5.1 Function
E-PAK 150 DX/300 DX/500 DX has been designed to lter combustible and
non-combustible dust in a high vacuum system.
E-PAK 150 DX/300 DX/500 DX is a complete vacuum unit with a direct-
driven side channel fan tted as one unit on a steel frame and a start and
control unit with an integrated 24 V transformer. E-PAK 150 DX is direct
started, while E-PAK 300 DX/500 DX are Y/D started. The unit has automatic
start/stop and automatic lter cleaning in two stages.
Filtration in two stages
In the rst stage, the inlet separates course particles. In the second stage, ne
particles are separated on conductive lter bags.
Automatic lter cleaning
E-PAK 150 DX/300 DX/500 DX uses lter cleaning by a short blast of reversed
air ow with atmospheric pressure. By the rapid opening of the lter cleaning
valve located on top of the lter, a powerful blast of reversed air ow is
created, efciently dislodging dust from the lter bags.
Figure 4 shows the function of E-PAK 150 DX/300 DX/500 DX according to
the following:
1. Air ow during normal operation and collection of dust.
2. Air with atmospheric pressure released into the lter during lter cleaning.
3. Short blast of reversed air ow during lter cleaning.
4. Filter cleaning valve.
