Description
The RFWP Baghouse is a continuous duty dust collector with
bag-style filters designed to handle up to
141,000 cfm depending on the application and dust type.
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 a sectional
bolt together construction in standard sizes from 570 to 905
filter bags with either 10 or 12-ft long bag-style filters. The
collector housing design can include an involute, scroll-type
inlet with an internal deflection baffle or a high body inlet.
The involute inlet removes heavy materials before they
reach the bags, eliminating the need for a separate cyclone
precleaner. The high body inlet is ideal for lighter density
materials and may offer better abrasion resistance.
The RFWP features a walk-in clean-air plenum, allowing filter
bag service from inside the clean air plenum.
The RFWP Baghouse collector is common in the woodworking
and grain industries where it effectively handles high-volume,
high dust-load applications. Additional applications include
cement, chemical, coal, and food processing applications like
sugar and other moisture-sensitive materials.
These RFWPs are typically used in applications over 37,000
cfm.
Sizes are available for applications with any of the following
conditions or requirements:
• Heavy dust load
• No compressed air available
• A round collector required for sanitary reasons
• High pressure or vacuum requirement
• A requirement for a single discharge hopper
Operations involving higher temperatures, humidity, or air
stream chemistry may require special attention. These
conditions can usually be supported with custom design
modifications to the RFWP Baghouse collectors.
Purpose and Intended Use
Misuse or modification may result
in severe personal injury and/or
property damage.
Do not misuse or modify.
