Features

24 hours continuous operation possible Compact, high-performance

We have redeveloped the inner part of the fan motor and its control to realize the company`s vision of “compact high performance”.
Compared to competing products, our product has a 50% lower volume ratio, and is a successful example of the miniaturization of high demand devices in recent years. Operating efficiency is the same at 50Hz/60Hz.

Product structure and features

1. Primary filter

Filter bag is made of five layers of nonwoven polypropylene fabric.
The five layers have different air permeation rates to minimize clogging and provide a filtration rate of 95%or higher for particulates of 45μ and larger. The five layer filter also offers high overall strength;thus, it does not tear easily unlike a paper pack.

2. Secondary filter

Nonwoven polypropylene fabric is formed into a pleated filter. The outside frame is molded in ABS resin
(CKU-240AT3-HC is polypropylene). Highly effective with a filtration rate of 99% or higher for particulates of 0.3 μ .

CKU series (with filter cases open)

3. Exhaust filter

This uses the same filter as the secondary filter, and collects particles that were not extracted by the primary and secondary filters. Also, it is installed for the purpose of collecting dust particles generated in the fan motor chamber. The filter has a filtration rate of 99% or higher for particulates of 0.3 μ, thus enabling the use of the dust collector for applications requiring cleanliness class of 100,000 to 10,000. If a HEPA filter (filtration rate of 99.97% or higher for 0.3 μ particulates) is fitted, the dust collector complies with cleanliness class 1,000 to 100. Note:Based on factory inspection data.

For the CKU/CBA series, if the model number has V1 at the end, a HEPA filter is installed as standard equipment.
Standard specification models can be easily converted to V1 specification after purchase. (CKU-240AT3-HC requires replacement of the exhaust cover).
