Dynavane Self-Cleaning Inertial Air Filter
The Parker Farr Dynavane's performance is unequalled! Extensive testing under laboratory and field conditions has proven the Dynavane to be one of the most effective high volume air cleaners for use in pre-cleaning, single and multi-stage filtering systems. It has been demonstrated over many years of application that the Dynavane inertial separator will perform efficiently in a wide variety of operating conditions, at all velocities – from idle through top speed. The Dynavane can remove 10% more airborne contaminants than any competitive unit, resulting in a much cleaner air compartment, generator, traction motor and blower. This inertial separator is designed to provide long, trouble-free service under the most difficult conditions.
The Dynavane is an inertial cleaner that is environmentally friendly, and a sustainable product, as they self-clean and do not require regular replacement associated with typical throw-away barrier filters. The Dynavane is recommended where dust concentrations are extreme or where service work must be minimized.
Inertial separators are highly efficient as a primary air filtration device or as a pre-cleaner for high efficiency secondary filters. Using a sophisticated design, the Dynavane incorporates the principle of inertial separation, providing high dust removal efficiency of airborne particulate matter. Contaminated air enters the inlet and moves down the wedge shaped cells. As the mixture of dust and air enters the Dynavane, most of the air changes direction. As the air changes direction and passes through the side vanes, inertial force separates the contaminants from the air. Because of its greater mass (and inertia), the dust continues in a straight line with 10% of the incoming “bleed air” through the bleed slot, into the dust bin duct. The dust laden bleed air may then be discharged directly back into the surrounding atmosphere, or a secondary dust collector, making this a truly self-cleaning operation. Intake air is efficiently cleaned with minimum resistance due to this specially engineered design.
Over 90% of airborne moisture is removed as the clean air enters the unit. Strategic placement of special water barriers prevents rain or other liquids from migrating through the Dynavane assembly. Less moisture equals fewer electrical problems, reducing maintenance costs.
The Dynavane features rugged construction - fabricated of mild steel or stainless steel or aluminum, these units will provide economical service for years to come. The vanes are computer optimized and individually die-formed, which eliminates the cracking common to stamped louvers in thin steel sheets, and provides superior performance characteristics. The individual vanes are assembled into a totally rigid unit which eliminates flutter, vibration and noise. The wider vane spacing and a longer bleed slot reduce airflow resistance and the chance of plugging, achieving absolute minimum in contaminant penetration and offering a longer service life.
The Dynavane's efficiency is dependent on the size and specific gravity of the dust particles, as well as the air approach velocity and bleed air rate. Large variations in inlet temperature also affect collection efficiency. The Dynavane's effectiveness on dusts with different specific gravities and/or at different air temperatures may be investigated via the size correction charts in the product literature (under the Support Tab). Because temperature effects are secondary, corrections to the Dynavane's performance for normal ambient temperature variations is not necessary.
Dynavane blade packs may require periodic cleaning depending on concentration levels and consistency of contaminants. In these instances the blade packs are easily removed for cleaning. Optional Dynavane construction allows each blade pack to be pulled out and cleaned without removing the entire Dynavane assembly. This unique feature facilitates thorough inspection or service, if necessary. Caution should be exercised in the application of the Dynavane when dealing with oily or sticky contaminants. Additional application and performance information is available from Parker Farr.
Standard, pre-engineered Dynavane assemblies are available in sizes operating from 500 CFM to over 250,000 CFM. Custom engineered models are also available, and can be designed to suit our customer's needs. Multiple units can be combined to handle even greater air volumes with minimal space requirements.
