Mechanical air filtering, using golf ball technology

09 August 2010 - The Recojet 1air filter with its compact outer dimensions and its lightweight casing contains a energy saving, dynamically balanced, high-performance fan with a vacuum safety cylinder and using the patented maintenance-free Cyclone filter system gives you a complete air filtration solution ready for connection, without the traditional problems of centrifugal separators such as noise, low separating rates and strong vibrations the Recojet 1can be mounted directly onto the machine.

The Reven Ultra Cleaner is for use where smoke and other fine particles need to be removed at a higher volume. The Reven Ultra Cleaner allows you to add additional filters with all basic elements easily cleaned for reuse. Its flame-arresting capability has been tested successfully by the German TUV in compliance with the directive UL 1046 of the American Underwriters Laboratories.

The Cyclone filter system used in the Recojet 1is based on the principal of when a golf ball is flying, the highest pressure applies at its front. The dimples on the surface of the golf ball produce pressure compensation between the front and the rear of the ball, thus reducing aerodynamic drag. That is why a golf ball with dimples flies farther than a smooth one.
Similar to the dimples of a golf ball, Reven has applied indentations and dimples to the surfaces that are exposed to the airflow. This helps to optimize the airflow and improves the separating performance of the device by creating in effect miniature cyclones. These cyclones which develop when air moves over the profiles of the X-Cyclone rotate faster, with the same pressure loss, and therefore create a highly efficient separating action sending particles to hit the edge of the profile where they then move down the profile for collection and disposal.

This dispenses with auxiliary energy supply as well as any auxiliary material (fabric, etc.) and is particularly well suited for the separation of the following harmful substances from the air:

Aerosols
Dispersions of fluid droplets and solid particles in a gaseous environment.

Mist
Fluid droplets generated by supersaturated vapour through condensation when the temperatureIpressure decreases.

Vapour
Substances that are generated at normal ambient temperatures when the vapour pressure is below 1.013 mbar.

Fine dust
Solid particles with a diameter below 10 m.

Air pollutants in the form of aerosols, mist or vapour (saturated) as well as fine dust occur in various particle fractions [m]. A particle is a defined mass depending on gravity. These particles are conducted together with the transporting medium air into the X-Cyclone separator by forced ventilation (fan).

Separation then takes place in three stages:
Stage 1 - Pre-separation through turbulences and flow separation occurs in the first chamber.
Stage 2 – The Cyclone effect in chamber 2 with an extremely high medium surface tension, relief and re-establishment of the tension, causes Microparticles to be ejected through the small rotating cyclones.
Stage 3 - The airflow creating these individual cyclones pass through the profiled element in such a manner that two cyclones finally flow into a common chamber.
The separated fluids run vertically off to the bottom of the X-CYCLON element and removed. Most of the separated solid particles run off together with the liquid.

This provides for a self-cleaning effect because the fluid mass ≥ the solid mass.

The resultants savings in the collection of fluids being returned to your equipment and having the removal of the mists and particles from the working environment are an easy justification for the investment. What’s more you no longer have to purchase those throwaway filters and maintenance is now a simple process.
