RF Baghouse, Models RFT, RFW, and RFWH
2
Description
The RF Baghouse is a continuous duty dust collector
with bag-style filters designed to handle applications
with heavy dust loads. Continuous-duty means the filters
can be pulse cleaned on-line without interrupting airflow
through the collector. A timer energizes the cleaning
system to ensure the bag-style filters are cleaned at
least once every four minutes.
The cylindrical collectors housing design features an
all-welded or an optional bolt-together construction in
standard sizes from 48 to 484 filter bags with either 8,
10, or 12-ft long bag-style filters. The collector housing
design can include an involute scroll inlet or an upper
body radial high inlet.
The involute inlets are typically used for heavy non-
abrasive dust loading applications. These inlet styles
allow the majority of the incoming dust to cyclonically
separate. The heavier dust separated in these inlets is
directed downward into the hopper while the lighter
dust is passed through air straightening veins to evenly
distribute the air and entrained dusts over the filter bags
for final separation.
The upper body radial style high inlet is typically used on
lower density dust type applications. This style of inlet is
located in the filter housing section below the tubesheet,
and directs the incoming dust particles downward
around the filter bags and into the hopper. This flow path
assists the cleaning system by supporting an airflow
pattern that encourages the dislodged dust pulsed off the
filter bags to move downward into the hopper. Baffles in
the inlet keep dusts from directly impinging on the filter
tubes.
The RF Baghouse is available in two different access
styles. RFT models which allow walk-on, top-access bag
removal, and RFW / RFWH models which feature a walk-
in clean-air plenum. All models allow filter-bag service
from the clean-air side of the collector.
