The WP baghouse filter is built for large industrial dust
collection applications and requires a support structure. This filter is a
primary dust collector with bag section on top which uses reverse air for
cleaning of the bags. Dust is pulled from inside the bags and blown back into
the cyclone section at the bottom of the primary filter.

A complete dust collection system will improve indoor air
quality by removing dust from a series of work stations, machines and tools.
Furthermore, one large centrally ducted dust collection system addresses the
need for using an industrial air cleaner on each workstation.
One large central dust collector system can often do the
work of dozens of smaller, individual air cleaners, providing complete
industrial plant dust collection for the entire facility.
Central dust collection systems generally consist of
large media dust collectors (such as cartridges or bag houses) with an inertial
separator used as a pre-sorter (such as a cyclone or drop out box). The
pre-sorter removes large chips, and then the media filtration removes fine
particles. Large chips are collected in bins or drums.
Filtration media often uses some form of cleaning such as
mechanical shaking or a sudden pulse of air that knocks built up dust cake from
the filters. Electrostatic precipitators are rarely used for large dust
collectors, since they do not have the capacity to store a large volume of
dust. Though, electrostatic air cleaners are frequently used alongside central
systems to clean atmospheric background dust that is not captured by the ducted
system.
Waste Removal: As dusty air is filtered, waste dust is
collected in bines, drawers or hoppers. Waste removal from one location verses
many locations is easier and thus more cost effective.
Equipment Cost: Often the deciding factor when choosing a
dust collection solution. Depending on the cost of ductwork and installation, a
central dust collection system can initially cost less than purchasing 12 or
more individual dust collectors.
Filter Replacement: Replacing filters from 12 or more
separate machines will cost more than regular filter replacement of one large
dust collector designed for heavy loads.
Energy Consumption: Your energy bill will be lower when
powering one big dust collector than if you try to power a dozen or so dust
collector motors.
Noise: Imagine the noise from 12 or more dust collector
motors and blowers running in a work area. Now take that noise, put it all in
one big motor / blower and tuck it away in its own area, away from workers.
Maintenance: You can go either way on maintenance. With
multiple air cleaners, you have that many more parts to replace. With one
central dust collector, you only have one set of components to maintain. On the
other hand, if your central dust collection system goes down, all workstations
go down.
