Compact Bin Vent

Bin Vents 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.).  Bin vents are easily installed requiring no ductwork, and their compact design allows for installation in tight areas.  Pleated filter cartridges are the most common method for air filtration in compact bin vents.  Effective cartridge cleaning can separate a good bin vent from a bad one.  Most units feature an air pulse cleaning system where short blasts of air are pulsed down the filter cartridges to knock off collected dust.  Bin Vents that feature a minimum 3 filter cartridge design, with filter cartridges that have sufficient spacing in between pleats are cleaned more effectively which greatly increases the filter cartridges lifespan.

JDB Bin Vent Features

JDB Dense Flow Compact Bin Vents are built tough, and feature filter cartridges with wide pleat spacing and the most efficient filter media available.  Combined with the individual air pulse cleaning system and minimum 3 cartridge design our units have increased filter lifespans which minimize downtime, and overall maintenance costs.  A variety of models and designs are available, allowing each bin vent to be custom tailored to fit the varying needs of each application.

Filter Cartridges

bin vent filter cartridge specification downloadDense Flow Compact Bin Vents features highly efficient filter cartridges made from Spun Bond Polyester coated with a PTFE membrane.  Spun Bond Polyester is a heavy duty 100% synthetic filter media with high strength, and efficiency.  PTFE (Polytetrafluoroethylene) is essentially a Teflon coating on the Spun Bond filter media.  The PTFE membrane enhances dust release for superior cartridge cleaning.  Spun Bond Cartridges with PTFE score the highest efficiency or MERV rating of 16.  MERV is a measure of filter efficiency (1-16) over a range of different particle sizes.  Testing on the Dense Flow Filter Cartridges shows a 99.997% efficiency rating at a 0.5 Micron particle size.  

The cartridges also feature a wide pleat design that allows them to be more effectively cleaned, and translates into longer cartridge lifespans.  Many competitors will narrow the spacing between pleats in an effort to “pack” more cloth area into a single cartridge.  The thought is that the more cloth area you can fit onto a cartridge, the higher the flow rate the cartridge will be able to handle.  Initially this would be true, but after a short period of use, a cartridge with narrow pleat spacing will be cleaned less effectively and greatly reduce the true or working cloth area of the cartridge.

Air Pulse Cleaning System

The Dense Flow Compact Bin Vent features an air pulse cleaning system, and minimum 3 cartridge design to insure effective cartridge cleaning.  The air pulse cleaning system requires a minimum 60 psi, and 15 CFM of clean, dry air.  Diaphragm valves pulse short blasts of air down the center of the bin vent filter cartridges at individual timed intervals.  The air blasts effectively release dust fines back into the storage bin or silo the bin vent is mounted on.  The pulse timing is controlled through a timer control box mounted on the bin vent housing where pulse length and time between pulses can be adjusted.    

The minimum 3 cartridge design in JDB Dense Flow Compact Bin Vents insures effective cartridge cleaning.  Bin vents designed with one or even two cartridges cannot effectively clean while air is passing through them.  In a one cartridge unit the air being vented has only one place to go, so when a single unit is pulsed for cleaning, and is under a load (or air is passing through the cartridge) the dust will jump off and be forced right back onto the cartridge.  Similarly, when a two cartridge unit is pulsed for cleaning material will jump from the cartridge being pulsed to the other cartridge which is now the only place for the exhaust air to go.  A minimum three cartridge design insures while one cartridge is being pulsed for cleaning, there are two cartridges effectively venting the incoming exhaust air.  In a three cartridge unit each cartridge is more effectively cleaned, which will increase the cartridges working efficiency (efficiency rating after a period of use), and in turn increase the lifespan and effectiveness of each cartridge.

Cartridge Removal

The design of the Dense Flow Bin Vent allows operators and/or maintenance personnel easy access to the units filter cartridges through either a hinged door with captive handles or removable top plate held in place with a clamp.  Depending on the bin vent model cartridges are removed either out of the top of the unit or by sliding a rack out of a door on the front of the unit.
