Dust Collection Balancing
Dust Collection Balancing
(OP)
Hi
I am new to the forum and need some help.
Basically we are trying to construct a test rig for a dust collection system and need to install approx 3000 Pa pressure drop into the rig.
The airflows are
78l/s and 130l/s.
Does anyone know what we can install to replicate the pressure loss?

A bag with the right amount of dust in it.

If you are balancing, then you need a manually adjustable valve with a predictable flow characteristic. Pinch valves are typically air-operated and normally for isolation rather than modulation of flow, or do you mean a manual diaphragm valve (Saunder's valve)?
Balancing of dust collection systems is best done with good duct design. The Industrial Ventilation handbook is your best reference.

Basically we have 6 rooms with 3 connections in each room. one of the conections in the rooms has a pressure drop of 2500Pa and we are trying to balance the systems. pipe sizes are small and distance are too short to balance the system through static regain.
RE: Dust Collection Balancing
Is is possible to make the duct on the 2500Pa pressure loss section larger to reduce the pressure loss?
