know-how, its compact body achieves the same ease of use as standard models while meeting flameproof requirements, making it ready for direct laboratory use.

Equipped with a large interlocked safety cover for enhanced safety.

* The large interlocked safety cover is included as standard with units shipped after the recent price revision.

Power supply: 100 V AC only. The flameproof enclosure certification is valid only in Japan.
