Particles collect on the outside surface of the bags as the air stream passes through the filter media and up to the clean air plenum.

At timed intervals a selected solenoid valve actuates a diaphragm valve, releasing a predetermined volume or pulse of compressed air into distribution pipe, producing a shock wave along the length of the bag, flexing the fabric and dislodging dust particles from the surface.

The cleaning cycle can also be initiated by monitoring the differential pressure across the filter media as a result of dust build-up. Referred to as "cleaning on demand," this pulsing system only operates when bags require cleaning, minimizing compressed air consumption and lengthening bag life. Optional Smart Timer™ also available for these units.

Top Access Units: Bags and cages are removed and installed from Flex-Kleen patented Trap 10 above the tube sheet. Our Trap 10 design provides the most effective tube sheet/bag seal available anywhere.

Bottom Access Units: Bags are removed from beneath the tube sheet. Broad range of filter media and surface finishes are available to handle high temperatures, smaller particle sizes, corrosive environments, sticky materials, etc.

Venturis have multiple functions: 1) aspirate filtered air into the bag to create the cleaning pulse, and 2) retard the escape of the pressure wave from the top of the bag, causing multiple and repetitive pulses.
