3 Description
3.1 Function
FlexPAK is a complete vacuum unit for use in non-EX
applications with a direct driven side channel fan fit-
ted as one unit on a steel frame and a start and con-
trol unit with an integrated 24 V transformer. The unit
is controlled by a frequency converter, has automatic
start/stop, and automatic filter cleaning.
3.1.1 Filtration in two stages
FlexPAK filters particles in two stages. In the first
stage, coarse particles are separated away in the inlet.
In the second stage, fine particles are separated away
by filter bags, see Figure 9.
3.1.2 Automatic filter cleaning
FlexPAK uses filter cleaning by a short blast of re-
versed airflow with atmospheric pressure. By the rap-
id opening of the Filter Cleaning Valve (FCV) located
on top of the filter, a powerful blast of reversed air-
flow is created, efficiently dislodging dust from the fil-
ter bags, see Figure 8.
