3.0 Machine overview
3.1. Description
GFB2 Tower is a filter unit that is used for different fil-
tering needs. The product contains filter media, which
must be selected according to the specific filtration need.
3.2 Intended use
The GFB2 Tower is used to filter the extracted air from
industrial processes such at welding, grinding, sandbla-
sting, and powder coating.
The filter is not to be used in areas categorised as ATEX
zones, e.g. with dust from aluminium, flour, wood, and
other mediums that present an explosion hazard.
The GFB2 is supplied with filter cartridges of various ple-
ated textiles, both with and without coating.
The filter self-cleans automatically as a compressed air
pulse is sent down through the filter cartridges, causing
the particles on the filter to be blown off and collected in
the bucket below.
Particle catch in the inlet functions as a diffusor and ca-
tches large particles, that could otherwise damage the
filter cartridges.
The GFB2 Tower has a fan installed on top.
3.3 Machine specifications

Differential pressure drop
Typical pressure drop: 1.000-1.500 Pa
The pressure drop in the filter will vary depending on
the load and how dirty the filter cartridges are. The
filter cartridges must be replaced, when the pressure
drop exceeds 2.000 Pa.
Differential pressure drop is NOT allowed exceed 3.000 Pa.
Particle catch in the inlet functions as a diffusor and
catches large particles, that could otherwise damage the
filter medium.

The particles fall into the bucket at the bottom of the fil-
ter.

4.0 Transport, handling and storage
During transport in a truck or in another means of trans-
portation the product must be securely packed in a box
or a pallet and covered with a water proff material.
The product must be securely stowed in the truck so that
it will neither tilt nor shift during transport.
During transport over a short distance e.g. in a stock or
a factory, the product can be moved by means of a forklift
or a stabeler.
When moved it must be secured that the product does
not tilt or shift. And it must be secured that the limitations
of the means of transportation is not exceeded.
Secure that there are no people around the product,
when the product is moved.
The product must be placed in a dry place and covered
securely, in order to secure that moist, metal parts or
other substances do not damage the product.

5.0 Assembly, installation and start of
operation
5.1 Location
For error-free performance, the product should be in-
stalled indoors, e.g. in a well-ventilated room. We do not
recommend outdoor installation. If indoors installation is
not possible, the product must at least be installed under
a roof.
We do not recommend placing the filter outside, as it
may cause condensation, and some of the electronic
components may cease to function at temperatures
below -10°C.
Before installing the product, please make sure that
the optimum installation area is selected. Is there room
enough for the filter indoors? Is there space enough for
carrying out satisfactory installation/-service of the filter?
Place the product upon a solid, flat foundation (e.g. a
concrete floor) and anchor it.
5.2 Installation
