rotex 150加CT集尘使用很久了 其实CTL系列的L还不算是过滤级别最高的 CTM的标准更高一些 一些M级高端型号都 ...
$ i+ q4 e) L7 c) C$ z8 }( P ?, R6 JThere is NO difference between the filtering capacity of the CTL and the CTM. Only difference is that the CTM has an extra circuit monitoring the air flow through the hose, giving off a warning signal when the airflow suddenly drops. Most of the time that means it's time to change the bag8 e" Q9 \$ r/ R. N

6 E+ h r' i8 W( m) x( U) g$ fAccording to those specifications, the CTM provides better filtration for fine dust applications such as concrete. The question is, how is the better filtration achieved? Both the CTL 26 and CTM 26 use the same filter (496171) and the same bags (496187).

Basically, in terms of the level of extraction, there is no difference between the CTL and CTM extractors. They both have the same motors, same filters, same bags. Both are equally good for wood dust extraction.* c7 @( s- m& j1 y

The only difference is that the CTM has a sensor & circuitry that provides a warning if the airflow through the inlet falls below a certain level. You only need that if, for some reason, you need to absolutely guarantee that the suction doesn't drop off (due to a full bag, blockage etc) without you knowing about it. Chances are, even without that warning, you'd know if there was a problem!

; Q( j8 H# @7 r. fThe CTL is approved for dust category L; the CTM is approved for dust category M. Having the warning sensor is, presumably, a pre-requisite for approval for category M, but since the components are the same the CTL must therefore also be suitable for dust category M, it just can't be approved for it.0 r- h, i3 d7 P, D3 N' _

用旋风桶也基本上都是为了省清理滤袋的，毕竟大颗粒木屑甚至木片更容易塞满滤袋。细微颗粒堵滤袋的话基本只能换滤袋了。) [' [9 b6 r% V# D1 Z s% X
