Superior Design Increases Efficiency and Improves Filter Cartridge Life

The patented Pneumafil Paraflo® horizontal cartridge filter provides superior performance in a wide variety of applications.

Paraflo® Filters are often used in place of baghouses because of their compact size, quick cartridge changes, and the fact that they do not require a confined space entry permit.

What Sets Paraflo® Apart:

The Paraflo utilizes three unique features to achieve superior performance:

Preseparation removes denser particles from the air stream prior to filtration, thereby lowering the amount of material the cartridges must collect and raising the filtration rate.

Parallel Air Flow eliminates high velocity impingement of the particulate stream on the filter media, extending cartridge life.

High Efficiency Pulsing System provides unmatched cleaning performance while minimizing compressed air consumption.

FEATURES AND BENEFITS

1. Parallel airflow with patented inlet extends cartridge life and increases filtration rate.
2. High efficiency pulsing provides highest filtration rate in tough applications.
3. Heavy duty construction and powder painting inside and out provide longer service life.
4. Modular, panelized design allows easy capacity increases. Multiple units share common hoppers and minimize clean air ducting.
5. Complete selection of cellulose, spun bond and membrane filter media permits a cartridge selection to meet the unique needs of each application.

HOW IT WORKS

Unfiltered air enters the top of the collector and is introduced into the filter compartment through a constant velocity, tapered flow header (1). An inlet flow straightener is incorporated which minimizes turbulence, entrance energy losses, and cartridge abrasion. This header and flow straightener redirects air flow (2) to be parallel to the filter cartridges. Gravity and inertia cause heavier particles to continue on a downward path (3) into the hopper.

The lighter, fine dust follows the air stream and accumulates on the outside of the cartridges (4). This causes a pressure drop increase across the cartridge media, which is constantly measured and controlled with a dual setpoint (high-low) photohelic gauge. The cartridges are cleaned by back-pulsing 40-80  PSIG (2.75-5.5 BAR) compressed air through a high efficiency pulsing system to maintain desired . Cartridges are pulse cleaned (5) sequentially top-to-bottom, thereby eliminating excess cartridge-to-cartridge dust re-entrainment and maximizing filtration rate. The loosened dust falls into the hopper.

Clean air from inside the cartridges exits into the clean air plenum (6) and can be returned to the plant in most applications, reducing heating and air conditioning expense.
