RPJ Bag Filter
Collects the product out of the air stream. Cleaned on line, so the plant does not stop for the filter.
Specification
Every figure, and where it comes from.
Values are taken from the company's own technical specification and cross-checked against its quotations. Where two documents disagree, both readings and the rule applied are stated in the row.

The drawing
How it is built, and how it moves.
Drawn on the same drafting system as the rest of the set: five stroke weights by role, a 2 px grid, and motion derived from the machine's own kinematics rather than approximated.
How it works
The principle behind the specification.
On-line cleaning
Dust-laden air enters below the tube sheet and passes through caged bags from outside to inside, leaving a cake on the outer surface. A diaphragm valve fires a short blast of compressed air down the inside of a row of bags; the shock sheds the cake, which falls to the hopper. Only one row is off duty at a time, so filtration never stops — that is what 'on line' means and it is why the plant does not need a second filter to switch to.
