Efficiency & Economy in a compact package

Designed to maximize efficiency while minimizing maintenance, Griffin’s Cartridge Silo Filter Vents are a compact solution for a wide-range of dust collection applications. Our ultra-efficient cartridges capture 99+% particulate emissions down to 1 micron from the silo while our powerful pulse jet system keeps the filters performing at their best. And without any internal moving parts, maintenance is kept to a minimum.

Like all of our dust collection systems, these units are built to be exceptionally rugged and ready to stand up to heavy-duty use. With a wide range of options, they'll bring you the flexibility to meet your application needs.

Save time with simpler filter change-outs

Simply loosen two swing-bolts, swing the roof up and away, loosen the hold-downs and replace the cartridges.

Flexible designs to meet the toughest conditions

Our standard Cartridge Silo Vents are designed with external pulse components (left), be we also manufacture units with internal components (right) when weather related corrosion is a factor. This means ultimate flexibility no matter where your silo is located.

Automatic Overfill Control System

The Griffin Overfill Control System, consisting of a closing valve, limit switch and control panel, completely automates silo filling and venting while preventing overfill and resulting damage. It is designed to operate on any pneumatic silo filling system with any number of fill pipes. If the high bin signal is clear when the trucker connects his hose to the fill pipe, the butterfly valve will open and the silo will accept material. When the high bin indicator is activated, an alarm will sound telling the trucker to stop his unloading operation. In 90 seconds the butterfly valve will close, sealing off the fill pipe and making it impossible for the trucker to continue pumping in material. The bags in the dust collection system will then automatically shake.

Options & Accessories

• Fans: available as required. Suitable for grade level or side mounting on collector.
• Hopper: Barrel hopper assembly, standard 60 degree slope with flanged discharge and support legs.
• Filter Media & Finishes: Griffin offers state-of-the-art filter media and finishes to ensure optimal efficiency for your collector.
• Automatic Overfill Control: Bin level indicator, pressure safety valve and alarm bell.

This is performance and reliability in a compact package that fits anywhere. But installation flexibility isn't the only benefit of Griffin's cartridge collectors. They also deliver high filtration efficiency with minimal pressure drop. And with true down flow operation and vertically mounted filters, there is less dust re-entrainment. As a result, our Vect-Aire collectors are ideal for in-plant dust and product recovery.

Design Features

• 10 standard models
• 100 cfm to 20,000 cfm
• Media area from 70 sq.ft. to 12,000 sq.ft.
• Housing and hopper constructed of continuously welded HRS

Vect-Aire Flow Pattern

1. From entry to discharge, dust always travels downward between vertical cartridge filters, never impeded by counter flowing air.
2. Light dust particles are collected on outer cartridge surfaces while heavier particles are driven downward to hopper.
3. Unlike horizontal cartridges, vertical filters are uniformly effective over the entire surface.
4. Venturi assisted jet pulse cleaning assures minimum recapture of dislodged dust during cleaning cycle.
5. Dust entering at the top of the collector won't disturb dust already settled in the hopper.
