Manufactured primarily for textile processing. Designed to capture both lint and dust. Reducing the volume of dust handled by downstream primary filters.
The Nederman Pneumafil Rotary Pre-filter
is designed to capture both lint and dust. It
is installed upstream of primary dust filters
and is particularly suitable for large tunnel
The unit features a disk-shaped screen
which rotates in a vertical plane. Lint and
dust accumulates on the screen and is
removed by a reciprocating suction arm,
operating continuously or upon demand, as
required by the application.
In the continuous mode, the pre-filter
functions similarly to a pre-separator,
removing lint and large clumps which
would overload or clog the primary filter.
In the more customary demand mode,
operation is triggered by pressure drop
caused by the build-up of lint and dust
on the screen.
As the screen captures
material, the resultant mat acts as filter
media, capturing fine dust as well as lint.
Only a small portion of the mat is removed
at any given time, which helps maintain a
constant level of filtration efficiency.
When used as a pre-filter, the unit reduces
the volume of dust that must be handled
by downstream primary filters. The result
is greater overall system efficiency and, in
some cases, reduced investment for
