Structure and characteristics of particle collection

24-hour continuous operation possible, compact and high performance

In order to realize our concept of “small size and high performance”, we have newly developed the fan motor at the heart and its control. Compared to other companies’ equivalent products, we have achieved a 50% reduction in volume. We will contribute to the miniaturization of equipment, which has been highly requested in recent years. Of course, both 50Hz / 60Hz can be used with the same performance.

(1) Detachable flange

The size of the suction port flange can be replaced with a single touch.

(2) Pre-filter (primary filter)

Due to the special structure, the collision-buffered dust becomes large particles and is collected by the primary filter. The material used in the primary filter is polypropylene pleated and cassette type. A disposable type that can be easily replaced.

(3) Activated carbon filter (secondary filter)

Fine particles that are not collected by the primary filter collide with each other as they pass through the granular activated carbon and are collected. At this time, the odor is also adsorbed at the same time.

(4) High-performance filter (third-order filter)

It collects fine dust from the activated carbon filter to purify the air and exhaust it. The high-performance filter catches the particles that were not collected by the secondary filter. The invasion of activated carbon particles into the blower side is also prevented here.


Control (accessories sold separately)

Remote control

By using a remote cable (sold separately / model: MT-173-8 (3m)), remote control linked with peripheral devices is possible.

  • Driving ON / OFF
  • Ability level (air volume) change

You can now change the ability level by remote control. Since the level is memorized every time the ability level is changed, the previous usage level is always called. In addition, it is possible to output operation signals, filter clogging signals, pressure signals, and abnormal signals.

Ethernet / RS-485

All functions that can be controlled by the AT3 panel can be controlled by a PC by using Ethernet or RS-485 communication.

Easy attachment / detachment flange (standard: φ65) (sold separately)

  • Can be replaced with one touch
  • The suction port size can be changed

The size of the suction port flange can be replaced with a single touch.
The suction port flange (sold separately) can now be changed even after purchase.

Required air volume calculation formula

Q: Required air volume (m3 / min)
Vc: Control air speed (m / sec) ・ ・ ・ ・ See the figure below
X: Distance (m) ・・ ・ ・ ・ ・ ・ ・Distance from dust source to suction port
A: Opening surface Area (m2) ・ ・ ・ L × W
Air volume Q = 60 x Vc x (10 x X² + A)





* 1 This is a value measured with A scale (dBA) at any point 1 m away from the main body by connecting a hose to the suction port.

* 2 An optional remote cable is required to use the remote control function.

* 3 Optional support is available.
