However, it must be noted that the use of a flameless device does not eliminate the risk area. The
high pressure and hot gases are still released into the surroundings, and this must be taken into
consideration when positioning the FlexPAK 800/1000 DX. Please consult your local fire authority
when determining suitable positioning of the FlexPAK 800/1000 DX with flameless device.
Please refer to the installation and service or user manual for the flameless device supplied with the
FlexPAK 800/1000 DX to find other limitations and information regarding safe use and service.
The use of a flameless device will also reduce the venting efficiency of the FlexPAK 800/1000 DX.
This means that the FlexPAK 800/1000 DX will not be able to be used with explosive dust types
with a higher Kst (ST type). The limit of the Kst value (ST–type) is determined by the parameters
of the specific flameless device.

Isolation device

An isolation device, see figure 9, item 2, is to be installed to prevent a filter explosion from
propagating back into the plant through the connected duct. The duct, see figure 9, item 3, between
the unit and the isolation device is to be pressure-resistant to an overpressure of at least 0.5 bar
(7.2 PSI) and have a minimum length as specified in the manual of the isolation device. This is
normally 4 meters for ST2 and 2 meters for ST1.
