-High through-flow air volume
-Functional design
-Time-saving installation
Filter fans are used to provide an optimum climate in enclosures.
The interior temperature of an enclosure can be reduced by channelling cooler filtered outside air into the enclosure thus expelling heated internal air.
The resulting air flow prevents formation of localised hot pockets and protects the electronic components from overheating.
The plastic usedfor the hood of this filter fan series is highly weather proof and UV light resistant.
Approvals: UL File Nr. E 234324

Roof filter fans and roof exit filters find use in enclosures, from which warm air has to be diverted due to increased heat development.
The ready-to-connect, low-noise roof filter fan, which houses four axial fans, is used to expel warm air from within the enclosure which has been generated by the stray power of the components.
The roof exit filter provides passive ventilation.

Hydrogen Coolant Purifiers - HCP
The HCP is a self-contained system that dries and purifies the hydrogen gas that is used as a coolant in electrical power plant generators. It removes water, oil and other contaminants that cause corrosion and cracking in retaining and zone rings, lead carbonate formation, increased windage losses and other potentially catastrophic consequences.
Legendary Select Series or Century Series control valves feature stainless steel internal parts designed specifically for desiccant dryer service and tested to 500,000 cycles, bubble-tight.
Switching valves and gas-tight blower are vented to prevent formation of dangerous air-hydrogen mixtures.
Welded stainless steel piping minimizes threaded connections, reducing potential leaks.
Complete instrumentation monitors the system for operation outside of specifications.
Potted conduit seals isolate electrical controls from hydrogen.
High temperature heater shutdown prevents excessive operating temperature.
Pre-installed PPC Series pleated particulate filters protect downstream equipment.

Output components for motor protection and the improvement of system reliability, availability and functionality. Deployed at the output side of frequency inverters, these filters ensure reliable operation by avoiding expensive downtimes of installations, manufacturing plants, machinery and
a vast array of other industrial and domestic motor drive applications due to premature motor damage. An appropriate output solution will even allow the deployment of unshielded motor cables, the use of multiple motors in parallel on the same drive or the retrofit of modern drives in existing installations with old motors and unshielded cabling.

FOVT dV/dt Output Filters
Features:
dV/dt Output filter
* Three phase output filter for converters.
* Minimizes frequency converter dV/dt values.
* For long motor cables.
* Reduces motor heating.
* Increases motor life.
General specifications
* Maximum operating voltage: 550Vac ± 15.
* Operating frequency: DC - 60Hz.
* Hipot test voltage:
- L/N-›PE: 3000Vac 2s.
- L-›N: 2250Vdc 2s.
* Application class: HPF Acc. TO DIN 40040
* (-25ºC/+85ºC/95% RH, 30d).
* Flammability class: UL 94 V2.
* Inverter switching frequency: 4-16kHz.
* Max. motor cable length: 50m.
Fast switching between inverter IGBTs causes high voltage ramps (> 4.000V/µs) whcih may be even higher in the motor windings. Fast switching also tends to shorten motor life and limits maximum cable lengths.
Using a PREMO dV/dt EMC filter we guarantee the maximum peak voltage will stay under 1.000V/µs, with a dV/dt value < 500V/µs.
Suppressing voltage peaks like this will also reduce EMI interference from the converter, will increase its life and improve its performance.

Hosokawa's classifiers are engineered to meet industry's increasing need for finer particles and more narrow particle size distribution. Our classifiers are designed to consistently produce particle size distributions that are: uniform and homogeneous; spherical and smooth and dry and easily dispersible. Our broad range of classifiers have application in the pharmaceutical, toner, ceramic, metal powders and plastic industries. Each classifier is designed for easy operation and maintenance. Particle size is easily adjusted by changing rotor speed or airflow and the modular design provides easy access to the classifier's internal components which results in simple product changeover. The unique mechanical design produces high recovery rates of fine particles, up to 90%. The streamlined component design results in lower pressure drop and subsequently

Sweco's Turbo-Screen Air Classifier is the clear choice for separation of dry particulate. It provides continuous, precise screening of dry materials, especially in the finer particle sizes. This unit uses a variety of screen sizes from 60 to 600 mesh for efficient separation of particles ranging from 25 to 300 microns. It can handle the most difficult materials, including electrostatic materials and particles that tend to agglomerate easily.
Unlike a standard air classifier, the Turbo-Screen system provides an absolute cut. This has opened new possibilities for fine-particle separation within a wide variety of industries, including but not limited to food, chemical, powdered metal, plastic, electronics, pharmaceuticals and ceramics.

The Atritor DCM Mill is one of the most universal milling systems available with independently driven grinding and classifying sections.
It has a wide range of applications producing materials in some instances to less than 15 microns.
Feed material is metered into the mill pneumatically and first passes into the classifier zone where any fraction of the feed that is already inside specification is removed as product, thus avoiding any over-grinding. Oversize is recycled internally to the grinding zone and is returned to the classifier after further size reduction. This process produces a steep size distribution curve.
Adjustment of the classifier speed controls the size of the product leaving the mill. The product is conveyed pneumatically to a collecting cyclone and/or bag filter. With the application of heat to the inlet air flow, simultaneous drying can be undertaken.
