Eco Quad

Eco Quad dust collection systems are a low cost, low maintenance solution for separating clean air from dust laden air, and are commonly installed on storage bins or silos that require venting for a pneumatic conveying system (Dense Phase, Dilute Phase, Truck Unloading, etc.).

JDB Dense Flow Eco Quad units are built tough, and feature filter cartridges with wide pleat spacing and the most efficient filter media available. Superior dust release is achieved by combining filters with a PTFE membrane and an advanced individual air pulse cleaning system that results in increased filter lifespans which minimize downtime, and overall maintenance costs.
